【 摘 要 】

The variability in the decision about whether to resurface the patella in total knee replacement (TKR) is influenced by different factors including geographic location, training of surgeons, implant design and level of constraint. There are currently three possible approaches to the patella during primary total knee arthroplasty: always resurface, never resurface, and selectively resurface. This last option is mainly dictated by pre and intraoperative findings such as preoperative diagnosis, quality of the articular cartilage, patellofemoral congruence and tracking at the time of surgery. Disagreement is also present in the literature because there are different randomized controlled trials leading to different evidence and conclusions, that will be discussed in this review. In the last decade the improvement in patellar and femoral component design and some advances in the surgical technique may have made patellar resurfacing more attractive. The traditional component is a cemented and all-polyethylene patella, with a dome-shaped design to favour component insertion (Fig. 1).1 The onlay design reduces the risk of patellar fracture and the amount of sacrificed bone.
