An MCL sprain is a tear.
MCL Sprain Diagnosis:
Such sprains are graded according to the severity of the injury:
Grade I: The ligament has microscopic tears, but the joint is still stable.
Grade II: The ligament has been partially torn and there is a certain amount of instability in the joint.
Grade III: The ligament has been completely ruptured, either in the middle of the ligament, or torn away from one of the attachments to bone and the knee joint is completely unstable.
