Total hip arthroplasty (THA) is the primary treatment for end-stage hip diseases, and its clinical outcomes mainly depend on the accuracy of prosthesis implantation. Robot-assisted THA (RTHA), with its advantages in prosthesis implantation, overcomes the uncertainty of component positioning in conventional surgery and has become a research hotspot in joint surgery in recent years. This article systematically reviews international RTHA systems such as ROBODOC and MAKO, as well as domestic RTHA systems including the ARTHROBOT Joint Replacement Surgical Robot and the LONGWELL THA Surgical Robot, comparing their technical characteristics and clinical application status. It also explores the medical application of industrial robotic arms such as WAM, KUKA, and UR and their innovative applications in THA, aiming to provide reference for the future development and clinical application of RTHA systems.
