Morphometric Analysis of Upper End of Tibia

Abstract

Introduction: The present study aims to assess different morphometric parameters of condylar and intercondylar surface of tibia and to compile the results, analyze and formulate a baseline data for future studies with relevance to Indian population and also to compare the current data with accessible literature for pertinent surgical utilities. Morphometric parameters of upper end of tibia can be used to guide treatment and monitor outcome of total knee replacement surgeries. Information regarding morphometry of upper end of the tibia is vital as it provides reliable method of assessing knee deformity. Materials and Methods: The study group comprised of 50 male and 50 female adult human tibiae. Morphometric measurements of medial condyle, lateral condyle and intercondylar area of tibiae were meticulously recorded with digital Vernier calipers with a least count of 0.01 mm. Student’s t-test was used with significant level of p-value < 0.05 and 95% confidence interval. Results: All measurements were found to be statistically significant when compared between the two sexes on both sides (p-value<0.05). Anteroposterior measurements were found to be greater than transverse measurements for both medial and lateral condyles. Furthermore, both anteroposterior and transverse measurements were greater in medial condyle than in lateral condyle on both sides and sexes. Conclusion: The present study is an endeavor to provide a base line data pertaining to morphometric details of upper end of tibia with reference to unicompartmental and total knee arthroplasty in Indian population. The results of the study assume special importance in view of the technical advancements in reconstructive surgical procedures in orthopedic practice.
