OBJECTIVE: To assess functional change in patients with knee osteoarthritis (OA) after treatment with intra-articular hyaluronic acid (Hylan G-F 20; Synvisc). DESIGN: Prospective case series with 6-month follow-up. SETTING: Outpatient community orthopedic practice. PARTICIPANTS: Eighty-four consecutive patients referred to private orthopedic group with symptoms and radiographic evidence of unilateral or bilateral knee OA who had either failed or could not tolerate the side effects of conservative treatment. Sixty-one patients completed the study. Nineteen patients were lost to follow-up. Four patients withdrew from study due to subsequent knee arthroplasty. INTERVENTION: Three weekly injections of Hylan G-F 20 into one or both (if bilaterally symptomatic) knees (110 knees total). OUTCOME MEASURE: SF-36 Health Survey was completed before treatment and 6 months after treatment. RESULTS: Statistically significant improvement (p < .001) in Physical Functioning, Role-Physical, Bodily Pain, Social Functioning, and Role-Emotional categories on 6-month follow-up survey. Age and percent above ideal body weight were not significant predictors of functional change. CONCLUSION: Efficacy of intra-articular injection of Hylan G-F 20 for knee OA 6 months after injection is demonstrated in several categories of the SF-36, indicating a measurable improvement in overall functioning in these patients. 相似文献

OBJECTIVE: To study the efficacy of hylan G-F 20 in the treatment of osteoarthritis (OA) of the hip joint. DESIGN: Prospective within-group study. SETTING: Musculoskeletal rehabilitation clinic. PARTICIPANTS: Twenty-two patients (25 hips) with hip joint OA who had failed to find pain relief from conservative methods such as physical therapy, exercises, and steroid injections. Demographics included 14 men and 11 women (mean age, 56.4y), 21 of whom had mild to moderate OA and 4 of whom had severe OA of the hips. INTERVENTION: Each hip joint was injected with 2mL of hylan G-F 20 at 2, 3, and 4 weeks and fluoroscopic lavage with 100mL of normal saline at week 1. All patients had standard hip exercise regimen after the injection. MAIN OUTCOME MEASURES: American Academy of Orthopaedic Surgeons (AAOS) Lower Limb Core Scale score and visual numeric pain score. RESULTS: At 1-year follow-up, the AAOS Lower Limb Core Scale score improved from a preinjection mean of 44.2 to a follow-up mean of 86.1 (P<.05). The mean visual numeric pain score improved from a preinjection mean of 8.7 (range, 6.4-10) to a follow-up mean of 2.3 (range, 0-7.2). The overall success rate was 84%. In patients with mild to moderate OA, the mean pain score decreased from a preinjection value of 7.8 to a follow-up value of 1.7. The success rate was 90.5% in that subgroup. In patients with severe OA, the mean pain score decreased from a preinjection value of 9.1 to a follow-up value of 3.8. The success rate was 50% in that subgroup. There were no complications related to the injection. CONCLUSION: Use of hylan G-F 20 injection is a viable option for treatment of mild to moderate OA of the hip joint. 相似文献

The objective of this 12-week, double-masked, randomized, multicenter study was to compare the elastoviscous properties of a high-molecular-weight viscosupplement, hylan G-F 20 (polymer concentration, 0.8%), with those of a lower-molecular-weight hyaluronan (LMW HA) product (polymer concentration, 1%) and to determine the relationship of elastoviscosity to efficacy in the treatment of patients with osteoarthritis (OA) of the knee. Patients had radiographically confirmed primary idiopathic OA of the knee (Larsen grades I to V) with pain despite other treatments. After a 2-week washout period, 70 patients (73 knees) received three 2-mL intra-articular injections of test solution at 1-week intervals. Thirty-eight patients (38 knees) received hylan G-F 20, and 32 patients (35 knees) received LMW HA. During the 12-week follow-up period, the primary outcome measures assessed by patients (using a visual analogue scale) were weight-bearing pain, most painful knee movement, and overall treatment response; the primary outcome measures assessed by study evaluators were weight-bearing pain and overall assessment of treatment. The dynamic elastoviscous properties of the test solutions were measured on an oscillating Couette-type rheometer. Hylan G-F 20 was more elastoviscous than the LMW HA at all frequencies measured (0.001 to 10 Hz). At the final evaluation, patients who received hylan G-F 20 had significantly better results on all primary outcome measures compared with those who received LMW HA. No systemic adverse events were reported. Local adverse events consisted of pain or swelling, noted in 2 of 38 knees injected with hylan G-F 20, and pain, noted in 1 of 35 knees injected with LMW HA (adverse event rates per injection, 1.8% and 0.9%, respectively). The difference in the incidence of adverse events between groups was not statistically significant. The higher-molecular-weight, more elastoviscous hylan G-F 20 had significantly greater pain-relieving effects than did the lower-molecular-weight, less elastoviscous hyaluronan. 相似文献

