Cadaver knee joints were mounted so that life-like forces of weight-bearing were simulated. The patello-femoral contact areas were defined under load throughout the range of movement by the dye method. During movement from extension to 90 degrees of flexion a band of contact sweeps across the patella from inferior to superior pole, but the odd facet makes no contact. At about 135 degrees of flexion separate medial and lateral contact areas form, the medial one limited to the odd facet. From extension to 90 degrees of flexion the patella holds the quadriceps tendon away from the femur, but in further degrees of flexion an extensive "tendo-femoral" contact area forms. Between 90 degrees and 135 degrees of flexion the patella rotates and the ridge between the medial and odd facets engages the femoral condyle. The odd facet is shown to be a habitual non-contact area and the ridge to be subject to high load, observations which correlate with cartilage lesions described in Part 2 of the paper.
将尸体膝关节进行安装，以模拟逼真的负重力量。通过染色法在整个运动范围内的负荷下确定髌股接触区域。在从伸展到90度屈曲的运动过程中，一条接触带从髌骨的下极向上极扫过，但奇数小面不接触。在大约135度屈曲时，形成单独的内侧和外侧接触区域，内侧区域仅限于奇数小面。从伸展到90度屈曲时，髌骨使股四头肌腱远离股骨，但在进一步屈曲时，形成一个广泛的“肌腱 - 股骨”接触区域。在90度到135度屈曲之间，髌骨旋转，内侧和奇数小面之间的嵴与股骨髁相接合。奇数小面被证明是一个习惯性非接触区域，而嵴承受高负荷，这些观察结果与本文第2部分中描述的软骨损伤相关。
