High Variability of Mesenchymal Stem Cells Obtained via Bone Marrow Aspirate Concentrate Compared With Traditional Bone Marrow Aspiration Technique.

Background: Bone marrow aspirate (BMA) is a common source for harvesting mesenchymal stem cells (MSCs), other progenitor cells, and associated cytokines and growth factors to be used in the biologic treatment of various orthopaedic pathologies. The aspirate is commonly centrifuged into a concentrated volume that can be immediately administered to a patient using commercially available kits. However, the handling and efficacy of BMA concentrate (BMAC) are still controversial.

Biomechanics of the Injured Fibula Following Plate Fixation of a Concomitant Tibia Fracture To Fix or Not to Fix?

Background: The mechanical role of supplemental fibula fixation in both bone lower leg fractures is not well defined. The benefit of fibula plate fixation in this context is controversial. The purpose of this study was to ascertain the mechanical contributions of the fibula under three conditions (intact, fractured, or plated fibula) following standard tibia locked plating.

Increased Survivorship of Cementless versus Cemented TKA in the Morbidly Obese. A Minimum 5-Year Follow-Up.

Background: Total knee arthroplasty (TKA) in the morbidly obese patients can be challenging with an increased risk of complications. Studies have shown increased aseptic failures with well-aligned cemented TKAs in the obese patient. The purpose of this study is to determine if TKA in the morbidly obese (body mass index [BMI] ≥ 40) using cementless implants would demonstrate improved results and survivorship compared to cemented TKA at a minimum 5-year follow-up.

Behavioral Economics and Physician Board Meetings: Opportunity Cost, Regret, and Their Mitigation in Orthopaedic Surgery.

Health care is a business. Health care providers must become familiar with terms such as opportunity costs, the potential loss or gain when one choice is made in lieu of another. The purpose of this study was to calculate the opportunity cost of two orthopaedic surgery society board meetings and discuss these in the context of behavioral economics and regret.

Outcomes after plating of olecranon fractures: A multicenter evaluation.

Introduction: The aim of this study was to report the physical and functional outcomes after open reduction internal fixation of the olecranon in a large series of patients with region specific plating across multiple centres.

Patients/methods: Between January 2007 and January 2014, 182 consecutive patients with a displaced olecranon fracture treated with open reduction internal fixation were included in this study. Retrospective review across four trauma centres collected elbow range of motion, DASH scores, hardware complications, and hardware removal.
