Results of surgical versus non-surgical treatment of Achilles tendon rupture.

Between 1990 and 2001, 292 patients with acute Achilles tendon rupture were admitted to our institution. Depending on the day of admission patients were allocated either to the Department of Trauma Surgery or to the Department of Orthopaedics. Two hundred and twelve patients (mean age 37+/-9.4 years) were treated with surgical suture followed by plaster for 6 weeks. Eighty patients were treated non-surgically with splinting for 12 weeks. For both groups mean follow-up was 6+/-3 years. There were 14 re-ruptures, ten after surgical repair and four after non-surgical treatment. In the surgical group there were seven major wound problems, 11 minor wound complications and six patients with complaints from the sural nerve. In the non-surgical group one patient suffered a pulmonary embolism after a re-rupture, 3 months after the initial rupture. There was no difference in mean ankle score and patient-satisfaction score between groups. Only 52% regained their original sports activity level, slightly better in the surgically treated group. With a non-significant difference in re-rupture rate but relatively more complications after surgical repair, non-surgical treatment is preferred. With a slightly better recovery of sports activity after surgical repair, this might be used as an argument for surgical treatment in young athletes.
