    Functional improvement with hylan G-F 20 in patients with knee osteoarthritis. Brander Victoria A,Stadler Teresa S The Physician and sportsmedicine A systematic review of randomized, controlled, prospective clinical studies is described (8 trials; N = 1674 patients), with > 100 patients in each, which evaluated functional outcomes with hylan G-F 20 in secondary analyses. Hylan G-F 20 significantly improved Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) physical function versus appropriate/conventional care or corticosteroid, it significantly improved loss of activity versus saline, and it had similar functional improvements compared with progressive knee exercises or nonsteroidal anti-inflammatory drugs. Functional improvements with hylan G-F 20 also improved with pain relief. Hylan G-F 20 should be considered as part of a multimodal arthritis treatment regimen that focuses on improving function. 10.3810/psm.2009.10.1728
    Evaluating the use of intra-articular injections as a treatment for painful hip osteoarthritis: a randomized, double-blind, multicenter, parallel-group study comparing a single 6-mL injection of hylan G-F 20 with saline. Brander V,Skrepnik N,Petrella R J,Jiang G-L,Accomando B,Vardanyan A Osteoarthritis and cartilage OBJECTIVE:Hip osteoarthritis (OA) is difficult to treat. Steroid injections reduce pain with short duration. With widespread adoption of office-based, image-guided injections, hyaluronic acid is a potentially relevant therapy. In the largest clinical trial to-date, we compared safety/efficacy of a single, 6-mL image-guided injection of hylan G-F 20 to saline in painful hip OA. METHOD:357 patients were enrolled in a multicenter, double-blind, randomized saline placebo- controlled trial. Subjects were ≥35 years of age, with painful (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC]-A1:5.0-8.0; numeric rating scale [NRS]: 0-10) mild-to-moderate hip OA (Kellgren-Lawrence grade II/III) and minimal contralateral hip pain (WOMAC-A1 < 4). Outcome measures included "pain on walking" (WOMAC-A1 and -A), Patient Global Self-Assessment (PTGA), WOMAC-A1 responder rate (+≥2 points on NRS), and adverse events (AEs) over 26 weeks. RESULTS:357 patients (hylan G-F 20 single:182; saline:175) were enrolled. Both groups demonstrated significant pain improvement from baseline over 26 weeks (P < 0.0001); saline-induced pain reduction was a remarkable 35%. WOMAC-A and PTGA scores also significantly improved (P < 0.0001). No statistically significant difference was observed between groups in WOMAC-A1 scores (hylan G-F 20 single:-2.19 ± 0.16; saline:-2.26 ± 0.17) or WOMAC-A1 responders (41-52%). Treatment-related AE rates at target hip were similar (hylan G-F 20 single:23 patients [12.8%]; saline:12 [7.0%]). Posthoc analysis found, despite protocol requirements, many patients had psychological (31%) or potential neuropathic pain (27.5%) conditions. CONCLUSION:A single 6-mL hylan G-F 20 injection or saline for painful hip OA resulted in similar, statistically significant/clinically relevant pain and function improvements up to 6 months following injection; no differences between hylan G-F 20 and saline placebo were observed. 10.1016/j.joca.2018.08.018
    Single, intra-articular treatment with 6 ml hylan G-F 20 in patients with symptomatic primary osteoarthritis of the knee: a randomised, multicentre, double-blind, placebo controlled trial. Chevalier X,Jerosch J,Goupille P,van Dijk N,Luyten F P,Scott D L,Bailleul F,Pavelka K Annals of the rheumatic diseases OBJECTIVES:The primary objective was to compare a single, 6 ml, intra-articular injection of hylan G-F 20 with placebo in patients with symptomatic knee osteoarthritis. The safety of a repeat injection of hylan G-F 20 was also assessed. METHODS:Patients with primary osteoarthritis knee pain were randomly assigned to arthrocentesis plus a 6 ml intra-articular injection of either hylan G-F 20 or placebo in a prospective, double-blind (one injector/one blinded observer) study. RESULTS:were evaluated at 4, 8, 12, 18 and 26 weeks post-injection. The primary outcome criterion was change from baseline over 26 weeks in Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index A pain. Secondary outcome measures included WOMAC A1 and C, patient global assessment (PGA) and clinical observer global assessment (COGA) and Outcome Measures in Rheumatology, Osteoarthritis Research Society International responder rates. A 4-week, open, repeat treatment phase evaluated safety only. Results: A total of 253 patients (Kellgren-Lawrence grade II or III) was randomly assigned. Patients receiving hylan G-F 20 experienced statistically significantly greater improvements in WOMAC A pain scores (-0.15, SE 0.076, p = 0.047), and several of the secondary outcome measures (WOMAC A1, PGA and COGA), than patients receiving placebo. There was no difference between the safety results of the two groups. No increased risk of local adverse events was observed in the open, repeat treatment phase. CONCLUSIONS:This placebo-controlled study demonstrated that, in patients with knee osteoarthritis, a single 6 ml intra-articular injection of hylan G-F 20 is safe and effective in providing statistically significant, clinically relevant pain relief over 26 weeks, with a modest difference versus placebo. 10.1136/ard.2008.094623
