Abstract
Introduction: Current evidence for treatment of Achilles tendon rupture suggests that open surgical repair reduces the re-rupture rate compared to conservative treatment, but with a higher risk of infection. Modern non-surgical treatment and surgical aftercare involves early weight-bearing in functional orthoses. It is therefore appropriate to measure the re-rupture rates and outcomes in patients treated in this manner.
Materials and methods: Between 2002 and 2008 our unit prospectively collected data on 80 patients treated with a below-knee functional orthoses for complete Achilles tendon rupture. Patients made their own choice of treatment following evidence-based counselling. The patients were treated either surgically or conservatively and entered the appropriate arm of the standard orthotic and early weight-bearing treatment protocol. Patients were contacted by telephone or post for follow-up and completed a VISA-A and Achilles Total Rupture Score (ATRS) questionnaire.
Results: There were 61 Males, 19 Females with an age range of 24–80 (median 42). The median time in the functional brace was eight weeks. 51 patients were treated conservatively and 29 patients surgically. The conservative group were a decade older (median age 47y, range 27–80) than the surgical group (median age 37y, range 24–55y). In the non-operative treatment group the re-rupture rate was 3.9% (2/51, 95% confidence interval 0.5–13.5%). In the surgical group it was 3.4% (1/29, 95% confidence interval 0–17.8%), in this group the wound infection rate was 6.8% (2/29, 95% confidence interval 0.9–22.8%) with no nerve injuries reported. The median ATRS was 82 in the conservative group and 95 in the surgical group. The median VISA-A scores were 57 and 92 respectively.
Discussion: Our case series shows comparable low re-rupture rates in both groups. Functional scores, using the newly validated ATRS score, were lower in the non-surgical, older group.
Conclusion: Functional care after surgical and non-surgical treatment of Achilles rupture produces similar re-rupture rates.
