| 目的 观察交叉韧带周围脂肪垫(PCFP)MRI表现与膝骨关节炎(KOA)严重程度的相关性。方法 回顾性纳入50例经MRI确诊KOA患者(KOA组)及30名健康人(对照组),观察MRI所示PCFP、髌下脂肪垫(IPFP)、股四头肌脂肪垫(QFP)及股前脂肪垫(PFP)信号强度变化。获取各自最大横截面积,评估KOA严重程度,包括膝关节软骨损伤、前交叉韧带撕裂、骨髓病变(BML)、半月板损伤及Park分级。比较组间脂肪垫MRI参数,分析PCFP参数与其他脂肪垫参数及KOA严重程度的相关性。结果 组间IPFP及PCFP信号变化分级差异有统计学意义(P均＜0.05);KOA组IPFP最大横截面积及PFP髌股间厚度均小于、而PCFP最大横截面积大于对照组(P＜0.05)。PCFP信号变化分级与IPFP信号变化分级呈正相关(rs=0.557),与PFP髌股间厚度呈负相关(rs=―0.651);PCFP最大横截面积与IPFP、PFP、QFP最大横截面积及QFP占位效应均呈正相关(rs=0.314~0.368);PCFP信号变化分级与膝关节各间室(髌股关节内、外侧,股骨内、外侧,以及胫骨内、外侧)软骨损伤均呈正相关(rs=0.502~0.735),PCFP最大横截面积与股骨外侧软骨损伤相关(rs=0.305)。此外,PCFP信号变化与前交叉韧带撕裂、BML、内侧半月板撕裂、外侧半月板撕裂、内侧半月板挤压、渗出性滑膜炎及Park分级均呈正相关(rs=0.425~0.789);PCFP最大横截面积与BML呈正相关(rs=0.313)。结论 PCFP MRI信号变化可提示KOA,且其分级与KOA严重程度相关。 |

| Objective To explore the relationships of MRI manifestations of pericruciate ligament fat pad (PCFP) with the severity of knee osteoarthritis (KOA). Methods Fifty patients with MRI diagnosed KOA (KOA group) and 30 healthy subjects (control group) were retrospectively included. Signal intensity changes of PCFP, infrapatellar fat pad (IPFP), quadriceps fat pad (QFP) and prefemoral fat pad (PFP) were observed, and the maximum cross-sectional areas were obtained. The severity of KOA was assessed, including knee cartilage injury, anterior cruciate ligament tear, bone marrow lesion (BML), meniscal injuries and Park classification. MRI parameters of fat pad were compared between groups, and correlations of PCFP MRI parameter and other fat pad MRI parameters with the severity of KOA were analyzed. Results Signal change grade of IPFP and PCFP were significant different between groups (both P＜0.05), and the maximum cross-sectional area of IPFP and the thickness of PFP patellofemoral in KOA group were smaller than, while the maximum cross-sectional area of PCFP in KOA group was larger than that in control group (all P＜0.05). The signal change grade of PCFP was positively related to signal change grade of IPFP (rs=0.557) but negatively related to PFP interpatellofemoral thickness (rs=―0.651). The maximum cross-sectional area of PCFP was positively related to the maximum cross-sectional area of IPFP, PFP and QFP, also to the QFP occupancy effect (rs=0.314 to 0.368). The signal change grade of PCFP was positively related to the cartilage injuries of knee compartments (medial and lateral patellofemoral joints, the femoral medial and lateral, the tibial medial and lateral) (rs=0.502 to 0.735), and the maximum cross-sectional area of PCFP was related to the lateral femoral cartilage injury (rs=0.305). In addition, the signal change grade of PCFP was positively related to tear of anterior cruciate ligament, BML, medial meniscus tears, lateral meniscus tears, medial meniscus extrusion, exudative synovitis and Park grading (rs=0.425 to 0.789), while the maximum cross-sectional area of PCFP was positively related to BML (rs=0.313). Conclusion MRI signal changes of PCFP could indicate KOA, and the grade of signal changes was correlated with the severity of KOA. |
