,Executive Case Summary
Encounter Overview & Chief Complaint
Chief Complaint: "My left knee started hurting terribly two nights ago, and now it’s
so swollen and painful I can’t even put weight on my leg or let the bedsheet touch it."
Executive Case Summary: Mr. Chester Wilson is a 57-year-old male who presents
with a 48-hour history of acute, rapidly progressive, severe left knee pain, swelling, ery-
thema, and localized warmth. The onset occurred suddenly during sleep following a
weekend gathering where he consumed moderate-to-high amounts of red meat and beer.
He reports no preceding direct physical trauma, fever, chills, rash, or concurrent involve-
ment of other joints. His past medical history is significant for primary essential hyperten-
sion (managed with Hydrochlorothiazide 25mg daily) and moderate hypertriglyceridemia.
Physical exam reveals an intensely erythematous, warm, exquisitely tender left knee joint
with a demonstrable fluid wave and significant restriction of active and passive movement.

localized warmth, Septic Arthritis must be immediately excluded via diagnostic arthro-
centesis prior to initiating systemic corticosteroid or immunosuppressive therapy. Joint
destruction can occur rapidly within 24-48 hours if bacterial infection is missed.
Primary Learning Objectives
1. Systematic History & Risk Analysis: Identify classic dietary, pharmacological,
and physiological triggers for acute crystalline arthropathies, specifically evaluating
thiazide diuretic use, alcohol ingestion, and purine loading.
2. Target Physical Assessment: Perform precise musculoskeletal physical maneu-
vers (patellar tap test, ballottement, passive vs. active ROM) to differentiate intra-
articular joint effusions from periarticular cellulitis or bursitis.
3. Synovial Fluid Analysis: Interpret polarized light microscopy, WBC count with
differential, Gram stain, and crystal pathology.
4. Evidence-Based Therapeutics: Formulate acute pharmacological strategies (Colchicine,
NSAIDs, Corticosteroids) while navigating renal and cardiovascular comorbidities.
