Abstract:

BACKGROUND: Perfect preoperative preparation is essential, extremity X-ray measurement, CT three-dimensional reconstruction of the application, as well as computer aided technology all 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 collected 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). All the cases were followed-up at 3 monts, 1 and 2 years after total knee arthroplasty.
RESULTS AND CONCLUSION: After 3 months, 1 and 2 years follow-up, the knee function scores overall function and simple knee function of the CT three-dimensional reconstruction group were higher than those of the control group (P < 0.05). It will 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 will also help the patients to recover the force line and the function of the knee.
