BackgroundMedial pivot total knee arthroplasty aims to restore native knee kinematics through highly conforming medial tibiofemoral articulation with survival comparable to contemporary knee designs. The aim of this study was to report preliminary clinical results of medial pivot total knee arthroplasty in an Indian population.MethodsA retrospective analysis of 45 patients (average age, 62 years; 40 women and 5 men) with end-stage arthritis (Kellgren-Lawrence grade 4) operated with a medial pivot prosthesis was done. All patients were assessed using Knee Society Score (satisfaction, expectation, and functional scores) and Oxford Knee Score, and range of motion was recorded at the end of 5-year postoperative follow-up. In addition, all patients underwent standardized radiological assessment.ResultsAt the final follow-up, patients reported significant improvement in mean Knee Society Score (satisfaction, expectation, and functional scores) and Oxford Knee Score (p < 0.05). The mean range of motion achieved at the end of 5 years ranged from 0° (extension) to 118.4° (further flexion). There was no evidence of loosening or osteolysis at a minimum follow-up of 5 years.ConclusionsThese results demonstrated satisfactory clinical and radiological outcomes at 5 years after total knee arthroplasty with a medial pivot design, which may be related to better replication of natural knee kinematics with the medial pivot knee and inherent advantages of this design. 相似文献

PurposeSchenck IV knee dislocation patients have dissatisfactory knee function and return‐to‐sport rate with the existing treatment methods. The purpose of this study was to illustrate a one‐stage arthroscopic multiple ligament reconstruction method for treating Schenck IV knee dislocations.MethodsA retrospective case series study was performed. All patients with a history of Schenck IV knee dislocation who underwent one‐stage arthroscopic multi‐ligament reconstruction from 2010 to 2018 were followed for 24 months. The outcomes, including general patient data, Lysholm scores, International Knee Documentation Committee (IKDC) scores, visual analog scale (VAS) pain scores, knee active range of motion, and complications, were reviewed. The data was analyzed with paired‐samples t‐test.ResultsA total of 12 patients, comprising nine males and three females, were followed up and reviewed. The mean age at the time of the surgical procedure was 40.3 ± 9.0 (22–57) years. The mean body mass index (BMI) was 24.6 ± 4.9 (15.2–32.5) kg/m2. The mean IKDC score and Lysholm score before surgery were 30.4 ± 6.1 (21–42) and 28.2 ± 6.2 (22–39), respectively. The average operation time was 121.8 minutes. The mean IKDC score and Lysholm score at the 24‐month follow‐up were 80.6 ± 6.5 (68–92) and 82.0 ± 7.5 (72–95), respectively. There were significant differences in the IKDC and Lysholm scores between the preoperative and 24‐month postoperative time points (p < 0.01). The mean knee range of motion was 124.6° ± 6.6° (115°–135°) at the 24‐month follow‐up. No major complications occurred.ConclusionsThe results of this retrospective study suggest that the new arthroscopic one‐stage multi‐ligament reconstruction technique is an effective way to treat Schenck IV knee dislocation with satisfactory postoperative knee function. 相似文献

