Joint impediment disorders

Where they diverge

Traditional concepts do not map one-to-one onto modern diagnoses. Read the divergence note first.

The traditional concept is broader. It is defined not as a disease entity but as a mechanism (obstruction of qi and blood by wind, cold, damp and heat) together with a symptom cluster, so it unites conditions that ICD-11 separates by aetiology and by chapter. Comparing Korean clinical guidelines alone, it spans autoimmune arthritis and degenerative joint disease, and extends to chemotherapy-induced polyneuropathy, a neurological condition. Conversely it encodes none of the variables on which modern arthritis care turns. ICD-11 rheumatoid arthritis requires a composite score across joint count with synovitis, serology, acute-phase reactants and symptom duration; gout requires demonstration of urate crystals in synovial fluid. Neither enters the traditional diagnosis.

Research confidence: medium-high. The full assessment, in Korean, is in docs/PATTERN_RESEARCH_KCD_DISEASES.md.
The modern correspondences come from literature research, not from an official KCD or KTKP mapping, so the highest mapping confidence is not assigned.
Full evidence and citations are in docs/PATTERN_RESEARCH_KCD_DISEASES.md.
KCD does not carry the Donguibogam volume, so it is left blank here. It needs checking against the original text.

Signs that need immediate medical assessment

A single joint that becomes acutely red, swollen, hot and painful — especially with fever — must be treated as septic arthritis until proven otherwise, with urgent joint aspiration and culture, rather than managed conservatively under this traditional category. Sources: Coakley G, Mathews C, Field M, et al. BSR & BHPR, BOA, RCGP and BSAC guidelines for management of the hot swollen joint in adults. Rheumatology (Oxford) 2006;45(8):1039-1041. PMID 16829534, doi:10.1093/rheumatology/kel163a; Weston V, Coakley G, et al. J Antimicrob Chemother 2006;58(3):492-493. PMID 16857687, doi:10.1093/jac/dkl295 (revision in progress: Arumalla N, et al. Rheumatol Adv Pract 2025;9(3):rkaf058, PMID 40524816). The guidelines direct that acute spontaneous swelling of a single joint, usually of less than two weeks' duration, be managed as septic arthritis until proven otherwise.
