Kneecap Dislocation: Causes, Symptoms, and Treatment
Introduction
Kneecap dislocation, also known as patellar dislocation, is a common problem among young individuals. The kneecap, or patella, is a small bone in front of the knee joint that plays a crucial role in knee bending and straightening. In this blog, we will explore the causes, symptoms, and treatment options for kneecap dislocation.
Anatomy of the Kneecap
The kneecap is located just under the skin and rests in a shallow groove on the thigh bone. It is not the main bone of the knee joint, which consists of the thigh bone and the shin bone. However, the kneecap is essential for proper knee bending and straightening. As the knee moves from a straight position to a bent position, the kneecap follows along the femur bone.
Causes of Kneecap Dislocation
Kneecap dislocation can occur due to various factors, including injuries, twisting movements, and sports-related incidents. Even minor injuries can lead to kneecap dislocation.
Symptoms of Kneecap Dislocation
When the kneecap dislocates, it typically moves towards the outer side of the knee joint. This lateral dislocation can cause severe pain and discomfort. The kneecap may visibly shift out of its normal position, and there may be difficulty in moving the knee.
Treatment Options
The initial treatment for a first-time kneecap dislocation involves rest and immobilization. A knee brace or knee immobilizer is applied to keep the knee in a straight position, allowing the ligament to heal properly. Resting the knee for about four to six weeks is usually sufficient for the ligament to heal in the majority of cases. However, in some individuals, the ligament may not heal properly or may not heal at all. This can lead to recurrent dislocation of the kneecap with minor disturbances in balance. In such cases, surgery may be required to reconstruct the ligament.
Medial Patellofemoral Ligament Reconstruction
Medial patellofemoral ligament (MPFL) reconstruction is a surgical procedure used to treat recurrent kneecap dislocation. During the procedure, a portion of the hamstring tendon is used to reconstruct the damaged ligament. The hamstring tendon is attached to the kneecap and the thigh bone, and specialized bio screws are used to fix it in place. This surgical technique has an excellent success rate, with more than 95% of people experiencing a full recovery. After the surgery, individuals can return to their usual activities, including sports, without significant discomfort.
Conclusion
In summary, kneecap dislocation is a common issue among young individuals. The kneecap, although a small bone, plays a crucial role in knee bending and straightening. When the kneecap dislocates due to injury, it can tear the ligament responsible for keeping it in place. While rest and immobilization may be sufficient for the ligament to heal in most cases, some individuals may require surgery for ligament reconstruction. Medial patellofemoral ligament reconstruction has a high success rate and allows individuals to return to their regular activities without discomfort. If you are experiencing symptoms of kneecap dislocation, consult with a healthcare professional to determine the best course of treatment for your specific condition.
