Patient-Reported Outcomes following Arthroscopic Triangular Fibrocartilage Complex Repair.

 Triangular fibrocartilage complex (TFCC) injury is a common cause of ulnar-sided wrist pain, which may lead to serious physical impairments. Arthroscopic repair has benefits such as less soft tissue damage, greater surgical accuracy, and may lead to faster recovery than open repair.  The purpose of this study was to determine the functional outcome of patients with symptomatic TFCC injuries treated with arthroscopic debridement or repair.  A retrospective study of all consecutive patients with a TFCC injury treated arthroscopically was conducted. The primary outcome was the patient-rated wrist evaluation (PRWE) score. Secondary outcomes were, pain, operative findings, complications, and additional treatment.  A total of 51 patients with a median follow-up of 16.5 months (interquartile range [IQR]: 13-25) were included. Injuries were treated with TFCC debridement (  = 25), TFCC ligament to capsule suturing (  = 10), TFCC debridement and ligament to capsule suturing (  = 7), TFCC debridement and synovectomy (  = 5), and TFCC foveal reinsertion with a suture anchor (  = 4). The median PRWE was 19.5 (IQR: 6-49). Complications occurred in three patients and in nine patients additional surgery was performed.  Arthroscopic treatment of TFCC lesions leads to satisfactory functional outcomes.  This is a Level IV study.
