Anterior cruciate ligament reconstruction with a bone-patellar tendon-bone graft followed by either accelerated or nonaccelerated rehabilitation produces the same increase of anterior knee laxity. Both programs had the same effect in terms of clinical assessment, patient satisfaction, functional performance, and the biomarkers of articular cartilage metabolism. There is concern that the cartilage biomarkers remained elevated for an extended period.

Treatment of first-time grade I and II ankle ligament sprains with the Air-Stirrup brace combined with an elastic wrap provides earlier return to preinjury function compared to use of the Air-Stirrup brace alone, an elastic wrap alone, or a walking cast for 10 days.

In this investigation we evaluated the effect of ACL reconstruction and functional knee bracing on knee proprioception. Twenty subjects who experienced acute ACL disruption and underwent reconstruction with a bone-patellar tendon-bone graft participated in a controlled rehabilitation program and were studied at a mean follow-up of 2 years. A control group of ten subjects were also studied. In both groups proprioception was evaluated by measuring the threshold to detection of passive motion (TDPM) with the knee at 15 degrees of flexion with and without a functional knee brace applied. The Knee Osteoarthritis Outcome Score, Cincinnati knee score, and two functional knee tests were also used as outcome measurements. Anterior-posterior displacement of the tibia relative to the femur was evaluated with the KT-1000 arthrometer. There were no significant differences in TDPM between the ACL-reconstructed and contralateral knees, or between the ACL reconstructed group and the healthy control group. Bracing did not produce a significant change in the TDPM for the ACL-reconstructed group or for the control group. There were low to moderate correlations between TDPM and the other outcome measurements. This study indicates that there is no significant differences in proprioception between the ACL-reconstructed knee and the contralateral uninvolved knee 1 year or more after surgery. Functional knee bracing does not seem to improve proprioception in patients who have undergone ACL reconstruction and been followed up on average 2 years after surgery.
