Fluoroscopy Knee There is insufficient evidence to support the use of fluoroscopy for the initial evaluation of TKA. Image-Guided Aspiration Knee There is insufficient evidence to support the use of image-guided aspiration for the initial evaluation of TKA. MRI Knee Without and With IV Contrast There is insufficient evidence to support the use of MRI without and with IV contrast for the initial evaluation of TKA. MRI Knee Without IV Contrast There is insufficient evidence to support the use of MRI without IV contrast for the initial evaluation of TKA. Radiography Knee Radiographs can demonstrate abnormal bone and hardware alignment, periprosthetic lucencies and osteolysis [18- 24], reactive bone formation and periostitis, periprosthetic fractures, evidence of polyethylene liner wear, and cement and heterotopic bone about the knee. Radiographs can often delineate effusion, soft-tissue swelling, foreign bodies, soft tissue emphysema, heterotopic bone, and cement or metal in the soft tissues. Radiographs are useful as the initial evaluation for symptomatology or follow-up. Radiographs are often limited in terms of sensitivity, and further imaging may be required. Imaging After Total Knee Arthroplasty Routine immediate postoperative radiographs are considered unnecessary unless the surgery is complicated or there are specific clinical indications warranting imaging evaluation [25,26], because several studies have indicated that the rate of complications identified in the immediate postoperative setting is low. Ververeli et al [27] compared recovery room radiographs with additional predischarge radiographs and found no change in the postoperative management of 124 consecutive patients with TKAs and suggested eliminating the predischarge radiographs.
