We substantiate a new technique for obtaining osteochondral autograft to replace osteochondral defects resulting from various lesions of the talar trochlea by means of morphological examination of the following microslides: talar cartilage (cadaver material), cartilage portion of the pre-achilles zone of the calcaneum, lateral femoral condyle, and necrotic area of the talus. Examination of the specimens of the pre-achilles cartilage of the calcaneus revealed a large number of poorly differentiated chondroblasts in the homogeneously stained extracellular matrix; the presence of all zones (superficial zone, zone of columnar structures, and “tidemark”). This is indicative of structural and functional preservation of this cartilage, which therefore can be considered as an autograft material. |
