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.

Residual Symptoms and Function After Unicompartmental and Total Knee Arthroplasty: Comparable to Normative Controls?
Whether patient-reported symptoms and function after total knee arthroplasty (TKA) and medial unicompartmental knee arthroplasty (UKA) compare favorably to similar individuals without a diagnosis of knee pathology has not been investigated. ⋯ When interviewed by an independent, third party, a substantial percentage of control patients reported the presence of knee symptoms, but to a lesser degree than patients after a knee arthroplasty.

Topical vs Intravenous Tranexamic Acid in Primary Total Hip Arthroplasty: A Double-Blind, Randomized Controlled Trial.
Tranexamic acid (TXA) reduces perioperative blood loss in total hip arthroplasty (THA). ⋯ IV and topical TXA are effective tools to reduce blood loss and transfusion costs in THA, and we recommend the IV form for ease of use.

Does Neuraxial Anesthesia Decrease Transfusion Rates Following Total Hip Arthroplasty?
Perioperative transfusions increase complications and cost following THA. Current series evaluating neuraxial anesthesia and blood loss following THA are small and utilize heterogeneous populations. Using the NSQIP database we compared transfusion rates following THA with neuraxial and general anesthesia. ⋯ Operative time and length of stay were shorter with neuraxial anesthesia as well. After adjusting for patient comorbidities, a multivariate regression model showed fewer transfusions with neuraxial anesthesia. The multivariate regression model showed additional independent risk factors for transfusion including gender, operative time, elevated INR, and a history of hypertension, metastatic cancer, and renal failure.

Multicenter Study
Knee pain during the first three months after unilateral total knee arthroplasty: a multi-centre prospective cohort study.
Many patients have an unfavourable pain outcome post total knee arthroplasty (TKA). This multi-centre prospective cohort study recorded weekly pain scores one week before TKA and 12 weeks post TKA. 96 patients were enrolled into the study. Patients kept a record of their weekly scores pre-operation and post-operation by using the visual acuity score. ⋯ Patients with a pre-operative pain scores ≤ 4 were identified as an at risk group for poor pain outcome. Female gender, age and anaesthetics type were not identified as risk factors for poor pain outcome. Pain trajectory analysis also identified general patterns of pain response post TKA.
