The right hind limbs of adult rabbits were immobilized for 5 weeks. The rabbits were then allowed to move freely for 8 weeks. The rabbits of the control group were immobilized uninterruptedly. In a second group of rabbits the plaster was removed during the immobilization period 6 days a week for 5 minutes for careful exercise and in a third group of rabbits, for violent exercise. The temporary careful exercise was of no benefit and was sometimes harmful, and the violent exercise was usually injurious for the immobilized knees as regards the stiffening, thickening and the development of radiologically detectable degenerative changes.
成年兔的右后肢被固定5周。然后让兔子自由活动8周。对照组的兔子持续固定。第二组兔子在固定期内，每周6天去除石膏，进行5分钟的仔细运动；第三组兔子进行剧烈运动。临时的仔细运动没有益处，有时还有害，而剧烈运动通常会对固定的膝盖造成伤害，导致僵硬、增厚以及出现放射学可检测到的退行性变化。
