【Abstract】 Objective To study the conditions of injuries in the avascular area of menisci.Methods 48healthy rabbits randomly divided into three groups,including control group、FS-filled group、FGF-filled group and FGF/FS-filled group.Models of meniscus injuries in avascular area were established.The animals were killed in two,six,twelve weeks postoperatively and menisci were taken and observed both grossey and microscopically.Results FS being placed in the avascular portion of the menisci can result in scar-like tissue healing.No significant effect was seen in group of bFGF,but proliferation promoting reaction on fibroblastsin synovial membrane at the margin of menisci did exist.The lesion within the avascular portion of the meniscus can be healed by using FGF/FS.The reparˉative tissue is a fibrocartilagious tissue which is different from the normal tissue.Conclusion It may represent a poˉtential method of the avascular meniscal repair by placing the composite of FGF and FS.
