Joint inflammation caused by streptococcal bacteria spreading to the joints.
Because streptococcal arthritis is rated under whichever joint formula applies to your specific situation, the evidence that helps is evidence tied to the criteria for that underlying formula. Medical records documenting the affected joint or joints, the cause of the arthritis, and the course of treatment are a starting point. Range-of-motion measurements from a physical examination are central to any limitation-of-motion rating, so records showing how far you can move the joint and whether pain limits motion matter directly.
If the joint has been surgically replaced or resurfaced, operative reports, hospital discharge records, and follow-up notes showing the date of the procedure and your recovery are relevant. If ankylosis is involved, examination findings showing the position in which the joint is fixed and how close your fingers can come to the palm or thumb pad are directly tied to the favorable or unfavorable ankylosis criteria. Statements describing how joint problems affect your daily activities and work can help show the functional impact of your symptoms.
