研究背景全膝关节置换术是治疗晚期膝关节疾病的最佳方法，它能极大地缓解疼痛，恢复运动功能，提高生活质量。本研究回顾性调查了正常膝关节参数的影像学测量，并评估其临床value.MethodsBetween 2010年2月和2014年5月，并按照纳入标准，共677膝（334女膝和343男膝）分为3个年龄组。应用AutoCAD10.0软件测量胫骨平台后倾角、髌骨厚度、髌骨纵向长度和髌骨宽度等临床和X线数据。所有测量变量采用SPSS 18.0统计软件进行统计学分析。男性左右侧后倾角分别为6.78±3.43°和8.79± 3.44°，女性左右侧后倾角分别为5.42±3.19°和6.69±3.10 °。男性和女性的髌骨厚度、髌骨纵向长度和髌骨宽度分别为2.35±0.24 cm和2.11±0.20 cm、5.14±0.45 cm和4.67±0.35 cm、5.48±0.44 cm和4.88±0.41 cm。结果发现，青年组和中年组的后倾角在两侧之间有显著性差异（P0.01）。髌骨参数在膝关节两侧存在差异（P0.05），性别之间差异无统计学意义（P > 0.05）。结论本研究获得了大量的膝关节测量数据，并建立了当地正常膝关节数据库。全膝关节置换术前的影像学测量对于提高准确性和长期疗效具有重要的临床意义。这些数据对膝关节手术和运动医学也很有用。
BackgroundTotal knee arthroplasty is the optimal treatment for patients with advanced knee joint disease; it can greatly relieve pain, restore motion function, and improve life quality. This study retrospectively investigated the imaging measurement of normal knee parameters and evaluated their clinical value.MethodsBetween February 2010 and May 2014 and in accordance with the inclusion criteria, a total of 677 knees (334 female knees and 343 male knees) were categorized into 3 age groups. Clinical and X-ray data, including the posterior slope angle of the tibial plateau, patella thickness, longitudinal length of the patella and width of the patella, were measured by using AutoCAD 10.0 software. All measured variables were statistically analyzed by SPSS statistical software (version 18.0).ResultsData are presented as the mean±standard deviation. The male posterior slope angles on the left and right side were 6.78±3.43° and 8.79± 3.44°, respectively; the corresponding female measurements were 5.42±3.19° and 6.69±3.10,° respectively. For males and females, the patella thicknesses, longitudinal patella lengths and patella widths were 2.35±0.24 cm and 2.11±0.20 cm, 5.14±0.45 cm and 4.67±0.35 cm, and 5.48±0.44 cm and 4.88±0.41 cm, respectively. Based on the data obtained, we found that there were significant differences between two sides in terms of the posterior slope angles of young and middle-aged groups (P 0.01). The patella parameters showed difference between two sides of the knee (P 0.05), and no significant difference was observed between genders (P > 0.05).ConclusionIn this study, a large amount of knee measurements was obtained, and a local normal knee database was developed. Imaging measurements prior to total knee arthroplasty are clinically important for increasing the accuracy and long-term efficacy. These data can also be useful to knee surgery and sports medicine.
