Results of total knee replacement for isolated patellofemoral arthritis: when not to perform a patellofemoral arthroplasty.
Many procedures have been used to treat advanced isolated patellofemoral arthritis, with varying results. Patellofemoral arthroplasty (PFA) is a bone-conserving procedure that has shown short-term success but has relatively high revision rates. Total knee arthroplasty (TKA) has been recommended for treatment of this disease in patients who are older than 60 years of age. Recent literature indicates that PFA is most successful in patients who have isolated patellofemoral arthritis secondary to trochlear dysplasia or patellar fracture and in patients who are younger than 60 years; TKA is recommended for older patients who have primary or idiopathic isolated patellofemoral arthritis.
