Patellofemoral Replacement
Patellofemoral replacement is a specialized knee surgery that targets damage limited to the front compartment of the knee, specifically between the kneecap and the femur. Instead of replacing the entire joint, only the affected surfaces are resurfaced with prosthetic components. This focused approach helps relieve pain, restore joint alignment, and preserve healthy bone and ligaments, making it an effective option for selected patients with isolated patellofemoral arthritis.
About Procedure
Patellofemoral replacement is an advanced, bone-preserving orthopedic procedure designed for patients suffering from anterior knee pain due to cartilage degeneration behind the kneecap. Unlike total knee replacement, this surgery replaces only the patellofemoral compartment, allowing for more natural knee mechanics and faster recovery. The procedure involves reshaping the underside of the patella and the corresponding groove of the femur, followed by placement of smooth prosthetic surfaces that enable friction-free movement. It is commonly recommended for younger or active patients whose arthritis is confined to this compartment. With improved implant design and surgical precision, modern patellofemoral replacement offers durable pain relief, improved mobility, and high patient satisfaction when carefully selected based on clinical evaluation and imaging findings.
When to Consider
Patellofemoral replacement is considered when knee pain is specifically localized to the front of the knee and is caused by isolated patellofemoral arthritis that does not respond to medications, physiotherapy, or injections. It is especially suitable for patients who experience pain while climbing stairs, squatting, or sitting for long periods. Candidates typically have preserved cartilage in other parts of the knee, stable ligaments, and proper alignment. It is also recommended for younger or moderately active individuals who want to maintain more natural knee movement while delaying or avoiding a full knee replacement. Careful imaging and clinical assessment are essential to confirm that arthritis is limited to the patellofemoral compartment before proceeding.
