The MCL and LCL are two of the four major ligaments that support and stabilise the knee.
The MCL is a strong broad band of ligament which is situated on the medial side of the knee. Whilst the LCL is a thinner cord like ligament spanning along the lateral aspect of the knee.
The terms valgus and varus refer to angulation (or bowing) within the shaft of a bone or at a joint. Valgus is a term for a lateral angulation of the distal segment of a bone or joint. Whilst Varus is the medial deviation of the distal aspect of the bone.
Varus and valgus always refer to the direction that the distal segments of the joint points.
The valgus stress test allows you to examine the medial aspect of the joint for any laxity. An increase in laxity and joint space or reports of pain from the patient during this examination, usually indicates damage to the medical collateral ligament.
The Varus Stress Test is the opposite to the Valgus in that it allows you to examine the lateral aspect of the joint for any laxity. As with the Valgus Stress Test, any excessive laxity in the joint or reports of pain from the patient would usually be an indication of some damage to the lateral collateral ligament.
