Obesity is frequently associated with complications after total hip arthroplasty (THA) and is often concomitant with malnutrition. The purpose of this study was to investigate the independent morbidity risk of malnutrition relative to obesity. ⋯ Malnutrition incidence increased significantly from obese I to obese III patients and was a stronger and more consistent predictor than obesity of complications after THA.

Inferior outcomes for medial unicompartmental knee arthroplasty (UKA) patients with preoperative medial tibial bone marrow lesions (BMLs) were recently reported. The purpose of this study was to compare the location and severity of BML on postoperative outcomes after medial UKA and TKA using a larger sample size and more rigorous magnetic resonance imaging (MRI) evaluation. ⋯ Medial tibial BMLs were not associated with inferior outcomes. Clinically, these results suggest that BMLs should not be considered a contraindication for medial UKA.

Centers for Medicare and Medicaid Services are now using results from patient satisfaction surveys, such as Press Ganey, for reimbursement. It is unknown what factors influence scores on satisfaction surveys in post-total hip arthroplasty (THA) patients. The purpose of this study was to evaluate what influences these scores in THA patients. Specifically, we aimed to evaluate: (1) how pain control affects the patients' perception of their orthopedist, nursing staff, and overall hospital satisfaction; (2) the individual impact of these factors on overall hospital satisfaction after THA; and (3) the impact of lengths of stay, age, body mass index (BMI), and American Society of Anesthesiology (ASA) scores on overall satisfaction. ⋯ Post-THA patients associate pain management with hospital satisfaction, as well as their perception of their treating nurses and orthopedists. Overall satisfaction was most impacted by patients' perception of their nurse, followed by their orthopedist. In addition, there was an association between shorter length of stay and higher overall satisfaction. These results are of paramount importance because by recognizing factors that affect scores on satisfaction surveys, orthopedic surgeons can direct efforts to improve post-THA satisfaction and optimize reimbursements.

Cirrhosis is a major cause of morbidity and mortality and is an important risk factor for complications in surgical patients. The purpose of this study was to investigate the association of cirrhosis with postoperative complications, length of stay (LOS), and costs among patients who underwent total knee arthroplasty (TKA) or total hip arthroplasty (THA). ⋯ Patients with cirrhosis who are undergoing TKA or THA are at a significantly increased risk for perioperative complications, increased LOS, and higher costs. The perioperative complications and costs were highest among patients with alcohol-related cirrhosis.

Review Meta Analysis
Aspirin as Thromboprophylaxis in Hip and Knee Arthroplasty: A Systematic Review and Meta-Analysis.
Venous thromboembolism (VTE) comprises pulmonary embolism and deep vein thrombosis and is a complication of particular concern in lower limb arthroplasty. In recent years, aspirin has emerged as a potential alternative thromboprophylactic agent, particularly after its acceptance as a recommended agent by the American College of Chest Physicians. Aspirin is favorable due to its relative cost-effectiveness and convenience compared to novel oral anticoagulants and warfarin. However, its efficacy since its inclusion in the American College of Chest Physicians guidelines remains unclear. The present systematic review aimed to establish the efficacy of aspirin in preventing VTE in total hip and knee arthroplasty. ⋯ Aspirin, both alone and in multimodal approaches to thromboprophylaxis, confers a low rate of VTE, with a low risk of major bleeding complications. However, the evidence for its use is limited by the low quality of studies and variation in dose in dosing regimes. Future randomized controlled trials should investigate the efficacy of aspirin, as well as the ideal dosing protocol for its use in thromboprophylaxis in arthroplasty.
