背景：大骨节病（KBD）是一种罕见的变形性地方性骨关节病。全膝关节置换术（TKA）是晚期大骨节病患者的最佳治疗方法，可以极大地缓解疼痛、恢复运动功能、提高生活质量。本文回顾性研究了大骨节病患者膝关节参数的数字化X线成像测量及其临床意义。方法：将93个膝关节分为3组：大骨节病组、退行性骨关节病组和正常组。采用AutoCAD 10.0测量股骨髁直径、胫骨平台直径、后斜角、内侧胫骨平台与腓骨头之间的距离（DPF）、髌骨厚度、髌骨长度和髌骨宽度等临床和影像数据。结果：正常组中，男性和女性股骨髁直径分别为7.34 cm和6.64 cm；胫骨平台直径分别为7.54 cm和6.90 cm；后倾角分别为7.30°和10.91°； DPF为1.44厘米和0.81厘米；髌骨厚度分别为2.05厘米和1.79厘米；髌骨长度分别为4.34厘米和3.82厘米；髌骨宽度分别为4.90厘米和4.31厘米。数据显示，与同性别正常组相比，大骨节病组的后坡角、股骨髁和胫骨平台直径均值较大，但男性 DPF 较短。结论：KBD膝关节的影像学测量具有重要的临床意义，有助于提高TKA的准确性，这些数据也为膝关节手术、影像诊断提供了有用的信息。
Background: Kaschin-Beck disease (KBD) is a rare deforming endemic osteoarticular disease. Total knee arthroplasty (TKA) is the optimal approach for patients with advanced KBD, as it can greatly relieve pain, restore motion function, and improve life quality. This paper retrospectively investigated the digital X-ray imaging measurement of knee parameters of KBD patients and their clinical significance. Methods: A total of 93 knees were categorized into 3 groups: KBD group, degenerative osteoarthropathy group and normal group. Clinical and imaging data including femoral condyle diameter, tibial plateau diameter, posterior slope angle, distance between medial tibial plateau and fibular head (DPF), patella thickness, length of patella and width of patella were measured by AutoCAD 10.0. Results: In normal group, the femoral condyle diameter of males and females was 7.34 cm and 6.64 cm, respectively; the tibial plateau diameter was 7.54 cm and 6.90 cm; the posterior slope angle was 7.30° and 10.91°; DPF was 1.44 cm and 0.81 cm; patella thickness was 2.05 cm and 1.79 cm; the patella length was 4.34 cm and 3.82 cm; the patella width was 4.90 cm and 4.31 cm. Based on the data, the KBD group had greater mean of posterior slope angle, femoral condyle and tibial plateau diameter compared with normal group of the same gender, but shorter male DPF. There were significant differences between the KBD group and normal group in female posterior slope angle, and male DPF (P P Conclusion: The imaging measurement of KBD knees is of great clinical significance, and it will help to increase the accuracy of TKA. These data also provide useful information for knee surgery, and imaging diagnosis.
