The primary role of the anterior cruciate ligament (ACL) is to resist anterior subluxation of the tibia. As such it plays an important role in fixating the knee joint and preventing knee instability. As each ACL has it’s own unique characteristics it can be damaged in different ways, diagnostics on individual levels are needed to determine the most appropriate rehabilitation protocols. For diagnosing ACL tears there are very common and reliable but subjective methods, such are anterior drawer and Lachman tests and objective methods like stress arthrometry testing and magnetic resonance imaging. However there aren’t any selective and objective tools available for testing muscle atrophy which is a significant associated condition.

TMG is a noninvasive, selective method for measuring the mechanical contractile properties of skeletal muscles when monitoring, the ACL rehabilitation process prior to and post-surgery, which enables optimization of the rehabilitation process. In the study we have measured patients just before and after ACL reconstruction and demonstrated the sensitivity of the TMG method of monitoring muscle atrophy and hypertrophy during rehabilitation process.
