An objective clinical instrument known as a knee ligament Arthrometer was developed. The instrumentation system was applied to measurements of knee ligament laxity in the operating room with the patients under anesthesia. Prereconstruction and immediate postreconstruction measurements were made with the patient still on the operating table. The change in laxity of the patient's operated knee as compared to the opposite nonoperated control knee was documented for 19 chronic and 24 acute patients. Four separate reconstruction types were studied in the operating room. The immediate postreconstruction measurements documented that all four of the reconstruction types were equally effective in the immediate restoration of normal laxity in the ACL-deficient knees. The Arthrometer proved to be a useful tool for confirming that each patient's normal knee laxity was reestablished in the O.R. by its reconstruction.
一种名为膝关节韧带关节测量仪的客观临床仪器被研发出来。该仪器系统被应用于在手术室对处于麻醉状态的患者进行膝关节韧带松弛度的测量。在患者仍在手术台上时进行重建前和重建后的即时测量。记录了19名慢性患者和24名急性患者手术侧膝关节与对侧未手术对照膝关节相比的松弛度变化。在手术室研究了四种不同的重建类型。重建后的即时测量表明，所有四种重建类型在即刻恢复前交叉韧带缺失膝关节的正常松弛度方面同样有效。关节测量仪被证明是一种有用的工具，可用于确认每位患者的正常膝关节松弛度在手术室通过重建得以恢复。
