Loadbearing stresses in the patellofemoral joint were studied at different degrees of flexion before and after various surgical techniques recommended to treat knee disorders. Surgical procedures intended to reduce the intensity of stress were analyzed experimentally. The study was done using different experimental methods on whole knee specimens from fresh human cadavers that were not treated with formaldehyde. The results indicate that the most predictable procedure for increasing surface area and decreasing patellar stress is a combined procedure of anterior displacement of the anterior tibial tubercle by 1 cm while displacing it 0.5 to 1 cm medially.
在推荐用于治疗膝关节疾病的各种手术技术前后，研究了不同屈曲程度下髌股关节的承重应力。对旨在降低应力强度的手术程序进行了实验分析。该研究采用不同的实验方法，对未经甲醛处理的新鲜人类尸体的全膝关节标本进行。结果表明，增加表面积和降低髌股应力最可预测的手术是将胫骨结节向前移位1厘米并向内移位0.5至1厘米的联合手术。
