Introduction: Nowadays, one of the most common practices in orthopedic surgery is the Total Knee Arthroplasty. Logistic equipment, including prostheses, is the cornerstone of this surgical procedure. Clearly having a general overview of the size of consumable prostheses, the surgeons will act more confidently.

Materials and Method: This descriptive-analytic study employed a census method based on the inclusion criteria of the medical records of all patients who underwent knee replacement surgery in Besat Hospital of Hamedan in 1395 (2016-17) in terms of body mass index, age, gender, and size of tibial and femoral components. Data were analyzed by SPSS software version 16.

Results: A total of 214 patients were included: 21.5% male and 78.5% female. The mean age of patients was 67.95 years, and the mean body mass index was 27.98 kg/m2. As for the assessment of the size of components, most tibial components were of medium size (49.5%) and femoral components were of small size (65.9%). It was seen that there was an inverse correlation between tibial component and body mass index (BMI), and a direct and significant correlation between tibial component and height and weight in terms age and gender (p<0.05). Nevertheless, the correlation between femoral component and weight was statistically significant only at ages under 65 years and it was indirect (p=0.02).

Conclusion: Determining factors of the size of components used in joint replacement surgery include body mass index (BMI), weight and height of the patients for tibial surgeries, and weight of the patients for femoral ones.

Keywords: Body mass index (BMI); tibial component; femoral component
