Osteoarthritis - Symptoms & causes - Mayo Clinic
Osteoarthritis is the most common form of arthritis, affecting millions of people worldwide. It happens when the protective cartilage that cushions the ends of the bones wears down over time.

Osteoarthritis: Symptoms, Diagnosis, and Treatment | Arthritis Foundation
Osteoarthritis can degrade cartilage, change bone shape and cause inflammation, resulting in pain, stiffness and loss of mobility. OA can affect any joint, but typically affects hands, knees, hips, lower back and neck.

Osteoarthritis: Symptoms, Causes, Diagnosis, Treatment
Osteoarthritis is joint pain that comes with wear and tear. Understand the causes, symptoms, diagnosis, and treatments for osteoarthritis.

Osteoarthritis: What It Is, Symptoms & Treatment
Osteoarthritis is a type of arthritis that happens when cartilage in your joints wears down. Without that slippery, smooth shock absorber, your joints can feel stiff, painful or like they’re grinding together when you use them.

Osteoarthritis - Wikipedia
While osteoarthritis is a degenerative joint disease that may cause gross cartilage loss and morphological damage to other joint tissues, more subtle biochemical changes occur in the earliest stages of osteoarthritis progression.

Osteoarthritis - Diagnosis & treatment - Mayo Clinic
Osteoarthritis can't be reversed, but treatments can reduce pain and help you move better. Medicines that can help relieve osteoarthritis pain symptoms include: Acetaminophen. Acetaminophen (Tylenol, others) has been shown to help some people with osteoarthritis who have mild to moderate pain.

Osteoarthritis is a complex condition with a broad range of risk factors. Learn more about osteoarthritis symptoms, types, stages, treatments, and more.

Osteoarthritis - NHS
Almost any joint can be affected by osteoarthritis, but the condition most often causes problems in the knees, hips and small joints of the hands. You should see your GP if you have persistent symptoms of osteoarthritis so they can confirm the diagnosis and prescribe any necessary treatment.

Common Rheumatological Symptoms

Joint Pain (Arthralgia) — Persistent discomfort or soreness in one or more joints caused by inflammation, wear and tear, or underlying autoimmune responses.
Morning Stiffness — Reduced joint mobility and tightness upon waking, often lasting over 30 to 60 minutes in inflammatory conditions like rheumatoid arthritis.
Joint Swelling and Edema — Visible enlargement of affected joints resulting from fluid accumulation in the synovial membrane and inflamed surrounding tissue.
Localized Warmth and Redness — Elevated temperature and erythema skin discoloration surrounding inflamed joints due to increased blood flow from localized inflammation.
Systemic Fatigue — Overwhelming exhaustion and lack of energy caused by ongoing chronic inflammatory cytokine activity throughout the body.
Raynaud's Phenomenon — Temporary color changes in fingers or toes turning white, blue, and red in response to cold or stress due to vascular spasms.
Malar or Butterfly Rash — Red or purplish facial rash spanning across the bridge of the nose and cheeks, classically associated with systemic lupus erythematosus.

Milestones in Rheumatology History

c. 400 BC: Hippocratic Corpus Coining — Hippocrates uses the term "rheuma" to describe body humors flowing into joints, establishing the early classical concept of joint inflammation.
1592: Formal Definition of Rheumatism — French physician Guillaume de Baillou introduces the modern term "rheumatism" to distinguish systemic acute arthritis from localized gout.
1800: Clinical Description of Rheumatoid Arthritis — Augustin Jacob Landré-Beauvais publishes the first detailed clinical description separating rheumatoid arthritis from gout, calling it "asthenic gout."
1859: Naming of Rheumatoid Arthritis — Sir Alfred Baring Garrod formally coins the term "rheumatoid arthritis" to clearly differentiate the inflammatory autoimmune condition from osteoarthritis and gout.
1940: Discovery of the Rheumatoid Factor — Erik Waaler discovers autoantibodies in the blood of patients with rheumatoid arthritis, laying the groundwork for serological autoimmune diagnostics.
1948: Introduction of Corticosteroid Therapy — Philip Hench and Edward Kendall demonstrate the dramatic anti-inflammatory effects of Compound E (cortisone) in treating rheumatoid arthritis, earning the Nobel Prize.
1998: Emergence of Biologic DMARDs — The FDA approves the first TNF-alpha inhibitors, ushering in the modern era of targeted biologic therapies for autoimmune rheumatic diseases.

Current Trends in Rheumatology Research

Chimeric Antigen Receptor (CAR) T-Cell Reset Therapy — Investigating engineered cellular therapies to achieve drug-free, durable clinical remissions by completely depleting pathogenic autoantibodies in severe refractory lupus and systemic sclerosis.
Selective TYK2 and Oral JAK Pathway Inhibition — Developing highly targeted, small-molecule oral inhibitors like deucravacitinib that disrupt specific cytokine signaling pathways while minimizing broader off-target side effects.
Targeted Pathogenic T-Cell and B-Cell Depletion — Evaluating novel biologics, such as rosnilimab and ianalumab, designed to selectively deplete overactive immune cell subpopulations involved in rheumatoid arthritis and Sjögren's disease.
Biomarker-Driven Precision Medicine — Utilizing pharmacogenomics and molecular biomarkers to predict individualized therapeutic responses and match systemic autoimmune conditions to specific biological mechanisms.
Subclinical Interception and Disease Prevention — Identifying seropositive individuals early using high-risk autoantibody profiles to initiate preventive targeted therapies before irreversible joint damage occurs.
Artificial Intelligence and Predictive Disease Modeling — Deploying machine learning algorithms across electronic health records and imaging modalities to forecast inflammatory flares and refine diagnostic accuracy.
