MCL injuries normally happen when the knee is forced inwards into an excessive ‘knock knee’ position. This may be because the outside of the knee is struck or because the foot is caught and the knee is forced sideways. An MCL injury can vary from a mild tear to a full tear of the ligament. This type of injury is more common in children and teenagers.
A diagnosis made during a medical examination can be backed up with X-rays and an MRI scan to show the extent of the damage.
Most MCL injuries heal without surgery. Using a hinged knee brace for around six weeks will prevent excessive sideways movement and allow the MCL to heal naturally without being overstretched. This, together with physiotherapy, is often the only treatment required. Surgery is usually only necessary for professional athletes or where there is a long term (chronic) MCL tear associated with an ACL injury.
