Painful total knee arthroplasty (TKA) represents a diagnostic challenge for the clinician and radiologist, as there is a wide variety of potential etiologies, with a broad range of clinical presentations, and the abnormalities on imaging studies are often subtle, absent, or nonspecific. Imaging findings of normal TKA are reviewed, in addition to a variety of complications such as loosening, infection, instability, osteolysis, heterotopic ossification, extensor mechanism disruption, and fracture. Although imaging evaluation of painful TKA is usually limited to conventional radiographs and nuclear imaging, examples of the utility of computed tomography are also illustrated, and suggested imaging strategies and algorithms are discussed.
疼痛性全膝关节置换术（TKA）对临床医生和放射科医生来说是一项诊断挑战，因为其潜在病因多种多样，临床表现范围广泛，而且影像学检查的异常往往很细微、不存在或不具特异性。除了诸如松动、感染、不稳定、骨溶解、异位骨化、伸肌机制破坏和骨折等各种并发症外，还回顾了正常TKA的影像学表现。尽管对疼痛性TKA的影像学评估通常仅限于传统X线片和核成像，但也展示了计算机断层扫描的应用实例，并讨论了建议的影像学策略和算法。
