The Use of Computer-Assisted Surgery During Patellofemoral Arthroplasty

  • Robin K. Strachan
  • Andrew A. Amis


During total knee arthroplasty (TKA), the patellofemoral joint (PFJ) has a tendency to be considered as an afterthought despite the fact that the patella and trochlea of the femur are frequently involved in certain patterns of knee osteoarthritis and deformity. Indeed, the PFJ in arthroplasty is a well-documented source of complications including subluxations, dislocations, tilts and impingements which are associated with pain and poor function [8, 30]. Such issues should therefore not be dismissed lightly (Fig. 15.1). Archibeck et al. [3] found that patellar tilt or subluxation occurred in 45 % of primary TKAs. Baldini et al. [4] reported high rates of pain and fracture when patellar issues were ignored.
