Isolated arthritis in the patellofemoral joint (knee cap) is less common that medial compartment arthritis but can cause significant anterior knee pain and debilitating symptoms which limit quality of life.
Diagnosis is made on history, clinical examination findings, plain x-rays or MRI scans.
In young active patients where joint preservation is paramount, a patellofemoral joint replacement may be considered. This is essentially a resurfacing procedure where diseased tissue is removed and a polyethylene (plastic) implant is placed on the under surface of the patella along with a small metallic component to resurface the worn femoral trochlea.
Initial recovery is faster that a full knee replacement as the procedure is much less invasive and excellent results can be achieved in terms of knee function and patient satisfaction.
