摘要:Medial collateral ligament (MCL) of the knee can maintain the joint stability and movement. MCL injuries often occur in car accident and sports. Improper treatment may lead to severe knee dysfunction. The injury classification is refined. By MRI, the MCL fracture position and associated injuries can be found, which is helpful to make the treatment plan. There are many therapeutic methods for MCL injuries of the knee. And currently the treatment with semitendinosus and gracilis transport to repair MCL gets satisfactory curative results. Through reviewing the diagnosis, therapeutic methods and curative effects of MCL injuries of the knee, it is found that the treatment with semitendinosus and gracilis transport to repair MCL could fully play the inherent biological effect of MCL.
