Total knee replacement (TKA) , an important surgical technique for end-stage osteoarthritis, has achieved good long-term results and prosthesis survival rate. Currently, cruciate retaining (CR) and posterior stabilized (PS) prostheses are the main types of TKA commonly used in clinical practice. However, the anterior cruciate ligament (ACL) must be removed during the implantation of both CR and PS prostheses in TKA. ACL is an important location of knee proprioception receptors. The removal of ACL will lead to changes in knee pro- prioception and motion mechanics, cause the subjective feelings inefficient. The bicruciate-retaining (BCR) knee can best simulate natural knee motion mechanics, has attracted renewed attention recently.
