The Anatomy of the MCL
MCL stands for “medial collateral ligament.” A ligament is like a strong, firmly attached rope that connects bone to bone and helps hold structures with the musculoskeletal system together. The MCL connects your upper shin bone to the inner surface of the bottom thigh bone, running along your inner knee, and keeps the knee from moving side to side. Its primary purpose is to withstand valgus stress, or the knee being pushed too far towards the other one. 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 controls forward movement
- PCL (posterior cruciate ligament), which forms an “X” with the ACL in the middle of the knee and the femur from sliding off the tibia
- LCL (lateral collateral ligament), which runs along the outside of the knee from the thigh bone to the fibula (the smaller bone in the lower leg) and helps keep the outer side of your knee joint stable
The knee is one of the largest joints in the human body. Healthy structure and movement depends on surrounding bone, muscle, tendons, and ligaments. There are a variety of knee injuries that can have tremendous consequences for your mobility and compete like you’re used to, or just get around the house pain-free. Specific physical therapy techniques and other treatment modalities, prescribed by a doctor, have been demonstrated through research and analysis to help those who have suffered an MCL injury mitigate pain and swelling and get back to optimal movement health.

What Types of MCL Injuries Are There?
For all intents and purposes, an MCL injury either involves a sprain, which stretches the ligament beyond its normal range of motion, or a tear, where the MCL is either partially or completely torn or separated from the bone. MCL injuries are “graded” in three levels:
- Grade 1 — A grade 1 MCL injury refers to a sprain, or a tear where less than 10% of the the fibers in your ligament are torn. It’s typically a mild injury, and your knee largely remains stable. Your knee will feel tender, and you may also experience mild pain.
- Grade 2 — This is more significant tearing, generally to the middle layer of the MCL. You will probably lose some stability in the joint, and the knee will likely be loose when manipulated manually. Pain is much more severe in a grade 2 MCL injury.
- Grade 3 — This injury is a complete tear to both the superficial and deep parts. You will retain little to no stability. Pain will be intense and you’ll likely feel a wide array of symptoms. Grade 3 MCL injuries often occur alongside other knee injuries such as ACL tears.
Whatever grade MCL injury you have, our expert St. Clair, MO physical and occupational therapists at Axes can, as a team with your physician, develop an extensive plan specially made for you and your injuries aimed at returning you to the life you’re used to safely.
What Causes MCL Injuries?
40% of all knee injuries involve damage to a ligament, and the MCL is the most commonly injured ligament. Most people often suffer and MCL injury because of physical trauma on the outside of the knee. MCL injuries can also occur if the knee is rotated more than the ligament can support. They can also occur because of landing or awkward bending, such as if your foot stays in one place while your leg keeps moving.
Athletes in contact sports are the most likely to sustain an MCL injury. They are also common in those who have to squat and lift heavy objects, either for athletic training or in the course of their employment.
Common Symptoms of MCL Injuries
If you suffer an MCL injury in St. Clair, MO, you’ll likely notice the pain right away. Other symptoms may include:
- A sudden “pop” on the inside of your knee
- Feeling like the may buckle
- Pain or discomfort when trying to bear weight
- Contusions
- Tenderness where the MCL is located
- Inflammation, either on the inside of the knee or the entire knee joint
Sometimes your knee may feel like your knee is loose when you walk, even if walking doesn’t hurt, or in other cases the knee feels too stiff. Any time you feel pain or instability in your knee, do not participate in any more strenuous activity and schedule a physical examination in order to get a diagnosis.
Diagnosing and Treating an MCL Injury in St. Clair, MO
Diagnosing an MCL injury requires going to a physical examination. In the examination, your St. Clair, MO doctor or physical therapist will go over how the injury occurred, will feel for swelling and how your knee is different from your healthy knee, and perform a valgus stress test.
Most physical therapists or doctors with knowledge of movement health in St. Clair, MO will be able to determine if you have 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 magnet and computer-generated radio waves to take three-dimensional images of your soft tissue
- An ultrasound, which uses sound waves and can help determine how severely the ligament is torn
- An X-ray, which does not show soft tissue, to insure your femur, patella, tibia, and fibula have not been broken
Alternatively, you can visit the Axes location nearest you for a free, no-risk injury screening. While we will be able to diagnose your injury, Missouri law stipulates a prescription for further physical therapy.
How MCL Injuries are Treated in St. Clair, MO
Typically, treating an MCL injury begins with basic first aid: reducing swelling, relieving discomfort, and utilizing the R.I.C.E. Method of Rest, Ice, Compression, and Elevation. For grade 1 injuries, the R.I.C.E method, over-the-counter pain relievers, and some time spent off your feet may be all you need for your body to heal itself.
Professional physical therapy is needed for grade 2 and 3 injuries to restore strength and function and get you back to the activities you love. You’ll also need time resting to allow your body to heal safely. Your Axes physical therapist in St. Clair, MO will be able to fit you for a knee brace to give your knee stability while it’s healing. With physical therapy, you’ll still continue icing your knee and taking anti-inflammatory pain medication.
Surgery is typically only needed with severe grade 1 MCL injuries, or if the MCL tear is accompanied by an ACL tear or other damage to the structures of the knee. The surgery is carried out by using a graft, either from your hamstring or from another person, to reconstruct the ligament. You would not have to be hospitalized overnight. If you do require surgery in St. Clair, MO, our physical therapists are experts at pre- and post-surgical rehabilitation get you the best possible results from your surgery.
