Background
- Occurs when pivot knee on fixed leg
Diagnosis
- Petella is usually displaced laterally; knee is held in flexion

- Usually seen at lateral femoral condyle or medial margin of patella
Treatment
- Reduce; do not need x-rays prior to reduction
- Extend knee and slide patella back into place
Disposition
- Ortho with orthopedic followup within 1-2wks
- Knee immobilizer, NSAIDs, partial weightbearing
- If unable to reduce obtain immediate ortho consult
