Introduction: A morphometric study of the upper end of the dry tibia bone explores the anatomical features and measurements of the tibial plateau, which is vital in knee replacement surgeries. By analyzing these dimensions, this research aims to uncover valuable insights with clinical significance. Understanding the morphometry of the tibial plateau facilitates implant design, surgical technique refinement, and patient-specific considerations, ultimately enhancing the accuracy and success of knee replacement procedures. Materials and Methods: In this cross-sectional and prospective study, 60 adult tibias (among which 30 belong to the right side and 30 belong to the left side) of unknown gender and age were studied in the Department of Anatomy, Nalanda Medical College & Hospital, Patna, Bihar. Using a digital vernier caliper, various upper-end characteristics were measured on a fully osseous, dried, macerated, and carefully cleaned tibia. Results: We observed that the mean anteroposterior diameter of the medial condyle was more than the lateral condyle, while the transverse diameter was more in the case of the lateral condyle on both sides. It was observed that the anteroposterior diameter of the intercondylar area was more on the left side. The transverse diameter of the intercondylar area of the upper end of the tibia at the anterior end as well as the middle narrow part was found more on the left side, while that of the posterior end was more on the right side. But the difference between the right and the left side was statistically insignificant. Conclusion: This study and its clinical significance in knee replacements seek to enhance our understanding of the tibial plateau's anatomical variations and their impact on surgical outcomes. By shedding light on these crucial aspects, we aspire to improve surgical precision, implant selection, and patient outcomes in knee replacement surgery.
