Development and validation of multiple linear regression models for predicting total hip arthroplasty acetabular prosthesis.

Purpose: To establish a multivariate linear equation to predict the diameter (outer diameter) of the acetabular prosthesis used in total hip arthroplasty.

Methods: A cohort of 258 individuals who underwent THA at our medical facility were included in this study. The independent variables encompassed the patients' height, weight, foot length, gender, age, and surgical access.
