Background: Little information is available about prognostic factors of arthroscopic capsular repair for peripheral triangular fibrocartilage complex (TFCC) lesions. The purpose of this study was to analyze factors that affect the treatment outcomes of arthroscopic capsular repair for peripheral TFCC tears. Methods: This study retrospectively enrolled 60 patients who were treated with arthroscopic outside-in capsular repair for peripheral TFCC tears. Functional survey, including pain numeric rating scale (NRS) on an ulnar provocation test, distal radio-ulnar joint (DRUJ) stress test, Disability of the Arm, Shoulder, and Hand (DASH) score, and satisfaction with treatment, was conducted at 12-month follow-up. Patients who were enthusiastic or satisfied comprised the satisfied group, and those who were noncommittal or disappointed the dissatisfied group. Demographic, clinical, and arthroscopic findings were compared between the satisfied and dissatisfied groups. Results: The mean pain NRS and DASH scores exhibited significant clinical improvement at the 12-month follow-up. Out of the total participants, 46 were satisfied and 14 were dissatisfied about the treatment, with significantly more female subjects in the dissatisfied group than in the satisfied one. The patients in the satisfied group had a shorter duration of symptoms, were more likely to have trauma history, and exhibited positive DRUJ stress test results compared to the dissatisfied group. There were no significant group differences in age, hand dominance, work level, and the extent of ulnar plus variance. Multivariable analysis revealed that female gender, a longer duration of symptoms, or negative DRUJ stress test results were associated with an increased disability after arthroscopic TFCC repair. Conclusion: Female gender, a longer duration of symptom, and a negative DRUJ stress test are associated with a higher likelihood of treatment failure after arthroscopic outside-in capsular repair of peripheral TFCC tears.
