Previous studies suggested that increased postoperative patellar strain after resurfacing in Total Knee Replacement (TKR) is a possible cause of complications development, such as patellar fracture or anterior knee pain (AKP). However, patellar resurfacing is usually overlooked in TKR planning and surgeons do not have special tools to estimate possible strain levels in postoperative patella, and, thus, risk of complications. On the other hand, the knowledge on the patellar strain levels experienced by TKR patients during daily activities is also sparse. The aim of this study was to evaluate patellar strain in retrospective TKR patients using validated patient-specific numerical models of squat. Correlation between predicted strain and patient data, such as body weight, volume of resurfaced bone and its density that can be easily obtained during preoperative planning, was further analyzed.
