BACKGROUND
Osteoarthritis of knee joint is one of the major health problems, due to the
evolution of erect posture. Upper weight bearing end of tibia is most vulnerable to
damage in such patients. Total knee arthroplasty and unicompartmental
arthroplasty are the most frequently done procedures, which require the use of
adequate knee prosthesis. So, the present study was focused at providing
morphometric data of upper articular end of tibia for designing the tibial
component of prosthesis.
METHODS
The present study has been conducted in SAMC & PGI, Indore in the Department
of Anatomy. 80 dry tibia bones were studied, of which 33 were right sided and 47
were left sided. Maximum anteroposterior (AP) length and width of upper surface
of medial and lateral condyles and intercondylar area were measured with digital
vernier caliper.
RESULTS
The average anteroposterior diameter was found to be greater than the transverse
diameter for both the condyles and the intercondylar area, irrespective of side.
Furthermore, the anteroposterior diameter and the transverse diameter of medial
condyle was more than that of lateral condyle on both the sides. In intercondylar
area, the anteroposterior diameter was found to be more on right side while
transverse diameter was more on left side.
CONCLUSIONS
The present study demonstrates the accurate complete comparative
measurements of all the parameters of upper surface of medial and lateral
condyles and intercondylar area. The morphometric data obtained will provide
guidelines for designing tibial component of knee prosthesis in central Indian
population. Apart from clinical significance, the study has anthropological and
medicolegal importance as well.
