Open the catalog to page 3United Orthopedic The PS (posterior stabilized) and CR (curciate retaining) femoral components have the same design features, including 2 mm A/P and M/L increments, extended patella groove, and consistent intercondylar width. The extended patella groove is designed with increased contact area between the patella and femoral implants to allow for optimal patella tracking. Smaller intercondylar bone removal together with rounded corners help avoid the risk of intercondylar fracture for PS box preparation. Two CR femoral component types are available - R (Cemented type) C - R Porous (Sintered...
