Do TKAs in Patients with Higher BMI Take Longer, and is the Difference Associated with Surgeon Volume? A Large-database Study from a National Arthroplasty Registry.

Background: Increased surgical time in TKA may impact economic costs and clinical outcomes. Prior work has found that TKAs in patients with high BMI take longer, and these patients may be at greater risk for postoperative complications like infection. However, these studies included small numbers of patients and surgeons from single institutions and they did not consider surgeon volume.

Comparable outcomes of in-cement revision and uncemented modular stem revision for Vancouver B2 periprosthetic femoral fracture at 5 years.

Introduction: Periprosthetic femoral fractures (PFF) are detrimental for patients. Vancouver B2 fractures about a cemented stem can be revised to a longer uncemented stem or using an in-cement revision, if the cement mantle is adequate. There are reports documenting the success of both techniques.

External validation study of hip peri-prosthetic joint infection with cemented custom-made articulating spacer (CUMARS).

Introduction: Peri-prosthetic joint infection (PJI) is a devastating complication after total hip arthroplasty (THA). The use of custom-made articulating spacers (CUMARS) has been described for use in the first of 2-stage treatment. We report our outcomes of managing PJI using CUMARS.

Results of hydroxyapatite ceramic coated primary femoral stem in revision total hip replacement.

Purpose: The purpose of this study was to assess survival rate, functional and radiological outcomes when using a hydroxyapatite-ceramic fully coated primary femoral stem in revision total hip arthroplasty.

Methods: Patients who underwent revision total hip arthroplasty using the Furlong hydroxyapatite-ceramic (HAC)-coated (Joint Replacement Instrumentation Ltd., Sheffield, UK) primary stem were retrospectively identified between 2013 and 2017.

Arthroscopic versus open ankle arthrodesis.

Background: It is thought that arthroscopic ankle fusion offers improved outcomes over open fusion in terms of functional outcomes, time to fusion, length of stay and fewer complications. However, there are doubts about whether correction of established severe deformity can be achieved using the arthroscopic approach.

Methods: A retrospective review of medical records and radiographs at our hospital identified consecutive tibio-talar ankle fusions between April 2009 and March 2014 with minimum 1 year follow up.

Starvation Resulting From Inadequate Dietary Planning for a 50-Day Rowing Expedition.

Unlabelled: Meeting the energy demands of prolonged arduous expeditions and endurance sport may be a significant barrier to success. Expedition rowing is associated with high levels of body-mass loss, reflecting the challenge of meeting energy expenditure in this exacting environment.

Purpose: To use the doubly labeled water (DLW) technique to calculate the total energy expenditure (TEE) and body-composition changes of two 28-y-old healthy male athletes during a 50-d continuous and unsupported row around Great Britain.

The effect of different methods of stability assessment on fixation rate and complications in supination external rotation (SER) 2/4 ankle fractures.

Background: Distinguishing stable supination-external rotation (SER) 2 from unstable SER 4 ankle fractures, using standard radiographs, is controversial. Examination under anaesthesia (EUA), gravity-stress (GS) and weight-bearing (WB) radiographs can aid surgical decision-making. We evaluated the effect of three methods of fracture stability assessment.

Is asymptomatic bacteriuria a risk factor for prosthetic joint infection?

Background: Infection is a major complication after total joint arthroplasty. The urinary tract is a possible source of surgical site contamination, but the role of asymptomatic bacteriuria (ASB) before elective surgery and the subsequent risk of infection is poorly understood.

Methods: Candidates for total hip or total knee arthroplasty were reviewed in a multicenter cohort study.

Artificial ligament reconstruction of sternoclavicular joint instability: report of a novel surgical technique with early results.

Symptomatic instability of the sternoclavicular (SC) joint is an uncommon problem. The majority of patients respond well to nonoperative measures, although a small number require reconstructive surgery for symptomatic instability, with varying surgical techniques reported in the literature. We report a series of 5 operations (in 4 patients) with chronic SC joint instability treated by reconstruction of SC and costoclavicular ligaments using an artificial ligament weave (LARS: Ligament Augmentation and Reconstruction System).
