Functional knee-braces are widely used to protect injured or reconstructed anterior cruciate ligaments, despite the fact that few scientific data support their efficacy. We studied the effect of the tibial strap of the Don-Joy brace used for 17 knees with cruciate ligament insufficiency. Injuries included the following: 12 knees, PCL 5 knees. The F-scan force distribution measuring system was used for the evaluation, and involved inserting a sensor-sheet between the strap and the tibia. We then

The strap forces increased in the stance phase during normal gait, although the transitional forces were small. We found that the functional knee-brace acted as a braking device for anterior posterior laxity of the tibia, but it did not go far enough. There is a current trend toward early postoperative mobilization and intensive rehabilitation after reconstruction of the cruciate ligament with a bone -patellar tendon-bone graft. In this situation the usefulness of braces must not be over inflated.
