Original Research
This study was conducted to determine the efficacy and safety of three once-weekly injections of intra-articular Hylan G-F 20 in patients with chronic knee osteoarthritis over 26 weeks. It was hypothesized that Hylan G-F 20 would provide significant pain relief with no increased safety risk compared with IA saline (placebo).
Original Research
Intra-articular injection of hyaluronic acid (HA) for knee osteoarthritis (OA) effectively reduces pain and delays total knee replacement (TKR) surgery; however, little is known about relative differences in clinical and cost outcomes among different HA products. In this study, the authors conclude that analysis of administrative claims data provides real-world evidence that meaningful differences exist among some HA products in disease-specific cost and time to knee replacement surgery.
