Unicompartmental knee arthroplasty (UKA) is an ideal surgical approach in treatment of end-stage knee osteoarthritis (KOA), however, indications of UKA have been controversial, and the radiographic and symptomatic patellofemoral osteoarthritis (PFOA) are often considered as a contraindication of medial UKA. 337 fixed bearing UKAs were retrospectively recruited in our joint center between January 1, 2011 and June 30, 2020. There were 105 patients accompanied by PFOA and 232 patients have normal PF joint. International Cartilage Repair Society (ICRS) system was introduced to quantify the degeneration degree of PF joint. Oxford Knee Score (OKS), Forgotten Joint Score (FJS), Kellgren-Lawrence (K-L) classifying system and visual analogue scale (VAS) were adopted to evaluate outcomes between with and without PFOA. There was no significant difference of age, BMI, gender, OKS, FJS and other variables between PFOA and Non-PFOA group. After more than 5 years follow-up, UKA patients with or without PFOA could all achieve a satisfactory improvement of OKS, VAS and FJS score. ROM of the replaced knee increased from preoperative 110° to 130°. 74.3% (78/105) and 75.0% (174/232) patients have no change of K-L grade in PFOA and Non-PFOA group, OKS, FJS, VAS score and ROM were also comparable in all patients and no significant outcomes difference were found between two group. The presence of patellofemoral joint osteoarthritis and anterior knee pain should not be considered to be contraindications to medial fixed-bearing UKA. 相似文献

There has been a resurgence of interest in unicompartmental knee arthroplasty (UKA) for treatment of medial unicompartmental knee osteoarthritis (OA). Improved prosthetic design, minimally invasive surgical techniques, and strict patient selection criteria have resulted in improved survivorship and functional outcomes. A review of orthopedic literature was conducted regarding the advantages of UKA versus total knee arthroplasty (TKA), UKA indications, survivorship, conversion of UKA to TKA, rehabilitation, and outcomes. The UKA appears to be a viable option for patients with knee medial compartment OA, including younger and active patients. Survivorship rates of 94% to 97% at 10 years have been reported. 相似文献

Unicompartmental knee arthroplasty (UKA) is one of the commonly used surgical methods for unicompartmental osteoarthritis in recent years. Although the prognosis of the operated knee has been widely studied, there are relatively little data on the natural history of the contralateral knee after unilateral replacement. The aim of this study was to explore the incidence and risk factors of consequential knee arthroplasty in patients with bilateral knee osteoarthritis (KOA) after receiving primary unilateral UKA, so as to provide a theoretical basis for making a more comprehensive treatment strategy for patients with KOA.We conducted a retrospective study and enrolled patients with bilateral KOA received unilateral UKA from June 2015 to December 2019 in the third department of joint orthopedics, the third hospital of Hebei Medical University. The patients were divided into replacement group and non-replacement group according to whether the contralateral knee joint received knee arthroplasty. Information about treatment of contralateral knee joint was collected from medical records to determine the incidence. Univariate analysis and multivariate logistic regression analysis were performed to identify the independent risk factors.A total of 502 patients were enrolled in this study. The incidence of contralateral knee arthroplasty was 38.64%. In the univariate analysis, vertical angle of mechanical axis, knee joint''s internal and external joint space, Kellgren–Lawrence (K-L) classification, femoral tibial angle were the significant risk factors for contralateral knee arthroplasty. In the multivariate model, only vertical angle of mechanical axis ≥3.03° (odds ratio [OR] 4.36, 95% confidence interval [CI], 2.47–9.11), K-L classification grades 3 and 4 (OR 2.46,3.72; 95%CI, 1.31–4.25, 1.98–6.87), and femoral tibial angle ≥187.32° (OR 6.32, 95%, 2.23–18.87) remained associated with the occurrence of knee arthroplasty.About a quarter of patients with bilateral KOA received unilateral UKA will receive contralateral knee arthroplasty. Higher K-L classification, femoral tibial angle, and mechanical axis vertical angle are identified risk factors. 相似文献

In a prospective clinical trial, the German short musculoskeletal function assessment (SMFA-D), the short form (SF)-36, and the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) were evaluated in 63 patients with primary osteoarthritis undergoing total knee arthroplasty. All instruments were sensitive to change, demonstrating the effect of total knee arthroplasty at 1-year follow-up. The SMFA-D effect sizes in comparable scales were bigger than in the SF-36 and similar to those of the WOMAC. Significant correlations of the SMFA-D indices with the SF-36 and WOMAC scales preoperatively could be shown. After 1-year follow-up, all correlations between the SMFA-D indices and SF-36 scales were significant. In other comparison, only the correlation between the SMFA-D function index and the WOMAC function scales remained significant. The correlation of the SMFA-D function index with external validation criteria was higher than that using the other instruments. We recommend the SMFA-D for assessing change in functional status of patients with primary osteoarthritis of the knee following arthroplasty. 相似文献

AbstractObjectives: This study retrospectively investigated the mid-term outcome of Legacy constrained condylar knee (LCCK) prosthesis in patients with rheumatoid arthritis (RA) having severe varus/valgus deformity, instability, and/or bone loss.Methods: Between January 2000 and December 2015, LCCK prostheses had been performed in 32 knees of 25 patients with RA, and 23 knees of 17 patients of the postoperative follow-up minimum 2 years were analyzed in this study (Primary: 14 knees, Revision: 9 knees). The average of follow-up duration was 6.9?±?2.7 years, all were female, and the average of age and RA duration at the surgery was 59.0?±?9.5 years and 26.6?±?13.5 years, respectively. Clinical result was analyzed by Knee Society Score (KSS) knee and function at preoperative time and final visit. Imaging outcome was investigated by femoral tibial angle (FTA), four component alignment angles, and radiolucent line at pre-/postoperative time.Results: KSS knee/function scores and radiographic FTAs were improved after operation. Radiolucent lines around components were seen in 17 knees (73.9%), of which only one knee (4.3%) has shown aseptic loosening. The seven-year Kaplan-Meier survivorship analysis resulted in 91.7%.Conclusion: LCCK prosthesis in RA patients was achieved to the excellent mid-term clinical and radiographic result. 相似文献

