Abstract
Arthroscopic surgery is a common intervention for osteoarthritis of the knee. However, the benefits from such an intervention are not clear. The purpose of the study was to perform a questionnaire survey of orthopaedic surgeons of Wales to analyse the practice of arthroscopy for osteoarthritic knee.
Over a three-month period, a postal survey was conducted of all hospital orthopaedic consultants in Wales. Of a total of 62 questions sent we received a reply of 37. 31 surgeons perform arthroscopic lavage or debride-ment. 4 surgeons perform arthroscopic surgery for symptomatic meniscal tear only. There was no defined protocol regarding the management. Early OA was the commonest indication (18). Arthroscopic lavage (17) was equally popular to lavage and debridement (16). 6 respondents like to perform the surgery themselves while the majority would allow a middle grade surgeon to operate with or without supervision. 26 surgeons felt that the results of the procedure are unpredictable, but still continued to perform it. Only 6 surgeons felt a continued relevance of the procedure.
Arthroscopic surgery is a commonly performed symptomatic treatment for arthritic knee. It bears a significant financial commitment. 266 arthroscopic knee surgery were performed annually in a district general hospital, of whom 115 were arthroscopic washout. Average cost of each operation is £1000. The physiological basis for arthroscopic washout is not clear. A majority of the Welsh surgeons have reservations about this procedure. In spite of evidence of limited usefulness, it is still performed widely.
