Plastic patella resurfacing has functioned well in most CR and PS designs but there
are still some residual problems of suprapatellar soft tissue catching in the
intercondylar femoral groove, particularly with PS designs. Overall, short-term
problems with both designs are usually associated with inadequate technique the
long-term, accumulation of wear particles can cause osteolysis and component
loosening. Pearls: Don’t Over Stuff PF Joint. Soft tissue balance in flexion and
extension. Maintenance of Joint Line Deep Trochlear Groove (R & L) Appropriate
sizing and avoid anterior placement of femoral component. Lateralization of femoral
and tibial componentMeta-analysis of patella resurfacing 14 Trials: Anterior Knee
Pain was significantly higher in non-resurfaced group. Overall Patient Satisfaction
was significantly less. Secondary resurfacing for anterior knee pain in 8.7%.
Conclusion: All patellae should be replaced!
