The HemiCAP Patello-Femoral Resurfacing Prosthesis was cleared via the 510k pathway on March 16, 2006. Manufactured by Arthrosurface, it is a Class 2 medical device.

What It Is

The HemiCAP Patello-Femoral Resurfacing Prosthesis is a surgical implant designed to resurface the patellofemoral joint, which is part of the knee. It is used to treat osteoarthritis by providing a smooth, contoured surface that mimics the natural anatomy of the joint. This device helps reduce pain and improve mobility by replacing damaged cartilage with a metal cap that fits precisely onto the femur and patella.

Clinical Applications

This device is commonly used in orthopedic surgery, particularly in patients with isolated patellofemoral osteoarthritis. It is suitable for patients who have not responded to conservative treatments and are not candidates for total knee replacement. The procedure is often performed in hospital surgical settings, and the typical patient population includes middle-aged to older adults, especially women, who experience significant knee pain and functional impairment.

Indications for Use

The FDA indications for this device include treatment of patellofemoral joint osteoarthritis. It is intended for patients with localized cartilage damage in the knee, particularly those who experience pain and limited mobility due to the degeneration of the joint surface.

Practical Considerations

The HemiCAP system offers various sizing options to accommodate different anatomical variations. It is important for surgeons to ensure proper alignment and fit during implantation to maximize the functional outcome. Compatibility with existing surgical instruments and techniques is generally straightforward, but precise surgical technique is crucial for optimal results.

Related Literature

The linked study from 2019 evaluated the clinical and functional outcomes of patellofemoral resurfacing arthroplasties. It highlighted the effectiveness of anatomical and biomechanically appropriate systems in treating patellofemoral osteoarthritis, particularly in women. The study found improved functional results and earlier intervention stages. However, limitations included a focus on a specific patient demographic and the need for longer-term follow-up data.
