Abstract

BACKGROUND: We analyze the functional evaluation, posterior stability after surgery of acute injuries in the femoral detachment and tibial avulsion fracture of posterior cruciate ligament.
MATERIALS AND METHODS
Twenty two patient who underwent primary repair were followed more than one year after operation (mean follow-up 33.7 months). The patients were evaluated with KT 2000 arthrometer and posterior stress test for posterior stability. Lysholm knee score was used for knee function.
RESULTS
Lysholm score revealed 85.3 in femoral detachment group and 91.1 in tibial avulsion fracture group (p<0.05). Posterior displacement of the posterior stress test showed 17.2 mm at initial injury and 8.6 mm at last follow up in femoral detachment group. 16.8 mm at initial injury and 7.1 mm at last follow up in tibial avulsion fracture group There revealed the tendency of the improved posterior stability of the tibial avulsion group compared with femoral detachment group, but there showed no statistical significance in KT 2000 arthrometer and posterior stress x-ray.
CONCLUSION
Functional results of tibial avulsion fracture group revealed the better outcome compared with femoral detachment group, but the degree of posterior stability in tibial avulsion fracture group showed no statistical significance in posterior stability.
