Study Finds, Anthropometric measurements of non-arthritic kn
A Study was conducted to investigate knees’ anthropometric characteristics. Secondary aims are as follows: (1) to study the anthropometric gender difference, (2) to compare results with other ethnic groups, and (3) to study the mismatch in comparison to geometric characteristics of modern TKA implant designs.

200 normal knee MRI scans were obtained for analysis. Linear measurements (anteroposterior (AP), mediolateral (ML), and aspect ratio (AR)) of the planned cut surface of the distal femur (f) and the proximal tibia (t) were evaluated.

--A significant difference between both sexes was found, males had larger measurements in anteroposterior and mediolateral, the mean femoral and tibial AP and ML measurements were different.

--None of the 7 studied TKA systems matched the largest ML or the smallest AP dimensions of the distal femur in the study.

Conclusively, A significant difference was found between males’ and females’ knee anthropometric characteristics.
