An unstable kneecap can cause pain, limit movement, and lead to recurring injuries. If you’ve experienced a kneecap that slips out of place or feels unstable, you may be dealing with patellar instability—a condition that can worsen without proper care.
Benjamin W. Szerlip, DO—a fellowship-trained sports medicine surgeon in Austin, Texas—specializes in diagnosing and treating knee conditions, including patellar instability. Whether you’re dealing with a first-time patellar dislocation or struggling with recurrent instability, we provide expert care to help you regain stability and prevent future injuries.

“Dr. Szerlip was very personable, knowledgeable, and took time for all my questions. He gave great explanations of my problem and potential solutions. I have full confidence in his recommendations for treatment and therapy.” — Pam G.
The kneecap (patella) moves within a groove on the thighbone called the trochlear groove. When this movement is disrupted, the kneecap may shift too far to one side or completely dislocate. This condition, known as patellar instability, can lead to pain, weakness, and difficulty moving the knee.
Patellar instability can occur suddenly from an injury or develop over time due to anatomical factors. If left untreated, it may increase the risk of long-term joint damage and arthritis.
The symptoms of patellar instability can vary depending on the severity of the condition. Common signs include:
If you experience these symptoms, it’s essential to seek evaluation from a qualified specialist like Dr. Szerlip to prevent further damage and ensure proper treatment.
Several factors can contribute to patellofemoral instability, including:
A direct blow to the knee, such as a fall or sports injury, can force the kneecap out of place, leading to a patellar dislocation.
Some people have naturally shallow trochlear grooves, making it easier for the kneecap to slip out of position. Others may have a misaligned tibial tubercle—the area where the patellar tendon attaches—causing abnormal tracking of the kneecap.
The medial patellofemoral ligament (MPFL) helps stabilize the kneecap. If this ligament is stretched or torn, it increases the risk of recurrent instability.
Weak quadriceps or tight ligaments can lead to improper kneecap movement, making dislocations more likely.
Women and individuals with a family history of patellar instability are more prone to this condition due to differences in hip and knee anatomy.
A thorough evaluation by a specialist is crucial for diagnosing patellar instability. Dr. Szerlip uses a combination of:
Early diagnosis allows for targeted treatment to prevent worsening instability and long-term knee damage.
Treatment for patellar instability depends on the severity of the condition. If dislocation occurs, the first step is to put the kneecap back in place in a procedure called reduction. Following reduction, Dr. Szerlip will offer either non-surgical or surgical options to restore knee stability, depending on whether it was the first time or a recurrent injury.
If a patellar dislocation occurs for the first time, the following non-surgical treatments may be offered:
For those with recurrent instability or severe structural issues, surgery may be necessary. Common procedures include:
Dr. Szerlip tailors treatment plans to each patient, ensuring the best approach for long-term knee stability.
While some risk factors are genetic, there are ways to reduce the risk of patellar dislocations and instability:
For athletes or individuals at higher risk, a consultation with Dr. Szerlip can provide personalized guidance on preventing knee instability.
The time it takes to recover from a dislocated kneecap depends on the severity of the injury and the type of treatment received. For a first-time patellar dislocation without significant damage, the recovery outlook is generally positive. Most individuals can return to their usual daily activities within six to eight weeks, while a full return to sports typically takes three to four months.
However, if you experience recurrent dislocations or require surgery due to severe damage, the healing process will take longer. In some cases, it may take a year or more before you’re able to resume high-impact activities or competitive sports.
Dr. Szerlip provides comprehensive post-treatment care, ensuring a safe and effective recovery for his patients.
