AB  - OBJECTIVE: To assess prospectively the efficacy and tolerability of hylan G-F 20 (HG-F 20; Synvisc) and intraarticular triamcinolone hexacetonide (TH; Aristospan) for treatment of osteoarthritis (OA) knee pain in a 26 week, randomized, multicenter, evaluator-blind study. METHODS: Patients with OA were treated with typical regimens of HG-F 20 (n = 113) and TH (n = 102). Primary assessments were the WOMAC question A1 (pain walking on a flat surface), and a 100 mm visual analog scale (VAS) for patient and investigator overall assessments. Total WOMAC and WOMAC domain C (function) scores were also assessed. The intent-to-treat population was analyzed using a last-observation carried forward approach. RESULTS: Maximum pain relief occurred at 1-2 weeks for TH and at Week 12 for HG-F 20. At Weeks 12 and 26, HG-F 20 was significantly better than TH for the WOMAC question A1 responses (p = 0.0071 and p = 0.0129, respectively), and patient VAS (p < 0.0001 and p < 0.0001) and investigator VAS (p < 0.0300 and p = 0.0004) assessments. Similar significant (p < 0.01) results were observed at Weeks 12 and 26 for total WOMAC and domain C scores. While 15 TH-treated patients discontinued the study due to lack of efficacy, none did so with HG-F 20 treatment (p < 0.01). Both agents were well tolerated with similar adverse event profiles. CONCLUSION: Viscosupplementation with HG-F 20 resulted in a longer duration of effect than TH with a comparable tolerability profile. These data support the preferential use of HG-F 20 over TH for treatment of chronic OA knee pain.
