Post-meniscectomy knees examined with an instrumented clinical testing device reveal that meniscectomy alone does not cause a measurable degree of instability. If meniscectomy causes a minor degree of instability, the degree is within the right-left variation for a normal population. Medical meniscectomy in combination with a torn anterior cruciate results in an increased anterior-posterior instability at 20 degrees knee flexion. The device used in this study was more reliable in diagnosing increased anterior-posterior instability secondary to anterior-cruciate tear than was a clinical examiner.
使用仪器化临床测试设备检查半月板切除术后的膝盖发现，单纯半月板切除术不会导致可测量程度的不稳定。如果半月板切除术导致轻微程度的不稳定，该程度也在正常人群左右变化范围内。内侧半月板切除术合并前交叉韧带撕裂会导致在膝关节屈曲20度时前后不稳定增加。本研究中使用的设备在诊断继发于前交叉韧带撕裂的前后不稳定增加方面比临床检查者更可靠。
