Isolated patellofemoral arthritis is not uncommon and a well-recognized variant of the osteoarthritic knee with no clear consensus in treatment. The prevalence of isolated patellofemoral arthritis is as many as; 11% of men and 24% of women, older than 55 years old. Nonoperative and many forms of operative treatments have failed to demonstrate long-term effective results in the setting of advanced patellofemoral OA. Previous publications have demonstrated as many as 19% of patients experience residual anterior knee pain when TKA is performed for isolated patellofemoral OA. Robotic-assisted patellofemoral arthroplasty when used on the properly selected patient has good outcomes and preserves the natural tibiofemoral biomechanics and kinematics.

The current indications for patellofemoral arthroplasty are degenerative or posttraumatic arthritis isolated to the patellofemoral joint with severe symptoms, of the patellofemoral joint degeneration, affecting activities of daily having failed prior conservative procedures.

Inlay-style patellofemoral trochlear prostheses were often placed in excessive internal rotation leading to patellar maltracking; with robotic-assisted patellofemoral arthroplasty, these issues can been eliminated by controlling trochlear rotation. Presently with the advances in prosthesis design and improved surgical technique which have optimized patellar tracking, survivability of patellofemoral arthroplasty is enhanced with progression of tibiofemoral arthritis as the most common cause of failure.
