Minimally invasive Achilles tendon repair: a modification of the Achillon technique.

BACKGROUND

The purpose of the study was to present the results of a new minimally invasive operative method for Achilles tendon (AT) ruptures that could reduce nerve injuries and add no extra cost.

METHODS

Thirteen patients with acute AT ruptures who were treated with minimally invasive surgery and followed for a minimum of 12 months were included. At the latest follow-up, American Orthopaedic Foot & Ankle Society (AOFAS) score, calf diameters, ability to walk on tiptoe, and ultrasound examination were evaluated. The average age was 42.8 years (range, 31-62 years). Average follow up was 24.5 months (range, 12-34 months).

RESULTS

AOFAS score was 92.5 (range, 85-100). Average calf diameters on the operated and nonoperated extremities were 38.9 cm (range, 36-44 cm) and 38.9 cm (range, 36-41 cm), respectively. On ultrasound examination, the site of the rupture was found to be 46.2 mm proximal from the calcaneal insertion, and the operated side was found to be significantly thicker than the nonoperated side (P = .008). There was 1 deep vein thrombosis, which recovered without sequelae. There were no wound problems, reruptures, or nerve injuries.

CONCLUSIONS

This new minimally invasive operative method was successful, showing good functional results and low complication rates. In our experience, the use of 3 continuous polyester sutures was less irritable with 3 knots.

LEVEL OF EVIDENCE: Level IV, retrospective case series.
