Viscosuppplementation with intra-articular hyaluronic acid (hyaluronan [HA]) is a relatively new option for improving pain and articular function in patients with symptomatic knee osteoarthritis. An open multicenter study was performed in 365 patients with definite and symptomatic knee osteoarthritis from seven Latin American countries. Five doses of HA were administered once a week. The parameters studied were pain (six items), stiffness (two items) and functional capacity (17 items). The parameters were evaluated 1 week after the corresponding injection. Statistical differences were found when basal determinations of the three parameters were compared with the results of the first and fourth administration (p < 0.05). Intra-articular HA administration was well tolerated. Treatment-related nonserious adverse events were registered in 2.5% of administrations. Based on the results obtained, HA is a useful and well-tolerated symptomatic treatment for knee osteoarthritis with a rapid onset of action.
