Preoperative hyponatremia is an independent risk factor for postoperative complications in aseptic revision hip and knee arthroplasty.

J Orthop

January 2020

Adult Reconstruction and Joint Replacement Division, Department of Orthopaedic Surgery, Hospital for Special Surgery, 535 E 70th, St, New York, NY, 10021, USA.

Introduction: The purpose of this study is to investigate the relationship between preoperative hyponatremia and postoperative complications in aseptic revision hip and knee arthroplasty.

Methods: Aseptic revision arthroplasties from 2007 to 2016 were collected using a large, United States database. Patients were stratified into eunatremic and hyponatremic cohorts.

Introduction: The objective of this study was to determine whether chronic preoperative corticosteroid use is associated with increased infectious complications following revision total knee arthroplasty (rTKA).

Methods: A retrospective cohort analysis was conducted using patients from a large national database. Patients were divided into two cohorts based upon chronic steroid usage preoperatively.

Patient expectations have been shown to be an independent predictor of outcomes in clinical medicine. In the orthopaedic literature, the majority of studies have focused on the relationship between pre-operative expectations and post-operative outcomes in patients undergoing total hip arthroplasty, total knee arthroplasty, shoulder surgery, and spine surgery. Various methodologies have been used to assess patient expectations in orthopaedic surgery, including direct questioning, short questionnaires, and validated surveys.

Aims: Few studies have evaluated the relationship between patients' pre-operative expectations and the outcome of orthopaedic procedures. Our aim was to determine the effect of expectations on the outcome after primary anatomical total shoulder arthroplasty (TSA). We hypothesised that patients with greater expectations would have better outcomes.

Osteochondral Autograft Transplantation Surgery for Metacarpal Head Defects.

J Hand Surg Am

March 2016

Department of Orthopaedic Surgery, Boston Children's Hospital, Boston, MA. Electronic address:

Post-traumatic osteonecrosis of the metacarpal head is a challenging problem, particularly in younger patients in whom arthroplasty may not be a durable option. Although several osteochondral reconstructive options have been proposed, some are associated with considerable donor site morbidity and/or require the use of internal fixation. We present an application of osteochondral autograft transplantation surgery as a treatment option for focal metacarpal head lesions.

Placement of an Intramedullary Nail for the Treatment of Proximal Ulnar Fractures.

JBJS Essent Surg Tech

December 2015

MedStar Georgetown Orthopaedic Institute, MedStar Washington Hospital Center, Physicians Office Building, Suite 5000, 106 Irving Street N.W., Washington, DC 20010.

Introduction: The fixation of olecranon fractures with intramedullary olecranon nails has been demonstrated to be an effective treatment option that may result in decreased soft-tissue irritation.

Step 1 Positioning And Approach: Proper positioning of the patient during this procedure allows for improved access to the fracture and increased accessibility for fluoroscopy.

Step 2 Reduce The Fracture: Reduce and provisionally hold the fracture following a limited periosteal elevation.

Ankle arthroscopy for ankle fractures.

Arthrosc Tech

February 2015

Orthopaedic Surgery Department, MedStar Georgetown University Hospital, Washington, DC, U.S.A. ; MedStar Georgetown Orthopaedic Institute, Washington, DC, U.S.A.

In many patients who undergo open reduction-internal fixation of ankle fractures, there is a failure to achieve good clinical outcomes despite radiographic evidence of anatomic reduction. One possible reason for this is the high incidence of concomitant intra-articular pathology associated with ankle fractures that may go unrecognized using traditional open approaches. Arthroscopy in the setting of acute operative management of ankle fractures provides a means to completely assess intra-articular pathology, as well as provide direct therapeutic intervention in many instances.

Patients with mixed-type femoroacetabular impingement syndrome often have concomitant chondrolabral pathology in addition to the characteristic cam and pincer lesions. Unfortunately, these patients are typically young, and the pathology is localized to the weight-bearing dome of the acetabulum. Complete preoperative characterization of labral and cartilage lesions is often not possible even with advanced imaging techniques, and the full extent of the injury may not be appreciated without direct arthroscopic visualization.

Does the use of ultrasound affect contamination of musculoskeletal injections sites?

Clin Orthop Relat Res

January 2015

MedStar Georgetown Orthopaedic Institute, Georgetown University Hospital, 3800 Reservoir Road, PHC Floor 1, Washington, DC, 20007, USA,

Background: Therapeutic musculoskeletal injections require a clean or sterile skin preparation to minimize the risk of infections. Ultrasound guidance for this procedure requires the use of transmission gel in proximity to the injection site, and its effect on maintaining sterility is unknown.

Questions/purposes: We asked: (1) Does sterile ultrasound transmission gel increase skin contamination during therapeutic orthopaedic injections? (2) Does nonsterile gel application result in increased contamination? (3) Does a manufacturer-approved ultrasound probe disinfecting agent in the form of 17.

Background: Most synovial sarcomas contain a chromosomal translocation t(X;18), which results in the formation of an oncoprotein SS18-SSX critical to the viability of synovial sarcoma.

Questions/purposes: We (1) established and characterized three novel synovial sarcoma cell lines and asked (2) whether inhibition of SS18-SSX1 decreases cell viability in these cell lines; and (3) whether reduction in viability after SS18-SSX1 knockdown is caused by apoptosis. After identifying a specific posttranscriptional splice variant in our cell lines, we asked (4) whether this provides a survival benefit in synovial sarcoma.
