What is a Sprained Knee?

A sprained knee occurs when one or more of the knee ligaments are stretched or torn due to injury. The knee joint relies on four primary ligaments to maintain stability and proper movement:

  • Anterior cruciate ligament (ACL): Controls forward movement and rotation of the knee.
  • Posterior cruciate ligament (PCL): Supports backward movement of the knee.
  • Medial collateral ligament (MCL): Provides stability on the inner side of the knee.
  • Lateral collateral ligament (LCL): Maintains stability on the outer side of the knee.
 

When these ligaments are damaged, it can result in mild to severe knee strain, depending on the extent of the injury.

What Are Knee Sprain Symptoms?

The symptoms of a knee sprain vary depending on the severity of the injury. Common knee sprain symptoms include:

  • Swelling around the knee joint
  • Pain or tenderness in the injured knee
  • Difficulty bearing weight on the leg
  • Bruising or discoloration
  • A popping sensation at the time of injury (often seen with ACL or PCL injuries)
  • Limited range of motion or stiffness
 

Severe sprains or a torn ligament may cause instability, where the knee feels like it might give out during movement.

What Causes Knee Sprains?

A knee sprain often results from sudden movements or trauma that strain the knee ligaments. Common causes include:

  • Sports injuries involving twisting or pivoting, especially in activities like basketball, soccer, or skiing.
  • Falls that force the knee into an unnatural position.
  • Direct impact to the knee joint, such as a collision during contact sports.
  • Hyperextension or overuse injuries.
 

Poor conditioning of leg muscles or weak knee ligaments can increase the risk of sprains, especially during intense physical activity.

How Are Knee Sprains Diagnosed?

Diagnosing a knee sprain begins with a physical examination. A fellowship-trained sports medicine surgeon like Dr. Benjamin Szerlip will evaluate your injured knee by checking for swelling, range of motion, and ligament stability.

Imaging tests such as X-rays or an MRI may be recommended to confirm the diagnosis and determine the severity of the sprain. An MRI is especially helpful for assessing damage to the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), or other collateral ligaments

What Treatments Are Available for a Sprained Knee?

Treatment for a knee sprain depends on its severity. Here are the most common approaches:

Rest, Ice, Compression, and Elevation (RICE)

This initial treatment is essential for reducing swelling and alleviating knee pain. Using an elastic bandage or wrap can provide gentle compression to support the knee.

Medications

Over-the-counter pain relievers like ibuprofen can help manage swelling and discomfort.

Knee Brace or Support

A knee brace may be recommended to stabilize the knee joint and prevent further injury during recovery.

Physical Therapy

Physical therapy plays a crucial role in regaining strength and mobility. Therapists design exercises to strengthen leg muscles, improve flexibility, and prevent long-term complications.

Surgical Intervention

For severe sprains, such as a completely torn ligament, surgery may be necessary. Procedures like ligament reconstruction can restore knee stability. Dr. Szerlip specializes in minimally invasive surgical techniques for ligament injuries, ensuring optimal recovery outcomes.

Recovery From a Knee Sprain

Recovery time varies based on the severity of the sprain:

  • Mild sprains: Typically heal within 2-4 weeks with proper care.
  • Moderate sprains: May require 4-6 weeks of rehabilitation.
  • Severe sprains: Recovery can take several months, especially after surgery.
 

Adhering to your physical therapy plan and gradually reintroducing activity are critical steps in the healing process. Regular follow-up visits with Dr. Szerlip ensure your knee is healing correctly and prevent setbacks.

Can Knee Sprains Be Prevented?

While it’s impossible to prevent all knee injuries, these tips can reduce your risk of a sprained knee:

  • Strengthen your leg muscles to support the knee joint.
  • Stretch regularly to improve flexibility and reduce stiffness.
  • Wear proper footwear during physical activities.
  • Use protective gear, like knee pads or braces, in high-impact sports.
  • Practice proper technique when running, jumping, or pivoting.
 

If you’ve had previous knee injuries, working with a sports medicine surgeon can help develop a prevention plan tailored to your needs.
