The Short Term Results of All-inside Arthroscopic Repair of the Triangular Fibrocartilage Complex Type 1B Tear by Knotless Suture Anchor

ABSTRACT

PURPOSE: We studied the short term results of the arthroscopic repair of 1B type triangular fibrocartilage complex (TFCC) tear using a knotless suture anchor. METHODS: We evaluated 23 patients who underwent all-inside arthroscopic TFCC repair using a knotless suture anchor. The average follow-up duration was 6.6 months (range, 3-10 months). Mean duration of symptom was 10.9 months (range, 1 week-7 years). The arthroscopic finding documented 15 type 1B, 2 1B with 1D, and 6 1B with 2C lesions. All showed the positive hook test. The concomitant pathologies were 16 scapholunate injuries and 10 lunotriquetral injuries. TFCC tears were repaired by the knotless suture anchor. The Wafer procedure was done for 2C lesions. RESULTS: According to Mayo modified wrist score, the result was excellent in 4, good in 14 and fair in 5. Nineteen patients (82.6%) could return to his job or hobby. CONCLUSION: The all-inside arthroscopic repair using knotless suture anchor for TFCC 1B tear can provide good results. The appropriate management should be done for the concomitant pathologies for the better results.
