Outcomes after Primary Repair of Insertional Ruptures of the Achilles Tendon (Abstract)
Authors: Schipper ON, Anderson RB, Cohen BE
Achilles tendon insertional sleeve avulsions occur when the Achilles distal tendon sleeve ruptures off of its insertion into the calcaneal tuberosity, sometimes with a small bony fragment from calcific tendinosis. Little evidence exists describing the outcomes and rerupture rate after operative management of Achilles tendon sleeve avulsions.
A retrospective chart review was performed to identify patients who sustained an Achilles sleeve avulsion injury treated with operative repair between October 2005 and July 2014. A cohort of 16 patients from the general population and 12 professional athletes were included in the study. The primary outcome variable was rerupture of the Achilles tendon or need for revision surgery. Secondary outcome variables included the Coughlin Satisfaction Scale, visual VR-12, and Foot and Ankle Ability Measure (FAAM).
In the general population cohort, median follow-up was 8.1 years (range, 3.2-11.1 years). The median FAAM Activities of Daily Living score was 100 (range, 42.9-106), and the median FAAM Sports score was 100 (range, 7.1-103.6). The median VR-12 Mental Component Score was 66.9 (range, 45.6-71.8), and the median VR-12 Physical Component Score was 53 (range, 30.8-57.5). In the cohort of professional athletes, preceding insertional Achilles symptoms were present in 91.7% (11/12) of athletes for more than 9 months prior to rupture. All athletes returned to play with an average time of 13.4 months. No patients sustained a rerupture in the follow-up period.
Operative repair of Achilles tendon sleeve avulsions was safe and effective with high patient satisfaction and good clinical outcomes in patients from the general population.
