The new EULAR/ACR classification criteria use anti-nuclear antibodies (ANA) as an entry criterion. (Non-infectious) fever is the one new criterion. All criteria items now have individual weights (from 2 to 10) and are structured in domains, within which only the highest item is counted. There is one common attribution rule, counting criteria only if there is no more likely alternative explanation. Ten points are sufficient for classification. The new criteria have reached a sensitivity of 96.1% and a specificity of 93.4%.

ACR Revised Criteria for Early Diagnosis of Knee Osteoarthritis (OA)
Osteoarthritis (OA) is cartilage failure resulting in joint pain and loss of joint functions. Knee OA is the OA of knee that mechanical forces have major effect on initiation and progression of it. Knee OA is the most common disease of knee especially in the middle to old ages. The most common findings in the history and physical examination of the patients with knee OA are mechanical knee pain, gelling knee pain, crepitus on knee motion, bony tenderness and bony enlargement in the joint line. During the flare up of Osteoarthritis, knee can show swelling due to joint effusion called “Hydrarthrosis” that is a mechanical type of synovial fluid.
2017 ACR–EULAR Classification Criteria for Primary Sjögren’s Syndrome

1990 Criteria of ACR for the Classification of Fibromyalgia
Fibromyalgia syndrome (FMS) is conceptualized as a chronic disorder characterized by widespread and persistent non-inflammatory musculoskeletal pain. Concomitant symptoms usually include fatigue, insomnia, morning stiffness, depression, anxiety, and cognitive problems (forgetfulness, concentration difficulties, mental slowness, memory and attention problems, etc.). Furthermore, the majority of FMS patients usually show predominantly negative affect, including neuroticism, alexithymia, and catastrophizing and impaired health-related quality of life.

Revised Criteria for the Classification of Giant-Cell Arteritis (GCA)
Giant Cell Arteritis (GCA) is a systemic vasculitis of the medium and large sized vessels with a tendency to involve extracranial branches of the carotid arteries.