ObjectiveTo evaluate knee scores and clinical efficacies of patients with non‐lateral unicompartmental knee osteoarthritis (OA) who randomly underwent mobile‐bearing (MB) unicompartmental knee arthroplasty (UKA), fixed‐bearing (FB) UKA, and total knee arthroplasty (TKA).MethodsFrom September 2015 to February 2017, a prospective, randomized, parallel, single‐center trial of 180 patients (78 males and 102 females; 63.3 ± 6.9 years) with non‐lateral compartmental knee OA was performed in the first author‐affiliated hospital. The patients were randomly divided into three groups (each group included 60 patients) and received medial cemented Oxford phase 3 MB UKA, medial cemented Link FB UKA, or cemented DePuy Sigma PFC TKA, respectively. A similar perioperative management and fast‐track surgery program was carried out for all patients. The knee scores at 3‐year follow‐up after operation and clinical efficacies of these three groups of patients were recorded, investigated, and compared.ResultsPrimarily, compared to the TKA group, the UKA groups (MB UKA and FB UKA) had shorter operative time (median 63.2 < 67.1 min), less bleeding (8.6 < 30.0 mL), earlier resumption of walking without crutches (3.0 < 8.0 days) and walking up and down the stairs (5.0 < 10.0 days) (P < 0.001), higher FJS scores (78.0 > 74.5) (P = 0.007), better results in all knee scores (except VAS and KSS function scores) (P < 0.05), and a larger maximum flexion angle of the knee at the 3‐year follow‐up (123.0° > 96.0°) (P = 0.001). Secondarily, compared to the TKA group, the MB UKA group showed better results in the Western Ontario and McMaster Universities index (WOMAC) stiffness (83.6 > 79.6), WOMAC total (86.3 > 83.2), Oxford knee score (OKS) (20.0 < 23.0), Forgotten Joint Score (FJS) (78.5 > 74.5), and a larger maximum flexion angle of the knee (123.0 > 96.0) (P < 0.05). Moreover, the FB UKA group showed higher Hospital for Special Surgery Knee Score (HSS) (91.0 > 88.5), WOMAC stiffness (84.3 > 79.6), WOMAC function (85.2 > 81.7), WOMAC total scores (87.6 > 83.2), and a larger maximum flexion angle of the knee (119.0° > 96.0°) than the TKA group (P < 0.05). Overall, there was no significant difference in all knee scores and maximum flexion angles of the knee for the MB UKA and FB UKA groups (P > 0.05). There was one case with original bearing dislocation in MB UKA group. One patient with displacement of the femoral component caused by a fall injury, and another patient, who lost his life in a car accident, were involved in the FB UKA group. There was an infection case and an intermuscular vein thrombosis case in TKA group.ConclusionUKA showed more advantages than TKA; however, there was no significant difference between the MB UKA and FB UKA groups for treatment of non‐lateral compartmental knee OA. 相似文献

PurposeThis article prospectively examines the functional outcome measures following management of vascular insult secondary to paediatric supracondylar humerus fractures (SCHFX) using validated outcome measures.MethodsThe three-year, prospective, IRB-approved study consecutively enrolled operative SCHFX patients. Clinical data included presence and symmetry of the radial pulse in injured and uninjured extremities, Doppler examination of non-palpable (NP) pulses and perfusion status of the hand. Pediatric Outcomes Data Collection Instruments (PODCI) and the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) Measures were used to assess functional outcome at final follow-up. Multiple regression analysis was used to determine the relationship between the presence of a vascular abnormality and functional outcome while controlling for other injury parameters.ResultsA total of 146/752 enrolled patients (mean age 6.8 years; range 2 years to 13 years) completed functional outcome measures at final follow-up. Of these, 20 (14%) patients had abnormal vascular exams at presentation: nine (6%) with palpable asymmetric pulse and 11 (7.5%) with NP pulse. Of those with NP pulses, nine/11 (6%) were Dopplerable and two (1.5%) lacked identifiable Doppler signal. Patients with a symmetric, palpable pulse demonstrated better PODCI pain and comfort scores (95.2 versus 85.2) (p < 0.0001), and QuickDASH scores (10.9 versus 21.6) (p < 0.007) compared to those with any abnormal vascular examination. Patients with palpable pulses, regardless of symmetry, demonstrated significantly higher PODCI pain and comfort scores (94.6 versus 84.7) (p < 0.003) than NP pulses.ConclusionsIn children with operative SCHFX, an abnormal vascular examination at presentation is predictive of poorer outcomes in pain and upper extremity function. A palpable pulse, versus NP, is predictive of better pain and comfort at final follow-up.Level of evidenceII 相似文献

BackgroundBoth medial pivot (MP) and rotating platform (RP) mobile-bearing (MB) total knee arthroplasty (TKA) have been developed to better mimic the natural knee kinematics and femoral roll back in flexion. The purpose of this retrospective study was to compare the mid-term functional outcomes and range of motion (ROM) of MP and RP types of total knee arthroplasty.Methods116 patients (mean age of 66.3 years) undergoing TKA (52 Medial pivot design and 64 Rotating Platform design) were evaluated retrospectively with Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) knee score, knee society score (KSS) with its subgroups namely, Knee Score (KSKS) and Functional Score (KSFS) and forgotten joint score (FJS) at a mean follow-up of 7.1 years. Range of motion (ROM) and tibiofemoral anatomic angle on the radiographs were also compared.ResultsMean ROM, WOMAC and KSKS improved significantly from pre-operative to postoperative knees in both the groups. There was, however, no significant difference between the two groups at the final follow-up. In contrast, mean KSFS score improved to 89.5 ± 8.1 in MP group and 86.3 ± 7.1 in RP Group (p = 0.025), while mean FJS was 85.6 ± 4.1 and 80.9 ± 5.4 in the MP and RP groups, respectively (p = < 0.0001).ConclusionSatisfactory clinical and functional outcomes can be obtained using either a MP or RP knee joint in tricompartmental osteoarthritis of knee. The MP design scores better on the KSFS score and FJS than the RP-TKA. 相似文献

