研究概览
简要总结
This prospective study will evaluate whether tourniquet inflation affects the results of the pivot shift test in patients undergoing anterior cruciate ligament (ACL) reconstruction. The pivot shift test is commonly used to assess rotational instability of the knee in patients with ACL injury.
In each participant, the pivot shift test will be performed under anesthesia before and after inflation of the thigh tourniquet, allowing the two conditions to be compared within the same patient. The study aims to determine whether tourniquet use changes the findings of the pivot shift examination.
Understanding the possible influence of tourniquet inflation may help standardize intraoperative assessment of rotational knee instability and improve interpretation of the pivot shift test during ACL surgery.
详细描述
Anterior cruciate ligament (ACL) deficiency may result in both anterior and rotational instability of the knee. The pivot shift test is commonly used to assess rotational instability and is frequently performed under anesthesia during ACL reconstruction. However, intraoperative factors may influence the findings of the examination.
This prospective study is designed to investigate whether inflation of a thigh tourniquet affects the pivot shift test. Each participant will serve as their own control. After induction of anesthesia, the pivot shift test will be performed before tourniquet inflation and repeated after tourniquet inflation under the same operative conditions. The findings obtained under the two conditions will be compared to determine whether tourniquet inflation influences the assessment of rotational knee instability.
The study may help clarify whether tourniquet status should be standardized when the pivot shift test is performed intraoperatively during ACL reconstruction.

研究组 & 干预措施
Tourniquet Assessment Group
Participants undergoing anterior cruciate ligament reconstruction will undergo the pivot shift test under anesthesia before and after inflation of the thigh tourniquet during the same surgical procedure. Each participant will serve as their own control, and the paired assessments will be compared to determine whether tourniquet inflation influences the pivot shift test findings.
干预措施: Thigh Tourniquet Inflation (Procedure)
结局指标
主要结局
Change in Pivot Shift Test Grade After Tourniquet Inflation
时间窗: Intraoperatively, immediately before and after tourniquet inflation
The pivot shift test will be performed under anesthesia immediately before and after inflation of the thigh tourniquet. Pivot shift grade will be recorded using the standard clinical grading system. Pre-inflation and post-inflation grades will be compared within the same participant to determine whether tourniquet inflation changes the degree of rotational knee instability. Higher grades indicate greater rotational instability.
