Study: Obesity Associated with Infection after Surgery for Acetabulum and Pelvis Fracture

Obesity increases risk of infection after surgery for acetabulum or pelvis fractures, according to a systematic review published in the April issue of the Journal of the AAOS: Global Research & Reviews ®. Fifteen studies through 2020 were included. Eight studies found that increased BMI was a risk factor for infection or wound complications. Two studies found obesity was significantly associated with reduction loss. Obesity was not clearly associated with the occurrence of other reported complications, including revision, venous thromboembolism, nerve palsy, heterotopic ossification, or general systemic complications.

Study: Re-tear Rate after Suture Bridge Versus Tripe-row Techniques in Arthroscopic RCR

A retrospective study published online in Arthroscopy compared re-tear rates after arthroscopic rotator cuff repair (RCR) using the knotless suture bridge (SB) or triple-row (TR) technique. SB and TR techniques were used in 212 and 206 shoulders, respectively. All patients underwent MRI after six months and functional testing preoperatively and at two years postoperatively. There was a significantly higher incidence of Sugaya classification type 5 re-tear in SB-treated shoulders (9.4 percent) compared to TR-treated shoulders (3.9 percent). Both groups achieved significant improvement in functional scores and had similar clinical outcomes at final follow-up.

Study: Engagement with Patient Education App among Patients Receiving TJA

A study published online in The Journal of Arthroplasty measured trends in patient engagement with application-based education technology used perioperatively following total joint arthroplasty (TJA). Between 2017 and 2018, 207 patients undergoing TJA were invited to use the patient education software, which included modules delivered at set intervals during the perioperative period. Overall, 54 percent of invited patients completed registration, and 48 percent completed around half of the modules. Physical therapy and exercise videos, health literacy, and anxiety, stress, and pain management resources were the most popular categories. Nutrition planning and education were the least viewed categories.

Study: Complications after All Pedicle Screw PSF for Adolescent Scoliosis

A retrospective study published online in BMC Musculoskeletal Disorders evaluated single-staged posterior spinal fusion (PSF) using an only pedicle screw system for treating adolescent idiopathic scoliosis. Overall, 1,057 patients (mean age = 15.6 years) treated between 2012 and 2019 were included. Lenke 1 was the most common curve type (46.9 percent). Mean operative time was 146.8 minutes and mean intraoperative blood loss was 952.9 ml. Five percent of patients required transfusion. The rate of major and minor complications were 0.95 percent and 1.32 percent, respectively. Infection was the most common complication (1.32 percent) and neurologic complications occurred in 0.47 percent of patients.

Lin Han, PhD, Receives Kappa Delta Young Investigator Award

This year, Lin Han, PhD, received the Kappa Delta Young Investigator Award for his role in furthering the understanding of cartilage regeneration and disease intervention in osteoarthritis (OA). Utilizing nanomechanical tools, Dr. Han and colleagues discovered new molecular activities that govern the proper functioning of healthy cartilage extracellular matrix (ECM) and the degeneration of ECM in OA. It was the first work to study the nanoscale dynamic mechanical behaviors of cartilage.

Orthopaedic and Podiatric Surgeons Joint Task Force Announce Consensus Statements

Editor’s note: The following brief was originally published in Headline News Now last Friday but it included incorrect links for additional information The correct link is listed below. We apologize for the error.

Since 2018, the Joint Task Force of Orthopaedic and Podiatric Surgeons has worked on mutually beneficial policy goals. The four participating organizations are the American Academy of Orthopaedic Surgeons (AAOS), the American College of Foot and Ankle Surgeons (ACFAS), the American Orthopaedic Foot and Ankle Society (AOFAS), and the American Podiatric Medical Association (APMA). Now after years of thoughtful discussion and deliberation, the task force has unanimously endorsed a white paper, which addresses the goal of equivalency in education pathways and certification. The next step in this process is a resolution that was recently submitted for consideration at the June 2021 Special Meeting of the American Medical Association House of Delegates. Both the white paper and resolution demonstrate the goal shared by orthopaedists and podiatrists in standardizing education and accreditation for care of the foot, ankle, and lower leg. The Task Force is proud of its combined efforts to date and looks forward to continued valuable collaboration between the professions to benefit its members and patients in the future.
