Objective To compare the difference in articular cartilage degeneration between xenogenic medial meniscus transplantation and total medial meniscectomy in order to understand whether xenogenic medial meniscus transplantation could delay the degeneration of articular cartilage.

Objective To study the type Ⅰ,Ⅱ,Ⅲ and Ⅹcollag e n expression in meniscus and articular cartilage and immunoreactions post xenoge nic and allogenic meniscus transplantation.
