EVALUATION OF ANATOMICAL VARIATION OF POSTERIOR TIBIAL SLOPE IN PATIENTS VISITING TERTIARY CARE HOSPITAL – AN OBSERVATIONAL STUDY

Abstract

The posterior tibial slope (PTS) is a crucial anatomical parameter which significantly affects knee biomechanics and orthopaedic evaluation.This analysis's goal was to assess how radiographic PTS varied among persons with knee pain and how it related to anthropometric, demographic, and osteoarthritis variables. One hundred people who frequent tertiary care hospitals are the subjects of this prospective, observational research. PTS was measured using lateral knee radiographs. The relationships with age, sex, body mass index (BMI), and Kellgren–Lawrence (KL) grade were evaluated using group comparisons, correlation analysis, and multivariable linear regression. The extreme measurement was omitted from the sensitivity analysis. Mean PTS was 13.92 ± 2.48°. Women had higher mean PTS than men (14.46 ± 2.56° versus 13.13 ± 2.16°; p = 0.006). PTS correlated positively with age (r = 0.268; p = 0.007) and negatively with BMI (r = −0.343; p < 0.001). There was no considerable association between KL grade and PTS (p = 0.526). In sensitivity analysis, age (B = 0.065; p = 0.001) and BMI (B = −0.280; p < 0.001) continued to be significant. In this symptomatic hospital population, age and BMI were independently related to radiographic PTS. Results are significant and should be replicated in a larger, more varied population.
