Injury to the lateral ankle ligaments caused by inversion of the ankle joint significant lower limb damage. This study aimed to assess patient with chronic lateral instability of the ankle and the return of movement function and stability of their operated ankle using the corrected Brostrom method at Baqiyatallah Hospital.
In this retrospective study, patients diagnosed with chronic lateral ankle instability from October 2019 to October 2022 were candidates for surgical treatment using the modified Brostrom method at Baqiyatallah Hospital. Information regarding age, gender, occupation of the patient, type of sport, the patient's anterior drawer examination (ADt), American orthopedic foot and ankle society (AOFAS) score, the range of motion (ROM) of the ankle joint, the pain, was recorded before surgery, three months And nine months after the operation.
Forty patients were included, and 70% were men. Improvement in the AOFAS scores from pre-operation (55.97±6.97) to 3 and 9 months after surgery (73.60±7.07 and 90.27±8.57) was significant (P < 0.001), and also, the AOFAS scores significantly improved between the 3 and 9 follow-ups (P < 0.001). The decrease in the pain was significant between pre-operation and three and nine follow-ups and also significantly reduced between the three-month follow-up and the nine-month follow-up (P< 0.001). The increase in the ROM was significant between pre-operation and three and nine follow-ups (P<0.001). There were significant differences between preoperation and 3-month and 9-month follow-ups after surgery in ADT and sprain (P<0.001).
This study showed that significant improvements in the AOFAS scale, pain, ROM, ADT, and sprain modified Broström repair could cause satisfactory results.
