Twelve patients with cystic degeneration of the lateral meniscus were submitted to magnetic resonance and arthroscopy. This study showed that mixoid degeneration is produced initially within the meniscal substance and subsequently progresses towards and may rupture through the outer margin, so producing the clinically detectable cyst on the outer margin of the joint. In the light of the information obtained from magnetic resonance and subsequent surgical verification, existing hypotheses regarding the pathogenesis and evolution of the lesion have been re-examined.
12例外侧半月板囊肿变性患者接受了磁共振成像和关节镜检查。本研究表明，黏液样变性最初在半月板实质内产生，随后向外侧边缘发展并可能破裂，从而在关节外侧边缘形成临床上可检测到的囊肿。根据磁共振成像获得的信息及随后的手术验证，对有关该病变发病机制和演变的现有假说进行了重新审视。
