Abstract

Purpose

Arthroscopic repair of a peripheral triangular fibrocartilage complex (TFCC) tear is a promising, minimally invasive surgical technique, especially in patients with symptomatic distal radioulnar joint (DRUJ) instability. The purpose of this study was to evaluate the clinical result of arthroscopic one-tunnel transosseous foveal repair for peripheral TFCC tears.

Methods

Sixteen patients who underwent TFCC foveal repair were retrospectively evaluated. The mean follow-up period was 31.1 months. The torn TFCC of all patients was repaired with the arthroscopic one-tunnel transosseous foveal repair technique. Postoperative outcomes were evaluated using the visual analogue scale (VAS) for pain, wrist range of motion, grip strength, Mayo wrist score, Quick Disabilities of the Arm, Shoulder and Hand (Quick DASH) score, and postoperative complications.

Results

On arthroscopic examination, all 16 patients showed Palmer 1B type peripheral TFCC tears with foveal disruption. Among them, 13 patients had a proximal component TFCC tear (Atzei class 3) and 3 patients had a complete TFCC tear (Atzei class 2). At the final follow-up, the mean range of the pronation–supination arc (P = 0.03) and grip strength (P = 0.001) was significantly increased. Twelve patients had normal stability of the DRUJ and six patients showed mild laxity compared with the contralateral side. The mean VAS for pain perception decreased from 3.7 to 0.8 (P = 0.001). The modified Mayo wrist (P = 0.001) and Quick DASH (P = 0.001) scores showed significant functional improvement. No surgery-related complications occurred.

Conclusions

The present study shows that arthroscopic one-tunnel transosseous repair is a good treatment strategy for TFCC foveal tears in terms of reliable pain relief, functional improvement, and re-establishment of DRUJ stability.
