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.

Multiple Boluses of Intravenous Tranexamic Acid to Reduce Hidden Blood Loss After Primary Total Knee Arthroplasty Without Tourniquet: A Randomized Clinical Trial.
The optimal dosage and timing of tranexamic acid (TXA) in total knee arthroplasty (TKA) are undetermined. The purpose of this study was to explore the effect of multiple boluses of intravenous TXA on hidden blood loss (HBL), inflammatory response, and knee function after primary TKA without tourniquet. ⋯ Multiple boluses of IV-TXA can effectively reduce HBL after primary TKA without tourniquet. What is the most important is that, by adding another bolus of IV-TXA, patients can gain a smaller decline of Hb, less postoperative inflammatory response, less pain, less knee swelling, better knee function, and shorter LOH.

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.

Osteonecrosis of femoral head is a serious relentlessly progressive and disabling complication in 20%-50% of sickle cell patients, majority of whom are in their second to third decades. High perioperative medical complications and short survivorship have historically discouraged arthroplasty surgeons in offering total hip arthroplasty to sickle cell patients in their 30s for the fear of inevitable technically demanding revision. In this retrospective study, the primary objective was to assess the impact of early intervention on quality of life (QOL) at midterm follow-up of mean 7.5 years using uncemented porous-coated total hip arthroplasty. The secondary objective of this study was the survival of the prostheses within the same follow-up period and discussion of surgical challenges faced in this cohort of patients. ⋯ We recommend early hip arthroplasty in sickle cell patients, if the hip has reached a stage of irreversible damage and patient's lifestyle is severely compromised to minimize chronic suffering and disability.
