- Brief Summary
With the apex of the deep cartilage (ADC) as the symbol, the consistency of the two methods in the postoperatively computed tomography (CT) and microscopic evaluation of the position of the femoral tract of the anterior cruciate ligament (ACL) was studied.Expected results:P1 and P2, D1 and D2 were positively correlated, and the linear relationship was significant. Bland-Altman diagram shows a good consistency.
- Detailed Description
Objectives:
With the apex of the deep cartilage (ADC) as the symbol, the consistency of the two methods in the postoperatively computed tomography (CT) and microscopic evaluation of the position of the femoral tract of the anterior cruciate ligament (ACL) was studied.
Methods:
Prospective cohort study.
Fifty-two patients requiring arthroscopic anterior cruciate ligament reconstruction were enrolled in the Sports Medicine Department of Peking University Third Hospital.
Collect patients' basic information and preoperative conditions. During the operation, the patient's knee was bent 90°, and the center point was positioned according to the intact femoral stump. The horizontal distance from the ADC to the anterior bone margin (L1) and the horizontal distance from the center point of the bone tract (L1) were measured by the master, the first aid and the second aid, and the distance from the center point of the bone tract to the lower bone margin (D1) was measured, and the ratio of L1 /L1 was calculated (P1).
The horizontal distance from the ADC to the anterior bone margin (L2) and the horizontal distance from the center of the bone tract (L2) were measured by three investigators on postoperative CT films, and the distance from the center of the bone tract to the lower bone margin (D2) was also measured, and the ratio of L2 /L2 was calculated (P2).
Linear regression, Pearson correlation and Bland-Altman analysis were used to compare the consistency between the endoscopic assessment and CT assessment.
Expected results:
P1 and P2, D1 and D2 were positively correlated, and the linear relationship was significant. Bland-Altman diagram shows a good consistency.
