The healing process of longitudinal lesions in the avascular region of the meniscus was investigated in 42 menisci from 21 dogs. A longitudinal incision was made in the avascular portion of the medial menisci of 21 dogs. In one knee, a flap of synovium was sutured into the wound, and in the other, the wound was sutured as a control. Animals were killed after 1 to 12 weeks, and the menisci were removed and examined by gross inspection, light microscopy, and microangiography. In the control knees, no healing had occurred. In 19 of 21 knees in which a synovial pedicle was used, the suture site did not open at any of the postoperative weeks. The longitudinal lesion was repaired with fibrovascular tissue at 6 weeks, and the vessels over the femoral surface of the menisci and an inner portion of the menisci had reached the suture site. The healing of meniscal lesion occurred due to the use of the vascularized synovial pedicle flap and the neovascularization from the parameniscal area.
对21只犬的42个半月板的半月板无血管区纵向损伤的愈合过程进行了研究。在21只犬的内侧半月板无血管部分做一个纵向切口。在一个膝关节中，将一片滑膜瓣缝合到伤口中，在另一个膝关节中，将伤口作为对照进行缝合。动物在1至12周后处死，取出半月板并通过大体检查、光学显微镜检查和微血管造影进行检查。在对照膝关节中，未发生愈合。在使用滑膜蒂的21个膝关节中的19个中，缝合部位在术后任何一周均未裂开。纵向损伤在6周时用纤维血管组织修复，半月板股骨表面和半月板内部的血管已到达缝合部位。半月板损伤的愈合是由于使用了带血管的滑膜蒂瓣以及半月板旁区域的新生血管形成。
