Rupture of the medial collateral ligament (MCL) of the knee is a traumatic injury that can occur as a result of a direct blow to the outside of the knee, or from a sudden twisting of the knee joint.
The diagnosis of an MCL rupture is typically made through physical examination and imaging tests such as X-ray, MRI, or CT scan.
Differential diagnoses for MCL rupture include other knee ligament injuries, such as an ACL rupture, as well as meniscal tears.
Treatment for an MCL rupture depends on the severity of the injury. Non-surgical treatment may involve bracing and physical therapy, while surgical treatment may involve repair or reconstruction of the ligament.
The prognosis for an MCL rupture is generally good with appropriate treatment. Recovery times vary depending on the severity of the injury, but full recovery is usually expected.
