Osteoarthritis of the knee is a common problem among the elderly worldwide. Total knee arthroplasty (TKA) is the most important treatment option with good clinical and long lasting results even in young and active patients. Nowadays, there is still debate whether or not to resurface the patella. Patellofemoral arthoplasty (PFA) is one of these surgical options and is also a unicompartmental knee arthroplasty of the anterior compartment with a limited number of published clinical results. A successful implantation of a PFA depends upon many factors. PFA is a good treatment option for patients with isolated PFOA and good or excellent clinical results can be obtained in 85-90%. This review will focus on prosthesis implantation, implant design and the efficacy of the prosthesis.