ObjectiveTo investigate the effect of platelet‐rich plasma on tendon‐bone healing after anterior cruciate ligament reconstruction.MethodsThis retrospective study included 85 patients (range, 18–50 years; mean age, 33.95 ± 10.53 years; male/female, 49/36) who underwent anterior cruciate ligament reconstruction using autologous hamstring tendons between August 2017 and June 2019 at our institute. The participants in the study group (n = 42) were injected with platelet‐rich plasma at both ends of the tendon graft, while those in the control group (n = 43) received an injection of normal saline. Magnetic resonance imaging signal/noise quotient values of the femoral and tibial ends, knee Lysholm scores, and International Knee Documentation Committee scores were compared at 3, 6, and 12 months postoperatively.ResultsThe signal/noise quotient values of the femoral and tibial ends in both groups were higher at 6 months than at 3 and 12 months postoperatively. The signal/noise quotient values of the tibial end were significantly lower in the platelet‐rich plasma group than in the normal saline group at all follow‐up time points (P < 0.05). The signal/noise quotient values of the tibial and femoral ends in both groups were significantly different at 3, 6, and 12 months postoperatively (P < 0.05). Additionally, the signal/noise quotient values of the tibia were significantly lower than those of the femur in both groups (P < 0.05). The Lysholm and International Knee Documentation Committee scores were significantly better in the platelet‐rich plasma group than in the normal saline group only at 3 months postoperatively. No complications, such as knee joint infection or vascular and nerve injuries, occurred in any of the 85 patients. The knee flexion of all patients were more than 90°, and the straight degree was 0°. No joint stiffness was observed in all patients.ConclusionPlatelet‐rich plasma can promote tendon‐bone healing in grafts and can improve early postoperative knee joint function. 相似文献

IntroductionClinical outcome measures are important in both the conduct of clinical research and evaluation of knee surgery in every day clinical practice. A wide variety of validated outcome scores are available in the literature. The objective of this study was to investigate if there is a difference between clinician-completed and patient-completed outcome scores in detecting improvement following anterior cruciate ligament (ACL) reconstruction.MethodsFifty patients with ACL rupture were prospectively evaluated using nine clinical outcome measures. Five clinician-completed knee scores included Tegner Activity Score, Lysholm Knee Score, Cincinnati Knee Score, International Knee Documentation Committee (IKDC) Objective Knee Score and Tapper and Hoover Meniscal Grading Score. Four patient-completed knee scores included IKDC Subjective Knee Score, Knee Outcome Survey - Activities of Daily Living Scale (KOS-ADLS), Short Form-12 Item Health Survey (SF-12) and Knee Injury and Osteoarthritis Outcome Score (KOOS). Thirty-four of the 50 patients underwent an ACL reconstruction and were reassessed with all nine outcome scores upon their follow-up review 3 months post-operatively.ResultsA significant longitudinal improvement was observed of all five clinician-completed knee scores including Tegner (3.3–4.1 (p = 0.006)), Lysholm (71.7–85.3 (p < 0.001)), Cincinnati (62.6–75.9 (p < 0.001)), IKDC Objective (Abnormal to Nearly Normal (p = 0.001)) and Tapper and Hoover (Fair to Good (p < 0.001)). However, none of the four patient-completed knee scores revealed a statistically significant improvement post-operatively.ConclusionsResults of clinician-completed scores were found to be inconsistent with those of patient-completed instruments. It's important to consider the mode of administering outcome measures either for research or clinical practice as it can have a significant influence on the end results. The use of both a clinician-completed and a patient-completed instrument maybe the more prudent approach to assessing and quantifying ACL injuries and the outcome post-operatively. Ultimately, better methods of objectively evaluating surgical interventions of the knee are required. 相似文献

