Total medial meniscectomy was carried out on 30 mature rabbits; subsequent regeneration of the meniscus and degenerative joint changes were observed. Out of 30 knees, 22 had regenerated menisci and 10 of these had not developed gross degenerative changes after 6 months. Collagen fibres were arranged irregularly in the regenerated menisci, although in some areas they occurred in parallel. Every type of mechanoreceptor was found in the outer third of the normal menisci, and in the middle and outer third of the regenerated menisci with no statistical difference in numbers. Mechanoreceptors can regenerate in regenerated menisci and may protect the join from degeneration.
对30只成年兔进行了内侧半月板全切除术；随后观察半月板的再生情况和关节退变变化。在30个膝关节中，22个有半月板再生，其中10个在6个月后未出现明显的退变变化。再生半月板中的胶原纤维排列不规则，不过在一些区域它们是平行排列的。在正常半月板的外三分之一以及再生半月板的中三分之一和外三分之一中均发现了每种类型的机械感受器，其数量无统计学差异。机械感受器可在再生半月板中再生，并可能保护关节免于退变。
