Knee cap replacement, also known as patellofemoral arthroplasty, is a surgical procedure designed to treat severe knee cap damage or arthritis. This procedure involves replacing the damaged cartilage and bone of the kneecap with an artificial implant. While less common than total knee replacement, knee cap replacement can provide significant pain relief and improved function for patients with eligible conditions.
Causes of Knee Cap Damage
Several factors can contribute to knee cap damage, including:
Injury: Direct trauma, such as a fall or sports injury, can lead to fractures or dislocations of the kneecap.
Osteoarthritis: Degenerative arthritis can affect the cartilage beneath the kneecap, causing pain and stiffness.
Patellofemoral pain syndrome: This condition, often referred to as "runner's knee," occurs when the kneecap misaligns or rubs against the femur.
