Intervention
femoral head, THA
A total of 60 patients were randomly divided into two groups: patients who underwent conventional THA (cTHA group) and patients who underwent robotic arm-assisted THA (rTHA group). The patients in the cTHA group underwent preoperative planning, during which the pelvic digital X-ray (enlarged by 100%) was compared to a two-dimensional digital model of the prosthesis. Conversely, patients undergoing rTHA had preoperative CT scans of the pelvis and both knees, in which the pelvic CT was compared to a three-dimensional digital model of the prosthesis using a robotic navigation system for precise implant positioning (Fig. Preoperative planning with computer for robotic arm-assisted total hip arthroplasty. 手术规划, surgical planning; 髋臼杯, acetabular cup; 内衬, acetabular liner; 球头, femoral head; 柄类型, stem type; 股骨柄, femoral stem
