Comparison of the curative effect of modified medial arc incision of achilles tendon and traditional straight incision in the treatment of old achilles tendon rupture.

Modified medial arc incision of Achilles tendon and traditional straight incision were applied to treat 50 cases of old rupture of Achilles tendon. Among them, there were 20 cases involved in the modified medial arc incision of Achilles tendon (group A).Furthermore, 30 cases accepted traditional straight incision treatment (group B). The same rehabilitation program was applied in both groups, combined with the evaluation using the clinical objective examination, subjective satisfaction of patients and the American Orthopaedic Foot and Ankle Society (AOFAS) scores. There was significant difference between group A and group B in the recovery time to normal motion ranges (P<0.05). The average AOFAS score of group A was higher more than (P<0.05). In addition, patients from the two groups did not suffer from cutaneous sensory disturbance of the dorsum of foot due to sural nerve injury, or no deep venous thrombosis. Except for 1 patient with deep infection, all patients recovered to normal motion ranges. The overall curative effect of modified medial arc incision of Achilles tendon is superior to traditional straight incision in the treatment of old Achilles tendon rupture, which is conducive to the early recovery to normal motion ranges before injury.
