This retrospective review evaluates the effectiveness and tolerability of
hylan G-F 20 for relief of
pain due to
knee osteoarthritis in a large orthopedic practice over a 5-year period. Prospectively collected data from patients who initiated intra-articular
hylan G-F 20 (3 weekly
injections) for
osteoarthritis knee pain treatment were analyzed. Efficacy variables included physician visual analogue scale (VAS: 100 mm), and patient rating of
pain, mobility, and amount of
pain medication taken
after treatment. Patients (n=1047; 1489 knees) were an average age of 65.3 years, 60% female, and 71% had radiologic
osteoarthritis grade IV. Mean VAS scores significantly improved with
hylan G-F 20 compared to baseline at all time points (P<.0001). Most knees (62%-89%) responded positively with
hylan G-F 20.
Pain and mobility improved and less
pain medication was needed after
therapy. The incidences of local adverse events were 5.2% per patient and 1.2% per injection; most local adverse events were mild or moderate, with severe local events in 0.3% of
injections. Our clinical experience shows that
hylan G-F 20 effectively relieves
osteoarthritis knee pain (as indicated) and reduces
pain medication needed for up to 6 months with a low incidence of local adverse events.
