Abstract

One hundred and fifty six patients were treated using the modified double suture technique for percutaneous Achilles tendon repair between 1994 and 1998. Endoscopy was used in 67 cases. The first ten cases were dropped (learning curve), 57 were followed (E-group). Percutaneous suture without endoscopy was performed in 89 patients. Two could not be followed (went abroad), so this group consists of 87 patients (P-group). Mean age: E-group 37.8 (22-60) years, P-group 38.9 (20-68) years. Male-female ratio: E 49/8, P 74/13. There were 54 and 83 athletes in groups E and P respectively. Follow-up period was 12-60 months. Overall re-rupture rate was 6/144 (4.2%). Two total and 3 partial re-ruptures were in the P-group, and 1 partial was in the E-group. Fusiform thickening of the tendon (delayed healing) occurred in 4 cases in each group. The mean plantar flexion strength compared with the non-affected side was 89% in the P-group and 86% in the E-group. The length of time before returning to sports activity ranged from 4 to 6 months after surgery in both groups. Subjective results were excellent to good in 88% (P-group) and in 89% (E-group) of the cases. On the basis of the results, the percutaneous double suture technique proved to be a simple and safe method for Achilles tendon repair with or without the use of an endoscope. The re-rupture rate was lower in the endoscopic controlled group. The basic goal of the endoscopy was to control the adaptation of the tendon ends. This method yielded further operative possibilities and benefits as well.
