- dislocated patella is a very common ED presentation in the adolescent and young adult in particular.
- classically they present by ambulance with it still dislocated and holding a Penthrane analgiser stick.
- diagnosis is clinical and is usually very obvious that the patella is dislocated
- most patients can be rapidly managed by simple closed reduction even whilst on ambulance trolley while they breathe on the Penthrane
- reduction is achieved by pushing medially on the lateral aspect of the patella with your thumbs while an assistant extends the knee
- Xray with patella sky-line views should be done to exclude osteochondral avulsion fragments which can be large and may require operative Mx if present.
- patients with no significant fracture are usually discharged home with Zimmer splint, crutches and analgesics and advised to have physiotherapy follow up to reduce the risk of subsequent dislocations.
