Hemicap Patello-Femoral Resurfacing System
Arthrosurface
FDA Clearance Information
The HemiCAP Patello-Femoral Resurfacing System was cleared through the FDA 510(k) pathway on November 9, 2007. Manufactured by Arthrosurface, it is classified as a Class 2 device under product code KRR.
What It Is
FDA-Cleared Indications
- Treatment of cartilage damage involving the patellofemoral compartment of the knee.
- Use in patients with localized cartilage lesions or degenerative changes affecting the patellofemoral joint.
Clinical Applications
- Focal resurfacing of a damaged area on the patella or femoral trochlea.
- Treatment of symptomatic patellofemoral cartilage defects when conservative treatment has not provided adequate relief.
- Use during partial knee joint resurfacing rather than total knee replacement in appropriately selected patients.
- Treatment of localized patellofemoral degeneration in patients with preserved, otherwise suitable knee compartments.
Practical Considerations
- The implant is available in multiple sizes and is selected to match the patient's anatomy and the size and location of the cartilage defect.
- Implantation is performed by an orthopedic surgeon using open or minimally invasive knee-surgery techniques, with imaging and instruments selected according to the surgical system.
- Patient selection is important; advanced arthritis involving multiple knee compartments, infection, inadequate bone stock, or other contraindications may make this type of resurfacing unsuitable.
- MRI safety and artifact information depend on the exact implant materials and labeling; the operative implant record and current manufacturer MRI instructions should be reviewed before scanning.
- The expected durability depends on patient age, activity, alignment, bone and cartilage condition, and progression of arthritis. The device does not prevent degeneration elsewhere in the knee.
