Abstract
The ACL is a central ligament of the knee. The main functional role of the ACL is to provide stability against anterior tibial translation (ATT) and internal rotation.
Pre rehabilitation improved patient reported symptoms (Modified Cincinnati Knee Rating System) at 12-weeks post operation. Increased subjective knee scores are associated with increased psychological readiness for return to activity, at 12-weeks post-operation; single leg hop distance/LSI scores were significantly higher in the group who received pre rehabilitation compared to the control group.
Goals and benefits of ACL prehabilitation are restore knee range of motion, lower extremity strength, especially quadriceps, knee stability, balance, proprioception, confidence in return to sport and reduce likelihood of reinjured or contra lateral injury. ACL contains mechanoreceptors which affect neuromuscular control of the knee beyond its mechanical function of maintaining knee joint stability
The surface EMG can be useful for evaluation of muscle strength and balance for pre operative rehabilitation preparation and also during rehabilitation after ACL injury.
