The long-term success of cementless total hip arthroplasty (THA) may depend on bone ingrowth into the porous-fixation surfaces of the implant. The ingrowth process is facilitated when the surgeon achieves a satisfactory fit for the prosthesis. Clinically or roentgenographically visible failure and persistent thigh pain after cementless THA remain significant problems, both of which may be alleviated by more precise preparation of the femoral canal and selection of an appropriately sized prosthesis. The objective of this study was to obtain an exact fit for the prosthesis through the use of an image-directed surgical robot for femoral canal preparation.
非骨水泥型全髋关节置换术（THA）的长期成功可能取决于骨长入植入物的多孔固定表面。当外科医生使假体达到满意的贴合度时，骨长入过程会得到促进。非骨水泥型THA术后临床上或影像学可见的失败以及持续的大腿疼痛仍然是重大问题，通过更精确地准备股骨髓腔和选择尺寸合适的假体，这两个问题都可能得到缓解。本研究的目的是通过使用图像引导手术机器人准备股骨髓腔，使假体获得精确的贴合度。
