Double-blind clinical evaluation of intra-articular glucosamine in outpatients with gonarthrosis.

Abstract

Fifty-four outpatients with gonarthrosis participated in a double-blind clinical test with the aim of evaluating the efficacy and tolerance of intra-articular glucosamine in comparison with a 0.9% NaCl placebo. Each patient had one intra-articular injection per week for five consecutive weeks. Pain, active and passive mobility of the joint, swelling, and generalized and local intolerance symptoms were recorded before beginning the treatment, and four weeks after the last injection. glucosamine reduced pain to a significantly greater extent than did placebo, and resulted in significantly more pain-free patients. The angle of joint flexion substantially increased after glucosamine treatment. Active mobility increased with both treatments, with a more favorable trend after glucosamine administration. Knee swelling did not decrease significantly after glucosamine, whereas it worsened (although no significantly) after placebo. There were no local or general intolerance symptoms during and after treatment. Glucosamine administration was able to accelerate the recovery of arthrosic patients, with no resulting side effects, and to partially restore articular function. In addition, the clinical recovery did not fade after treatment ended, but lasted for the following month, at least. These features are a definite improvement over antirheumatic drugs, the major drawbacks of which are action of short duration and side effects. Glucosamine therapy therefore deserves a selected place in the management of osteoarthrosis.
