The anterior cruciate ligament (ACL) deficient knee has been subjected to various research and many conclusions
have been drawn to the loss of function in relation to it. ACL reconstruction is also very commonly done as
this ligament damage is the most common injury in sports. Muscle strength and proprioception have been
postulated to be affected alongside this injury. We conducted a cross sectional study in 19 patients who have
ruptured their ACL. We measured their muscle strength, thigh muscle bulk and proprioception in comparison
to their contralateral normal knee. The Biodex Isokinetic machine was used to measure the muscle strength
and proprioception. The thigh circumference was measured manually using a measuring tape. There was
significant reduction of muscle strength and thigh circumference in the ACL deficient limb as compared to the
normal side, p
