A 22 y.o. male presents to the ED with right knee pain. He noted that he woke up this morning and his right knee was swollen, warm, and very tender. He was unable to bear weight without pain as well. He denied any injuries or trauma to the knee in the last month. He did note he felt chilly in his room this morning, but never measured his temperature. On examination, he is febrile and tachycardic. His right knee is grossly edematous when compared to the left and there is warmth, erythema, and diffuse tenderness. He has limited passive ROM secondary to pain in the knee. His examination is otherwise unremarkable.

76
A 22 y.o. male presents to the ED with right knee pain. He noted that he woke up this morning and his right knee was swollen, warm, and very tender. He was unable to bear weight without pain as well. He denied any injuries or trauma to the knee in the last month. He did note he felt chilly in his room this morning, but never measured his temperature. On examination, he is febrile and tachycardic. His right knee is grossly edematous when compared to the left and there is warmth, erythema, and diffuse tenderness. He has limited passive ROM secondary to pain in the knee. His examination is otherwise unremarkable. You suspect there may be an infection in his right knee.

Arthocentresis (Aspiration) of the knee
Always send the aspirate for culture!
Also remember that a CBC, ESR, and CRP are helpful in this case

A 22 y.o. male presents to the ED with right knee pain. He noted that he woke up this morning and his right knee was swollen, warm, and very tender. He was unable to bear weight without pain as well. He denied any injuries or trauma to the knee in the last month. He did note he felt chilly in his room this morning, but never measured his temperature. On examination, he is febrile and tachycardic. His right knee is grossly edematous when compared to the left and there is warmth, erythema, and diffuse tenderness. He has limited passive ROM secondary to pain in the knee. His examination is otherwise unremarkable. Synovial fluid aspiration confirms infectious arthritis.

A 57 y.o. obese male with a history of Vitamin B12 deficiency and remote alcoholism presents to your office with complaints of foot pain. Around 4 a.m. this morning, he woke up in severe pain. He localized the pain to his big toe on his right foot. He described it as a burning ache saying "it feels like my toe is on fire." Just the lightest touch from even his bed sheets exacerbated the pain. He stated that he was perfectly fine when he went to bed last night, and he denied any trauma or injuries to the foot recently. He denied any fevers, chills, or weight loss. On examination, his 1st MTP on his right foot is significantly swollen, erythematous, and very warm to the touch.
