Arthroscopic management of temporomandibular joint disc perforations and associated advanced chondromalacia by discoplasty and abrasion arthroplasty: preliminary results.

This article describes the arthroscopic surgical treatment of disc perforations by discoplasty to mobilize the disc and reduce joint friction. Grade IV chondromalacia with exposed bone was treated by abrasion arthroplasty with the goal of resurfacing the bone with fibrocartilage. Preliminary data on the results of these procedures are presented.
