What is the medial collateral ligament also known as?
MCL injuries often occur in sports, being the most common ligamentous injury of the knee, and 60% of skiing knee injuries involve the MCL). NB The MCL is also known as the tibial collateral ligament (see image) The MCL. Provides valgus stability to the knee joint.
What are the names of the collateral ligaments?
The collateral ligaments of the knee are located on the outside part of your knee joint. They help connect the bones of your upper and lower leg, around your knee joint. The lateral collateral ligament (LCL) runs on the outer side of your knee. The medial collateral ligament (MCL) runs along the inside of your knee.
What motions does the medial collateral ligament MCL resist?
The MCL spans the distance from the end of the femur (thigh bone) to the top of the tibia (shin bone) and is on the inside of the knee joint. The medial collateral ligament resists widening of the inside of the joint, or prevents “opening-up” of the knee.
How do you test a medial collateral ligament?
The valgus or abduction stress test evaluates the medial collateral ligament (MCL). To perform this test, place the knee in thirty degrees of flexion. While stabilizing the knee, press firmly against the outside portion of the knee while holding the ankle stable.
