【Background and Objective】
We have created a rabbit osteoarthritis model by partial resection of the lateral meniscus of the left hind limb knee joint. This time, we created a cylindrical defect model of the meniscus by biopsy trepan using a Japanese white rabbit, and compared the condition of the meniscus and the condyle joint 28 days after the operation.
【Method】
A hole was made in the center of the medial meniscus of the right knee joint of 4 Japanese white rabbits weighing 2.9 to 3.4 kg using biopsy trepan (φ1.0 and 2.0 mm). The tibial condyle and meniscus were removed and visually observed.
【Result】
In the φ1 mm cylindrical defect model, the meniscus remained punctured.
The φ2 mm cylindrical defect model also had holes in the meniscus.
We compared the damage to the cartilage of the femoral condyle and tibial condyle with the partial meniscal resection model.
【Conclusion】
This model was also considered to be effective as a meniscus repair test.
