Condition osteoarthritis, knee
Treatment injection of hyaluronan or saline
Phase phase 4
Sponsor Glostrup University Hospital, Copenhagen
Start date May 1999
End date November 2001
Trial size 251 participants
Trial identifier NCT00144820, KA 99005gs


251 consecutive patients with knee arthrosis were randomized to one of three interventions: Four weekly injections of 2 ml isotonic saline (placebo), 2 ml sodium hyaluronate (hyaluronan) or 20 ml isotonic saline (excessive saline).

They all suffered from clinically and radiologically verified arthrosis of the knee with daily pain that did not respond to treatment with analgetics.

Results were evaluated at weeks 1,2,3,4,8,12,16 and 26. Biochemical markers for bone and cartilage degradation were measured in urine/blood.
