The Anatomy of the MCL
MCL stands for “medial collateral ligament.” A ligament is a fibrous of connective tissue that connects bones to each other and keeps joints stable. The MCL runs from the inside of your upper shin bone to the inside of your bottoms thigh bone and keeps the knee from moving side to side. Its primary purpose is to withstand valgus pressure, or the knee being forced unnaturally inward. It combines with three other ligaments to keep the knee stable:
- ACL (anterior cruciate ligament), which goes through the middle of your knee and controls rotation and prevents the knee from bending inward
- PCL (posterior cruciate ligament), which crosses the ACL in the middle of the knee and prevents excessive posterior translation of the tibia relative to the femur
- LCL (lateral collateral ligament), which runs along the outside of the knee from the thigh bone to the fibula (the smaller bone between the knee and ankle) and helps keep the outer side of your knee joint stable
The knee is known for being one of our most complex joints. Healthy structure and function depends on surrounding bone, muscle, tendons, and ligaments. There are countless knee injuries that can limit or completely restrict your mobility and ability to do what you love most, or just live a pain-free day-to-day life. Specific physical therapy exercises and other physician-prescribed treatment plans have been demonstrated through research and analysis to help patients mitigate pain and swelling and return to optimal movement health.

What Types of MCL Injuries Are There?
In general, an MCL injury is either a sprain, which stretches the ligament farther than is naturally, or a tear, where the ligament is either partially or completely torn or separated from the bone. There are three grades to MCL injuries:
- Grade 1 — A grade 1 sprain or tear means that the ligament has been stretched, and less than 10% of the MCL has been torn. It’s typically a mild injury, and your knee will still be stable. You will likely experience some tenderness and mild pain.
- Grade 2 — This is more significant tearing, most commonly to the middle layer of the ligament. You will probably lose some stability in the joint, and the knee will likely be loose when manipulated manually. Symptoms of a grade 2 MCL injury generally include much more noticeable pain.
- Grade 3 — A grade 3 tear is a complete tear, or separation from the bone. Your knee will be significantly unstable. You will likely feel intense pain and several other symptoms. Grade 3 MCL injuries often occur alongside other knee injuries such as ACL tears.
However significant your MCL injuries, the team of professional Affton, MO physical and occupational therapists at Axes can, alongside your physician, create a comprehensive and personalized plan to get you back to the activities your love most without incurring further injury.
MCL Injuries: Causes and Symptoms
40% of all knee injuries involve damage to a ligament, and most of the time that ligament is the MCL. Most MCL injuries occur due to a force to the exterior of the knee. MCL injuries can also by the knee rotating too forcefully. They can also happen because of landing or excessive bending, such as if your foot stays in one place while your leg keeps moving.
MCL injuries are common in athletes in contact sports and in athletic events that require a lot of torque being placed on the body such as football, soccer, skiing, basketball, and tennis. They can also occur in people who have to hunch over and lift heavy objects, either for athletic training or in the course of their employment.
Common Symptoms of MCL Injuries

- Hearing or feeling a popping sound or feeling
- The knee being unstable
- Pain or discomfort when trying to bear weight
- Contusions
- Tenderness along the inside of the joint
- Swelling, either on the inside of the knee or the entire knee joint
Sometimes you may feel a “wobbly” sensation, while other times you’ll barely be able to move the knee. Any time you feel pain or instability in your knee, cease any strenuous activity immediately and seek medical treatment for a diagnosis.

Diagnosing an MCL injury requires going to a physical examination. The examination will usually start with a doctor or physical therapist in Affton, MO asking how the injury occurred. They’ll then bend your knee and apply slight pressure to the outside of it, noting your pain level and whether or not your knee is unstable. They’ll also gently feel for swelling, and may compare your injured knee to the healthy one.
Most physical therapists or doctors that specialize in mobility of the human body in Affton, MO are qualified to diagnose an MCL injury with a physical examination. A phsycian may also order the following imaging tests to check the severity of the injury and whether or not you have suffered other damage to the knee:
- An MRI (magnetic resonance imaging), which uses a magnetic field and computer-generated radio waves to create detailed images of the inside of your knee
- An ultrasound, which uses sound waves and can be helpful in checking the severity of your injury
- An X-ray, which, while it won’t show the MCL or other ligaments, to insure your femur, patella, tibia, and fibula have not fractured
Axes Physical Therapy also offers injury screening injury screenings at no cost or obligation to you. While we can determine if you have suffered an MCL sprain or tear, Missouri Revised Statute §334.506 mandates a prescription in order to officially begin physical therapy treatment.
