Arthrosurface® offers two systems for the knee that are approved in the United States. The UniCAP® system is designed for the medial/lateral compartments and consists of 10 different femoral surface options and 6 inlay tibias. The tibia is prepared arthroscopically using a unique retrograde cutter and is the only Uni implant is the world that allows preservation of the meniscus.
The Patello Femoral HemiCAP® is available in 2 different sizes, with 21 trochlear convexities and 13 different patellas making it the most versatile PF system in the world. Both the trochlea and patella are designed as inlay implants in order to maintain and restore congruency in the PF joint which is very important for proper patella tracking.
The fit achieved using the precision instrumentation of either the UniCAP® or HemiCAP® system is a significant improvement over existing joint replacement products. Arthrosurface® fits the implant to the patient at the time of surgery using an intraoperative 3-dimensional mapping system. This tailored joint resurfacing is a key principle with all Arthrosurface® implants as they are designed to match the patients’ cartilage curvatures instead of the boney anatomy referenced in other systems. Tailored joint resurfacing restores the native joint biomechanics and preserves bone and tissue. By leaving all the supporting tissues intact, proprioception is maintained. Our goal with the UniCAP® or HemiCAP® system is to restore normal joint function by preserving native anatomy and resurfacing only the damaged surfaces in the knee. Just as each surgeon tailors the treatment to the patient, you can now tailor the implants to fit the patient as well.
In select geographies, the original HemiCAP® Classic for Focal Condyle lesions is also available.
**The Femoral Condyle system is available in most international markets via CE mark and in the US it is currently being evaluated as part of a IDE clinical study at a number of sites in the US.**
