The Orthopädische Arbeitsgruppe Knie (OAK) documentation is based on clinical evaluation during functional knee stability testing near extension and near flexion. Increased compartmental translations and rotations, which result from structural defects because of anatomic lesions in a given knee injury, are clinically evaluated. The synopsis of the clinically detectable abnormal knee motion is graphically documented. A clinically applicable grading system of the true and reversed pivot shift phenomena completes the assessment of compartmental knee instability. Important contributing factors such as the constitutional laxity, the morphotype, and the range of motion are registered on the documentation form. The evaluation form presents four categories that represent subjective, objective, and functional criteria reflecting the overall results of repaired ligaments. This evaluation format establishes selected criteria to compare results from different centers.
膝关节矫形工作组（OAK）的文档基于在膝关节接近伸直和接近屈曲时进行功能稳定性测试期间的临床评估。对因特定膝关节损伤中的解剖病变导致的结构缺陷而引起的关节间平移和旋转增加进行临床评估。临床上可检测到的异常膝关节运动的概要以图形方式记录。真正的和反向的轴移现象的临床适用分级系统完善了膝关节间不稳定的评估。诸如体质松弛、形态类型和活动范围等重要影响因素记录在文档表格上。评估表呈现了四类内容，代表反映修复韧带总体结果的主观、客观和功能标准。这种评估形式确立了选定的标准，以便比较不同中心的结果。
