中文摘要:

目的:探讨3.0T MRI精确测量健康青年膝关节软骨厚度为骨关节炎的定量诊断和关节置换精准截骨提供可靠的解剖参数。

方法:自2013年1月至2013年12月于吉林省长春地区招募30名健康青年志愿者,男14名,女16名,年龄22~33(25.8±2.4)岁。对每名志愿者的双膝关节进行3.0 T MRI扫描,对股骨外侧髁(lateralis femoris condylus,LFC)、股骨内侧髁(medialis femorisc ondylus,MFC)、胫骨外侧平台(lateral tibial plateau,LTP)、胫骨内侧平台(medial tibial plateau,MTP)进行软骨厚度测量。

结果:在LFC、MFC、LTP、MTP 4个区域中,无论青年男性或女性,左、右侧膝关节软骨厚度比较,差异均无统计学意义(P>0.05);健康青年男性与女性之间膝关节软骨厚度比较,差异有统计学意义(P<0.05)。在同一性别组,LFC软骨厚度中间较薄,前、后方较厚;MFC软骨厚度前方最薄,从前方向后方逐渐增厚;LTP软骨厚度中间最厚,后方次之,前方最薄;MTP软骨厚度前方最薄,中间、后方相对均匀且均较前方厚。

结论:在我国22~33岁正常健康青年人中,性别差异可能是膝关节各个区域软骨厚度差异的重要因素。无论男性或女性健康青年人,整个膝关节软骨厚度分布不均匀,但左、右侧膝关节相同区域软骨厚度无明显差异。

Quantitative study of 3.0T MRI on the thickness of knee joint cartilage in healthy young people
ABSTRACT  

Objective To explore 3.0T MRI accurate measurement of knee cartilage thickness in healthy youth provides reliable anatomical parameters for quantitative diagnosis of osteoarthritis and accurate osteotomy of joint replacement.

Methods From January 2013 to December 2013,30 healthy young volunteers including 14 males and 16 females with an average age of (25.8±2.4) years old ranging from 22 to 33 years were recruited in Changchun,Jilin Province,and a 3.0T MRI scan was performed on the bilateral knee joints of each volunteer. The cartilage thickness was measured on the lateral femoral condyle (LFC),medial femoral condyle (MFC),lateral tibial plateau (LTP) and medial tibial plateau (MTP).

Results In four regions of the knee joint:LFC,MFC,LTP and MTP,whether young men or women,there was no significant difference in cartilage thickness between the left and right knee joints (P>0.05). There were significant differences in knee cartilage thickness between healthy young men and women (P<0.05). In the same sex group,LFC cartilage thickness was thinner in the middle,thicker in front and rear;MFC cartilage thickness was the thinnest in front and gradually thickening from the front to the rear; LTP cartilage thickness was thickest in the middle,second in the rear and thinnest in the front;MTP cartilage thickness was the thinnest in the front,was relatively uniform in the middle and rear and thicker than that in the front.

Conclusion In Northeast China,among healthy adults aged 22 to 33,gender difference may be an important factor in the difference of cartilage thickness in various regions of the knee joint. Regardless of whether male or female healthy young people,the cartilage thickness of the entire knee joint is unevenly distributed,but there is no significant difference in cartilage thickness in the same area between the left and right knee joints.
