ABSTRACT
Objective: To compare improvement after arthroscopic lavage in osteoarthritis of knee joints with conventional treatment.Design: Open Control TrialSetting: Tertiary care hospitalIntervention: Arthroscopic lavage and conservative treatment.Participants: 48 knees of 29 osteoarthritis patients attending orthopaedic OPD from 30th January 2003 to 30th January 2004. Patients who scored < 24 on WOMAC scale were excluded.Main outcomes measured: Functional capacity of knee by WOMAC index at pre treatment 4th, 8th week, 12 week of follow up after treatment. 21 knees in 13 patients received conservative treatment. 24 knees in 16 patients received Arthroscopic lavage with add on the conservative treatment.Results: Both on pain and function scores cases were worse pre treatment as expected because only patients with severer disease were likely to opt for Arthroscopic treatment. However, patients treated arthroscopically did better both clinically and statistically both in respect of function and pain. However, the difference became lesser with time.Conclusions: Cases initially worst than controls did statistically and clinically better in terms of pain and function up to 12th week of follow up without complication. Given the low incremental cost and simplicity of this day care procedure arthroscopic lavage is a simple useful and safe adjunct to conventional treatment in O.A of knee, which shows a trend to delay the progress of the disease. When is a repetition needed and how effective will it be remain to be answered.
