Arthrometry was performed before and during anesthesia in 41 patients with acute or old anterior cruciate ligament injuries and only minor signs of valgus or varus instability. The uninjured contralateral knee served as a control. The influence of anesthesia on the anterior stability was distinct in acute knee injuries. There was also a small, but definite, increase in anterior laxity in uninjured knees. Knees with old injuries were more lax, and the injured-uninjured difference in anterior laxity was more pronounced. Stability examination under anesthesia is of great value for acutely injured knees.
对41例急性或陈旧性前交叉韧带损伤且仅有轻微外翻或内翻不稳定体征的患者，在麻醉前及麻醉过程中进行了关节测量。未受伤的对侧膝关节作为对照。麻醉对急性膝关节损伤的前向稳定性影响明显。未受伤的膝关节前向松弛度也有小幅但确定的增加。陈旧性损伤的膝关节更松弛，且受伤与未受伤膝关节在前向松弛度上的差异更显著。麻醉下的稳定性检查对急性损伤的膝关节具有重要价值。
