Lunotriquetral Ligament All-Inside Arthroscopic Repair: Technique and Results

Abstract The objective is to describe a technique for treating lunotriquetral ligament (LTL) injuries through an arthroscopic reinsertion of the volar or dorsal LTL and reinforce with capsulodesis and to present the results obtained. A retrospective, analytical, clinical study was conducted on 13 consecutive patients with LTL injuries. Range of joint motion, grip strength, pain according to the visual analog scale, functional outcomes according to the Mayo Wrist Score, and the QuickDASH Score, as well as complications and reinterventions, were assessed preoperatively and at 1, 3, 6, and 12 months postoperatively. Thirteen patients with European Wrist Arthroscopy Society type IIIA or IIIC LTL injuries were evaluated. The mean age was 39.15 ± 3.43 years (range: 16–59), and 54% were male. Overall, 54% had type 3A lesions and 46% 3C. All underwent arthroscopic reinsertion with capsulodesis reinforcement. Significant improvements in pain, grip strength, range of motion, and functional scores were observed at 3, 6, and 12 months postoperatively, with excellent results. From the sixth month onward, no statistically significant differences were observed when compared with the contralateral wrist. All-inside arthroscopic LTL repair is a safe and effective treatment option for acute injuries and certain early chronic injuries without nonreducible instability or chondral degeneration. This procedure allows for the simultaneous assessment and repair of volar, dorsal, or combined tears while preserving joint mobility and minimizing morbidity. Compared with open repair, this minimally invasive approach may enable faster recovery and fewer complications though larger comparative studies are needed to confirm its long-term benefits.
