title: The Outcomes of Arthroscopic Repair Versus Debridement for Chronic Unstable Triangular Fibrocartilage Complex Tears in Patients Undergoing Ulnar-Shortening Osteotomy.
abstract: OBJECTIVE
  The aim of this study was to compare the results of arthroscopic peripheral repair (AR) and arthroscopic debridement (AD) for the treatment of chronic unstable triangular fibrocartilage complex (TFCC) tears in ulnar-positive patients undergoing ulnar-shortening osteotomy (USO).
  
  
  METHODS
  A total of 31 patients who underwent arthroscopic treatments combined with USO for unstable TFCC tears and were followed-up at a minimum of 24 months were included in this retrospective cohort study. Fifteen patients were treated with AR, and 16 patients were treated with AD while at the same time undergoing a USO. Outcome measures included wrist range of motion, grip strength, Disabilities of the Arm, Shoulder, and Hand (DASH) and Patient-Rated Wrist Evaluation (PRWE) scores, and overall outcomes according to the modified Mayo wrist scoring system. In addition, a stress test to assess distal radioulnar joint (DRUJ) stability was performed before and after surgery to compare the 2 cohorts.
  
  
  RESULTS
  Both respective cohorts showed significant improvements in grip strength and subjective scores at the final follow-up. Grip strength, DASH, and PRWE scores were better in the AR group than in the AD group. The recovery rate from DRUJ instability observed during the preoperative examination was superior in the AR group.
  
  
  CONCLUSIONS
  Both AD and AR of the TFCC combined with USO are reliable procedures with satisfactory clinical outcomes for unstable TFCC tears in ulnar-positive patients. However, AR of the TFCC is suggested if DRUJ stability is concomitantly compromised.
