Comparative study of posterior tibial slope & metaphysio-diaphyseal angle in osteoarthritis knee and normal knee attending tertiary care centre in North-east India
Objective: The purpose of this study is to establish normal values and explore potential correlations of the posterior tibial slope(PTS) and metaphysio-diaphyseal angle(MDA) within the study population.

| Summary: | Objective: The purpose of this study is to establish normal values and explore potential correlations of the posterior tibial slope(PTS) and metaphysio-diaphyseal angle(MDA) within the study population. These measurements are critical for assessing knee joint biomechanics, which influence various orthopaedic surgical outcomes and rehabilitation processes. Methods and materials: We conducted a cross-sectional study involving 347 adults from various regions across North-east India. Participants were selected based on inclusion criteria that excluded previous knee surgeries or Fractures around knee involving proximal tibia. The PTS and metaphysio-diaphyseal angle were measured using x-ray knee lateral view. Each image was analysed using advanced software to ensure precise angle determination. The data are tabulated in Microsoft excel and analysed with SPSS V.24 software. Results: our study shows that mean posterior tibial slope and mean MDA in normal group are 9.78°(±2.40) and 19.58°(±4.27) respectively. Mean PTS and MDA in osteoarthritic group are 14°(±2.26) and 24.59°(±3.95) respectively. There is linear relationship between MDA and PTS with correlation coefficient (r) is 0.620. Sensitivity and specificity of MDA for detecting OA are 81.1 % and 75.4 %, respectively. Sensitivity and specificity of PTS for detecting OA are 91.2 % and 68.5 %, respectively. Conclusion: MDA and PTS are comparatively higher in value in osteoarthritic group when compared to normal group. It also serves as a good marker to detect OA and there is a linear correlation between PTS and MDA. |