Background:Unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) are widely used for the treatment of medial unicompartmental knee osteoarthritis (OA). However, the best approach remains controversial. This study aimed to present a systematic review and a meta-analysis to directly compare the clinical outcomes between HTO and UKA. We hypothesized that the clinical outcomes after UKA and HTO would be similar.Methods:Electronic databases (Web of Science, PubMed, Embase, CENTRAL, and Biosis Preview) were searched for related studies published before November 30, 2021. Retrospective and prospective studies that directly compared the postoperative outcomes between UKA and HTO were included. Odds ratio (ORs) and 95% confidence interval (CIs) for complications, revision to total knee arthroplasty (TKA), and weighted mean difference (MD) and 95% CIs in range of motion (ROM), pain, walking speed and function score were evaluated. Two reviewers independently assessed the quality of the studies. Subgroup and sensitivity analyses were performed to explore the heterogeneity.Results:Twenty-three retrospective and 6 prospective studies were included. A total of 3004 patients (3084 knees) were evaluated for comparison. Complications (OR, 4.88, 95% CI: 2.92–6.86) were significantly greater in the HTO group than in the UKA group. Postoperative function scores including Lysholm score (MD, −2.78, 95% CI: −5.37 to −0.18) and Hospital for Special Surgery (HSS) score (MD, −2.80, 95% CI: −5.39 to −0.20) were significantly lower in the HTO group than the UKA group. The postoperative ROM was similar between HTO and mobile-bearing UKA (MD, −3.78, 95% CI: −15.78 to 8.22). However, no significant differences were observed between the HTO and UKA group in terms of postoperative pain, walking speed, and revision to TKA.Conclusions:UKA is superior to HTO in minimizing complications and enhancing postoperative function scores. Mobile-bearing UKA has a similar ROM compared with HTO. Both HTO and UKA provide satisfactory clinical outcomes in terms of walking speed, relieving pain, and revision to TKA. UKA appears to be more suitable for the elderly, and both mobile-bearing UKA and HTO are viable surgical options for younger active individuals. 相似文献

Aim of the workTo study the differences between unilateral and bilateral knee osteoarthritis (KOA) patients in relation to the Western Ontario McMaster Universities Osteoarthritis Index (WOMAC), C-reactive protein (CRP) and radiological assessment.Patients and methodsThe study included 80 primary KOA patients subgrouped into those with unilateral or bilateral condition according to the X-ray. WOMAC scale and body mass index (BMI), waist (WC) and thigh (TC) circumferences were measured. The CRP and lipid profile were evaluated and plain X-ray knees assessed by Kellgren and Lawerence (KL) grade.ResultsPatients mean age was 50 ± 9.8 years, disease duration 4 ± 3 years and were 61 females and 19 males. Mean BMI was 32 ± 6.6, WC 96 ± 20 cm, TC 56 ± 11.5 cm, WOMAC 43 ± 14 and KL grade 2 ± 0.9. Unilateral knee was detected in 28 (35%) and was bilateral in 52 (65%) patients. Highest pain was detected in female patients on using stairs and was significant on weight-bearing (p = 0.004), but going downstairs and the KL grade were significantly more in males (p = 0.004 and p = 0.03 respectively). The WOMAC pain subscale items and KL grading were significantly increased in patients with bilateral KOA. The WOMAC significantly correlated with the BMI, WC, TC, lipid profile and KL grade (p < 0.0001 for all). On regression, only the disease duration and cholesterol levels were predictors of WOMAC score (β = 0.2, p = 0.04 and β = 0.29, p = 0.03 respectively).ConclusionsPain on weight bearing in females and bending activities especially going downstairs (in males) appears early with primary KOA. Bilateral involvement is more painful with more radiographic severity. 相似文献

Aim of the workThe present study was conducted to identify the frequency of neuropathic pain (NP) and its relationship with functional status and radiological severity in a series of Egyptian patients with primary knee osteoarthritis (OA).Patients and methodsThe study included 165 patients with primary KOA. Visual analogue scale (VAS)-pain was estimated and the Western Ontario and McMaster (WOMAC) Universities osteoarthritis index was used for assessment of pain, stiffness and physical function, Douleur Neuropathique in 4 questions (DN4) questionnaire was used to assess NP and Kellgren-Lawrence (KL) radiological grading was used to assess OA severity.ResultsThe mean age of the patients was 53.08 ± 6.95 years, were 144 females and 21 males, 23 were employed, body mass index was 24.87 ± 1.91 and total WOMAC was 44.24 ± 16.52. The mean DN4 score was 2.81 ± 1.27. 29 (17.6%) patients had NP. The mean symptom duration was significantly longer in patients with NP (50.9 ± 14.58 months) compared to those without (36.53 ± 25.25 months) (p = 0.008). The VAS-pain and WOMAC score were significantly increased in patients with NP compared to those without (p < 0.001) while the KL was comparable. The DN4 questionnaire significantly correlated with VAS-pain at rest (r = 0.56, p = 0.002); and with WOMAC pain subscale (r = 0.38, p = 0.043).ConclusionA relevant proportion of KOA patients have NP and is remarkably related to the disease duration. Functional capacity is adversely affected in these patients. However, no relation was found between DN4 questionnaire and the radiological severity. Once detected, suitable treatment options for NP should be included in the management of primary KOA. 相似文献
