Higher Patient Expectations Predict Higher Patient-Reported Outcomes, But Not Satisfaction, in Total Knee Arthroplasty Patients: A Prospective Multicenter Study.
The relationship between patient expectations, patient-reported outcomes (PROs), and satisfaction in total knee arthroplasty (TKA) patients is not well understood. ⋯ In TKA patients, preoperative expectations are not influenced by patient demographics or preoperative function. Higher preoperative expectations predict greater postoperative improvement in PROs and fulfillment of expectations. These findings highlight the importance of preoperative patient expectations on postoperative outcome.

The study's purpose was to determine if there is an association between ABO blood group and the development of symptomatic venous thromboembolism (VTE) after total joint arthroplasty (TJA). ⋯ AB blood group increased the risk of VTE after TJA. Patient's ABO blood group should be considered in terms of risk stratification and selection of appropriate postoperative VTE prophylaxis.

In an effort to improve quality and reduce costs, payments are being increasingly tied to value through alternative payment models, such as episode-based payments. The objective of this study was to better understand the pattern and variation in outcomes among Medicare beneficiaries receiving lower extremity joint arthroplasty over 90-day episodes of care. ⋯ Outcomes in our national cohort of Medicare beneficiaries receiving lower extremity joint arthroplasties varied across procedure types and patient characteristics. Future research examining trends in access to care, resource use, and care quality over bundled episodes will be important for addressing the challenges of value-based payment reform.

Gross trunnion failure (GTF) is a rare complication in total hip arthroplasty (THA) reported across a range of manufacturers. Specific lots of the Stryker low friction ion treatment (LFIT) anatomic cobalt chromium alloy (CoCr) V40 femoral head were recalled in August 2016. In part, the recall was based out of concerns for disassociation of the femoral head from the stem and GTF. ⋯ In our series of the recalled LFIT CoCr femoral head, the risk of impending GTF or head-neck taper corrosion should be considered as a potential diagnosis in a painful LFIT femoral head and Accolade titanium-molybdenum-zirconium-iron alloy THA with unknown etiology. Almost half of the failures we observed included sizes outside of the voluntary recall.

Total joint arthroplasty is one of the most common surgical procedures performed for end-stage osteoarthritis. The increasing demand for knee and hip arthroplasties along with the improvement in life expectancy has created a substantial medical and economic impact on the society. ⋯ The best method for providing anesthesia and analgesia for total joint arthroplasty has not been defined. Yet, emerging evidence suggests that the type of anesthesia can affect morbidity and mortality of patients undergoing these procedures.
