What Happens During Arthroscopic MCL Reconstruction?

In arthroscopic MCL reconstruction, the surgeon makes small incisions and uses a camera to remove the damaged medial collateral ligament. After that, they replace the ligament with a graft taken from your hamstring tendons or donor tissue. The new graft is then secured with anchors or screws to restore knee joint stability.

At Total Orthopedics and Sports Medicine, our board-certified orthopedic knee surgeons are highly experienced in minimally invasive ligament injury procedures, including MCL surgery. We use advanced arthroscopic tools and evidence-based protocols to ensure accurate graft placement and faster recovery from knee pain.

How Is Arthroscopic MCL Reconstruction Performed?

Surgeons perform medial collateral ligament reconstruction by making small incisions around your knee and inserting a camera to view the knee joint. They remove the damaged ligament and replace it with a patellar tendon graft taken from the patient’s hamstring tendons. Then they fix the graft to the thigh bone and shin bone using screws.

Here are the steps surgeons take to perform MCL reconstruction surgery:

1. The surgery begins with a thorough physical examination and imaging to assess the extent of the MCL tear.
2. Small incisions are made to insert the arthroscope and instruments.
3. The surgeon creates tunnels in the femur (or thigh bone) and shin bone to properly anchor the graft.
4. Lastly, the surgeon secures the tendon with medical-grade anchors to replicate the native MCL’s function and restore joint stability.

This approach minimizes damage to surrounding tissues, shortens recovery time, and often results in a shorter hospital stay. A systematic review in ScienceDirect compared MCL repair versus reconstruction in patients with at least two years of follow-up. The result shows that medial collateral ligament reconstruction is a reliable choice, particularly in cases where nonsurgical treatment options fail. However, most MCL tears heal without surgery; a complete tear involving the medial or lateral compartments may require surgery.

How Can You Prepare for MCL Reconstruction Surgery?

To prepare for MCL reconstruction surgery, you should follow your surgeon’s instructions and arrange support after the outpatient procedure. You should also avoid NSAIDs and blood thinners to prevent blood loss. Also, engage in prehabilitation exercises and avoid chronic disease risk factors, which help with healing.

To ensure a smooth surgery and recovery, you can also follow these tips:

1. Schedule a detailed medical checkup to reduce the risk of degenerative changes.
2. Avoid eating or drinking before receiving general anesthesia.
3. Address lifestyle factors such as smoking or any active infection early to prevent complications.
4. Limit weight-bearing activities, knee flexion, and external rotation activities during recovery.
5. Get imaging tests to determine the severity of the torn ligament or the necessity of MCL augmentation.

NCBI research shows that doctors use MRI to determine whether the MCL is ruptured and pinpoint the exact location of the injury. Moreover, it also reveals any associated ligament, soft tissue, or bone damage. These findings help us determine the most appropriate initial treatment approach during the acute phase of an MCL injury.

What Types of Grafts Are Used in MCL Reconstruction?

Surgeons typically use autografts (the patient’s tissue) or allografts (donor tissue) in medial collateral ligament reconstruction. Common graft sources include the hamstring tendon, patellar tendon, or quadriceps tendon, depending on the patient’s anatomy, injury severity, and recovery goals.

Doctors often prefer autografts for younger athletes because they carry a lower risk of immune response. In contrast, allografts are ideal for patients dealing with multiple ligament injuries, such as an ACL injury. Each graft is secured using strong sutures to ensure proper fixation, especially in cases involving knee instability or complex trauma. Moreover, the choice of graft also helps stabilize the joint and address ligament instability, particularly in athletes with combined ACL and MCL damage.

At Total Orthopedics and Sports Medicine, our expert MCL reconstruction surgeons specialize in minimally invasive, arthroscopic procedures. We assess the extent of the injury through advanced diagnostics and use the most appropriate graft to restore complete knee function.

Which Imaging Tests Are Used to Diagnose MCL Injuries?