Objective:This study aimed to evaluate the efficacy and safety of intravenous combined with topical application of tranexamic acid (TXA) in reducing blood loss in opening wedge high tibial osteotomy (OWHTO).Methods:A total of 60 patients who underwent unilateral OWHTO between May 2018 and May 2019 were retrospectively reviewed. All the patients were then divided into one of the two groups (30 per group): the TXA group, patients receiving intravenous combined with topical application of TXA, and the control group, patients receiving no TXA. Outcome measures were drain volume, total blood loss, hidden blood loss, transfusion requirements, and incidence of complications.Results:The mean follow-up of TXA group was 14.2 2.3 months (range, 13-16 months) and the mean follow-up for the control group was 14.4 2.1 months (range, 13-17 months). No significant difference was found for the follow-up of two groups (P = 0.829). Drainage volume (143.3 65.4 ml vs 307.8 51.4 mL, P < 0.001), hidden blood loss (156.7 63.8 mL vs 286.4 79.1 mL, P < 0.001) and knee swelling (3.2 0.9 vs 6.5 2.1, P < 0.001) in the TXA group was clearly less than that in the control group, and there was no statistical significance with regard to hospitalization time (P = 0.746), transfusion requirements (P = 1.000), wound complications (P = 0.386), deep venous thrombosis (P = 1.000), postoperative Lysholm knee score (P = 0.681) and Knee Injury & Osteoarthritis Outcome subscales pain (P = 0.752), symptoms (P = 0.673), activities of daily living (P = 0.871), sport/recreation function (P = 0.816), and knee-related quality of life (P = 0.576) at 6 months postoperatively.Conclusion:This study has shown that administration of intravenous combined with topical TXA in OWHTO can effectively reduce perioperative blood loss without increasing the incidence of postoperative complications. 相似文献

PurposeComparison of two hexapod frame systems in paediatric tibial deformity correction; the Taylor Spatial Frame (TSF) and Orthex Hexapod System.MethodsPaediatric patients with congenital and acquired tibial deformities treated with either TSF (between 2014 and 2016) or Orthex (between 2017 and 2019) frames were included in a retrospective comparative study. Outcome measures were healing index, pin infection rate, regenerate quality and density, software residual rate, deformity correction accuracy, strut exchanges and quality of life (QoL).ResultsThe TSF group had 17 patients (18 frames) and the Orthex group had 21 patients (25 frames). The most common indications for tibial deformity correction were fibular hemimelia (14) and septic or traumatic growth arrest (8). The median time in frame was 230 days (TSF) versus 203 days (Orthex) (p= 0.06). The mean lengthening achieved was 54 mm (TSF) and 51 mm (Orthex) (p = 0.41). The healing index was 41 days/cm (TSF) versus 43 days/cm (Orthex) (p = 0.70). Pin site infections occurred more in the TSF cohort (40%) than in the Orthex cohort (18%) (p < 0.001). The regenerate in the Orthex group showed higher density at three months (p = 0.029) and was more homogenous (p = 0.023) at six months after frame application. Strut exchanges were less frequent with the Orthex system (p < 0.0001). QoL measures were similar in both cohorts (p = 0.92).ConclusionsThis is the first study to compare two hexapod designs in paediatric orthopaedics. The Orthex system showed superiority in regenerate quality and a significant reduction in pin site infection rates. Both systems delivered predictable and accurate limb deformity correction.Level of evidenceIII 相似文献

