Central sensitization (CS) has been recently identified as a significant risk factor for persistent pain and patient dissatisfaction following total knee arthroplasty (TKA). However, it remains unclear as to whether the preoperative CS persists after the elimination of a nociceptive pain source by TKA, or how CS affects the quality of life after TKA. ⋯ Preoperative CS was persistent at 2 years after TKA. Although CS patients achieved comparable clinical improvement following TKA, CS patients had worse quality of life, functional disability, and dissatisfaction than non-CS patients.

Periarticular knee fractures present a significant challenge to minimize post-traumatic osteoarthritis. The purpose of this study is to compare the rates of conversion to total knee arthroplasty (TKA) for different periarticular knee fractures, investigate the rate of knee injections as a more rapid assessment of knee symptoms, and identify risk factors that lead to conversion to TKA following periarticular fractures. ⋯ Therapeutic Level III.

Care for patients during COVID-19 poses challenges that require the protection of staff with recommendations that health care workers wear at minimum, an N95 mask or equivalent while performing an aerosol-generating procedure with a face shield. The United States faces shortages of personal protective equipment (PPE), and surgeons who use loupes and headlights have difficulty using these in conjunction with face shields. ⋯ As a result, the authors have begun retrofitting these arthroplasty helmets to serve as PPE. The purpose of this article is to outline the conception, design, donning technique, and safety testing of these arthroplasty helmets being repurposed as PPE.

Outcomes following 1-surgeon single-anesthetic sequential bilateral total knee arthroplasty (seq-BTKA) compared to 2-surgeon single-anesthetic simultaneous bilateral total knee arthroplasty (sim-BTKA) are largely unknown. The current study compared revision rates and all-cause mortality following seq-BTKA vs sim-BTKA using data from the Australian Orthopedic Association National Joint Replacement Registry. ⋯ Revision rates and mortality were similar for seq-BTKA and sim-BTKA. Investigation of additional outcomes such as complications not requiring revision, pain, function, and cost is required to comprehensively understand the relative merits of each procedure.

The economic effects of the COVID-19 crisis are not like anything the U.S. health care system has ever experienced. ⋯ Our goal should be using these lessons to achieve a healthy and successful 2021 fiscal year.