Doctors typically use MRI scans, X-rays, and ultrasound to diagnose knee injuries such as MCL tears. MRI provides detailed images of soft tissue and major ligaments. However, X-rays help diagnose fractures, and ultrasound may detect torn ligaments in real time during movement.

Doctors also consider MRI the gold standard for diagnosing medial collateral ligament injuries. It provides detailed images of the main ligaments and helps them assess whether the ligament is partially or completely torn. According to a Springer review, 808 injured people show that MRI and ultrasound are highly reliable in diagnosing MCL injuries. Although MRI shows 65–92% greater sensitivity compared to physical exams, it still misses ligament instability in up to 21% of cases and may not always accurately locate the lesion site.

How Is Knee Pain Managed After MCL Reconstruction?

You can manage knee pain after MCL reconstruction by taking your prescribed pain medications, using cryotherapy, keeping your leg elevated, and limiting weight-bearing activities. Also, you can start targeted therapy early to reduce inflammation, improve mobility, and avoid long-term stiffness and discomfort.

After surgery, follow these tips to reduce pain:

• Wear a hinged knee brace to protect the ligament and stabilize the joint
• Use ice packs regularly during the initial days to reduce swelling
• Take NSAIDs or doctor-prescribed analgesics to control pain

According to Medrxiv’s study, doing proprioceptive neuromuscular facilitation (PNF) training after MCL reconstruction helped patients reduce pain and improve movement. However, it’s essential to avoid certain twisting movements or combined force impacts, especially in the early 0/2–4 weeks post-op, as these can delay healing and increase the risk of reinjury.

How Does MCL Reconstruction Differ From Open Surgery?

MCL reconstruction is usually done arthroscopically, using small incisions and a tiny camera to repair the ligament precisely. This approach reduces tissue damage, speeds up recovery, and improves scarring. In contrast, open surgery requires larger cuts and more invasive methods, often resulting in longer rehabilitation.

Arthroscopic MCL reconstruction allows surgeons to repair the damaged medial collateral ligament using a graft. This minimally invasive method is ideal for isolated MCL tears or combined ligament injuries. However, in more severe cases, such as those involving joint misalignment or an associated ACL injury, open surgery may be required. This approach provides direct access to deeper structures but involves larger incisions and a longer rehabilitation period. However, the choice between these surgeries depends on the severity of the injury, patient activity level, and knee stability.

How Soon Can You Return to Routine Activities After an MCL Tear?

You can usually return to routine activities within 2 to 6 weeks after an MCL tear, depending on the severity. Mild sprains heal quickly, while complete tears may take 6 to 12 weeks or longer to recover, especially if you need surgery.

However, the recovery timeline depends on the severity or grade of the MCL tear, as outlined below:

• Grade 1 (mild): MCL sprains often allow a return to light activities within 2–3 weeks.
• Grade 2 (moderate): It may need 3–6 weeks with a structured rehabilitation routine.
• Grade 3 (complete): Severe tears involving combined force impacts or additional ligament damage often require surgical repair and may take 12 weeks or more for full recovery.

While these timelines may vary depending on the patient’s situation, it’s important to avoid weight-bearing activities as they may increase the risk of knee stiffness or reinjury. Also, make sure to consult Total Orthopedics and Sports Medicine doctors to get supervised exercise sessions and better recovery plans.

What Are the Signs That MCL Surgery Has Failed?

If you’re experiencing persistent knee pain, ongoing instability, limited range of motion, swelling, and difficulty bearing weight, it shows that MCL surgery has failed. Even if your knee feels weak or you can’t handle twisting movements, it means the surgery didn’t succeed. Besides this, other red flags include persistent knee stiffness or a popping sensation when walking or bending. A failed MCL repair happens mostly due to poor graft healing, infection, or combined force impacts that re-injure the area. Therefore, if you’re unsure, consult your surgeon for a detailed exam or imaging to assess the ligament and decide the next steps.
