United Orthopedic U2 Knee – The U2 Knee system is a comprehensive and organized total knee system designed to restore knee function throughout a full range of motion. The U2 Knee system provides full interchangeability and multiple fixed-bearing insert options. In addition to the commonly used CR and PS type inserts, U2 Knee system offers ultracongruent insert options, in order to offer more extensive choices for broader patient morphological demands. The tibial baseplate is available for varying levels of bony defects and fixation preferences in the following options – cemented type,...

United 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...
