Outcome Following Hylan F- 20 (Synvisc) + Corticosteroid Injections for the Treatment of Osteoarthritis of the Knee

• Status: Completed
• Trial end date: 2008-02-01
• Target enrollment: 0
• Participant gender: All

Summary

The goal of viscosupplementation is to replenish synovial fluid, which will improve patient symptoms and mobility. Viscosupplementation of the knee with hyaluronic acid injections has been shown to improve symptoms in patients with osteoarthritis. Recent studies have shown that this improvement may be highly variable based on the time from treatment, especially in the first 12 weeks following treatment. The purpose of this study is to document the outcomes following a treatment protocol in which corticosteroid is used in addition to the initial Synvisc injection in the series of three injections.

Criteria

Inclusion Criteria:

• Men or women aged 18 to 80 years

• with a diagnosis of osteoarthritis of the knee. Diagnosis will be based on radiographic examination (Kellgren-Lawrence 2 or 3) or by previous arthroscopic diagnosis.

Surgical treatment for osteoarthritis will be limited to arthroscopic surgeries that include removal of loose bodies, resection of unstable meniscus tears and loose or unstable chondral flaps, removal of osteophytes if they limit extension, and lysis of adhesions. These types of treatments may provide symptomatic relief by increasing joint volume in knees with osteoarthritis and relieving joint contact pressures.

Exclusion Criteria:

• Patients with grade 4 Kellgren-Lawrence on radiographic examination will be excluded.

• Patients with a prior synovectomy on knee to be injected will be excluded.

• Patients will be excluded if they have rheumatoid disease or any other serious systemic disease, acute synovitis or excessive effusion, allergy to avian products/hyaluronan-based injection components/corticosteroid injection, pregnant, previous arthroscopic surgery within the last 6 months or had a joint infection within the previous 3 months.

• Patients who have undergone a prior synovectomy will not be included.
