MCL Tear and Repair Treatment
The medial collateral ligament — or MCL — is the most commonly injured ligament in the knee, running along the inner side of the joint from the femur to the tibia and serving as the primary restraint against forces that push the knee inward. MCL injuries most frequently result from a direct blow to the outside of the knee — the classic “clipping” mechanism in football — but they can also occur during non-contact pivoting, skiing falls, or any movement that forces the knee into a valgus (inward-opening) position. The severity ranges from a mild stretch with intact fibers to a complete rupture that compromises medial knee stability. Unlike the ACL, the MCL has a robust blood supply and reliable healing capacity, which means the great majority of MCL injuries respond well to non-surgical treatment. However, severe tears — particularly those involving multiple structures on the medial side of the knee or occurring in combination with ACL or meniscus injuries — may require surgical repair or reconstruction to restore full stability.
Dr. Jonathan Glashow is a board-certified orthopedic surgeon and Clinical Associate Professor of Orthopedic Surgery at NYU Grossman School of Medicine, with over 30 years of specialized experience in knee ligament diagnosis and treatment. His published research in the Journal of Bone and Joint Surgery on ACL and meniscal lesion diagnosis has directly informed the clinical standards used to evaluate ligament injuries — including the multi-ligament combinations that commonly accompany severe MCL tears. As Chief Medical Officer for the New Jersey Devils and Philadelphia 76ers, he manages MCL injuries in professional athletes across two of the most physically demanding sports in the world, where the decision between conservative management and surgical intervention has direct implications for career longevity and competitive performance. Named a Castle Connolly Top Doctor every year since 2000, Dr. Glashow evaluates MCL tears with same-day imaging at his Upper East Side practice in New York City.
Diagnosis and Treatment of MCL Injuries
Early treatment of MCL injuries involves rest, ice, anti-inflammatory medications, rehabilitation exercises and/or the use of a brace. More severe tears may require the use of crutches for several weeks until the pain subsides, followed by range-of-motion exercises. Surgery may be required depending on the result of your injury.
The most common knee ligament injury is an injury to the medial aspect of the knee. There are three main anatomic structures on the medial side of the knee, with the medial collateral ligament (MCL) being the largest and strongest. A significant amount of isolated MCL medial knee injuries are due to sports injuries. They can be either a contact or non-contact stress to the outside of their knee, which in turn stretches or tears the medial knee structures on the inside of the knee.
The medial collateral ligament (MCL) is one of four ligaments that are essential to the stability of the knee joint. Located on the inside of the knee joint, the MCL spans from the lower tip of the thigh bone (femur) to the top of the shin bone (tibia). The MCL prevents over-widening of the inside of the knee joint.
Causes of an MCL Injury
- Most MCL injuries result from a direct blow to the outside of the knee (as in “clipping” in football), which causes the outside of the joint to buckle and the inside to widen. This causes the MCL to over-stretch, which can result in injury or tearing. Other ligaments, including the ACL or the meniscus, are sometimes torn at the same time as the MCL.
Symptoms of an MCL Injury
- Pain, swelling and bruising directly over the ligament
- Instability or buckling of the knee joint
Treatment Options for MCL Repair in NYC
Options available for medial collateral (MCL) repair and reconstruction include the following:
- Distal advancement
- Proximal advancement
- Direct repair
- Augmentation
- Medial imbrication
Large MCL tears may require surgery and physical therapy. Knee ligament repair is a treatment for a complete tear of a knee ligament that results in instability in the knee. Our best in class NYC orthopedic surgeons combine arthroscopic MCL surgery with aggressive rehabilitation to get you back to your life as quickly as possible.
If you have sustained a blow to the outside of your knee, are experiencing pain and swelling on the inner side of the joint, or have been diagnosed with an MCL tear and want to discuss your treatment options, Dr. Glashow provides same-day evaluation with on-site imaging at his Upper East Side practice.

Frequently Asked Questions About MCL Tears
How do I know if I tore my MCL?
An MCL tear typically produces immediate pain on the inner side of the knee, swelling and bruising along the medial joint line, and a feeling that the knee is opening up or giving way when force is applied to the outer side. You may hear or feel a pop at the time of injury. Grade 1 sprains cause tenderness but the knee feels stable, grade 2 partial tears produce more significant swelling and mild instability, and grade 3 complete tears result in substantial looseness on the inner side of the joint. Dr. Glashow uses the valgus stress test — applying gentle inward force to the knee at both full extension and 30 degrees of flexion — along with MRI to confirm the grade of injury and identify any associated damage to the ACL, meniscus, or other structures.
Can an MCL tear heal without surgery?
Yes — and the majority do. The MCL has a better blood supply and more reliable self-healing capacity than the other major knee ligaments. Most grade 1 and grade 2 MCL injuries, and even many isolated grade 3 tears, heal successfully with a structured non-operative protocol that includes bracing, rest, anti-inflammatory medications, and progressive physical therapy. Surgery is typically reserved for MCL tears that do not heal with conservative treatment, tears involving the deep medial structures that create persistent instability, and combined injuries where the MCL tear is accompanied by an ACL rupture or significant meniscus damage that also requires surgical intervention.
What is the difference between MCL repair and MCL reconstruction?
MCL repair involves directly reattaching or reapproximating the torn ends of the ligament — often with suture anchors — and is most effective for acute tears where the tissue quality is still good. MCL reconstruction replaces the damaged ligament with a tendon graft when the native tissue is too stretched, retracted, or degenerated to hold a repair. Dr. Glashow also offers techniques including distal advancement, proximal advancement, augmentation, and medial imbrication — selecting the approach that best matches the specific tear pattern and the patient’s functional demands.
Are MCL tears often combined with other knee injuries?
Yes. MCL tears frequently occur alongside other ligament injuries — most commonly ACL tears, which can happen simultaneously when a valgus force is combined with a rotational component. The combination of ACL and MCL tears is one of the most common multi-ligament knee injury patterns in contact sports. MCL tears can also be associated with meniscus damage, particularly to the medial meniscus. Dr. Glashow evaluates each injury with a comprehensive clinical examination and MRI to identify the full scope of damage before developing a treatment plan.
How long does recovery take after an MCL injury?
Recovery timelines depend on the grade of the tear and whether surgery was required. Grade 1 sprains typically heal within one to three weeks. Grade 2 partial tears generally require three to six weeks before returning to full activity. Grade 3 tears treated non-operatively may take six to eight weeks with bracing and rehabilitation. Surgical MCL repair or reconstruction requires a longer recovery — typically three to six months — with a structured physical therapy program progressing through range of motion, strengthening, and sport-specific training. Dr. Glashow coordinates rehabilitation closely with physical therapists and provides each patient with a specific return-to-activity timeline based on their injury pattern and healing progress.
Can I prevent MCL injuries?
While contact injuries to the outside of the knee are difficult to prevent entirely, several strategies can reduce risk. Strengthening the muscles around the knee — particularly the quadriceps, hamstrings, and hip stabilizers — provides dynamic support to the medial structures. Neuromuscular training programs that improve balance, landing mechanics, and cutting technique have been shown to reduce ligament injury rates in athletes. Proper warm-up before activity, sport-appropriate bracing for athletes in high-risk positions, and maintaining overall lower-extremity conditioning also contribute to protecting the MCL.
