Anterior Cruciate Ligament (ACL) injury:
Medical Definition: Tearing of the ACL. The ACL is a ligament that connects the tibia to the femur and is necessary to help stabilize the knee joint area.
Causes: ACL injuries may occur in many different situations but are often caused by a sudden hit to the knee or a pivoting (change in direction) injury.
Symptoms: Pain (will vary depending on injury severity) and swelling. Instability to the knee joint area.
Recommended Treatment: ACL injuries demand immediate medical attention. Depending upon the severity of the injury, surgery may be required. Range of motion exercises, ice and physical therapy are recommended before and after surgery (if required).
Medial Collateral Ligament (MCL) injury:
Medical Definition: Tear to the medial collateral ligament. The MCL is located on the inside of the knee, while the lateral collateral ligament(LCL) is located on the outside of the knee. Injury to the MCL is more common than injury to the LCL.
Causes: Twisting injury to the knee or a blow to the outside of the knee, often occurring in sports.
Symptoms: Pain and swelling. Requires evaluation by a medical professional.
Recommended Treatment: Follow advice from a medical professional. MCL injuries are usually not as serious as a ACL injury.
