His symptoms have progressively worsened over the past several years. He has a past medical history of obesity, type II diabetes mellitus, smoking, and hypertension. He drinks roughly ten beers per day. His current medications include metformin, insulin, lisinopril, and hydrochlorothiazide. The patient has a recent travel history to Bangkok where he admits to having unprotected sex. On physical exam, examination of the lower extremity results in pain. There is crepitus of the patients hip when his thigh is flexed and extended. Which of the following is the most likely diagnosis?? A: Osteoarthritis, B: Rheumatoid arthritis, C: Infectious arthritis, D: Gout, E: Pseudogout,  <response>: Based on the information provided in the question stem, the most relevant details are:- 69 year old male with progressively worsening pain primarily in the left great toe but also in the hips and knees, worse with activity and improves with rest - Past medical history of obesity, type 2 diabetes, smoking, hypertension- Drinks 10 beers per day- Crepitus in the hip joint- Recent travel to Bangkok with unprotected sexThis clinical presentation is most consistent with osteoarthritis given the patients age, chronic joint pain worse with activity, crepitus on exam, and risk factors of obesity and diabetes. The distribution of pain in the great toe and other joints also points more towards osteoarthritis rather than rheumatoid arthritis. There is no evidence to suggest infectious arthritis given the chronicity and lack of systemic symptoms. The alcohol use raises suspicion for gout but the distribution and presentation is not classic.A: Osteoarthritis
