Abstract
Percutaneous repair of a ruptured Achilles tendon has been shown to reduce wound healing problems but it has a high incidence of injury to the sural nerve. The Achillon Suture System is a new method utilising a small longitudinal incision. It passes a suture through the Achilles tendon leaving the suture purely within the tendon. The aim of this prospective study was to investigate the results of a new mini-open technique utilising a horizontal incision and early active mobilisation.
Following ethical committee approval 25 patients underwent repair of their ruptured Achilles tendon using the Achillon System. Rather than the longitudinal incision we used a horizontal incision and an accelerated rehabilitation program with a brace for 6 weeks post-operatively. Patients were followed up at 6 weeks, 3 months and 6 months post-op using the AOFAS and Leppilahti scoring systems.
There were no wound complications, re-ruptures or sural nerve injuries. All patients returned to work or their previous daily activities by 6 weeks (mean 22 days) post op. All patients had returned to driving by 6 weeks. One patient had 10° restriction in dorsiflexion at 3 months which prevented her return to running. She was back to running and had a full range of movement at 6 months. All other patients returned to sporting activities at 3 months but jumping sports such as basketball were discouraged until 6 months post-op.
We suggest that this modification of using a horizontal incision and early mobilisation enhances wound healing and allows early return to normal activities and sports. It is technically simple, utilises a small incision (still enabling visual confirmation that the tendon ends have been approximated) and reduces the risk of sural nerve injury seen in other mini-open or percutaneous techniques.
