Context:Total joint arthroplasty (TJA) is a common surgical option to treat painful degenerative joint disease. However, there is currently no consensus on the appropriate intensity of physical activity after TJA or how physical activity level affects the rate of revision surgery.Materials and Methods:A systematic review of the literature regarding physical or athletic activity after TJA was performed to determine current clinical opinion and recommendations regarding appropriate activity levels after TJA, as well as variables affecting successful surgery and improved outcomes.Results:Many studies in the literature regarding athletic activity after TJA focus on total hip arthroplasty and total knee arthroplasty. The literature reports contradictory results regarding rates of physical activity after TJA as well as the relationship between physical activity and rates of revision surgery. The current trend in expert opinion shows more liberal recommendations for patients to engage in athletic activity after TJA.Conclusions:Individual characteristics, lifestyle, and patient preferences must be taken into account when one considers appropriate recommendations for athletic activity after TJA. Current trends in clinical opinion favor a higher level of athletic activity after TJA, but clinicians should caution patients not to participate in contact sports or sports that create high joint loads in the replaced joint.

Purpose To identify factors important to patients for their return to elective imaging during the coronavirus disease 2019 (COVID-19) pandemic. Methods In all, 249 patients had elective MRIs postponed from March 23, 2020, to April 24, 2020, due to the COVID-19 pandemic. Of these patients, 99 completed a 22-question survey about living arrangement and health care follow-up, effect of imaging postponement, safety of imaging, and factors important for elective imaging. Mann-Whitney U , Fisher’s exact, χ 2 tests, and logistic regression analyses were performed. Statistical significance was set to P ≤ .05 with Bonferroni correction applied. Results Overall, 68% of patients felt imaging postponement had no impact or a small impact on health, 68% felt it was fairly or extremely safe to obtain imaging, and 53% thought there was no difference in safety between hospital-based and outpatient locations. Patients who already had imaging performed or rescheduled were more likely to feel it was safe to get an MRI (odds ratio [OR] 3.267, P = .028) and that the hospital setting was safe (OR 3.976, P = .004). Staff friendliness was the most important factor related to an imaging center visit (95% fairly or extremely important). Use of masks by staff was the top infection prevention measure (94% fairly or extremely important). Likelihood of rescheduling imaging decreased if a short waiting time was important (OR = 0.107, P = .030). Conclusion As patients begin to feel that it is safe to obtain imaging examinations during the COVID-19 pandemic, many factors important to their imaging experience can be considered by radiology practices when developing new strategies to conduct elective imaging.
