Primary Patellar Tendon Repair and Early Mobilization: Results in an Active-Duty Population
ABSTRACT: We retrospectively reviewed 13 patellar tendon repairs done over 32 months at a tertiary care, military medical center. Early mobilization was initiated within 2 weeks postoperatively. Clinical and functional results were statistically examined with relation to age, timing of surgery, length of follow-up, quadriceps atrophy, extensor lag, patella position, and time to full duty. At an average of 24 months’ follow-up, six patients (46%) had thigh girth atrophy, and one patient (8%) had an extensor lag >5°. Mean Lysholm score was 84
(range, 57 to 100). Maximum postoperative Tegner activity scores averaged 7.1 (range, 5 to 10). Clinical results classified five cases as excellent, three good, three fair, and two poor. Functional results classified three cases as excellent, four good, two fair, and four poor. Time to return to duty averaged 13 months. Our results suggest that adequate extensor function can be restored after primary repair and immediate motion therapy.
