[Percutaneous technique for Achilles tendon repair with the Dresden Instruments].

BACKGROUND: The percutaneous technique for Achilles tendon repair with the Dresden instruments (pDI suture) was developed to minimize the typical problems of percutaneous Achilles tendon sutures.

METHODS: From 1 January 2000 to 31 December 2003, the pDI suture was performed in 61 patients with 62 Achilles tendon ruptures. We reviewed 39 of 47 patients (83%) with 40 ruptured Achilles tendons who had undergone percutaneous repair at a minimal interval of 12 months after the operation.

RESULTS: In this study we observed no sural nerve injuries. The rerupture rate was 2/62 or 3.2%. In one patient (1.6%) a superficial late infection occurred after tendon healing. Using the criteria of Trillat and Mounier-Kuhn, 62% of the results were very good and 30% good. The average AOFAS score was 96 (78-100) points; 78% of the patients assessed the result of treatment as very good and 20% as good.

CONCLUSIONS: The percutaneous suture using the Dresden instruments is a minimally invasive operative treatment of Achilles tendon rupture resulting in nearly all very good and good subjective and clinical results. It combines a low rerupture and infection rate with a minimized risk of sural nerve injury.
