Abstract: Total Knee Arthroplasty (TKA) is being used with the main goal of pain reduction and lower extremity alignment correction with a proven positive impact. Surgeons’ criterion for the suitability of extremity alignment is to compare them (The angle between femur mechanical axis with tibial mechanical axis) with extremity mechanical axis (a line connecting the midpoint of the femoral head to the midpoint of the talus). Most professionals consider ideal up to 3 degrees difference between extremity alignment with extremity mechanical axis after surgery, thereby increasing the life of the arthroplasty components. In this study, the intention was to show parameters associated with surgery success with the evaluation of patients with ATK successful surgery. In this study, 102 patients with TKA operation in Fajr Hospital of Tehran were selected and required information was extracted from their archived files. Having no arthroplasty after the operation was the main criterion for selecting these patients. Statistical analysis showed that parameters such as BMI, gender, urinary tract infection, and so do not affect the success of ATK surgery. However, it was shown that there is a significant relationship between the success rates of surgery on left knee with the type of surgery. Although there is no significant relationship between some underlying factors such as blood group, gender, or urinary tract infections with the success of TKA surgery, the type of surgery can be an important and determinant factor in the success of the surgery. Statistical analysis on TKA surgery can provide useful information to successfully conduct this type of operation in the future.
