为了评估日本患者全膝关节置换术中胫骨部件旋转中立对准标志的可靠性，通过计算方法测量了 24 个患有内侧股胫骨关节炎的膝关节和 28 个正常膝关节的胫骨结节内侧 ⅓ 相对于股骨上髁线（角度 TT）和相对于踝关节中心（角度 TT-AA）的旋转位置。断层扫描。 TT-AA角显示胫骨内侧扭转的程度。角度TT和角度TT-AA的范围均大于40°。胫骨结节的位置和胫骨内侧扭转的程度因人而异。对于患有严重内侧扭转的患者，如果使用胫骨结节的内侧 ⅓ 来对部分受限的胫骨假体进行旋转中立对齐，则足部的内旋会非常严重。特别是在治疗东亚国家的患者时，全膝关节置换术中应考虑胫骨内侧扭转，以确保股骨内侧骨关节炎患者膝盖内髌骨的正确跟踪和足部的正确旋转。
To assess the reliability of the landmarks for the rotationally neutral alignment of the tibial component in total knee arthroplasty for Japanese patients, the rotational position of the medial ⅓ of the tibial tuberosity relative to the femoral epicondylar line (Angle TT) and that relative to the center of the ankle (Angle TT-AA) were measured in 24 knees with medial femorotibial osteoarthritis and in 28 normal knees by computed tomography. Angle TT-AA shows the degree of medial torsion of the tibia. The range of Angle TT and that of Angle TT-AA each was greater than 40°. The position of the tibial tuberosity and degree of medial torsion of the tibia varied by individual. In patients with severe medial torsion, the internal rotation of the foot is extreme if the medial ⅓ of the tibial tuberosity is used for the rotationally neutral alignment of the partially constrained tibial component. In the treatment specifically of patients from East Asian countries, medial torsion of the tibia should be taken into account in total knee arthroplasty to ensure proper patellar tracking and proper rotation of the foot in knees with medial femorotibial osteoarthritis.
