Altman's Clinical Criteria for Hip OA

sen=0.86, spec 0.75

How I remember this:
1. Hip OA has 5 letters, so there are 5 criteria
2. Typically, your hips come in a pair (I'm adding an S to get all 5 criteria in)

P: PAIN, in the hip
A: AGE > 50 y/o
*IR: < 15 degrees, and PAIN with IR
S: stiffness in the morning up to 60 minutes

*there are two criteria
