How to Treat Dislocated Kneecap?

What is a Dislocated Kneecap?

A dislocated kneecap, or patellar dislocation happens when the triangular bone in the front of the knee, called the patella, is forcefully pushed out of its usual place within the groove of the thigh bone (femur). This displacement can cause pain, swelling, and instability in the knee joint. Typically, the kneecap moves smoothly within a groove between the thighbone and shinbone when you bend and straighten your leg. However, during a dislocation, the kneecap is forced out of this groove, often tearing ligaments and causing discomfort. Most dislocations occur laterally, moving to the side of the groove, and are often caused by sudden impacts or twisting motions. While painful and debilitating, some dislocations may spontaneously correct themselves.

Why Does a Dislocated Kneecap Occur?

Dislocated kneecaps often occur due to sudden twisting or direct impact on the knee joint during activities such as sports or falls. Factors that can increase the risk of patellar dislocation include weak thigh muscles, abnormal alignment of the knee joint, hypermobility, and previous knee injuries.

How to Identify a Dislocated Kneecap?

Symptoms of a dislocated kneecap may include:

  1. Sudden onset of severe pain in the knee
  2. Swelling and bruising around the knee joint
  3. Inability to straighten or bend the knee
  4. Feeling of the knee giving way or buckling
  5. Visible deformity or abnormal positioning of the patella

If you suspect a dislocated kneecap, seek medical attention immediately for evaluation and treatment.


Treatment Solutions for a Dislocated Kneecap

  1. Reduction: The primary treatment for a dislocated kneecap involves reducing, or realigning, the patella back into its normal position within the knee joint. This can often be accomplished by a healthcare professional using gentle manipulation techniques.
  2. Immobilization: Following reduction, the knee may be immobilized with a brace, splint, or cast to stabilize the joint and prevent further displacement of the patella. Immobilization allows the injured structures to heal properly and reduces the risk of recurrence.
  3. Physical Therapy: Physical therapy plays a crucial role in the rehabilitation of a dislocated kneecap. Therapeutic exercises are designed to strengthen the muscles around the knee, particularly the quadriceps and hamstrings, to improve stability and support the joint. Range of motion exercises and flexibility training may also be incorporated to restore normal knee function.
  4. Bracing: In some cases, wearing a knee brace or patellar stabilizing brace may be recommended to provide additional support and prevent recurrent dislocations. These braces help keep the patella properly aligned within the knee joint during movement and activities.
  5. Surgery: In severe cases of recurrent or complex dislocated kneecaps, surgical intervention may be necessary to repair damaged ligaments, tendons, or other structures around the knee. Surgical procedures such as patellar realignment or ligament reconstruction may be performed to stabilize the joint and reduce the risk of further dislocations.

Benefits of Treating a Dislocated Kneecap

  1. Pain Relief: Treatment for a dislocated kneecap can alleviate pain and discomfort associated with the injury, allowing individuals to resume normal activities with less discomfort.
  2. Restoration of Function: Physical therapy and rehabilitation help restore strength, flexibility, and range of motion in the knee joint, allowing for improved functional abilities and mobility.
  3. Prevention of Recurrence: Strengthening exercises and bracing techniques can help prevent recurrent dislocations of the kneecap, reducing the risk of future injuries and instability.
  4. Improved Stability: By strengthening the surrounding muscles and supporting structures of the knee, treatment can improve joint stability and reduce the likelihood of instability or buckling during physical activities.
  5. Optimal Recovery: Proper management and rehabilitation of a dislocated kneecap promote optimal healing and recovery, minimizing the risk of long-term complications and allowing individuals to return to their normal activities and sports safely.