ObjectiveCartilage defect is a common pathology still lacking a unified treating option. The purpose of this retrospective study is to evaluate the safety, efficacy, and clinical and radiological outcome of cartilage restoration of knee joint with allogenic next‐generation Matrix‐Induced Autologous Chondrocyte Implantation (MACI) for the first time, as well as the correlation between postoperative clinical and radiological outcomes and preoperative patient history and demographics.MethodsFrom July 2014 to August 2020, 15 patients who went through cartilage restoration with allogenic next‐generation MACI were included in this study. Patient demographics and PROM including the International Knee Documentation Committee (IKDC) subjective knee score, Lysholm score, Tegner Activity Scale (TAS), and Knee Injury and Osteoarthritis Outcome Score (KOOS) were obtained preoperatively, at 3, 6, 12 months postoperatively and the last follow‐up using an online questionnaire platform. MOCART 2.0 score was calculated at the last follow‐up. Analysis of variance (ANOVA) was used to compare PROM pre‐ and post‐operation, with two‐tailed p < 0.05 defined as statistical significant. Pearson correlation coefficient was used to evaluate correlation between the PROM and MOCART 2.0 score at the last follow‐up with patients demorgraphics.ResultsAll patients were followed for an average of 66.47 ± 24.15 months (range, 21–93). All patients were satisfied with the outcome of the surgery and no complication was reported at the end of the study. No significant improvement was observed until 1 year after the implantation, except for IKDC score at 6 months. All PROM showed significant improvement 1 year post‐op except for Lysholm score and TAS, which also increased significantly at the time of the last follow‐up. Pearson correlation coefficient showed that the size of the defect, before or after debridement, was significantly negatively correlated with final KOOS‐Pain (before debridement: r = −0.57, p < 0.05; after debridement: r = −0.54, p < 0.05) and KOOS‐Symptoms score (before debridement: r = −0.66, p < 0.05; after debridement: r = −0.67, p < 0.05). The MOCART 2.0 score was found significantly and negatively correlated with BMI (r = −0.60, p < 0.05), and significantly and positively correlated with Lysholm score (r = 0.70, p < 0.05).ConclusionThe next generation MACI with autologous chondrocyte and allogenic chondrocyte ECM scaffold could be used to treat focal articular cartilage defect in the knee joint safely and efficiently with lasting promising outcomes for more than 5 years. The size of the defects should be considered the most negatively correlated parameters influencing the postoperative clinical outcomes. 相似文献

Background/PurposeForgotten Joint Score (FJS) is designed to asses patient recovery post Total Knee Arthroplasty (TKA) in a new dimension. It assess the ability to forget the operated joint as artificial during activities of daily living. New Knee Society Score (NKSS) is developed to encompass objective and subjective outcome as well as an assessment of patient expectation and satisfaction. Our purpose was (1) to determine FJS at 1 year post TKA in Indian Patients, and (2) to assess convergent validity between FJS and the NKSS. We hypothesised that FJS should strongly correlate with the Satisfaction (SS) and Knee perception(KPS) sub-component of NKSSMethodsWe enrolled 181 patients who underwent primary TKA during an 8-month duration. They were prospectively followed up at 1-year review clinic when FJS and NKSS were administered. 169 patients completed the assessment forms and 13 patients were lost to follow-up. Statistical evaluation was done with Spearman correlation test.ResultsMean FJS at 1 year was 66.6 ± 25.9 with 14% ceiling and 1% floor effects. There was a mild to moderate correlation of FJS with NKSS (p < 0.001, r = 0.47) and its sub-scores (p < 0.001; r = 0.43 and r = 0.44). There was a weak correlation of FJS with NKSS sub-components of SS and KPS (p < 0.001; r = 0.37 and 0.25, respectively).ConclusionMean FJS at 1 year post TKA showed convergent validity with NKSS; however, the correlation was not strong enough to use them interchangeably. Hypothesis that FJS should strongly correlate with the NKSS sub-components of satisfaction and joint perception was refuted. We conclude, FJS provides unique evaluation in recovery post TKA, different from NKSS.Level of EvidenceLevel III. 相似文献

