Suture of fresh Achilles tendon rupture. Comparison of open with percutaneous suture technique

Abstract

The open repair of the acute Achilles' tendon rupture reduces the incidence of rerupture compared with nonsurgical treatment; however, it yields more surgical complications. Early mobilization of the patients improves the postoperative outcome. Percutaneous suture techniques have a low incidence of rerupture and improve the conditions for early mobilization. This study includes all patients (n = 97) with acute subcutaneous rupture of the Achilles' tendon with surgical treatment at the University of Heidelberg from 1992 to 1999. Open surgical repair and postoperative immobilization has been compared with a percutaneous suture technique and postoperative early mobilization. Altogether, 77 patients (80%) have been interviewed and 62 patients (65%) have undergone a clinical examination. There were local complications in 18% of the patients after open repair (n = 49) compared with 6% of the patients after percutaneous suture. In both groups there were two patients (4%) who sustained a rerupture. In the control group there were two patients with deep vein thrombosis (4%) and 1 lung embolism (2%). The clinical examination revealed no difference between open and percutaneous repair except for some disturbances in sensitivity of the sural nerve after percutaneous repair. The lower expenditure of therapy in percutaneous versus open sutures show the comparison of the hospitalization rates (29% versus 88%) and the rates of endotracheal anesthesia (53% versus 90%). Percutaneous suture technique for the repair of the Achilles' tendon is a simple and safe surgical procedure which allows early mobilization with a low rerupture rate. Thus this method should be performed as standard procedure for acute subcutaneous rupture of the Achilles' tendon.
