Early detection of developing osteoarthritis by scintigraphy: an experimental study on rabbits.
Bone scintigraphy (99mTc-MDP) was used to study the development of experimental osteoarthritis produced by extension immobilization in rabbit knees. The purpose of the study was to determine a repeatable and noninvasive method for following the joint reaction leading to osteoarthritis. In comparison with the contralateral joints activity uptake in immobilized joints was already detectable in bone scintigraphy at 24 h, at the same time as the earliest changes in the biochemical reactions of joint tissues can be detected.
