Measuring the knee relaxation regardless of the use of additional means of magnetic resonance imaging such as X-rays and axial tomography, ligaments any, ie, orthonormal, forward, backward, internal, invention, before the external front the rear inner and the reference axis of the rear external, internal capsule cruciate ligament, posterior cruciate ligament, the posterior, evaluated and instability of the knee due to rupture of the envelope of the rear front, and a three parts, and respectively, thighs, legs, and a device (1) for receiving and holding foot. The device (1), independent means to push back the areas of the front leg (20), independent means to push forward region of the rear leg (21), fixing parts and support foot (5) I and a (13) independent means to push in the direction of the counterclockwise independent means to press in a clockwise direction (12), fixing parts and support of the foot (5). [Selection] Figure Figure 1本発明は、X線体軸断層撮影及び磁気共鳴映像法等の付加的な手段の使用に関わらず膝弛緩を測定し、任意の靭帯、すなわち、正規直交、前方、後方、前内部、前外部、後内部、及び、後外部の基準軸周りに、前十字靭帯、後十字靭帯、後部の内包、後部の外包の断裂による膝の不安定性を評価し、そして、3つのパーツを備え、それぞれ、大腿部、脚、及び足を受けて保持するデバイス(1)に関する。デバイス(1)は、脚の前部の領域を後方に押す独立手段(20)と、脚の後部の領域を前方に押す独立手段(21)と、足の支持及び固定用パーツ(5)を時計周りの方向に押す独立手段(12)と、足の支持及び固定用パーツ(5)を反時計周りの方向に押す独立手段(13)とを備える。【選択図】図1
