006) and stage 2 (6.3 vs 3.6 days, P < .001). Although it did not reach statistical significance with the numbers available for study, nearly twice as many patients in the static cohort were discharged to an extended care facility after stage 1 (65% vs 30%, P= .056).

This randomized trial demonstrated that the outcomes of static and articulating spacers are similar in the treatment of THA PJI undergoing 2-stage exchange arthroplasty. The significantly longer length of hospital stay associated with the use of static spacers may have important economic implications for the health care system.

Approximately 20% of patients are dissatisfied with their total knee arthroplasty (TKA) at 1-year post-surgery. Met expectations have been found by some to significantly predict satisfaction. The role of met expectations in determining patient satisfaction has not been exhaustively explored. PI3K inhibitor The primary aim of this study is to evaluate if met expectations moderate the relationship between pain and function variables and satisfaction.

Patients who underwent primary TKA for osteoarthritis were included in the study (n= 304). Patient-reported outcomes at pre-surgery and 1-year post-surgery were collected. The Knee Society Score (KSS) satisfaction subscale was used as the dependent variable. Candidate independent variables included the following demographics, KSS, Knee injury and Osteoarthritis Outcome Score (KOOS), 12-Item Short Form Health Survey (SF-12), Hospital Anxiety and Depression Scale, Pain Catastrophizing Scale, Self-Administered Comorbidity Questionnaire, and University of California Los Angeles activity score. Separate linear regression models were created to test interactions for KSS met expectations with pain and KSS met expectations with function.

Significant predictors of satisfaction were KSS symptoms (pain), KOOS activities of daily living (function), KSS met expectations, KOOS pre-surgery activities of daily living, body mass index, and SF-12 general health. A significant interaction between met expectations and pain was found (P= .043) and the met expectations and function interaction approached significance (P= .086). For both interactions, as met expectations increased, pain and function predicted satisfaction less strongly.

Met expectations were found to moderate the relationship between pain and satisfaction. There may be more value in improving pain for patients with low met expectations.

The COVID-19 pandemic caused an abrupt disruption in residency and fellowship training, with most in-person teaching ceasing in March 2020. The AAHKS (American Association of Hip and Knee Surgeons) Board of Directors quickly initiated an online lecture series named the Fellows Online COVID-19 AAHKS Learning initiative. The purpose of this study is to illustrate the impact that this educational platform had on residents and adult hip and knee reconstruction fellows.

Between March 31, 2020 and June 25, 2020 an online educational platform was simultaneously developed and delivered. Adult hip and knee reconstruction fellows and residents were invited to participate in the free, live, online education sessions. Faculty from well-respected institutions from around the United States volunteered their time to host the initiative, choosing topics to present, ranging from hip (13 lectures) and knee (9 lectures), to practice management/miscellaneous (12 lectures). Attendee registrations were tracked via the online prldwide lectures may lead to future opportunities in virtual residency and fellowship education.
Amid a pandemic with cessation of in-person training, AAHKS delivered a robust virtual training alternative, exposing residents and fellows to a variety of renowned faculty and topics. Attendance with the program was very high, along with continued interest to continue this initiative. These worldwide lectures may lead to future opportunities in virtual residency and fellowship education.
The purpose of this study was to investigate whether patient-reported knee function and health status before and after primary total knee replacement (TKR) at an academic medical center differs among patients from diverse geographic regions.

We assessed patient-reported outcomes (PROs) as measured by the Oxford Knee Score (OKS) and EuroQoL-5D (EQ-5D) in 2855 TKR patients at preprimary and one year postprimary TKR procedure between January 1, 2012 and June 30, 2014. We compared the demographic characteristics, response rates, and changes in OKS, EQ-5D, and EQ visual analog scale among local, regional, and national patient groups. Patient- or hospital-related predictors of the postoperative scores were identified after controlling for preoperative scores on the PRO measures.

Local patients had more comorbid conditions. Groups were similar in clinical outcomes such as length of stay at hospital, complication, and reoperation rates. Local, regional, and national patients had similar response rates and reported a similar level of knee function and health-related quality of life before and after TKR. Eighty nine percent had clinically important improvement on OKS, 69% on EQ-5D index, and 28% EQ visual analog scale, and there were no differences among groups in the proportions of clinically meaningful change. Better postoperative PRO scores were associated with older age, shorter hospital stay, fewer comorbidities, nonsmoking status, fewer complications, and private health insurance.

Some patient characteristics such as comorbidities were greater in the local patient cohort versus the national cohort. Nevertheless, clinical outcomes and PROs were comparable across all geographic tiers.
