Morphological changes of the sequestered fragment in osteochondritis dissecans of the knee condyles
Abstract
The results of macroscopic and histological postoperative examination of the sequestered osteochondral bodies of 9 patients, in some cases having a «bridge-type» support by scar tissue and some mild signs of viability of these fragments, were presented in order to ground the appropriateness of their refixation in the bed. Studies showed that the presented removed osteochondral bodies are not viable, since in all histological specimens, the major pathologic features characteristic for nec-rotizing processes with degenerative changes of the cartilage cover are present. In 3 cases (33.3 %), the pathological changes similar to the histological structure with osteomyelitis processes are found. Judging on the results of morphological studies it can be stated that the refixation of the sequestered fragment has no pathologic grounding of the viability of the sequestrated body and has no sense because of possible complications and a very low probability of revascularization of the fragment after fixing it to the sclerotic bed.
