Patient-Specific Patellofemoral Arthroplasty

In this chapter we review the topic of patellofemoral arthroplasty from a historical, technical, and clinical perspective. Emphasis is placed on the design rationale, surgical technique, and clinical results of so-called “patient-matched“ or “patient-specific“ patellofemoral arthroplasty in which the trochlear implant is matched to the anatomy of the individual patient through the use of pre-operative computerized imaging scans (Fig 1).