ObjectiveTo examine the incidence and risk factors of in‐hospital prosthesis‐related complications (PRCs) following total knee arthroplasty (TKA) using a large‐scale national database.MethodsA retrospective database analysis was performed based on Nationwide Inpatient Sample (NIS) from 2005–2014. Patients who underwent TKA were included. The recruited cases were divided into two groups according to the occurrence of PRCs. Patient demographics (age, sex, and race), hospital characteristics (type of admission and payer, and bedsize, teaching status, location, and region of hospital), length of stay (LOS), total charges during hospitalization, in‐hospital mortality, comorbidities, and perioperative complications were analyzed.ResultsA total of 1,227,244 TKAs were captured from the NIS database. There were 8484 cases of in‐hospital PRCs after TKA and the overall incidence was 0.69%, with a slight downward trend annually. Periprosthetic joint infection (PJI) was the main category among PRCs (0.20%), followed by mechanical loosening (0.04%), dislocation (0.02%), and periprosthetic fracture (PPF) (0.01%). Patients suffered from in‐hospital PRCs were 3 years younger (64 years vs 67 years) and 6.51% more likely to be male (43.60% vs 37.09%) compared to the nonaffected population (P < 0.0001). Additionally, patients experiencing in‐hospital PRCs after TKA were 2.11% less likely through elective admission (92.07% vs 94.18%) while 2.34% more likely in teaching hospital (45.53% vs 43.19%) than those without these complications (P < 0.0001). Furthermore, the occurrence of in‐hospital PRCs was associated with longer LOS (4 days vs 3 days; P < 0.0001), more total charges ($53,418 vs $41,204, P < 0.0001), and higher in‐hospital mortality (0.30% vs 0.07%; P < 0.0001). Multivariate logistic regression was performed to identify independent risk factors of in‐hospital PRCs after TKA which included younger age, male, non‐elective admission, teaching hospital, deficiency and chronic blood loss anemia, coagulopathy, congestive heart failure, depression, diabetes with chronic complications, fluid and electrolyte disorders, pulmonary circulation disorders, metastatic cancer, and weight loss. Besides, in‐hospital PRCs after TKA were associated with secondary osteoarthritis, inflammatory arthritis, prior knee arthroscopy, acute renal failure, acute myocardial infarction, deep vein thrombosis, sepsis, transfusion, and wound dehiscence.ConclusionIt is beneficial to study the risk factors of in‐hospital PRCs after TKA to ensure the appropriate management and optimize consequences although a relatively low incidence was identified. 相似文献

Objective:This study aimed to evaluate the mid-term clinical outcomes of total knee arthroplasty (TKA) in the management of end-stage hemophilic arthropathy.Methods:Eleven patients (15 knees) undergoing TKA with stiff knees were retrospectively evaluated. TKA was performed in all patients without additional surgical interventions such as posterior capsular release, hamstring release, synovectomy, VY quadricepsplasty, or tibial tubercle osteotomy. All patients were evaluated for clinical and radiological results at follow-ups. Functional evaluation and pain status were assessed using the Knee Society Score and Visual Analogue Scale.Results:The mean age at the time of operation was 40.8 ± 11.8 years (range = 30–64 years). The mean follow-up was 51.2 ± 20.6 months (range = 24–95). The mean flexion contracture significantly decreased from 17.6 ± 11.3 to 1.7 ± 2.8 degrees, and the mean maximum flexion increased dramatically from 55.6 ± 20.5 to 109.2 ± 16.2 degrees (P < 0.001). Statistical significant improvement in flexion and flexion contracture degrees continued up to the postoperatively 18 months. The mean Knee Society Score increased from 22.7 ± 2.4 points preoperatively to 87.8 ± 3.8 points at the last follow-up (P < 0.001). The mean cost of coagulation factor consumption and blood transfusion accounted for 78% of the total cost. Conclusion:This study has shown that TKA is an effective treatment for relieving pain and improving both ranges of motion and quality of life in managing end-stage hemophilic arthropathy of the knee joint.Level of Evidence: Level IV, Therapeutic Study 相似文献

PurposeThis study aimed to compare the clinical and radiographic outcomes of patients with positive patch tests undergoing a medial mobile-bearing titanium–niobium nitride (TiNbN) unicompartmental knee arthroplasty (UKA) to patients undergoing standard UKA (cobalt–chromium [CoCr] implants).MethodsTwo successive groups of patients, amounting to a total of 246 individuals, who received Oxford (Zimmer-Biomet, Warsaw, Indiana, USA) UKA were included. The first group was composed of a series of 203 consecutive standard CoCr UKAs (Standard Group), while the second group comprised 43 consecutive hypoallergenic TiNbN UKAs (HA group). The patients of the second group had a positive epicutaneous patch test result for metals. Each patient was evaluated using the Oxford Knee Score (OKS) and Knee Society Score (KSS) a day prior to the surgery (T0) and at two consecutive follow-ups, namely T1 (minimum follow-up of 12 months) and T2 (minimum follow-up of 34 months).

