Arthroscopic disc repositioning and suturing: a preliminary report.

Eight patients (11 joints) underwent arthroscopic disc repositioning and suturing. Disc displacement was established by physical examination, magnetic resonance imaging (MRI), and diagnostic arthroscopy. Postoperative MRIs were taken at varying intervals between 1 day and 6 months. In all 11 joints, either partial improvement or normal disc position was observed arthroscopically. In 9 of the 11 joints, either partial improvement or normal position was observed on the postoperative MRIs. It is concluded that posterior disc repositioning and suturing is an achievable goal of temporomandibular joint arthroscopy.
