title: Arthroscopic management of temporomandibular closed lock.
abstract: Sixty-three consecutive patients with painful closed lock involving 83 temporomandibular joints were treated by surgery and followed up for at least 24 months. Prior to surgical treatment all had imaging to demonstrate that the cause of their painful jaw locking was an anterior displaced disc without reduction. All patients had received at least three months non-surgical treatment without response. The arthroscopic surgery consisted of release of adhesions, manipulation and placement of 25 mg hyaluronic acid into the joint space. No significant surgical complications occurred. Postoperative treatment involved physical therapy and stabilization splints. At 24 months after surgery 57 patients (90.5 per cent) had no pain and month opening had improved from preoperative 27.2 +/- 5.4 mm to 44.4 +/- 4.1 mm (p < 0.001). This study shows that arthroscopic surgery with continuing non-surgical therapy is a highly effective treatment for painful closed lock.
