CONCLUSION

The discoid meniscus can be divided into seven layers in a symmetrical manner with the central layer as an axis, with an exception of the surface layer, which shows a difference between the femoral and the tibial surfaces.

All layers have their own unique fibrillar orientations. The central layer seems to play a main role in resisting hoop tension since the peripheral portion has circumferential fashion of collagen fibers. Therefore, we can consider that preservation of the peripheral edge of the discoid meniscus would be better when resection of meniscus is mandatory.

결 론: 외측 원판형 연골은 대퇴골 관절면으로부터 경골 관절면으로 7개 층으로 나눌 수 있으며 대퇴골과 경골의 표면층을 제외하고 중심층을 축으로 하여 위 아래로 서로 대칭 되는 층으로 되어있다. 각 층의 교원 섬유는 모두 각자의 특징을 가지고 있으며 그 중에 서 중심층의 변연부에는 굵은 다발 형태를 가진 환형으로 배열된 교원 섬유가 존재하므 로 hoop tension에 잘 적응하는 기능을 수행함에 있어서 가장 중요한 부분으로 사료된 다. 이에 원판형 연골 파열의 치료에서 절제술을 시행할 때 변연부 부분을 환형으로 남 겨두는 것은 필수적이라고 사료된다.
