Stiff Knee (Arthrofibrosis)

Knee arthrofibrosis can be caused by various factors, such as trauma, surgery (especially ACL or knee replacement surgery), prolonged immobilization of the knee joint, infection, or inflammation. These factors can lead to excessive scar tissue formation, which restricts normal knee joint movement.

The occurrence rate of knee arthrofibrosis varies, but it is relatively uncommon. However, it is more commonly seen in certain populations, such as individuals who have undergone knee surgeries or experienced severe knee injuries.

• Pain
• Stiffness
• Swelling
• Limited range of motion
• A feeling of tightness or pulling in the knee joint.
• Difficulty straightening or bending the knee.
• Instability while walking or performing physical activities.

The combination of a detailed history, including your past surgical history, and comprehensive physical examination is the key to a successful diagnosis of knee arthrofibrosis. Dr. Chahla and his team will perform a comprehensive physical exam to assess the range of motion in your knee joint, look for signs of inflammation or swelling, and feel for areas of tenderness or crepitus (grating or grinding sensations). Your gait (the way you walk) will also be evaluated to identify any abnormalities.

In addition to the physical examination, Dr. Chahla may order diagnostic imaging, such as x-rays or an MRI of the knee, to further evaluate post-surgical changes and hardware placement from your previous surgery if applicable.
