Introduction And Importance:
The study is aimed to introduce an arthroscopic repair technique using a double-loop suture assisted by a direct dorsal approach for treatment of TFCC dorsal tear and report the results.
Case Presentation:
From 2021 to 2023, eight patients underwent arthroscopy and were diagnosed with dorsal tear of TFCC, who were included and retrospectively reviewed. The double-loop suture repair technique through direct dorsal approach (about 0.5 cm proximal to the 6 R portal) was applied.
Clinical Discussion:
The visual analogue scale (VAS) score, modified Mayo score, Disabilities of the Arm, Shoulder, and Hand (DASH) score, wrist range of motion, and grip strength were measured pre- and postoperatively. At the final follow-up (9-15 months, mean 11.8 months), all the eight patients achieved satisfactory results. The grip strength was increased significantly. The modified Mayo wrist and DASH scores showed significant functional improvement. The mean VAS score decreased from 4.0 to 1.1. After repairing dorsal tear of TFCC using double-loop technique through direct dorsal approach, satisfactory function and pain relief were achieved.
Conclusion:
The optimized approach and simple operation make it a safe and effective strategy for repair of TFCC dorsal tear.
Level Of Evidence:
IV; retrospective study.
