Patello-Femoral - Product Overview

The Arthrosurface HemiCAP system is a surgical method for the treatment of localized cartilage lesions and defects in the major joints. This system is comprised of three elements; a three-dimensional mapping technology, a set of instruments to map and prepare the damaged area and a cobalt-chrome and titanium implant placed opposite to a polyethylene implant. The system precisely aligns the surface of the implant to the contours of the patient's articular cartilage surface, thus filling the defect and restoring a smooth and continuous articular surface. The HemiCAP system has been developed so that it can be utilized via minimal access surgical techniques.

There are 2 systems that comprise the Patello-Femoral Line.  The first is the Classic Focal HemiCAP which is used for isolated and well contained lesions of the trochlea groove and the patella.  The second system is called the WAVE and is used for those patients that have more diffuse or extensive damage to their PF joint.  Both systems use the same proven intraoperative mapping technology of all HemiCAP systems.

HemiCAP PF Focal and the HemiCAP WAVE implants

The HemiCAP Instrument Set enables the surgeon to accurately place the implant and precisely map the curves of the articular surface, in real-time, under direct or arthroscopic visualization, with no angle-induced errors or magnification errors that might exist with MRI, or X-ray imaging techniques.
The HemiCAP system is intended to provide an effective interim means for managing pain and disability in the middle-aged patient until a total joint replacement treatment option becomes more necessary, and is part of a clinical treatment strategy to help avoid early-age-revision scenarios. The prosthetic may also provide a treatment option for the older patient who may not tolerate the morbidity of a total joint replacement procedure.
The HemiCAP implants and instruments are designed to remove a minimal amount of bone stock, preserve functional structures and tissues, and allow for an uncomplicated removal in the event of revision.
