MCL Tears

The medial collateral ligament (MCL) is a strong ligament on the inside of your knee.  It is primarily responsible for the side-to-side stability of the knee.  It is often injured with impact injuries to the knee.  The MCL has a better blood supply than most ligaments in the knee and therefore a better healing potential. Stress X-Rays will determine how badly the MCL is injured.  Ligament injuries are graded as grade 1- sprain without instability to grade 3- complete tear.

Non-Surgical Treatment

The MCL can often be treated without surgery.  The mainstay of treatment is protecting the MCL with a brace.  You will also be held out of sports and may even need crutches of you have other injuries.  Physical therapy will be a mainstay of your treatment.

Surgical Treatment

Surgery is reserved for certain instances only.  Dr. Petre will need to examine you and evaluate your x-rays and MRIs in order to be able to tell you if you need surgery.  Some of the instances that need surgery are tears of the MCL that come off of the tibia, tears that are associated with other knee ligament tears, or severe complete tears.  Surgery may be a ligament repair with suture anchors or a ligament reconstruction with a donor graft.  Patients who need surgery will need a brace after surgery and physical therapy for strengthening and motion.

Recovery and Rehabilitation

On average, a ligament takes 6 weeks to heal.  Whether you need surgery or non-surgical treatment, you should expect to be wearing a brace and possibly modifying your activity for at least this long.  Some Grade 1-2 injuries can return to sports before 6 weeks with the brace on.
