Natural Knee II System Patello-femoral Joint
The Same Proven Design Elements as the Natural-Knee II Primary System
|
Patello-femoral joint arthroplasty (PFA) has been shown to be an alternative treatment for osteoarthritis that is isolated to the anterior compartment of the knee joint. 1 By limiting the reconstruction to the patello-femoral joint, and retaining the soft tissues that contribute to normal knee motion, the procedure can result in the preservation of healthy bone stock and knee kinematics. It provides a conservative option for younger patients who may otherwise be considered for total knee arthroplasty (TKA). The PFA procedure can be converted to a TKA procedure intraoperatively if the exposure reveals unexpected involvement of the tibiofemoral joint. Also, if necessary, a PFA can be revised to a TKA. Since 1986 the Natural-Knee System has been used to successfully treat more than 450,000 patients. The Natural-Knee II Patello-femoral Joint System incorporates the same proven design elements as the Natural-Knee II Primary System and applies them to isolated patello-femoral joint disease. |
