Rehabilitation of the Operated Achilles Tendon: Parameters for Predicting Return to Activity

Abstract

Return to activity (RTA) following Achilles tendon surgery assessment criteria has not been generally adopted. A well-defined postsurgical rehabilitation regimen with 3 distinct criteria, yet easy to measure, can be used to assess the ability of patients undergoing Achilles tendon surgery to return to activity. We studied whether if patients were able to meet all 3 criteria, would this show significance in predicting the ability to RTA within a normal range. A total of 219 patients undergoing surgery on the Achilles tendon from 1990 to 2005 were retrospectively studied to evaluate for the ability to perform 5 sets of 25 single-legged concentric heel raises, along with symmetry of calf girth and ankle range of motion. Time of RTA and the ability to meet all 3 parameters was studied. If patients could meet all 3 criteria, they were allowed to RTA. This time postsurgery was recorded in weeks. Of the 219 surgeries reviewed, 149 were on males and 70 on females. Fourteen patients were unable to meet all 3 parameters evaluated above within the proposed time frames. The inability to meet all 3 criteria resulted in a delay to RTA ( P = .03). Eleven females had a delay in RTA as compared with 2 males ( P < .0001). RTA was different based on procedure. Meeting all 3 criteria was helpful in assessing if patients were able to RTA in the normal range. Patients who were unable to meet all 3 had a delay in RTA. Females were more likely to have a delay in RTA.
