Metabolomic Phenotypes Reflect Patient Sex and Injury Status: A Cross-Sectional Analysis of Human Synovial Fluid.

Background: Post-traumatic osteoarthritis (PTOA) is caused by knee injuries like anterior cruciate ligament (ACL) injuries. Often, ACL injuries are accompanied by damage to other tissues and structures within the knee including the meniscus. Both are known to cause PTOA but underlying cellular mechanisms driving disease remain unknown.

Benefits of Implementing an Enhanced Recovery After Surgery Protocol in Ambulatory Surgery.

Background: Enhanced recovery after surgery (ERAS) protocols in orthopaedic surgery have garnered significant focus due to their ability to control pain adequately in the immediate postoperative window, allowing for earlier mobilization, shorter hospital stays, and fewer complications. Virginia Commonwealth University created a multimodal pain management approach in which patients receive a preoperative femoral nerve block followed by periarticular intraoperative local injection anesthesia consisting of bupivacaine, ketamine, and ketorolac.

Hypothesis: We hypothesized that implementation of the ERAS protocol will decrease postoperative pain scores, decrease recovery time in the postanesthesia care unit (PACU), and decrease opioid use in anterior cruciate ligament (ACL) reconstruction.

Prosthetic Joint Infection due to in a Patient from Trinidad: Workup, Pathology, and Treatment.

is a rarely reported cause of prosthetic joint infections. This current case report is of a patient from Trinidad, with a history of a right total knee replacement (TKR), who underwent a successful two-stage revision due to a periprosthetic joint infection (PJI). This case report offers a unique treatment plan to successfully treat periprosthetic joint infections and emphasizes the importance of obtaining an accurate travel history.

Conversion of Total Shoulder Arthroplasty to Reverse Total Shoulder Arthroplasty: Time to Conversion and Indications at a Tertiary Care Center.

Anatomic total shoulder arthroplasty (aTSA) and reverse shoulder arthroplasty (RSA) are increasingly common, with volume projected to increase over 90% by the year 2025. Therefore, it is critical to understand the expected longevity of aTSA using modern implants and techniques, rates of conversion to RSA, and most common indications for conversion if surgeons are to properly diagnose and treat patients. A retrospective review was conducted of 800 patients who had undergone aTSA, RSA, or hemiarthroplasty (HA) between 2015 and 2019 at a tertiary-care academic medical center.
