Background: Complications of acute Achilles tendon rupture treatment are considered to negatively influence outcome, but the relevance of these effects is largely unknown.

Purpose: The Achilles Tendon Total Rupture Score (ATRS) was used to determine level of disability in patients with minimally invasive surgical Achilles tendon rupture repair with a complicated postoperative course.

Study Design: Case series; Level of evidence, 4.

Methods: The charts of 340 consecutive patients treated for an acute Achilles tendon rupture by minimally invasive surgical repair were reviewed. Complications were categorized as rerupture, severe wound infection, sural nerve injury, and other. Level of disability was evaluated by the 10-item ATRS with a sum score of minimum 0 to maximum 100 points.

Results: A total of 211 patients returned a completed questionnaire: mean follow-up was 6.2 years (range, 3-10 years). Mean ATRS for all 211 patients was 84 (95% confidence interval: 82, 87). The mean ATRS for the 135 (64%) uncomplicated cases was 89 of 100 points, 71 points for the 17 (8%) patients with a rerupture (95% confidence interval: 63, 79; P < .0001), 79 points for the 41 patients (19%) with a sural nerve injury (95% confidence interval: 74, 85; P = .0008), and 75 points for the 17 patients (8%) with another complication (95% confidence interval: 67, 83; P = .001). Of these other complications, 13 patients (6%) suffered a wound-healing complication considered minor. Their average ATRS score was 80 points (95% confidence interval: 71, 88.7; P = .0445). One patient suffered a severe wound infection as well, scoring 28 of 100 points. Rerupture significantly increased the risk of quitting or changing sport participation on the long term.

Conclusion: Long-term outcome after minimally invasive Achilles tendon rupture repair is excellent. Rerupture and severe wound infection are the most important complications with lasting negative effect on outcome. It justifies the use of rerupture as a relevant outcome measure in treatment evaluation.

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.
