[Application of passive image-free navigation system for total knee arthroplasty].
2019
: Total knee arthroplasty(TKA) has been the final clinical treatment of knee osteoarthritis at the final stage, postoperative limb and prosthesis alignment restoration directly affect clinical effect. In recent years, computer-assisted surgery has been used in TKA and obtained satisfied results. There paper has investigated that the use of computer-assisted systems could improve soft tissue balance after TKA, improve accuracy of installation of prosthesis, recover limb alignment and decrease intro-blood loss, postoperative fat embolism. Although computer-assisted navigation is not mainstream, with the continuous improvement of technology and innovation, the computer-assisted surgery could exert a more important role in TKA, and considerably beneficial effect on improvement of postoperative clinical effects.
