    Abstract:
    BACKGROUND: A less-invasive technique to reconstruct chronic Achilles tendon rupture with transfer of the tendon of peroneus brevis is suitable in patients with a tendon gap less than 6 cm. PURPOSE: To report the results of a longitudinal study on reconstruction of chronic Achilles tendon rupture using a less-invasive peroneus brevis repair through 2 paramidline incisions. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Thirty-two patients underwent surgery for chronic Achilles tendon rupture with a tendon gap during surgery less than 6 cm, occurring between 60 days and 9 months preoperatively. All participants were prospectively followed for 5 to 8 years; final review was performed at 48.4 ± 13.5 months from the operation. Clinical and functional assessment (anthropometric measurements, isometric strength, postoperative Achilles tendon total rupture score) was performed. RESULTS: All patients were able to walk on tiptoes, and no patient used a heel lift or walked with a visible limp. No patient developed a clinically evident deep vein thrombosis or sustained a rerupture. Five patients were managed nonoperatively after a superficial infection of one of the surgical wounds. At final review, the maximum calf circumference remained significantly decreased in the operated leg (39.2 ± 6.2 cm [side with rupture] vs 40.9 ± 7.0 cm [uninjured side]; P = .04). The operated limb was significantly less strong than the nonoperated one (231.2 ± 132.4 N vs 275.3 ± 150.2 N; P = .033). The Achilles tendon total rupture score at final follow-up was 92.5 ± 14.2. CONCLUSION: The management of chronic Achilles tendon tears by a less-invasive peroneus brevis repair is technically demanding but safe. It allows good recovery, even in patients with a chronic rupture of 9 months' duration. These patients should be warned that they are at risk for postoperative complications and that their ankle plantar flexion strength is likely to be reduced.
