Chronic peroneal tendon dislocation is an uncommon disorder that frequently presents with concomitant pathology. Posterior fibular groove deepening and retinaculum repair have been increasing in popularity for treatment of peroneal tendon dislocations. The purpose of the present study was to introduce a posterior fibular groove deepening procedure using low-profile snap-off screws to securely and simply fix the fibrocartilaginous flap to facilitate faster rehabilitation and to assess the clinical outcomes of patients with chronic peroneal tendon dislocation and associated pathologic features. In the present retrospective case series, 34 ankles in 34 patients underwent the fibular groove deepening procedure using low-profile screws with superior peroneal retinaculum repair. The clinical outcomes were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale and patient subjective satisfaction rate. The time of return to recreational and sports activities was also assessed. Weightbearing ankle radiographs were evaluated to assess the stability of the flap by checking the screws. The mean follow-up period was 47.96 (range 12 to 142) months. The mean AOFAS scale score for all patients improved from 69.96 ± 13.14 to 87.72 ± 10.13 at the last follow-up examination (p < .001). Overall, 85.3% of patients subjectively rated their operative outcomes as excellent or good. The 18 (52.9%) patients with an isolated peroneal tendon dislocation had a faster return to recreational or sports activities than the 16 (47.1%) patients with concomitant pathologic features (2.95 ± 0.19 versus 4.14 ± 1.34 months; p = .002). No patient experienced residual dislocation, screw loosening, or irritation from the screws. The fibular groove deepening procedure using low-profile screws is be a simple procedure that offers rigid fixation. This leads to relatively fast rehabilitation and resumption of recreational or sports activities.
