In the history of the patient with joint pain we have to 
know whether or not the joint pain is mechanical or inflammatory, 
acute or chronic and traumatic or non-traumatic. In the physical 
examination of the patient, it should be determined whether or not 
the origin of the pain is articular, peri-articular, extra-articular or 
referral. In case of articular pain, the pain can be due to Arthralgia, 
Arthrosis (osteoarthritis) or Arthritis. For the detection of arthritis, 
we need at least two points from below items along with tenderness 
of joint; swelling: 2 points, warmth: 1 point, limitation of motion: 1 
point and redness: 1 point. We have to know three data regarding 
patient including: Age, Sex and Race. We have to evaluate ten key 
items regarding arthritis including: 1- The confirmation of arthritis 
2- Acute versus chronicity 3- Mono, oligo or polyarticular typing 4- 
Symmetric versus asymmetric typing 5- Migratory, additive or 
synchronized pattern 6- Small versus large joint involvement 7- 
Upper limb versus lower limb involvement 8- The presence of axial 
involvement 9- The presence of muscle involvement 10- The 
presence of extra musculo-skeletal (systemic) involvement. For 
approaching towards joint pain we follow two rules called “The 
Rules of Ninety five percent”. The first rule represents us that, the 
role of history, physical examination and Para-clinics in diagnosis 
is 60%, 30% and 5% respectively. The second rule shows us that in 
the medicine the 95% is actually equal to 100%. These above two 
rules are accurate in 95% of the cases and this was “2016 Novel 
Guideline” approaching towards joint pain.
