NGF-Responsive Neurons Are Sensitized in Experimental Osteoarthritis
Background/Purpose: Nerve growth factor (NGF) is under investigation as a promising target for osteoarthritis (OA) pain. NGF exerts its potent pro-algesic effects through sensitization of…Abstract Number: 0081 • ACR Convergence 2020
Prevalence of Systemic Autoimmune Diseases in Polycystic Ovary Syndrome
Background/Purpose: Polycystic ovary syndrome (PCOS) is characterized by hormonal abnormality, chronic anovulation, hyperandrogenism, and obesity. Due to the hormonal imbalance, we hypothesize that patients with…Abstract Number: 0609 • ACR Convergence 2020
Impact of Depressive Symptoms, Anti-depression Treatment on Direct Medical Costs Among Medicare Beneficiaries with Knee Osteoarthritis (KOA)
Background/Purpose: Depressive symptoms are prevalent among knee OA (KOA) patients and likely lead to additional medical costs. We sought to quantify the prevalence of depressive…Abstract Number: 0934 • ACR Convergence 2020
Warfarin Use and Risk of Knee and Hip Replacements
Background/Purpose: Vitamin K is an essential co-factor in the post-translational gamma-carboxylation of glutamic acid to form gamma-carboxy-glutamic acid (Gla) residues. This confers functionality to vitamin…Abstract Number: 1111 • ACR Convergence 2020
Intra-Articular Mineralization on Knee CT Increases Risk of Knee Pain: The Multicenter Osteoarthritis Study
Background/Purpose: Intra-articular (i.a.) calcium crystal deposition is common in knee osteoarthritis (OA). Low-grade inflammation related to crystals may contribute to knee pain, including pain fluctuation.…Abstract Number: 1458 • ACR Convergence 2020
Slower Current Walking Speed Is Associated with Progression in Radiographic Knee Osteoarthritis: The Johnston County Osteoarthritis Project
Background/Purpose: Poorer physical functioning as a single baseline measurement has been associated with increased risk of radiographic knee osteoarthritis (rKOA) progression, but it is unknown…Abstract Number: 1549 • ACR Convergence 2020
Joint Damage and Malalignment Determine Articular Tenderness More Than Inflammation in Rheumatoid Arthritis, Psoriatic Arthritis or Osteoarthritis in Established Disease
Background/Purpose: To determine whether clinical tenderness can be considered a sign of inflammatory joint activity in patients with rheumatoid arthritis (RA), osteoarthritis (OA) or psoriatic…Abstract Number: 1653 • ACR Convergence 2020
Bilateral vs Unilateral Total Knee Arthroplasty: Racial Variation in Utilization and In-Hospital Major Complication Rates
Background/Purpose: Compared to White Patients, African Americans (AAs) are reported to have lower utilization and higher complication rates outcomes in Unilateral Total knee arthroplasty (UTKA).…Abstract Number: 0099 • ACR Convergence 2020
Interleukin 6 Concentration in Synovial Fluid of Patients with Different Types of Arthritis
Background/Purpose: Persistent synovitis without known markers such as rheumatoid factor (RF), anti-citrullinated protein antibodies (ACPA) as well as without genetic markers as HLAB27 is not…Abstract Number: 0628 • ACR Convergence 2020
Factors Associated with Knee Osteoarthritis in an Outpatient HIV-1 Clinic over a 26 Year Interval
Background/Purpose: With the advent of combined antiretroviral therapy (cART), patients with HIV-1 began living longer and started to develop diseases associated with aging such as…Abstract Number: 0960 • ACR Convergence 2020
The Risk of Venous Thromboembolism After Septic Total Knee Replacement (TKR) Revision Is Double the Risk After Aseptic TKR Revision: An Analysis of Administrative Discharge Data
Background/Purpose: Infection can trigger coagulation pathways and increase the risk of thrombosis. However, the impact of infection on postoperative venous thromboembolism (VTE) risk is poorly…Abstract Number: 1112 • ACR Convergence 2020
Relationship of Depth-Specific Subchondral Bone Mineral Density and Pain in Knee Osteoarthritis: The Multicenter Osteoarthritis Study
Background/Purpose: OA has traditionally been considered a disease of cartilage but early OA changes in subchondral bone may precede cartilage abnormalities. Altered subchondral bone mineral…Abstract Number: 1459 • ACR Convergence 2020
The Association of Frequent Knee Bending with Trajectories of Pain and Physical Function over 8 Years in Knee Osteoarthritis
Background/Purpose: Frequent bending increases loading at the knee and is a risk factor for worsening knee pain associated with knee osteoarthritis (OA). Knee bending is…Abstract Number: 1564 • ACR Convergence 2020
Feasibility of Ultra-low-dose, Short-duration, Total-body Evaluation of Inflammatory Arthritis Using uEXPLORER 18F-FDG PET/CT
Background/Purpose: The uEXPLORER system enables the unique, simultaneous acquisition of PET data over the entire adult human body with a high-sensitivity, alongside concurrent CT data.…Abstract Number: 1654 • ACR Convergence 2020
The Relationship Between Patient-Reported Readiness for Total Knee Arthroplasty and the Likelihood of a Good Outcome at One Year
Background/Purpose: In prior qualitative research, we found that patients with knee osteoarthritis (OA) equated appropriateness for total knee arthroplasty (TKA) with candidacy for the procedure.…
