Biochemical and metabolic characteristics of articular cartilage from osteonecrotic human femoral heads
HJ Mankin, AZ Thrasher and D Hall
The cartilage from nine osteonecrotic femoral heads (six post-traumatic and
three corticoid-induced) was obtained at the time of total hip replacement
and studied by biochemical and metabolic techniques. The data obtained were
compared with those previously obtained in normal hips and were correlated
with diagnosis, topographical site, histology, and grading according to a
histological-histochemical technique previously described. The results
demonstrated surprisingly good preservation of cartilage and no significant
alteration in the biochemical and metabolic parameters. These findings
showed limited correlation with the topographical site and no correlation
with the cause of the necrosis or histological alteration. The results do
not support concepts of either accelerated metabolic activity or
chondrolytic change.
