Study Comparing Modified Brostrom Repair With and Without Suture Tape for Chronic Lateral Ankle Instability in Adults

What this Trial Is About

This research focuses on chronic lateral ankle instability CLAI, a condition where the ankle frequently gives way, often worsened by generalized joint laxity GJL. Researchers are exploring whether adding suture tape to the modified Brostrf6m repair MBR, a surgical method for CLAI, can provide better ankle stability and strength. The study aims to understand the outcomes and possible risks, such as suture tape rejection, associated with this surgical augmentation. Participants will undergo one of two surgical procedures the open modified Brostrf6m repair with suture tape augmentation or the standard modified Brostrf6m repair alone. Both groups consist of patients diagnosed with CLAI and GJL. The study compares these two procedures to assess differences in postoperative ankle stability and function over time. During the study, participants ankle function will be evaluated using the American Orthopaedic Foot and Ankle Society AOFAS score at 3 months, 6 months, 1 year, and 2 years after surgery. Additional assessments include stress radiography measuring anterior displacement and talar tilt angle at 2 years and monitoring the rate of re-injury over the same period. The total study duration extends through these follow-up assessments to monitor outcomes and safety.
