PFR is the abbreviation for patellofemoral replacement. Only a piece of the knee is resurfaced in this kind of partial knee replacement. For individuals whose damaged bone as well as cartilage is restricted to the bottom of the kneecap & the groove in the femur, where the patella rests, this surgery provides an option against complete knee replacement. Patellofemoral arthritis is the medical term for the condition that requires this surgery. There is less harm to knee soft tissues since patellofemoral replacement is performed through a smaller incision. This frequently enables patients with patellofemoral replacements to heal and resume regular activities more faster than individuals with total knee replacements.
Patellofemoral arthritis is given a diagnosis when the joint layer of the patella as well as the trochlea, the notch on the femur where the patella slides when the knee bends or straightens, have lost a lot of cartilage. Patellofemoral arthritis is caused by things like patellar instability, a serious injury to the patella like a fracture, mal-alignment, which puts more stress on the patella and causes the cartilage to wear out early, and osteoarthritis that doesn’t have a clear cause.
