EVALUATION OF ARTHROSCOPIC TREATMENT OF TRIANGULAR FIBROCARTILAGEABSTRACT
Objective: To evaluate the clinical outcomes of surgical treatment by wrist triangular fibrocartilage complex (TFCC) lesions videoarthroscopy (VA) and analyze the correlation between magnetic resonance imaging (MRI) and intraoperative VA findings.
Methods: Cross-sectional study of 28 patients undergoing VA from February 2021 to September 2023, selected by predefined inclusion/exclusion criteria. The mean age was 39.6 years (range: 20–58), with a mean follow-up of 13.6 months (6–20). Twelve surgeries (42.9%) were on the right wrist and sixteen (57.1%) on the left. Functional assessment used the 11-item Quick-Dash questionnaire.
Results: Quick-Dash scores were excellent in 18 cases (64.3%), good in 7 (25.0%), and satisfactory in 3 (10.7%). MRI identified 4 (14.3%) extensive and 24 (85.7%) partial tears, while VA confirmed 2 (7.1%) extensive and 26 (92.9%) partial tears. Concordance between MRI and VA was found in 26 cases (92.9%).
Conclusion: Surgical treatment by VA resulted in predominantly excellent functional outcomes. There was high agreement between MRI and VA findings, indicating good sensitivity and specificity. Level of Evidence IV; Case Series.
