A longitudinal tear was made and then sutured in the peripheral quarter of the medial meniscus of 43 dogs. The sutured menisci were examined using histologic and microangiographic techniques at regular intervals during a 12-week period. Biomechanical tests were also performed. The healing process was promoted not only by the synovial blood supply but also by the peripheral blood supply. Even at the end of 12 weeks, the healing tissue was mainly composed of fibrous tissue, but chondrocytelike cells were also found. The tensile forces were calculated and compared with the opposite leg. The maximum tensile strength reached 80% of that of the opposite side at the end of the 12-week period.
在43只犬的内侧半月板外周四分之一处制造纵向撕裂伤，然后进行缝合。在12周的时间内，定期使用组织学和微血管造影技术检查缝合后的半月板。还进行了生物力学测试。愈合过程不仅由滑膜血供促进，也由外周血供促进。即使在12周结束时，愈合组织主要由纤维组织组成，但也发现了软骨样细胞。计算拉伸力并与对侧腿进行比较。在12周结束时，最大拉伸强度达到对侧的80%。
