Abstract

PURPOSE: We assessed the clinical results of modified Brostrom procedure as a revision method after failure of a primary reconstruction.
MATERIALS AND METHODS
This is a retrospective study of seven patients treated with Modified Brostrom procedure after failed lateral ankle ligament reconstruction between 1996 and 2002. Instability symptom developed average 4.7 month after the initial reconstruction surgery at other clinics. All patients had significant functional impairment before surgery and not responded to conservative protocols. Modified Brostrom procedure was applied to all patients.
RESULTS
The average follow up was 51 months (18 to 84). Seven of eight patients had clinical stability following revision reconstruction, six patients (75%) returned to their previous functional level. American Orthopaedic Foot and Ankle Society ankle-hindfoot scores averaged 87.5. There is no difference in active or passive range of motion of plantar flexion or dorsiflexion when compared to the contralateral ankle. However, three patients were noted to have lost some degree of inversion when compated to contralateral ankle. Two patients had osteochondral lesion and multiple spurs and had pain around the ankle that prevented their full recovery. One patient complained of persistent pain which was considered complex regional pain syndrome.
CONCLUSION
Though the outcome of the Modified Brostrom procedure as a method of revision surgery was less satisfactory compared to the results of primary ankle reconstruction, it would be an appropriate option when concomitant abnormalities were not accompanying.
