Postdysenteric arthropathy, unspecified knee
ICD-10 M02.169 is a billable code used to indicate a diagnosis of postdysenteric arthropathy, unspecified knee.
Postdysenteric arthropathy refers to a type of inflammatory arthritis that occurs following an episode of dysentery, typically caused by bacterial infections such as Shigella or Salmonella. This condition primarily affects the knee joint, leading to pain, swelling, and stiffness. Anatomically, the knee joint comprises the femur, tibia, fibula, and patella, with ligaments, tendons, and cartilage playing crucial roles in its function. The pathophysiology involves an autoimmune response triggered by the infection, resulting in synovial inflammation and joint damage. Clinically, patients may present with acute onset of knee pain, limited range of motion, and signs of inflammation such as warmth and swelling. Chronic cases can lead to joint deformities and functional limitations, impacting mobility and quality of life.
Orthopedic documentation should include imaging studies (X-rays, MRIs) to assess joint integrity, functional assessments to evaluate range of motion, and any surgical notes if applicable.
Common scenarios include patients presenting with acute knee pain post-dysentery, requiring joint aspiration or arthroscopy for diagnosis and treatment.
Orthopedic considerations include assessing for joint damage and the need for potential surgical intervention based on severity.
Rheumatologic documentation should include laboratory tests for inflammatory markers (e.g., ESR, CRP) and assessments of disease activity (e.g., DAS28 score).
Patients may present with systemic symptoms alongside knee involvement, necessitating a comprehensive evaluation for autoimmune conditions.
Rheumatologists must consider the potential for systemic involvement and monitor for disease progression.
Functional assessments should document mobility limitations, pain levels, and rehabilitation needs, including any assistive devices required.
Rehabilitation scenarios may involve physical therapy to restore knee function and improve mobility post-arthropathy.
Physical medicine specialists should focus on the patient's ability to perform daily activities and the impact of joint pain on overall function.
Used when joint effusion is present and requires aspiration for diagnostic or therapeutic purposes.
Document the indication for the procedure, joint involved, and any findings during the procedure.
Orthopedic and rheumatologic specialists may perform this procedure to relieve symptoms and obtain synovial fluid for analysis.
Postdysenteric arthropathy is primarily caused by an autoimmune response following a dysentery infection, leading to inflammation in the joints, particularly the knee.
Differentiation can be made based on the patient's history of dysentery, the timing of joint symptoms following the infection, and specific laboratory findings that indicate inflammation.
