Abstract
Background: Customization of Total Knee Replacement (TKR) and the design of knee prostheses are paramount. Conventionally, surgeons select from a spectrum of pre-fabricated implants, assessing their fit based on the patient’s knee morphology via magnetic resonance imaging. Aim and Objective: This research endeavours to identify and quantify gender-related variations in knee morphometry by examining the distal femur and proximal tibia of the population of North India. Materials and Methods: A Descriptive cross-sectional study included 59 males and 59 females’ knees. A 1.5 TESLA MRI unit (Avanto Magnetomtim + dot system, Siemens, Erlangen, Germany) was utilized for imaging. The morphological features of proximal Tibia and distal femur were taken. Correlation between morphometric parameters were calculated using Karl Pearson’s correlation coefficient. P-value <0.05 was set statistically significant. Results: All the FEMUR parameters were significantly higher in males than females. The mean FML in males was 8.04±0.50SD and in females was 6.97±0.33SD (P<0.05). Mean FMAP in males was 5.98±0.46SD and in females it was 5.36±0.35SD (P<0.05). All the TIBIA parameters were significantly higher in males than females. The mean TML in males was 7.56±0.37SD and in females was 6.49±0.28SD (P<0.05). Mean TAP in males was 4.64±0.41SD and in females it was 4.13±0.25 (P<0.05). Conclusion: Variations in bone dimensions were attributed to a complex interplay of genetic, ethnic, and environmental factors. In conclusion, this study makes a substantial contribution to the understanding of knee joint morphology.
