A prospective randomised trial comparing intra-articular Hyalgan injection and arthroscopic washout for knee osteoarthritis.
Thirty-eight patients with symptomatic knee osteoarthritis without mechanical symptoms were randomised after informed consent to receive either a course of intra-articular Hyalgan injections or an arthroscopic washout. The patients were prospectively assessed pre-intervention, 6 weeks, 3 months, 6 months and 1 year using a 10 cm visual analogue pain score, the Knee Society function score and the Lequesne index. There was no significant difference between the two groups at 6 weeks, 3 months, 6 months or 1 year. The use of intra-articular Hyalgan injections in patients with knee osteoarthritis without mechanical symptoms gives results comparable with arthroscopic washout. Hyalgan is an alternative to arthroscopy in this patient group. Further study is needed to confirm these findings and improve patient selection.
