MCL repair surgery is extremely rare. See your physician to discuss options appropriate for your age and level of activity. Depending on desired level of activity and degree of involvement in sports, non-operative management may be adequate. Surgical options for this injury are multiple. An MRI examination may be required to diagnose the presence of other injuries like meniscal tears or other ligament injuries within the knee as well as any possible damage to the smooth cartilage surfaces within your knee.
Steps you can take to try to prevent MCL injury, as well as other knee injuries, include proper stretching before and after exercise and using safety equipment when appropriate. Avoiding activities that put sideways strain upon your knee will also help you avoid an MCL injury. Building up the muscles in the thigh may also help to stabilize the knee and can help decrease your risk of injury.
