Research progress of medial collateral ligament injury of knee joint
The medial collateral ligament(MCL)of the knee joint is the main static stabilizer of the me-dial knee joint,which provides important support for the knee joint to resist valgus and rotational forces.MCL is the most common injury in knee joint movement.Injury can lead to medial instability of the knee joint,and severe cases may eventually cause secondary osteoarthritis,which has a negative impact on the prognosis of patients.This article reviewed the anatomy,function,injury grading,diagnosis and treatment of MCL,aiming to provide reference for clinical diagnosis and treatment of MCL.
