| 目的 采用高频超声和X线平片检查,探讨膝关节骨关节炎半月板突出与骨关节炎严重程度的相关性。 方法 选择50例临床诊断骨关节炎患者,共71个有症状膝关节(骨关节炎组)。另选择年龄匹配的10名无膝关节症状的健康志愿者作为对照组,共15个膝关节。骨关节炎组与对照组均接受高频超声及X线平片检查,超声观察内侧半月板突出的程度;同时对所有膝关节平片进行KL评分,并将内侧半月板突出程度同KL评分进行对照分析。 结果 骨关节炎组71个膝关节中,高频超声检出52个膝关节存在内侧半月板突出,其中轻度突出17个,中度突出24个,重度突出11个。骨关节炎组所有X线检查均有异常,其中12个膝关节KL评分为1;26个为2;21个为3,12个为4。对照组中,高频超声检出3个膝关节有内侧半月板突出,均为轻度突出;其中2个KL评分为1,其余X线表现正常。内侧半月板突出的发生率骨关节炎组明显高于对照组(χ2=15.23,P＜0.001)。内侧半月板突出程度同KL评分存在线性相关(χ2=27.01,P＜0.001)。 结论 内侧半月板突出是膝关节骨关节炎患者超声表现中的一个重要征象,并与骨关节炎的平片分级相关。 |

| Objective To access the association between meniscal protrusion and severity of knee osteoarthritis with high frequency ultrasonography and X-ray. Methods Seventy-one knees of 50 patients with osteoarthritis and 15 knees of 10 controls matched in age were examined with radiography and high frequency ultrasonography. The degree of meniscal protrusion was evaluated using high frequency ultrasonography. The radiographs were graded using the Kellgren-Lawrence (KL) Scale. The association between meniscal extrusion and severity of knee osteoarthritis were analyzed. Results Medial meniscal protrusion was detected with high frequency ultrasonography in 52 of 71 knees with osteoarthritis, with mild protrusion in 17 knees, moderate extrusion in 24 knees and severe extrusion in 11 knees. All of the 71 knees with osteoarthritis were abnormal on X-ray films. KL Scale was 1 in 12 knees, 2 in 26 knees, 3 in 21 knees and 4 in 12 knees. Mild medial meniscal extrusion was found in 3 knees in controls, of which KL was 1 in 2 knees. X-ray films of 13 knees in controls were normal. Patients with osteoarthritis had more medial meniscal extrusion than controls (χ2=15.23, P＜0.001). The severe degree of meniscal extrusion was correlated with KL score (χ2=27.01, P＜0.001). Conclusion Medial meniscal extrusion is a prominent feature on knee ultrasonography imaging in patients with osteoarthritis and is associated with appearance of radiographic signs of osteoarthritis. |
