Abstract:

BACKGROUND: There are many repair and reconstruction methods to restore the stability of lateral ankle joint.
OBJECTIVE: To compare the mechanical changes of modified Karlsson procedure and modified Broström procedure for the treatment of lateral chronic ankle instability.
METHODS: Seventy-three patients with lateral chronic ankle instability were enrolled, among whom, 43 consecutive patients were treated with modified Broström procedure and followed-up for average (50.8±26.5) months, and 30 consecutive patients underwent modified Karlsson procedure and followed-up for (49.5±11.1) months. Chondral lesions, American Orthopaedic Foot and Ankle Society score, Mazur score, Tegner score, satisfaction score and re-injury situation were recorded before and after treatment. Objective examinations including drawer test and inversion stress test were also done for assessment.
RESULTS AND CONCLUSION: 38.4% patients had chondral lesions, and 40.5% lesions occurred in the anteromedial facet of the talocrural joint (talus zone I and tibia region I). Mazur score and Tegner score were significantly improved postoperatively in modified Broström group and modified Karlsson group. There were no significant differences on Mazur score and Tegner score between two groups. The improved American Orthopaedic Foot and Ankle Society score in the modified Karlsson group was significantly higher than that in the modified Broström group. The drawer test and inversion stress test were negative in two groups, except positive in one patient in modified Broström group. The treatment time in the modified Karlsson group was significantly shorter than that in the modified Broström group, and there was no significant difference in satisfaction score between two groups. There were two cases of re-injury in modified Broström group while one case in modified Karlsson group. Modified Karlsson procedure has the treatment effect similar to modified Broström procedure, but it is easier to operate.
