Percutaneous Repair Followed by Accelerated Rehabilitation for Acute Achilles Tendon Ruptures

Abstract

Purpose. To evaluate the outcome after percutaneous repair followed by accelerated rehabilitation for acute Achilles tendon ruptures. Methods. 21 men and 9 women (mean age, 41 years) underwent percutaneous repair by a single senior surgeon for acute Achilles tendon ruptures, followed by early weight bearing and accelerated rehabilitation. Outcome measures included the Achilles tendon re-rupture rate, the Achilles tendon total rupture score (ATRS) at 3 and 6 months, the incidence of sural nerve injury, wound infection, wound dehiscence, patient satisfaction, and the time to return to pre-rupture activity. Results. The mean follow-up period was 12.5 months. The mean ATRS score improved from 57.65 at 3 months to 86.95 at 6 months (p<0.001). No patient had intra-operative complications, tendon re-rupture, sural nerve injury, wound dehiscence, or deep infection. Two patients developed a superficial wound infection, which was resolved with oral flucloxacillin. Two patients had a mass at the transverse incision, but neither had any symptoms or functional restriction. All patients were able to bear full weight comfortably without the walker boot at 8 weeks, and return to their work by 3 months. The mean time to return to pre-rupture activity, including sports, was 10.4 months. The mean satisfaction rate was 87% at 6 months. Conclusion. Percutaneous repair of the Achilles tendon followed by early weight bearing and accelerated rehabilitation achieves good functional outcome.
