- Kocher criteria for children for septic arthritis:
- nonweight bearing on affected side
- ESR > 40
- WBC > 12,000
- likelihood of septic arthritis with Kocher criteria if you have:
- 4/4- 99.6%
- 3/4- 93.1%
- 2/4- 40%
- 1/4- 3%
- 0/4- .2%
- Staph aureus most common organism in septic arthritis and osteomyelitis
