Knee brace after bone-tendon-bone anterior cruciate ligament reconstruction. Randomized, prospective study with 2-year follow-up.

Abstract

In a prospective study 60 patients were randomized to brace and no-brace groups after bone-tendon-bone anterior cruciate ligament reconstruction. The brace group wore a rehabilitation orthosis for 12 weeks postoperatively, while the no-brace group was mobilized immediately, and crutches were discarded 2 weeks postoperatively. The groups were comparable with respect to age, gender, time from injury to surgery, knee score (Lysholm), activity level (Tegner), degree of laxity and isokinetic muscle torque. Although compared with the preoperative situation patients in both groups had significantly improved, there were no differences between the groups 1 and 2 years postoperatively in terms of functional outcome (Lysholm and Tegner scores), stability of the knee or isokinetic muscle torque.
