Summary:To evaluate the accuracy and analysis of the influencing factors of the tibia prosthetic coronal alignment after total knee arthroplasty without tibia extramedullary cutting guide. In the study, 76 patients (96 knees) who had primary total knee arthroplasty in Peking University First Hospital from February 2012 to April 2016 were selected retrospectively. All of the cases were performed by the same experienced orthopedic surgeon team. The patients were divided into 2 groups randomly: tibia cutting without guide group and tibia cutting with extramedullary guide group. Lower extremity standard anterior and posterior X-ray films of the knees were taken before and after surgery, and the anatomical tibial angle (AT), the posterior slope angle (PSA) before and after surgery, the tibia component angle (TCA) were measured in the X-ray films. We also recorded the beginning and finishing time of the operation, the operation sequence of the day respectively at the same time. The data were analyzed by correlation analysi
