How can I tell if I injured my medial collateral ligament (MCL)?

National Athletic Trainers' Association

A sprain of the medial collateral ligament (MCL) is characterized by pain on the inside of the knee, decreased ability to straighten and bend the knee, possible decrease in knee strength, and possible feeling of the knee being loose. It is common to also have symptoms of a meniscus tear or anterior cruciate (ACL) sprain with this injury.

Muscle & Connective Tissue Injuries

Muscle and connective tissue injuries include sprains and strains, which are the most common injuries for people engaged in physical sports. A sprain is an injury of a ligament, which connects our bones to each other. A strain is an injury that can occur to a muscle or a tendon, which connects our bones to our muscles. If you have a muscle or connective tissue injury, you will likely experience pain, swelling, and limited movement of that body part. Sometimes these injuries are evident as soon as they occur, while others take time to develop. Usually rest helps to heal the area, and ice can reduce swelling. If these remedies dont help you, physical therapy or surgery may be necessary for a full recovery.
