Over One-Third of Patients with Multi-Ligament Knee Injuries and An Intact Anterior Cruciate Ligament Demonstrate Medial Meniscal Ramp Lesions on Magnetic Resonance Imaging
The objective of this study was to determine the incidence of ramp lesions and posteromedial tibial plateau (PMTP) bone bruising on magnetic resonance imaging (MRI) in patients with multiligament knee injuries (MLKIs) and an intact anterior cruciate ligament (ACL). Over one-third of MLKI patients with an intact ACL were diagnosed with medial meniscus ramp lesions (MMRLs) on MRI in this series. PMTP bone bruising was observed in 66.7% of patients with MMRLs, suggesting that increased vigilance for identifying MMRLs at the time of ligament reconstruction should be practiced in patients with this bone bruising pattern.
How to Use a Foam Roller In Your Workout Routine (and the Benefits of Foam Rolling)
Foam rollers can be used to apply targeted pressure to your muscles pre- or post-workout, and they can make a major difference in recovery and flexibility. Research also shows foam rollers can speed up recovery and enhance overall muscular performance.Source: Shape Magazine
Repair of Acute Grade 3 Combined Posterolateral Corner Avulsion Injuries Using an Enhanced Fixation Technique
Previous studies have suggested that surgical repair of the posterolateral corner (PLC) may be inferior to reconstruction. Researchers hypothesized that acute repair (<3 weeks) of avulsion-type PLC multiligament knee injuries with no midsubstance injury would lead to lower failure rates than previously reported for PLC repair.
Yale Veterans Coordinate Delivery of Orthopaedic Medical Supplies to Ukraine
Sometimes purpose, service, and responsibility converge to create new opportunities for meaningful action. For Adrian Bonenberger and his wife, Iryna Solomko, this included making another trip to Ukraine. Bonenberger is the editor of Yale Medicine Magazine and Solomko is a Ukrainian journalist who works for Voice of America. Their latest travel to Kyiv took place in October, shortly after the city had been struck by cruise missile and kamikaze drone attacks, and would serve myriad purposes.
AAA reports: Daylight saving time change makes roads more dangerous
Ahead of the clocks falling back an hour this weekend, experts say the time change from daylight saving makes the roads a more dangerous place to be. AAA reports that over the last five years, pedestrian-related crashes in the 5 p.m. hour shot up more than 200% during the month after the autumn time shift, compared to the month before. They also say for the same period, all crashes are up 56%.Source: News 12
10 Ways To Recover From a Marathon
Marathon runners know the importance of a solid training plan, one marked with a steady buildup in distance and key periods of rest that take them to their goal of covering 26.2 miles. But not all runners know how to properly recover from this event, which is so physically and mentally challenging. While there are countless 12- and 16-week marathon training plans that runners can find online, in books, or from a personal coach, it’s hard to locate the same level of detailed outline for what to do in the days and weeks after the big event.Source: Yale Medicine
UConn freshman Ice Brady’s dislocated patella: Experts explain injury, surgery, and recovery
On Wednesday, UConn women’s basketball program announced freshman Ice Brady will miss the 2022-23 season with a dislocated patella injury on her right knee. Brady, who was the No. 5 overall recruit in the Class of 2022, underwent surgery on Tuesday and began rehab on her knee Wednesday. UConn said Brady suffered the injury during practice on Oct. 21.Source: Connecticut Insider
Incidence, Timing, and Risk Factors for 5-Year Revision Surgery After Autologous Chondrocyte Implantation in 533 Patients
Autologous chondrocyte implantation (ACI) can be used to treat focal, full-thickness chondral defects of the knee. However, there is limited large-sample evidence available regarding the incidence, timing, and risk factors for revision surgery after ACI.
Ways to ease painful joints caused by osteoarthritis
As the years pass, many of us may begin to notice various aches and pains in our joints. One increasingly common cause of chronic discomfort is osteoarthritis, or OA, which is marked by a progressive loss of the cushioning material that keeps the ends of joints from rubbing together.Source: Washington Post
Three-dimensional printing versus freehand surgical techniques in the surgical management of adolescent idiopathic spinal deformity
Three-dimensional (3D) printed guides are finding increasing applications in the field of orthopaedic surgery and more recently spine surgery. This retrospective cohort study compares benefits and costs of 3D printed guides in surgical treatment of adolescent idiopathic scoliosis (AIS) compared to freehand techniques.
In-hospital complications after cervical fusion in cases with versus without cerebral palsy
Patients with cerebral palsy (CP) are at increased risk for cervical spine pathology. Cervical fusion surgery may be considered in this population, but perioperative outcomes relative to patients without CP remains poorly understood. The purpose of this study was to compare in-hospital complications after cervical fusion in patients with versus without cerebral palsy (CP) using a retrospective cohort design.
An open-access plug-in program for 3D modelling distinct material properties of cortical and trabecular bone
The authors demonstrate the development and use of a pre-processing plug-in program with a 3D modelling image processing software suite (Synopsys Simpleware, ScanIP) to assist with identifying, isolating, and defining cortical and trabecular bone material properties from patient specific computed tomography scans. The workflow starts by calibrating grayscale values of each constituent element with a phantom – a standardized object with defined densities. Using an established power law equation, we convert the apparent density value per voxel to a Young’s Modulus. The resulting “calibrated” scan can be used for modeling and in-silico experimentation with Finite Element Analysis.
Evaluating surface coatings to reduce bone cement adhesion to point of care 3D printed molds in the intraoperative setting
Polymethyl methacrylate, or “bone cement,” can be used intraoperatively to replace damaged or diseased bone and to deliver local antibiotics. 3D printed molds allow surgeons to form personalized and custom shapes with bone cement. One factor hindering the clinical utility of anatomically accurate 3D printed molds is that cured bone cement can be difficult to remove due to the strong adhesion between the mold and the bone cement. One way to reduce the adhesion between the 3D printed mold and the cured bone cement is with the use of a surface coating, such as a lubricant. This study sought to determine the optimal surface coating to prevent bone cement adhesion to 3D printed molds that could be utilized within a sterile operating room environment.
Adult Reconstruction Division Welcomes Ansab Khwaja, MD as 2022-23 Total Joint Replacement Surgery Fellow
Ansab Khwaja, MD, was born in Karachi, Pakistan, and moved to Seattle with his family when he was 10 years old. While receiving a degree in philosophy from the University of Washington, he worked with the school’s athletic trainers, giving him his first glimpse into orthopaedics. He earned early distinction as the ‘Outstanding First Year Sports Medicine Intern.’ He then remained at the University of Washington for medical school where he was a leader in the Orthopaedic Interest Group and his extensive volunteerism earned him a community service award.

Predictors of Physical Abuse in Elder Patients with Fracture
Elder abuse is a public health issue requiring attention. Unlike abuse in the pediatric population, predictors of elder abuse in patients with fracture have not been well defined. Elderly patients with physical abuse and fracture were abstracted using the 2007 to 2017 National Emergency Department Sample database. Univariate comparisons, multivariate regression, and adjusted odds ratios were used to determine independent predictors of elder abuse compared with nonabuse fracture controls.
