Following description of a model which can be applied in clinical practice for planning an operation with regard to the load and strain placed on the hip joint, as expounded in previous articles, the present article explains two more realistic possibilities of calculation of the pressure on the joint. We now have, therefore, three pressure models which can be compared with each other: 1. Assumption of equal distribution of the pressure over the hip joint with calculation of the maximal pressure. 2. Assumption of a linear drop in pressure from the acetabulum in the direction of the floor of the acetabulum. 3. Assumption that the articular cartilage displays an ideally elastic behaviour (calculation of pressure according to Hooke's Law). The last-named model No. 3 is probably the most realistic one, but in view of the fact that it requires complicated calculations, it will be employed in specific cases only, which will usually be mostly of a theoretical nature; Model No. 1 requires a reasonable amount of calculation and will suffice, as shown in the present article, for daily routine surgical planning.
如前文所述，在描述了一种可应用于临床实践的模型后，该模型用于根据髋关节所承受的负荷和应变来规划手术，本文阐述了另外两种更符合实际的关节压力计算方法。因此，我们现在有三种可以相互比较的压力模型：1. 假设髋关节上压力均匀分布并计算最大压力。2. 假设压力从髋臼向髋臼底部方向呈线性下降。3. 假设关节软骨表现出理想的弹性行为（根据胡克定律计算压力）。最后提到的模型3可能是最符合实际的，但鉴于它需要复杂的计算，通常只会在特定情况下使用，而这些情况大多是理论性的；模型1需要进行一定量的计算，并且如本文所示，对于日常手术规划来说已经足够。
