Transcutaneous meniscectomy under arthroscopic control.

A technique of arthroscopic excision of a torn meniscus has evolved during two years' experience of therapeutic arthroscopy of the knee joint. The same method is used for both medial and lateral meniscus lesions under full visual control throughout the procedure, with a standard arthroscope inserted centrally through the patellar tendon. The first 18 consecutive patients thus treated have been followed up. Endoscopic operation was complemented by arthrotomy in three; in 15 no other treatment was given. The time in hospital, convalescence, sick leave, and knee function at follow-up were compared in these 15 patients with matched controls treated in the ordinary way by arthrotomy. Knee function did not differ between the groups, whereas all other variables showed better results after arthroscopic excision.
