Patellar Dislocation in Athletes: A Hidden Threat to Knee Stability

Patellar dislocation occurs when the kneecap, or patella, shifts out of its groove in the femur. This can cause pain, instability, and difficulty moving the knee. Although it’s a serious threat to knee stability, patellar dislocation is a lesser-known sports injury.

At Advanced Orthopaedic Associates, our sports medicine experts understand patellar dislocation and its solutions, and we’re here to help you do the same while reclaiming your active life. Here’s what you need to know about this hidden threat to knee stability.

Understanding Patellar Dislocation

Traumatic patellar dislocation occurs when the kneecap moves completely out of its usual position. This injury typically happens during a fall or sports accident. Athletes who play high-impact sports and those who pivot frequently have a higher risk of patellar dislocation. Women and larger men also have a higher risk of traumatic patellar dislocation.

Chronic patellar instability occurs when the kneecap frequently slides partially out of place. It means you can’t rely on your knee anymore, as it could unexpectedly feel like it’s giving out at any moment. Chronic patellar instability is fairly common following a traumatic patellar dislocation, especially if you don’t seek treatment. Some studies estimate that the recurrence rate of patellar dislocation is up to 60%.

Signs of Traumatic Patellar Dislocation

Patients with a dislocated patella may hear a popping sound at the time of injury. Common symptoms include: 

• Pain 
• Swelling 
• Stiffness
• Weakness
• Bruising
• Difficulty Bearing Weight 
• Visible Deformity 

With chronic patellar instability, symptoms may be less severe because the kneecap isn’t fully out of place again. However, chronic patellar instability can still dramatically disrupt daily life and make it difficult to do the things you enjoy. 

Diagnosing and Treating Patellar Dislocation

Our sports medicine specialists use a comprehensive approach to diagnose patellar dislocation. Along with a full medical history and physical exam, we may order imaging, such as X-rays, to check specific measurements of the patellar tendon, including its position and angle. 

We may also order a magnetic resonance imaging (MRI) scan, which allows our team to assess the soft tissues in your knee, particularly the medial patellofemoral ligament (MPFL) that helps keep your patella stable. 

We combine advanced techniques with compassionate care to effectively resolve patellar dislocation. From conservative strategies like rest, bracing, and physical therapy to advanced ligament reconstruction, our specialists tailor a personalized approach to stabilize your patella and restore your quality of life.
