Morphometric study of upper end of tibia and its implications in total knee replacement

Abstract

: Knee deformities can be reliably assessed by using morphometric parameters of upper end of tibia. Total knee arthroplasties are done to treat many types of arthritis and injuries involving knee joint. So, there is a need to have data of various morphometric parameters of upper end of tibia in order to have better surgical outcomes. The present study was attempted to provide values of different parameters in the population of Bihar.: The present study was a cross-sectional and prospective study conducted on 50 tibia of unknown gender and age in the Department of Anatomy, Indira Gandhi Institute of Medical Sciences, Patna. Fully ossified, dried, macerated and thoroughly cleaned tibia were taken to measure different parameters of upper end with the help of digital vernier calliper. The data thus obtained were tabulated and analysed statistically using Microsoft excel software.: It was found that the diameters of medial condyle were more than the lateral condyle. The antero-posterior diameter was more than the transverse diameter in case of both the condyles. But the difference between the right and the left side was not statistically significant.: The present study will help in providing a baseline data for designing of the prosthesis used in total knee replacement surgeries. It will also be helpful to anthropologists and forensic experts.
