Total knee arthroplasty (TKA) is the most commonly performed joint replacement procedure in the United States and annual demand for primary TKA is expected to grow by 673% by 2030. The first part provides an overview of imaging modalities (radiographs, CT, MRI, ultrasound, and various nuclear medicine studies) and discusses their usefulness in the imaging evaluation of TKA. The second part focuses on evidence-based imaging and imaging-guided intervention algorithms for the workup of TKA and its complications, including routine follow-up, component wear, periprosthetic infection, aseptic loosening, granulomas/osteolysis, conventional and rotational instability, periprosthetic fracture, patellar complications, and a variety of periprosthetic soft tissue abnormalities. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

... official IOC clinic within the Olympic Village, using digital ultrasound machines and 3T and 1.5T MR scanners. Image interpretation was performed centrally by board-certified musculoskeletal radiologists with expertise in sports injuries AbstractText: In total, 11 274 athletes (5089 women (45%), 6185 men (55%)) from 207 NOCs were included. NOC and Rio de Janeiro 2016 medical staff reported 1101 injuries.

OBJECTIVE: Electron beam therapy is a definitive radiation treatment option for superficial fibromatoses of the hands and feet. Because objective criteria for treatment response remain poorly defined, we sought to describe changes in electron beam treated lesions on MRI. MATERIALS AND METHODS: The study included 1 male and 9 female patients with a total of 37 superficial fibromatoses; average age was 60.7 years. Standard 6 MeV electron beam treatment included 3 Gy per fraction for 10 or 12 treatments using split-course with 3-month halfway break. Pre- and post-treatment MRIs were evaluated to determine lesion size (cm3), T2 signal intensity and contrast enhancement (5-point ordinal scales) by a fellowship trained musculoskeletal radiologist. MRI findings were correlated with clinical response using a composite 1-5 ordinal scale, Karnofsky Performance Scale and patient-reported 10-point visual analog scale for pain. RESULTS: Mean volume decreased from 1.5 to 1.2 cm(3) (p = 0.01, paired t-test). Mean T2 hyperintensity score decreased from 3.0 to 2.1 (p < 0.0001, Wilcoxon signed-rank). Mean enhancement score available for 22 lesions decreased from 3.8 to 3.0 (p < 0.0001, Wilcoxon signed-rank). Performance scores improved from 78.9 ± 13.7 to 84.6 ± 6.9 (p = 0.007, paired t-test). Pain scores decreased from 3.0 ± 3.3 to 1.1 ± 2.0 (p = 0.0001, paired t-test). Post-treatment T2 signal correlated weakly with performance and pain (Spearman's ? = -0.37 and 0.16, respectively). CONCLUSIONS: MRI is valuable for evaluating patients undergoing electron beam therapy for superficial fibromatoses: higher pretreatment T2 intensity may predict benefit from radiotherapy. T2 hypointensity may be a better marker than size for therapeutic effect.

Imaging was performed through the official IOC clinic within the Olympic Village, using digital X-ray cameras and 3T and 1.5T magnetic resonance (MR) scanners. Images were read centrally and retrospectively by musculoskeletal radiologists with expertise in sports injuries AbstractText: 11 274 athletes (5089 women (45%), 6185 men (55%)) from 207 NOCs participated in the study. 1101 injuries were reported.

AIMS: The aim of this paper was to present the clinical features of patients with musculoskeletal sources of methicillin-sensitive Staphylococcus aureus (MSSA) septicaemia. PATIENTS AND METHODS: A total of 137 patients presented with MSSA septicaemia between 2012 and 2015. The primary source of infection was musculoskeletal in 48 patients (35%). Musculoskeletal infection was considered the primary source of septicaemia when endocarditis and other obvious sources were excluded. All patients with an arthroplasty at the time were evaluated for any prosthetic involvement. RESULTS: The most common site of infection was the spine, which occurred in 28 patients (58%), and was associated with abscess formation in 16. Back pain was the presenting symptom in these patients, with a positive predictive value of 100%. A total of 24 patients had a total of 42 arthroplasties of the hip or knee in situ. Prosthetic joint infection occurred in six of these patients (25%). In five patients, the infection originated outside the musculoskeletal system. Three patients (6%) with MSSA septicaemia from a musculoskeletal sources died. CONCLUSION: Amongst the musculoskeletal sources of MSSA septicaemia, the spine was the most commonly involved. We recommend an MRI scan of the whole spine and pelvis in patients with MSSA septicaemia with back pain, when the primary source of infection has not been identified or clinical examination is unreliable.

Images were then retrospectively reviewed by a Consultant Musculoskeletal Radiologist and Musculoskeletal Radiologist Trainee to assess for the presence of concomitant hook of hamate fracture and, if present, whether this was identified on initial reporting AbstractText: Concomitant hook of hamate fracture was identified in 10.3% of cases (32 out of ...
... images of 40 patients' hamstrings with FAI and 45 age-matched controls. Images were identified and reviewed by 2 musculoskeletal radiologists for various signs of hamstring tendon pathology. Fisher's exact test and an odds ratio were used to assess for a difference in the occurrence of hamstring tendon pathology in the FAI patient cohort compared with the age-matched controls.
