Authors performed this study to validate the clinical usefulness of meniscal replacement using the autogenous periosteum and muscle fascia after meniscectomy in rabbits. The materials used for this study consisted of 28 rabbits, weighing between
1.8 and
2.5Kg. Animals were divided into 3 groups ; group I consisted of 4 rabbits and the other two groups consisted of 12 rabbits respectively.
In group I, as a control only right medial meniscus was removed. In group II the autogenous periosteum was transplanted after right medial meniscectomy. In group III the muscle fascia was transplanted after right medial meniscectomy.
The morphological and histological characteristics of the transplanted autografts were observed at various intervals from six to sixteen weeks postoperatively.
@ES The results were as follows.
@EN 1. The menisci were not regenerated at 6 and 9 weeks, the fibrous menisci attached was observed in group I at 12 and 16 weeks postoperatively.
2. The whitish to gray hard mass loosely attached to the synovium was observed at 6 weeks, and the contact surface of he mass to the femur was flattened at 16 weeks in group II. The irregular shaped soft thin mass loosely attached to the
synovium
was
observed at 6 weeks, and the consistency of the mass at 16 weeks was more hardened than that of 6 weeks in group III.
3. The dense fibrous connective tissue was observed at 6 weeks, and fibroblast, immatured chondroblast and dense fibrous connective tissue were observed at 6 and 12 weeks, and the fibrocartilagenous metaplasia was observed extensively at 16
weeks
in
group II. The fibrocartilagenous metaplasis was observed more extensively in group II than group III at 16 weeks postoperatively.
4. The fibrous tissue was observed at 6 weeks, and the fibrocartilagenous metaplasia was observed partially at 9 weeks in group III.
With above results, authors suggest the periosteal and mascle fascial autogroft use a meniscal replacement material.
We found the more usefulness of the periosteal autograft rather than fascial autograft after analyzing the experimental results.