ObjectivesA posterior cruciate ligament (PCL) avulsion fracture of the tibial attachment site is a specific type of PCL injury that is difficult and unpleasant to manage. The objective of this study is to report the preliminary results of a newly developed technique: arthroscopic endobutton‐suture fixation using a single tibial tunnel.MethodsFrom January 2016 to January 2018, 120 patients with PCL avulsion fracture who met our criteria were recruited. Sixty cases were treated by arthroscopic direct anterior‐to‐posterior suture suspension fixation (endobutton‐suture group), and 60 cases were treated by arthroscopic screw‐suture fixation (screw‐suture group). All radiographic studies were recorded. The curative effect was evaluated by the range of motion (ROM), KT‐2000, International Knee Documentation Committee (IKDC) scores, Tegner activity scale, and Lysholm scoring system. For statistical analysis the Student t‐test was used.ResultsThe average follow‐up duration was 24 months. Findings and difficulties in surgery are the following. The lax anterior cruciate ligament is one of the diagnostic criteria. The anatomic location of PCL avulsion fractures is deep and surrounded by nerves and vessels; thus, operating through this region is difficult. After each tunnel drilling, the debris at the edge of opening needs to be cleaned to avoid obscuring the operator''s vision or wearing the sutures. In endobutton‐suture group, ROM improved from 0° preoperatively to 140.0° ± 5.6° at the last follow‐up (P < 0.001). The postoperative KT‐2000 arthrometric data at 90 N were available for all patients. The IKDC score was 23.6 ± 2.6 and 91.4 ± 4.1 pre‐ and postoperatively, respectively. The Tegner score improved from 1.2 ± 0.6 to 7.3 ± 2.3 (p < 0.001). The median Lysholm knee score increased from 40.4 ± 5.2 preoperatively to 90.1 ± 10.1 postoperatively (p < 0.001). The operative time was shorter in the endobutton‐suture group (p < 0.001). The Lysholm knee score in the endobutton‐suture group was lower than that in the endobutton‐suture group (3.1 ± 1.2 vs. 4.2 ± 1.8, p < 0.01). No significant complications were noted in the study.ConclusionsThe arthroscopic direct anterior‐to‐posterior suture suspension fixation is a simple and reliable method that not only provides better clinical outcomes, but also fixes avulsion fragments of any size. 相似文献

BackgroudOne recently developed total knee arthroplasty (TKA) prosthesis was designed to alter the patellofemoral geometry and optimize patellar tracking compared to its predecessor. Despite an expectation that the improved design would contribute to optimal patellofemoral compatibility, its effect has not been confirmed with patellofemoral-specific clinical scoring systems and radiographic parameters. Our purpose was to compare patellofemoral-specific clinical and radiographic results after TKA using a patellofemoral design-modified prosthesis and its predecessor.MethodsThe results of 200 TKAs with Attune (group A) were compared to those of 200 TKAs with PFC Sigma (group B). Clinically, the presence of anterior knee pain (AKP), patellar crepitation, and Kujala score were checked. Radiographically, anterior femoral offset (AFO), posterior femoral offset (PFO), position of patellar ridge, and patellar tilt and translation were compared.ResultsIn group A, AKP and patellar crepitation occurred less frequently (AKP: 3% vs. 8%, p = 0.028; patellar crepitation: 2.5% vs. 9%, p = 0.005) and Kujala score was higher (81.8 vs. 77.9, p < 0.001), when compared to group B. The AFO decreased in group A postoperatively but increased in group B (−1.2 vs. 1.1 mm, p < 0.001). The change in PFO was smaller in group A than group B (−1.2 vs. −3.6 mm, p < 0.001). The change in patellar ridge after TKA was smaller in group A than group B (1.4% vs. 8.3%, p < 0.001). The postoperative patella of group A was more laterally tilted (5.9° vs. 2.2°, p < 0.001) and less laterally translated (0.9 vs. 2.6 mm, p < 0.001). The proportion of incompatible patella tilt angle (≥ ± 10°) was greater in group A than group B (21.7% vs. 4.5%, p < 0.001).ConclusionsTKA using Attune provided better patellofemoral-specific clinical results and favorable radiographic parameters related with patellar ridge, AFO, and PFO than TKA using PFC Sigma did. However, the current prosthesis did not provide better radiographic patellar tracking, which might be due to the medial location of the patellar ridge. 相似文献

