背景:下肢 X 射线测量及 CT 三维重建的应用,以及计算机辅助技术都有助于人工全膝关节置换术者更精确地安放假体.目的:探讨全膝关节置换前 CT 三维重建确定股骨髓内定位杆置入点对置换后关节功能的影响.方法:32例全膝关节置换患者,其中置换前进行 CT 三维重建确定股骨髓内定位杆置入点的18个病例(CT 三维重建组),其余病例术前未进行 CT 三维重建(对照组),在置换后3个月、1年、2年定期随访.结果与结论:置换后3个月、1年、2年随访与对照组比较,CT 三维重建组膝关节功能评分总体功能和单纯膝关节功能评分显著增高(P 均<0.05).提示全膝关节置换前行膝关节 CT 三维重建确定股骨髓内定位杆进入点有助于在置换中正确插入股骨髓内定位杆,更准确地进行股骨端的截骨以及膝关节假体的安放,能够更好地恢复下肢力线和膝关节的功能.

BACKGROUND: Perfect preoperative preparation is essential, extremity X-ray measurement, CT three-dimensional reconstruction of the application, as wel as computer aided technology al contribute to the patients for more accurately placed prosthesis. OBJECTIVE: To discuss the value of femur marrow rod insertion point determined by preoperative CT three-dimensional reconstruction on knee function after total knee arthroplasty. METHODS: Thirty-two patients with total knee arthroplasty were col ected to review. Among the 32 patients, 18 patients received CT three-dimensional reconstruction preoperatively to locate the femur marrow rod insertion point (CT three-dimensional reconstruction group), and the other patients did not receive the CT three-dimensional reconstruction (control group). Al the cases were fol owed-up at 3 monts, 1 and 2 years after total knee arthroplasty. RESULTS AND CONCLUSION: After 3 months, 1 and 2 years fol ow-up, the knee function scores overal function and simple knee function of the CT three-dimensional reconstruction group were higher than those of the control group (P <0.05). It wil be much more effective to insert the femur marrow navigation rod and much more accurate to process the distal femur osteotomy and place the knee prosthesis through the CT three-dimensional reconstruction to measure and locate the femur marrow rod inserting points before the total knee arthroplasty. It wil also help the patients to recover the force line and the function of the knee.
