Patellar component positioning in total knee arthroplasty: a cadaver study and review of the literature.

This article explores the positioning of the patellar component in total knee arthroplasty (TKA) and its impact on patellar tracking. It reviews existing literature and presents the findings of a cadaver study on the effects of different implant locations. The study suggests that medially placed, optimally sized patellar components result in the best tracking within the femoral groove. However, there is no consensus on the appropriate degree of medialization, and individualized positioning may be necessary based on the patient's anatomy. The article emphasizes the need for further research to validate the optimal placement of the patellar implant. [Extracted from the article]
