摘要
目的测量适合全膝关节置换术(TKA)治疗的大骨节病性膝关节炎患者相关X线指标,为临床上采用TKA提供帮助。方法选取93例膝关节,分为大骨节病性膝关节炎组、膝关节退行性骨关节病组和正常对照组,拍摄膝关节正位X线片,用AutoCAD10.0软件标识并测量相关指标:股骨内外髁横径、胫骨平台横径、胫骨平台内翻角(PT角)、小腿机械轴垂直线与双侧股骨髁远端切线的夹角(FT角)。结果股骨内外髁横径:大骨节病性膝关节炎组女性与正常对照组女性相比差异有统计学意义;胫骨平台横径和PT角:膝关节退行性骨关节病组女性及正常组女性相比差异均有统计学意义;FT角:各组与正常对照组同性别相比差异均有统计学意义;PT角和FT角在与国外数据的比较上差异均有统计学意义。结论适合TKA治疗的大骨节病性膝关节炎患者的膝关节测量数据有一定特异性,可为设计适合该病的人工膝关节假体、提高TKA精确度与成功率及远期疗效提供理论依据。
Objective To investigate the X-ray imaging measurement of Kaschin-Beck disease（KBD） knees in aged people which fit for total knee arthroplasty（TKA） and its clinical significance.Methods A total of 93 knees were divided into KBD group,degenerative osteoarthropathy group and normal control group.Their clinical and X-ray data（anterioposterior view） were collected.The indexes of femoral condyle diameter,tibial plateau diameter,angle PT and angle FT were measured by AutoCAD 10.0.Results The femoral condyle diameter of female KBD group had statistical significance compared with that of normal female group.The tibial plateau diameter and angle PT of female degenerative osteoarthropathy group had statistical significance compared with those of normal female group.Angle FT of KBD group and degenerative osteoarthropathy group had statistical significance compared with that of normal control group of the same sex.Compared with foreign data,angle PT and angle FT had statistical significance.Conclusion The imaging measurement of KBD knees which fit for TKA has specificity.This can provide a theoretical basis for designing the knee prosthesis and increasing the accuracy,success rate and long-term efficacy of TKA.
