The relationship between subchondral bone strength, cartilage thicknees and contact pressure of the tibio-femoral joint

Abstract

Six fresh knee specimens of human cadevera were tested. Contact pressure of the femoro-tibial joint was measured by transistor pressure gauges which were connected to pipes (1.5mm diameter) inserted in the cartilage of the tibia plateau. To measure the subchondral bone strength, a pointed-needle for penetration test, having a base diameter 2.5mm with 90 degree conical profile was advanced at the conant speed (1.0mmısec.) at a right angle to an articular surface. Thereafter, cartilage thickness was measured by trepanning cartilage. Contact pressure was high at the areas uncovered by the menisci. The subchondral bone strengt showed high values at the area uncovered by the meniscus on the medial tibia plateau and at the areas uncovered and covered by the meniscus, which extended posteriorly from the uncovered area on the lateral tibia plateau. The distribution of the subchondral bone strength of the femur condyle was roughly congruous with that of the tibia plateau. The distribution of the cartilage thickness was similar to that of the subchondral bone strength. From these results, the areas of high values of subchondral bone strength and cartilage thickness were coincident with those on which high stress was applied.
