Chronic subluxation of the patella is a condition that occurs when the kneecap slides out of its normal position and partially dislocates repeatedly over time. This condition is also known as recurrent patellar subluxation or patellar instability. It can be a painful and frustrating condition, and if left untreated, it can lead to long-term joint damage and arthritis. In this blog, we will discuss the causes, symptoms, and treatment options for chronic subluxation of the patella.

Causes:

Chronic subluxation of the patella can be caused by several factors, including:

1. Muscular imbalance: Weakness or tightness in the muscles that surround the knee joint can affect the alignment of the patella, leading to subluxation.

2. Anatomical abnormalities: Certain anatomical abnormalities such as a shallow groove on the femur, a high-riding patella, or a malaligned tibia can contribute to the development of chronic patellar subluxation.

3. Trauma: A traumatic injury to the knee can damage the soft tissues that hold the patella in place, leading to instability.

4. Overuse: Repeated stress on the knee joint, such as in athletes who participate in activities like jumping or running, can cause chronic subluxation of the patella.

Symptoms:

The most common symptoms of chronic subluxation of the patella include:

1. A feeling of the knee giving way or buckling

2. Pain and tenderness around the kneecap

3. Swelling and stiffness in the knee joint

4. Difficulty straightening or bending the knee

5. A popping or grinding sensation when moving the knee joint

Treatment:

The treatment for chronic subluxation of the patella depends on the severity of the condition and the underlying cause. Treatment options may include:

1. Non-surgical treatment: Non-surgical treatment options for chronic subluxation of the patella may include physical therapy, which can help to strengthen the muscles around the knee joint, and bracing or taping, which can provide additional support and stability to the joint.

2. Surgical treatment: In cases where non-surgical treatment options are not effective, surgery may be necessary. Surgical options for chronic subluxation of the patella may include lateral release, which involves releasing the tight structures on the outside of the knee, or medial patellofemoral ligament (MPFL) reconstruction, which involves reconstructing the ligament that stabilizes the patella.

3. Lifestyle modifications: Making certain lifestyle modifications, such as avoiding activities that put undue stress on the knee joint and maintaining a healthy weight, can also help to reduce the symptoms of chronic subluxation of the patella.

Conclusion:

Chronic subluxation of the patella is a condition that can cause significant pain and discomfort in young adults. If you experience any of the symptoms associated with this condition, it is important to seek medical attention to determine the underlying cause and receive appropriate treatment. With proper treatment and care, it is possible to manage the symptoms of chronic subluxation of the patella and improve your quality of life.
