Total knee arthroplasty(TKA)is the main treatment for the end-stage knee diseases currently.However,whether the knee prosthesis is loose has become a decisive factor to determine the success or failure of the surgical procedure,and the bone loss around the prosthesis has become an important evaluation basis.In addition,bone mass loss usually occurs in early stage secondary to TKA,which is highly correlated with implant design,surgical technique,bone loading status,and functional exercise.Despite advances in implant design and surgical techniques,TKA is still at high risk of loosening the implant.In this paper,the stress transfer mechanism,particles,inflamma-tion,evaluation of bone loss around the prosthesis,and repair criteria after prosthetic implantation were reviewed,so as to provide reference for the prevention of prosthetic loosening in clinical settings.
