摘 要: | 目的 探讨膝骨关节炎( OA )患者髌骨下脂肪垫( IPFP)大小与软骨缺损之间的关系. 方法 收集174例膝OA患者,对患者一般情况行问卷调查,在核磁共振3D脂肪抑制T1加权回波序列上利用Osirix软件测量IPFP容积,在核磁共振T2加权质子密度加权快速自旋回波序列上对软骨缺损进行评级(0~4级),分析IPFP容积与软骨缺损之间的关系. 结果 放射性OA与非放射性OA患者IPFP体积差异无统计学意义;不同严重程度OA患者的IPFP体积差异有统计学意义(P<0. 05);OA患者IPFP体积与性别呈负相关性,与身高、体重呈正相关性,差异有统计学意义(P <0. 05);IPFP体积与膝关节内外侧股骨、外侧胫骨以及髌骨软骨缺损呈负相关性,差异有统计学意义( P<0. 05 ). 结论IPFP体积与软骨缺损及OA的病情严重程度相关, IPFP在OA发生发展中可能起保护作用.

Association between infrapatellar fat pad and cartilage defects in patients with osteoarthritis |

Abstract: | Objective To examine the association between infrapatellar fat pad ( IPFP) volume and cartilage de-fects in patients with knee osteoarthritis ( OA) . Methods 174 subjects participated in this study. The fat sup-pressed 3-dimensional T1-weighted spoiled gradient recall ( SPGR) magnetic resonance imaging ( MRI) was used to measure IPFP volume. T2-weighted fast spin echo MRI was utilized to assess cartilage defects. Results There was no significant difference in IPFP volume between patients with radiographic osteoarthritis and those without radio-graphic osteoarthritis. There were significant differences in IPFP volume among groups with mild, moderate and severe diseased groups ( P<0. 05 ) . IPFP volume was significantly and positively associated with height and weight ( P<0. 05 ) , and men had more IPFP volume than women ( P<0. 05 ) . There were significant and negative associ-ations between IPFP volume and cartilage defects at all sites except for medial tibial site ( P<0. 05 ) . Conclusion IPFP volume is negatively associated with cartilage defects severity in knee OA, suggesting that infrapatellar fat pad may play a protective role in knee OA. |