OBJECTIVE: To assess the difference in efficacy between knee lavage plus the standard hylan G-F 20 (a derivative of hyaluronan) protocol and the standard hylan G-F 20 as per standard usage protocol alone for the treatment of knee osteoarthritis (OA). DESIGN: Nonrandomized prospective study in which patients chose their treatment group. Follow-up averaged 1.1 years. SETTING: Faculty practice of a single physician at a major teaching hospital. PARTICIPANTS: Eighty-one patients with documented knee OA on magnetic resonance imaging. INTERVENTIONS: Group 1 (n=44) received a single-needle lavage 1 week before the standard hylan G-F 20 protocol; group 2 (n=37) received the standard hylan G-F 20 protocol alone. MAIN OUTCOME MEASURES: Pre- and posttreatment scores on the Lysholm-II Questionnaire and a visual analog scale (VAS) were documented for each patient. The Wilcoxon signed-rank test was used for statistical analysis. RESULTS: A successful outcome was noted in 79.5% of group 1 patients and in 54% of group 2 patients (P<.05). CONCLUSIONS: In the management of knee OA, the use of knee lavage before viscosupplementation with hylan G-F 20 yields better results than using hylan G-F 20 alone. The presence of radiologic grade IV knee OA or moderate to severe patellofemoral arthritis are negative prognostic factors. 相似文献

OBJECTIVES: To examine the gait patterns and the sagittal ground reaction forces (GRFs) in persons with knee osteoarthritis (OA) after intra-articular injection of hyaluronate and to investigate the duration of its treatment effectiveness. DESIGN: Case-comparison study. SETTING: Gait laboratory in a tertiary care center. PARTICIPANTS: Fifteen subjects (30 knees) with symptomatic knee OA (stage I or II, according to the Ahlb?ck grading system), and 15 age-, mass-, and gender-matched non-OA control subjects (30 knees). INTERVENTION: After initial gait analysis, the group with knee OA received 5 weekly intra-articular injections of hyaluronate to bilateral knees. Gait analysis was performed again for the group with knee OA after the completion of hyaluronate injections. MAIN OUTCOME MEASURES: Forceplate sagittal GRFs and gait parameters of velocity, cadence, step length, and stride time. RESULTS: The distinctive 2-peak force vector GRF was lost in persons with knee OA. The first peak rise time was significantly delayed (P<.05). The group with knee OA also revealed slower walking velocity and cadence, as well as longer stride time, than the control group (P<.05). The distinctive 2-peak force vector GRF diagram could be recovered in patients with knee OA after the completion of hyaluronate injections. CONCLUSIONS: Gait patterns and GRFs improved significantly after intra-articular knee injection of hyaluronate in persons with Ahlb?ck stages I and II knee OA. The clinical treatment effect was immediate and may last for 6 months or more. 相似文献

OBJECTIVE: To investigate the local effects of hylan G-F 20 on locally administered corticosteroid-induced experimental Achilles' tendonitis. DESIGN: Before-after trial. SETTING: Institutional practice. ANIMALS: Convenience sample of 18 male Wistar white rats (weight range, 322-375 g). INTERVENTIONS: After performing Achilles' degeneration with local corticosteroid injections, the rats were divided into 4 groups. The right Achilles' tendon of the rats served as the hylan injection group and the left tendon as the control group, which was injected with saline at 5-day intervals. The tendons and paratenons were excised at the end of 60 or 75 days and evaluated histopathologically and statistically. MAIN OUTCOME MEASURE: Histopathologic changes, including staining affinity, nuclear appearance, fibrillar appearance for tendon and thickness, occurrence of fibrosis and edema, capillary changes, and inflammation for paratenon, were assessed according to a semiquantitative scoring system. The Mann-Whitney U test was used for statistical analysis, with a P value of.05 or less considered statistically significant. RESULTS: Semiquantitative scoring of histopathologic changes showed that histologic appearances differed between the hylan and saline groups and between 2 hylan groups. Hylan-injected tendons and paratenons demonstrated significantly lower scores, especially after 75 days. CONCLUSIONS: Hylan G-F 20 has a promising curative effect on the tendon and paratenon and can be used in Achilles' tendonitis. This finding should be supported by biomechanical and biochemical studies. 相似文献

