Treatment Options and Recovery for MCL Sprains and Tears
The knee may feel as if it is about to give out. Instability is usually associated with more severe MCL tears. Pain when bearing weight, such as when walking, sitting down, or rising from a chair.
The medial collateral ligament (MCL) is one of four ligaments that keep the knee joint stable. 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 inner side of the knee joint. That's why it's so painful when the ligament is stretched too much or torn.
Description. There are two collateral ligaments of the knee: the medial collateral ligament (MCL) and the lateral collateral ligament (LCL). Injuries of the MCL are much more common, owing to its exposure to damage from a blow to the outside of the knee, creating a so-called valgus force.
The medial collateral ligament (MCL) is a wide, thick band of tissue that runs down the inner part of the knee from the thighbone (femur) to a point on the shinbone (tibia) about 4 to 6 inches from the knee.
Grade 1: A grade 1 MCL tear is a mild tear in which less than 10% of fibers in your ligament are torn and your knee is still stable. You'll likely have some tenderness and mild pain if you have a grade 1 tear.
The MCL originates on the medial aspect of the distal femur and inserts on the medial aspect of the proximal tibia several centimeters below the joint line. Its deep fibers are intimately interlaced with the joint capsule at the level of the joint, and the medial meniscus is attached directly to it.
A medial collateral ligament (MCL) injury is a stretch, partial tear, or complete tear of the ligament on the inside of the knee. It is one of the most common knee injuries and results mostly from a valgus force on the knee.
A medial collateral ligament (MCL) injury is a sprain or tear to the medial collateral ligament. The MCL is a band of tissue on the inside of your knee.

The lateral collateral ligament (LCL) is a fibrous band of tissue that connects the bottom of the thigh bone (femur) to the top of the smaller shin bone (fibula). The LCL is located on the outside of the knee joint, also called the lateral knee joint.
While MCL injuries are generally a result of a direct blow to the outer side of the knee that pushes the knee inwards, meniscus injuries are usually the product of direct pressure on the knee following a forced twist or rotation.
A sprain stretches the ligament, which can become loose after a severe injury. A tear is a more severe injury that splits the ligament in two. When someone tears the MCL, it may not hold the knee in place as securely. MCL injuries often happen during contact sports.
Grade II - partial tear (rupture) of the ligament, visible swelling and noticeable tenderness, but without joint instability (or with mild instability). Grade III - a severe sprain: complete rupture of the ligament with significant swelling and with instability of the joint.

Use secondary code (s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code. Type 1 Excludes.
