Retrospective Study: Time to Positivity Rates of Cultures for Microorganisms Associated with PJI
The Journal of Bone and Joint Surgery published a retrospective study investigating the time to positivity (TTP) for pathogens commonly encountered in patients with periprosthetic joint infection (PJI). TTP on culture media was recorded and compared to different microbial species in 536 PJI patients. The mean number of positive cultures was 3.9, and gram-negative organisms grew significantly faster on culture compared with gram-positive organisms. Methicillin-resistant Staphylococcus aureus grew the fastest (mean TTP = 1.42 days) followed by gram-negative rods (1.92 days) and methicillin-sensitive Staphylococcus aureus (1.95 days).
Study Investigates Incidence of Posteromedial Tibial Plateau Bone in Patients with Multiligament Knee Injuries and an Intact ACL
In a study published online in Arthroscopy, posteromedial tibial plateau (PMTP) bone bruising was observed in 66.7 percent of patients with meniscus ramp lesions (MMRLs). The main outcome measurements included incidence of MMRLs and PMTP bone bruises in patients with an intact ACL who received MRI scans within 90 days of injury. Overall, 221 patients with multiligament knee injuries (MLKIs) were retrospectively reviewed, of which 14.5 percent had an intact ACL. PMTP bone bruises and MMRLs were observed in 37.5 percent of patients. The most common MLKI was combined injury to the posterior cruciate ligament and posterolateral corner (84.4 percent).
Study: Association between Anterior Talofibular Ligament Remnant Quality and Recurrent Instability after Arthroscopic Ankle Ligament Repair
A retrospective study assessed whether the signal intensity of the anterior talofibular ligament and ligament remnant quality are associated with recurrent ankle instability after arthroscopic lateral ankle ligament repair in 67 patients. The study was published in Knee Surgery, Sports Traumatology, Arthroscopy. Patients with a high anterior talofibular ligament signal intensity via MRI had higher rates of recurrent ankle instability. Compared with those patients with present anterior talofibular ligaments, patients with absent anterior talofibular ligaments had higher rates of recurrent ankle instability.
Study: Preoperative Reimers Linked to Avascular Necrosis in Children with Cerebral Palsy undergoing Hip Containment Surgery
A retrospective study published online in the Journal of Children’s Orthopaedics assessed the rate and risk factors associated with avascular necrosis after hip containment surgery in children with cerebral palsy. Reimers migration percentage, neck shaft angle, epiphyseal shaft angle, acetabular index, center edge angle, and acetabular angle were measured in 223 hips and 154 patients. Overall, the rate of avascular necrosis was 26.7 percent. High preoperative Reimers migration percentage was found to be a significant predictor of the development of postoperative avascular necrosis in these patients.
Podcast: AAOS Members Can Present a United Front when Advocating in a Politically Fragmented Environment
AAOS Advocacy Council Chair Douglas Lundy, MD, MBA, FAAOS, was joined by former AAOS President Gerald R. Williams Jr, MD, FAAOS, on an August episode of the AAOS Advocacy Podcast to discuss unity among members amidst divisive political and social events. Dr. Lundy encouraged members to become involved politically in their personal lives while also remaining committed to acting as a unified voice on issues regarding musculoskeletal health and orthopaedic issues affecting patients.