A study was conducted to determine the accuracy of intra-articular injections for osteoarthritis (OA) of the trapeziometacarpal joint (TMCJ). Over a period of 12 months intra-articular injections on 60 TMCJs (12 males and 48 females) were carried out. All the injections were performed in the operating theatre. The operator inserted the needle into the position clinically assessed to be the TMCJ and the position was assessed using biplanar fluoroscopy. In 42% of cases, the needle was incorrectly placed and its position had to be adjusted, using fluoroscopy, to ensure correct intra-articular placement. Entry into an osteoarthritic TMCJ with a blind passage of the needle is not straightforward. A proper injection technique must be employed to enter the correct joint. Using an image intensifier greatly facilitates accurate needle placement. 相似文献

ObjectivePrevious studies have shown that a customized biomechanical therapy can improve symptoms of knee osteoarthritis. These studies were small and did not compare the improvements across gender, age, BMI or initial severity of knee osteoarthritis. The purpose of this study was to evaluate the effect of new biomechanical therapy on the pain, function and quality of life of patients with medial compartment knee osteoarthritis.MethodsSix hundred and fifty-four patients with medial compartment knee osteoarthritis were examined before and after 12 weeks of a personalized biomechanical therapy (AposTherapy). Patients were evaluated using the Western Ontario and McMaster Osteoarthritis (WOMAC) Index and SF-36 Health Survey.ResultsAfter 12 weeks of treatment, the WOMAC-pain and WOMAC-function subscales were significantly lower compared to baseline (both P ≤ 0.001). All eight categories of the SF-36 health survey significantly improved after treatment (all P ≤ 0.001). Females and younger patients showed greater improvements with therapy.ConclusionsTwelve weeks of a customized biomechanical therapy (AposTherapy) improved symptoms of patients with medial compartment knee osteoarthritis. We recommend that this therapy will be integrated in the management of knee osteoarthritis. 相似文献

ABSTRACTIntroduction: Knee osteoarthritis (KOA) is a mechanically induced, cytokine and enzyme-mediated disorder involving all the joint tissue of the knee. Rebuilding a physiological-homeostatic network at the tissue level following knee organ failure, such as in severe KOA, is a daunting task with therapeutic targets encompassing the articular cartilage, synovium and subchondral bone. Intraarticular infiltration of plasma rich in growth factors (PRP) has emerged as a promising symptomatic approach, although it is insufficient to reach the subchondral bone.Areas covered: This review addresses current molecular and cellular data in joint homeostasis and osteoarthritis pathophysiology. In particular, it focuses on changes that subchondral bone undergoes in knee osteoarthritis and evaluates recent observations on the crosstalk among articular cartilage, subchondral bone and synovial membrane. In addition, we review some mechanistic aspects that have been proposed and provide the rationale for using PRP intraosseously in KOA.Expert opinion: The knee joint is a paradigm of autonomy and connectedness of its anatomical structures and tissues from which it is made. We propose an innovative approach to the treatment of severe knee osteoarthritis consisting of a combination of intraarticular and intraosseous infiltrations of PRP, which might offer a new therapeutic tool in KOA therapy. 相似文献

PURPOSE: To assess sonographic changes in Baker's cysts (BCs) of patients with knee osteoarthritis after a single intra-articular corticosteroid injection. METHODS: Thirty patients with knee osteoarthritis complicated with a symptomatic BC received a single intra-articular injection of 40 mg triamcinolone acetonide. Knee pain, swelling, and range of motion were evaluated. BC area and thickness of the cyst wall were measured with sonography before and 4 weeks after local treatment. RESULTS: A significant improvement in knee pain, swelling, and range of motion after corticosteroid injection was accompanied by a decrease in size of the BCs as well as in thickness of the cyst wall as measured by sonography. Moreover, the reduction of BC area on sagittal scans after treatment was significantly correlated with the improvement in range of motion. CONCLUSIONS: In this series of osteoarthritis patients, injection of corticosteroids inside the knee joint accounted for a reduction in BC dimensions as well as cyst wall thickness. Sonography can be used not only for the diagnosis of BCs but also to monitor response to therapy. 相似文献
