Could a simple X-Ray measurement outperform BMI in knee surgery safety?

This study investigates whether the thickness of fat over the shin bone, measured on a standard knee X-ray, is a better predictor of infection after total knee replacement than Body Mass Index (BMI). Researchers will review data from 400 adults who had knee replacement surgery, comparing infection rates within 12 months against both BMI and this fat measurement. The goal is to see if this simple measurement could help doctors make fairer, more personalized decisions about who is suitable for surgery.
