Comparison of modified Das De procedure with Du Vries procedure for traumatic peroneal tendon dislocation

Background For peroneal tendon dislocation, various surgical procedures have been described. Das De et al. reported good clinical results using retinaculum repair. However, their reports are limited to case series. We have simplified the Das De procedure since 1996. The purpose of this study is to investigate the clinical outcomes of our modified Das De procedure (MD) and compare these clinical outcomes to those of the Du Vries procedure (DV) that was performed in our hospital until 1996. Patients From 1996 to 2007, 19 patients were treated by MD and from 1988 to 1996, 15 patients were treated by DV. Results A mean preoperative Ankle-Hindfoot Scale was 78.4 points (range: 65–84) in the MD group and 77.2 points (range: 67–87) in the DV group. A mean postoperative Ankle-Hindfoot Scale was 93.4 points in the MD group and 89.4 points in the DV group. Two patients (13.3%) in the DV group suffered postoperative peroneal tendon redislocation. In the MD group, there was no postoperative peroneal tendon redislocation or complication related to skin incision. In athletes, 80.0% in the MD group and 54.5% in the DV group were able to return to their previous sports. The mean duration to return to sports was 2.9 months in the MD group and 3.9 months in the DV group ( p < 0.05). Conclusions MD provided similar or slightly better clinical outcomes with less complication as compared to DV. For athletes, the rate of return to sports was higher and the duration to return to sports was significantly shorter in the MD group.
