The aim of this study was to assess early and late results of
surgical treatment of acute patellar tendon rupture. Our hypothesis was that
functional outcome is satisfactory. METHODS: A retrospective study included 38
knees in 37 patients (4 female, 33 male). Mean age was 42.6+/-9.9years (range,
23-81years). Lesions comprised 15 tendon body ruptures, 20 avulsions from the tip
of the patella and 3 avulsions from the anterior tibial tuberosity. Tendon repair
was protected in more than 95% of cases by a reinforcement frame: hamstring (21
cases), synthetic ligament (12 cases) or metallic wire (3 cases). Results were
evaluated in 2 steps: on patient files at a mean follow-up of 7.1months (range,
3-24months) to assess complications and early functional and radiological
results; and by phone at a mean follow-up of 9.3years (range, 19-229months) in
order to assess long-term functional outcome on Lysholm score and patient
satisfaction. RESULTS: Thirty-one knees were assessed at a mean 7.1months. Mean
knee flexion was 128.5 degrees +/-7.5 degrees (range, 85 degrees -150 degrees ),
extension -1 degrees (range, -15 degrees to 0 degrees ) and Caton-Deschamps index
0.96 (range, 0.57-1.29). Twenty-three knees were further assessed at a mean
9.3years. Mean Lysholm score was 93.7 points (range, 61-100). Ninety-six percent
of patients were satisfied or very satisfied with the result. All had returned to
their previous job, and 20 had returned to sports activities, including 8 at
pretrauma level. CONCLUSION: Patellar tendon rupture has good prognosis if
diagnosis and surgical treatment is early. LEVEL OF EVIDENCE: IV: retrospective
study.
