Patient question
My kneecap dislocated and is still out of place. What should I do?
Quick answer
A kneecap that stays out of its groove needs emergency care: keep the knee in the most comfortable position, do not force it back, and call 999 or go to the nearest emergency department. Once it is back in place, arrange imaging and a specialist review, says Dr. Pablo Gelber, knee surgeon at Aman Hospital, Doha.
Right now: the safe steps
- Stop moving and sit or lie down with the leg supported in whatever position hurts least, often slightly bent
- Do not let anyone pull, twist or push the kneecap; repeated attempts can damage cartilage
- Apply a cold pack wrapped in cloth over the side of the knee
- Call 999 or have someone take you to the nearest emergency department
- Do not eat or drink if you are told you may need sedation
What happens in the emergency department
A doctor usually gives pain relief and then gently straightens the knee while guiding the kneecap back into its groove. This is often quick once the muscles relax. X-rays are then taken to confirm the position and check for a small piece of bone broken off during the injury.
You will usually leave with a support or brace, crutches if needed, and advice to see a knee specialist within the next days.
Warning signs that need urgent attention
- The foot becomes cold, pale, numb or tingling
- Pain becomes much worse after the kneecap is back in place
- The knee balloons quickly and feels tense
- You cannot lift the straight leg off the bed at all, which may point to a different injury such as a tendon rupture
The follow-up appointment in Doha
Within a week or two, book a specialist review. At Aman Hospital, Dr. Gelber examines the knee once the first pain has settled, looks at the emergency X-rays and usually arranges an MRI to check the ligament, the cartilage and any loose fragment. Treatment is then planned: most first dislocations without a fragment are treated with physiotherapy, while a large loose piece may need early keyhole surgery.
Frequently asked questions
My friend says he can pop it back. Should I let him?
It is safer not to. The kneecap sometimes goes back as the knee straightens, but forcing it without pain relief and X-rays risks extra cartilage or bone damage and misses fractures.
It went back in on the way to hospital. Do I still need to go?
Yes, you still need an assessment and X-rays, ideally the same day, and then a specialist review. A dislocation that reduces on its own can still leave a loose fragment.
