Abstract
Complete rupture of the Achilles tendon is a well described injury. Assessment of outcome and rehabilitation post surgery is difficult to qualify objectively.
We undertook a prospective evaluation of patients who had surgical repair of their ruptured Achilles tendon at our institution over a five year period. All patients underwent clinical and functional assessment. Objective function was evaluated using isokinetic testing on a Biodex dynamometer. Measurements included peak torque/body weight, average power, deficits, total work and range of movement. Studies were repeated at 60, 120 and 240 degrees/second. This was correlated with average time off work and time of return and level of sporting activities.
Although 53 patients were entered into the study, only 24 returned for full isokinetic testing. Males (16) were more commonly affected than females (9). Peak incidence was in the fourth and fifth decades of life. Mean hospital stay was 1.8 days. There were no problems with wound healing, and there were no infections.
22 of 25 patients returned to their pre-injury level of activity after an average of 6 months. Time off work averaged 14 weeks. 16 of 25 patients were the same or better when comparing peak torque/body weight, average power, maximum average peak torque and total work/body weight when compared with the unaffected limb.
Rehabilitation following Achilles tendon repair can be monitored clinically, however isokinetic testing can provide a more objective assessment of progress.
