Arthroscopic-Assisted Foveal Reattachment of Triangular Fibrocartilage Complex Tears With Distal Radioulnar Joint Instability: A Comparison of Suture Anchors and Transosseous Sutures.

Abstract

To compare the clinical outcomes of arthroscopically-assisted suture anchor repair and transosseous sutures for repair of foveal triangular fibrocartilage complex tears in patients with distal radioulnar joint (DRUJ) instability. Sixty patients with triangular fibrocartilage complex foveal detachment associated with DRUJ instability were prospectively recruited and randomized into 2 equal groups-the anchor repair group and the transosseous repair group. The primary outcome was DRUJ function after 2 years, which was assessed by the DRUJ evaluating system. The secondary outcomes were grip strength, visual analog scale for pain, Mayo Modified Wrist ScorePatient-Rated Wrist Evaluation score, and the Disabilities of the Arm, Shoulder, and Hand score. There were no significant differences between the groups for any of the outcome measures. Good-to-excellent outcomes (according to the DRUJ evaluation system) were achieved in 27 (90%) patients in the anchor repair group and 26 (86.7%) patients in the transosseous repair group. Fewer complications were observed in the anchor repair group. Both techniques yielded good and comparable outcomes with a lesser incidence of early complications in the anchor repair group.
