Avoiding Surgery with Regenerative Medicine for LCL & MCL Tears
Understanding Lateral and Medial Collateral Ligament (LCL/MCL) Injuries
The knee is one of the most utilized and complex joints in the body, stabilized by a network of ligaments. Two of the most commonly injured are the medial collateral ligament (MCL) and the lateral collateral ligament (LCL). These ligaments provide side-to-side stability and are critical in supporting the knee during movement and weight-bearing.

What are MCL and LCL Tears?
The MCL runs along the inner aspect of the knee and resists forces that are pushing the knee inward. This ligament is usually injured more than the LCL, especially in contact sports or activities as they require some twisting movements.
The LCL is a lateral ligament. It prevents the knee from buckling outward. LCL injuries commonly occur from a direct blow to the inside of the knee.

Common Symptoms of an MCL or LCL Tear
- Pain along the inside (MCL) or outside (LCL) of the knee
- Swelling and stiffness
- Instability or feeling that the knee may give out
- Bruising around the affected site
- Difficulty walking or bending the knee
According to the American Academy of Orthopaedic Surgeons (AAOS), MCL injuries account for approximately 24% of all knee ligament injuries, while LCL injuries are less common but often more severe when they occur in combination with other ligament damage.

Conventional Treatment Options
The treatment course of MCL and LCL tears depends on the severity of each case:
- Grade I (Mild): Rest, Ice, Compression, Elevation (RICE), physical therapy
- Grade II (Moderate): Bracing and rehabilitation, sometimes corticosteroids injections
- Grade III (Severe or Complete Tear): May require surgical repair, especially in LCL injuries or when multiple ligaments are involved
Although conservative treatment is good for minor injuries, surgical treatment for ligament tears can result in complications like infection, long downtime, scar tissue accumulation, and incomplete healing.
Cutting-Edge Regenerative Treatment: Stem Cell, PRP, and Autologous Conditioned Serum Injections
Modern regenerative therapies offer powerful alternatives to surgery for ligament injuries. These include:
- Platelet-Rich Plasma (PRP)
PRP comes from the blood of the patient. Upon processing, the plasma will have concentrated levels of growth factors and cytokines that help in healing and tissue regeneration.
Benefits for LCL/MCL Tears:
Basically stimulates the body to heal itself, reduces pain and inflammation, leads to faster recovery when combined with physical therapy, and is particularly effective in partial tears and chronic ligament strains
- Stem Cell Therapy
Stem cells are powerful, undifferentiated cells capable of regenerating damaged tissues. At our clinic, we use:
- Fat-derived stem cells (Nano-fat, Stromal Vascular Fraction)
- Bone marrow aspiration-derived stem cells
- Umbilical cord-derived mesenchymal stem cells
How They Work:
Stem cells not only hone in on damaged tissue but they differentiate into ligament cells and promote collagen remodeling. They also release anti-inflammatory molecules and growth factors to the affected area.
- Autologous Conditioned Serum (ACS)
Also known as *Regenokine or *Orthokine. ACS is prepared by drawing blood from the patient and incubating it for several hours. This leads to the production of anti-inflammatory proteins, principally interleukin-1 receptor antagonists (IL-1Ra).
Benefits:
- Powerfully reduces inflammation
- Helps relieve pain and promote tissue healing
- Is used frequently for injuries sustained by elite-level athletes

Frequently Asked Questions (FAQ)
-
Yes. For many patients, particularly those with partial or moderate ligament injuries, regenerative injections like PRP, stem cells, and ACS can significantly improve healing, stability, and pain, often eliminating the need for surgery.
-
Injections are guided using advanced ultrasound or fluoroscopy (X-ray), ensuring pinpoint accuracy to the injured ligament. This improves safety and outcomes.
-
Discomfort is minimal and usually resolves within a day. Dr. Nourparvar uses precise, minimally invasive techniques.
-
Yes. These are autologous or ethically sourced biological treatments with an extremely low risk for adverse effects.
-
Many athletes return to full activity post-regenerative treatment, often faster than surgical routes.