Background:
The anterior cruciate ligament (ACL) is one of the major stabilizing factor of the knee that resist anterior translation, valgus and varus forces. ACL is the most commonly ruptured ligament of the knee. The graft fixation to bone is considered to be the weakest link of the reconstruction. According to the parallel forces to the tibial drill hole and the quality of tibial metaphyseal bone is inferior to femoral bone stock, graft fixation to the tibia is more difficult to secure. AperFix system (Cayenne Medical, Inc., Scottsdale, Arizona, USA) which consists femoral and tibial component that includes bioinert polymer polyetheretherketone (PEEK) is one of the new choice for ACL reconstruction surgery. aim of this study was to assess the clinical outcomes and fixation durability of the AperFix (Cayenne Madical, Inc., Scottsdale, Arizona, USA) system and to determine the effect of patient''s age in arthroscopic reconstruction of the anterior cruciate ligament.Materials and Methods:
Patients with symptomatic anterior cruciate ligament rupture underwent arthroscopic reconstruction. Patients were evaluated in terms of range of motion (ROM) values; Lysholm, Cincinati and Tegner activity scales; laxity testing and complications. Femoral tunnel widening was assessed by computer tomography scans. Early postoperative and last followup radiographs were compared.Results:
Fifty one patients were evaluated with mean followup of 29 months (range 25–34 months). Mean age at the surgery was 26.5 ± 7.2 years. Lysholm, Cincinati and Tegner activity scales were significantly higher from preoperative scores (Lysholm scores: Preoperative: 51.4 ± 17.2, postoperative: 88.6 ± 7.7 [P < 0.001]; Tegner activity scores: Preoperative 3.3 ± 1.38, postoperative: 5.3 ± 1.6 [P < 0.001]; Cincinati scores: Preoperative: 44.3 ± 17, postoperative: 81.3 ± 13.9 [P < 0.001]). The mean femoral tunnel diameter increased significantly from 9.94 ± 0.79 mm postoperatively to 10.79 ± 0.95 mm (P < 0.05). The mean ROM deficit (involved vs. contra knee) was −7.2 ± 16 (P < 0.001). There was no significant difference for knee score, ROM deficits (<30 years: −7.3 ± 15 and >30 years −7.06 ± 19) and femoral tunnel enlargement (<30 years: 0.83 ± 0.52 and >30 years 0.87 ± 0.43) of the patients with below and above 30 year. There was no significant difference for knee scores and femoral tunnel enlargement between patients with meniscal injuries and don’t have meniscus lesions.Conclusion:
The AperFix system gives satisfactory clinical and radiological results with low complication rate. However, long term clinical and radiological results are needed to decide the ideal anterior cruciate ligament reconstruction method. 相似文献20.

IntroductionThe T-14 questionnaire is a validated patient reported outcome measure (PROM) used to assess the value of paediatric tonsillectomy from the patient’s perspective. Tonsillectomy is a procedure under threat. As such, this study aimed to provide further evidence supporting the role of tonsillectomy in the management of recurrent tonsillitis and obstructive sleep apnoea.MethodsA prospective uncontrolled observational study was undertaken examining 54 paediatric patients undergoing tonsillectomy at our institution. Parents of children having surgery were invited to complete a T-14 questionnaire preoperatively as well as at three and six months postoperatively.ResultsThe questionnaire was completed for 52 of the 54 patients preoperatively as well as at 3 and 6 months postoperatively (96% response rate). The mean difference between the preoperative and six-month T-14 score was 31.8 (p<0.0001). T-14 scores at three months were also significantly improved compared with those taken preoperatively (mean difference: 29.9, p<0.0001).ConclusionsThis is the first study in the literature to assess T-14 questionnaires at three and six months following paediatric tonsillectomy, providing evidence of the early benefit on PROMs. Tonsillectomy is the most common surgical procedure performed in the UK, and it is regarded highly by patients and otolaryngologists alike. This study provides significant evidence that tonsillectomy improves PROMs, thereby demonstrating its ongoing clinical value as a funded National Health Service procedure. 相似文献
