A COMPARISON OF SYNVISC AND ARTHROSCOPIC LAVAGE IN THE MANAGEMENT OF OSTEOARTHRITIS OF THE KNEE

4 Rural Way, Ty Coch, Swansea, SA2 9NA

Arthroscopic lavage is commonly used in the management of mild to moderate arthritis of the knee. In the last few years the use of Hyaluronic Acid and its derivatives has become popular in the management of this same group of patients. The study was set up to establish whether Synvisc (HylanGF-20) produced equivalent or improved symptomatic relief when compared to arthroscopic lavage.

A prospective randomised trial. Fifty patients with knee OA were randomly allocated to either the arthroscopic lavage or Synvisc group. All patients were assessed prior to treatment using the WOMAC knee evaluation questionnaire, and further assessments were made at 6 weeks, 3 months, 6 months and one year post treatment.

The Synvisc group showed greater and more consistent improvement in WOMAC scores than the lavage group at all assessments post treatment. The difference between the treatment groups was statistically significant at 6 months (p<0. 05) and at 1 Year (p=0. 0018).

We conclude that a course of Synvisc injections can be administered on an out-patient basis and is a safer, more cost-effective and more reliable treatment for Knee OA compared to arthroscopic lavage.
