Abstract

PURPOSE
To evaluate the efficacy of the arthroscopic exploration combined with modified Brostrom operation (MBO) for the treatment of chronic lateral ankle instability (CAI).
MATERIALS AND METHODS
Sixty patients who diagnosed a CAI were performed MBO. We divided to 2 groups, whether simultaneously inspected by arthroscopy (group B) or not (group A). The both group's results were compared according to American Orthopedic Foot and Ankle Society Ankle-hindfoot score (AOFAS), functional ankle score and visual analog scale (VAS) at preoperative and final follow-up period.
RESULTS
There were no significant differences of AOFAS, functional ankle score and VAS between both groups at final follow-up. However, in group A, 2 cases associated with medial ankle instability and syndesmotic injuries were did not diagnosed preoperatively, showed poor prognosis. In group B, one case had a permanent peroneal nerve symptom. The match rate of intra-articular lesions between preoperative diagnosis and postoperative arthroscopic diagnosis was 30% in group B.
CONCLUSION
Combination of arthroscopic exploration and MBO is effective strategy for intra-operatively discrimination of intra-articular associated lesions for CAI.
