A two-dimensional model of the tibio-femoral joint was constructed by using the results of cadaver knee dissections together with radiographic landmarks on healthy knees loaded at various angles of flexion. The tibio-femoral compressive force during isometric knee extension had the same magnitude as the patellar tendon force. The tibio-femoral shear force changed direction from posterior at full flexion to anterior when the knee was extended, indicating that high forces may arise in the anterior cruciate was extended, indicating that high forces may arise in the anterior cruciate ligament in the straight knee. Women developed some 20 per cent higher knee joint forces than men for the same extending muscular moment higher knee joint forces than men for the same extending muscular moment, since women's patellar tendon moment arms were found to be shorter. The model presented may be used for quantifying tibio-femoral forces during knee extending activities.
通过利用尸体膝关节解剖结果以及在不同屈曲角度加载的健康膝关节的放射学标志，构建了胫股关节的二维模型。等长伸膝过程中胫股关节的压缩力大小与髌腱力相同。胫股关节的剪切力在膝关节完全屈曲时向后，而在膝关节伸展时向前，这表明在伸直膝关节时前交叉韧带可能会承受较大的力。对于相同的伸肌力矩，女性产生的膝关节力比男性高约20%，因为发现女性的髌腱力臂较短。所呈现的模型可用于量化膝关节伸展活动期间的胫股关节力。
