Osteoarthritis Disease Severity In The Temporomandibular Joint And The Knee Joint: A Comparative Cadaveric Study, Jessica A Immonen, Jason Ciccotelli, Linh M Nguyen, Lesley Gilmer, Landen Broadhead, Mackenzie Kitchen, Conner Paul, Jeremy James

Journal Articles

OBJECTIVE: The objective of this study was to determine the level of disease severity in a pilot cohort of temporomandibular joints (TMJs) and compare them to the pathology findings previously characterized in cadaveric knee joints.

DESIGN: Thirty-one intact TMJs from 17 cadaveric donors were harvested and arthritic lesioning seen in the knee joint was investigated on the condyle and the fossa of the TMJ. Prevalence of gross alterations was equated and disease severity was determined for sex- and age-based donor pools using a validated, osteoarthritis (OA) disease severity scale (DSS). Knee joint DSS scores were also compared to the TMJ …

Minoxidil Weakens Newly Synthesized Collagen In Fibrotic Synoviocytes From Osteoarthritis Patients, Stefan Sarkovich, Peter P. Issa, Andrew Longanecker, Davis Martin, Kaitlyn Redondo, Patrick Mcternan, Jennifer Simkin, Luis Marrero

Purpose: Synovial fibrosis (SFb) formation and turnover attributable to knee osteoarthritis (KOA) can impart painful stiffness and persist following arthroplasty. To supplement joint conditioning aimed at maximizing peri-operative function, we evaluated the antifibrotic effect of Minoxidil (MXD) on formation of pyridinoline (Pyd) cross-links catalyzed by Plod2-encoded lysyl hydroxylase (LH)2b that strengthen newly synthesized type-I collagen (COL1) in fibroblastic synovial cells (FSCs) from KOA patients. MXD was predicted to decrease Pyd without significant alterations to Col1a1 transcription by FSCs stimulated with transforming growth factor (TGF)β1. Methods: Synovium from 10 KOA patients grouped by SFb severity was preserved for picrosirius and LH2b …

Osteoporosis In The Setting Of Shoulder Arthroplasty: A Narrative Review, Mohammad Daher, Mohamad Fares, Peter Boufadel, Akshay Khanna, Ziad Zalaquett, Joseph A. Abboud

Rothman Institute Faculty Papers

Patients who undergo shoulder surgery are frequently affected by osteoporosis and osteopenia, and the prevalence of this association is expected to increase due to the growing number of elderly individuals undergoing these procedures. It may be advisable to conduct a preoperative DXA scan for orthopedic surgical candidates at high risk, to detect those who could benefit from early intervention and avoid any related adverse events. Some of these complications include periprosthetic fractures, infection, subsequent fragility fractures, and have an all-cause revision arthroplasty at 2 years post-op. Some studies analyzed the beneficence of antiresorptive medications pre-operatively but the latter did not …

Assessing Inflammation In The Pathology Of Knee Osteoarthritis, Zachary J. Koudys

Electronic Thesis and Dissertation Repository

Osteoarthritis (OA) is a joint disease that causes pain, stiffness, and loss of function. Inflammation of the synovium plays a role in the pathology of OA. Macrophages are the dominant immune cells in synovial tissue. Activated macrophages over-express the translocator protein (TSPO). [¹⁸F]FEPPA is a 2^nd generation positron emission tomography (PET) tracer that can target TSPO with high specificity. Hybrid [¹⁸F]FEPPA PET/MRI may enable accurate quantification of macrophage activity in vivo. In this work, [¹⁸F]FEPPA tracer uptake in knee synovial tissue was measured ex vivo using autoradiography and was validated to correlate to …

Hemoglobinopathy Is Associated With Total Hip Arthroplasty Indication Even Beyond Sickle Cell Anemia, Maxwell J. Rakutt, Daniel N. Bracey, Anna Cohen-Rosenblum, Peter K. Sculco, Franco M. Sabatini, Cale A. Jacobs, Stephen T. Duncan, David C. Landy

School of Medicine Faculty Publications

Background: The extent to which hemoglobinopathies other than sickle anemia (HbSS) are associated with hip osteonecrosis is unknown. Sickle cell trait (HbS), hemoglobin SC (HbSC), and sickle/β-thalassemia (HbSβTh) may also predispose to osteonecrosis of the femoral head (ONFH). We sought to compare the distributions of indications for a total hip arthroplasty (THA) in patients with and without specific hemoglobinopathies. Methods: PearlDiver, an administrative claims database, was used to identify 384,401 patients aged 18 years or older undergoing a THA not for fracture from 2010 to 2020, with patients grouped by diagnosis code (HbSS N = 210, HbSC N = 196, …

Mesenchymal Stem Cell Use In The Treatment Of Osteoarthritis: A Literature Review, Samantha Arrizon, Nolan Barnes, Teresa Del Toro, Lei Wena Herme, Vanessa Mendoza, Thi Tran, Reeta Zamro

Physician Assistant Studies | Literature Reviews

Mesenchymal stem cell (MSC) therapies have been growing in popularity in research due to their anti-inflammatory, immunomodulatory, and regenerative properties. Many ongoing clinical trials are investigating the safety and efficacy of MSC therapies to treat osteoarthritis, also known as “wear and tear” arthritis. As the average life expectancy increases, with age people are more prone to developing this disease, therefore, increasing its prevalence. This condition is progressive and will lead to functional decline, decreased quality of life, and increased medical costs. Our focus is to discuss the efficacy of mesenchymal stem cell injections in alleviating pain, improving functionality, and slowing …
