The Relationship Between Passive Joint Laxity and Functional Outcome After Anterior Cruciate Ligament Injury

摘要: Twenty patients with anterior cruciate ligament-deficient knees were studied. Ten returned to all sports activities (compensators) and 10 not improved nonoperative management required surgical stabilization (noncompensators). Joint laxity was measured using a KT-2000 arthrometer (manual maximum Lachman). Subjects completed Lysholm questionnaire Knee Outcome Score. The International Documentation Committee form also completed. Patients rated their knee function on scale of 1 100. There no difference in level frequency athletic activity between the two groups before ligament injuries as determined by outcome score. compensator group had mean side-to-side 3.25 mm at 89 N noncompensators 3 preoperatively. Manual tests gave differences 6.7 for compensators 6 noncompensators. measures groups. correlation scores measurements significant. Measurements correlated functional used this study. Functional that are partially based joint measures, such form, may artificially overestimate disability after rupture.
