Patellar Groove Replacement (PGR) is indicated for severe articular cartilage damage, congenital dysplasia, deformities, femoropatellar arthritis, patellar luxation, severe comminuted patellar fractures, or degenerative patellofemoral disease secondary to cruciate ligament deficiency. The implant position can be adjusted to match the anatomy of the femur and tibia.
System Components
Femoral component
Ti6Al4V titanium alloy; articular surface designed from anatomical data for an optimal fit; multi-point machined and mirror polished.
