The purpose of this study was to assess the effectiveness of the ultrasonography (US) on detecting osteoarthritis of the knee, and compare US and radiographic findings to intraoperative total knee arthroplasty (TKA) findings. Fifty-seven late-stage osteoarthritic knees undergoing TKA were evaluated with US and radiography. Standard knee US assessing femoral cartilage damage, osteophytes, effusion, synovitis, and meniscal extrusion was performed. On radiographs, osteophytes, joint space narrowing, and Kellgren-Lawrence grade were evaluated. Corresponding intra-operative findings were assessed during TKA as the gold standard. On the damage of the medial femoral condyle cartilage, the sensitivity of US was high (92%), whereas on the lateral condyle and sulcus area, sensitivities were 58% and 46%, respectively. On osteophytes, the detection rate of the US was remarkable especially on the medial side yielding sensitivities of 90-95%. The sensitivities for detecting effusion and synovitis were also excellent (97%). US detection rate of femoral cartilage damage was in concordance with the radiographic joint space narrowing. For the detection of osteophytes, US provided superior results to radiography particularly on the medial side. In conclusion, US can reliably assess the late-stage OA changes of the knee especially on the medial side of the knee joint.

全膝关节置换术前晚期膝关节骨关节炎的超声检查：超声检查，影像学检查和术中检查结果的比较。

这项研究的目的是评估超声检查（US）在检测膝盖骨关节炎中的有效性，并将超声检查和X线照片与术中全膝关节置换术（TKA）进行比较。通过US和X光检查评估了57例接受TKA的晚期骨关节炎膝盖。进行标准膝关节US评估股骨软骨损伤，骨赘，积液，滑膜炎和半月板挤压。在X光片上，评估骨赘，关节间隙变窄和Kellgren-Lawrence等级。在TKA期间将相应的术中发现评估为金标准。在股内侧con软骨损伤方面，US的敏感性较高（92％），而在外侧con和沟区域的敏感性分别为58％和46％。在骨赘上 美国的检出率显着，尤其是在内侧，检出灵敏度为90-95％。检测积液和滑膜炎的敏感性也极好（97％）。在美国，股骨软骨损伤的检出率与影像学的关节间隙变窄相一致。对于骨赘的检测，US提供了比射线照相更好的结果，尤其是在内侧。总之，US可以可靠地评估膝盖的晚期OA变化，尤其是在膝关节的内侧。US提供了比X射线摄影更好的结果，尤其是在内侧。总之，US可以可靠地评估膝盖的晚期OA变化，尤其是在膝关节的内侧。US提供了比X射线摄影更好的结果，尤其是在内侧。总之，US可以可靠地评估膝盖的晚期OA变化，尤其是在膝关节的内侧。
