What Are the MCL and PCL?

The medial collateral ligament (MCL) and posterior cruciate ligament (PCL) are two of the four major knee ligaments that stabilize the knee joint:

  • The MCL is located on the inner side of the knee and connects the thigh bone (femur) to the shin bone (tibia). It prevents excessive side-to-side movement.
  • The PCL is found at the back of the knee and works with the anterior cruciate ligament (ACL) to control backward motion of the shin bone.
 

Both ligaments play a crucial role in knee stability and function, and an injury to either can significantly impact mobility. Other ligaments in the knee include the lateral collateral ligament (LCL) and the anterior cruciate ligament (ACL).

What Are MCL and PCL Injuries?

An MCL injury occurs when the ligament is overstretched or torn due to excessive force on the outside of the knee. MCL tears are common in contact sports.

PCL injuries are less common but can be just as serious. A posterior cruciate ligament injury typically happens due to direct impact to the knee when it’s bent, such as in car accidents or falls. 

Both types of injuries can range from mild sprains to complete ligament tears, affecting knee stability and function.

What Are the Causes of MCL and PCL Injuries?

Several factors can lead to MCL and PCL injuries, including:

  • Direct Impact: A hard hit to the knee from the front or side, common in football, soccer, and basketball.
  • Twisting Motions: Sudden changes in direction or pivoting, especially with a bent knee, can stress the ligaments.
  • Falls & Accidents: Landing awkwardly on the knee or experiencing trauma, such as a dashboard impact in a car accident.
  • Weak Ligaments: Individuals with prior knee injuries may be more prone to ligament damage.

Symptoms of a PCL or MCL Injury

A ligament injury in the knee often presents with noticeable symptoms, including:

  • Pain and Swelling: Immediate or delayed swelling in the knee joint.
  • Instability: A feeling of the knee “giving out” or being unable to bear weight.
  • Limited Range of Motion: Difficulty fully straightening or bending the knee.
  • Tenderness: Pain when pressing on the inner knee (MCL) or the back of the knee (PCL).
  • Bruising: In more severe posterior cruciate ligament injuries, bruising may appear behind the knee.
 

If you experience these symptoms, it’s crucial to seek medical evaluation to prevent further damage.

How Are MCL & PCL Injuries Diagnosed?

A proper diagnosis is essential for determining the severity of MCL and PCL injuries. Dr. Szerlip uses a combination of the following diagnostic methods:

  • Physical Examination: Assessing knee stability, pain, and range of motion.
  • Imaging Tests: X-rays rule out fractures, while MRIs provide detailed images of ligament damage.
 

A thorough diagnosis ensures that you receive the most effective treatment plan.

How Are MCL and PCL Tears Treated?

Treatment for MCL and PCL tears depends on the severity of the injury:

Non-Surgical Treatment

Non-surgical treatments may include the following:

  • Rest and Ice: Reducing inflammation and allowing healing.
  • Knee Brace: Providing support while the ligament heals.
  • Physical Therapy: Strengthening surrounding muscles to improve stability.

Surgical Treatment

Severe knee ligament injuries, such as a complete posterior cruciate ligament (PCL) tear, may require surgery to restore function. Dr. Szerlip specializes in advanced knee reconstruction techniques to ensure optimal recovery.

Recovery from MCL and PCL Injuries

Recovery time varies based on injury severity:

  • Mild Sprains: 2-4 weeks with rest and rehabilitation.
  • Partial Tears: 4-8 weeks with bracing and physical therapy.
  • Complete Tears: 3-6 months or longer if surgery is required.
 

Following a structured physical therapy program is essential for regaining full knee strength and mobility. Benjamin W. Szerlip, DO, provides personalized rehabilitation plans to help you return to your activities safely.
