STRUCTURE OF THE KNEE ARTICULAR CARTILAGE AFTER THE FEMUR AND TIBIA EXTRA-ARTICULAR INJURY.

Objective: The aim: To study the microscopic, ultramicroscopic, and histomorphometric features of the knee articular cartilage in rats with an extra-articular injury of the femur and tibia.

Patients And Methods: Materials and methods: 60 white laboratory rats divided into three groups (I - control; II - animals with traumatic femur injury; III - animals with traumatic tibia injury) were used for the study. The light microscopy was performed by Olympus BH-2 microscope (Japan), transmission electron microscopy - by JEM-1230 microscope (Japan).
