Recovery & Aftercare Guide

Ultrasound-guided joint injections

Joint or soft-tissue injection performed under live ultrasound guidance for accurate placement.

Important. Your individual instructions from your treating clinician take precedence over this general information. If anything here differs from what your clinician has told you, follow your clinician’s advice and contact the hospital if you are unsure.

Overview

This is a joint or soft-tissue injection performed while the clinician watches the needle on live ultrasound, allowing precise placement.

Guidance is used for deeper or more complex targets, where accuracy matters, or where a previous landmark-guided injection did not help.

The appointment takes around 30 minutes. Aftercare is the same as for a standard joint injection.

Before your procedure

  • Tell the team about all medicines, particularly anticoagulants and antiplatelets. Do not stop prescribed medicine unless instructed.
  • Tell the team if you have diabetes, as injected steroid can raise blood glucose for a few days.
  • Tell the team about any current infection or fever. The injection will usually be postponed.
  • Mention allergies, particularly to local anaesthetic.
  • Eat and drink normally.
  • Wear clothing that gives easy access to the area, as ultrasound gel is applied directly to the skin.
  • Arrange transport if a weight-bearing joint or your driving leg is being injected.

What happens on the day

  1. The area is scanned first so the clinician can see the target and plan the approach.
  2. The skin is cleaned and ultrasound gel applied. Local anaesthetic may be used.
  3. The needle is advanced under live ultrasound view. You may feel pressure and brief discomfort.
  4. Placement is confirmed on screen before the medication is delivered.
  5. You may be observed briefly, then given written aftercare before leaving.

Aftercare

Immediate numbness

If local anaesthetic was used, the area may feel better immediately and then ache again as it wears off.

Post-injection flare

Increased pain for 24 to 48 hours affects some people. Rest, ice over clothing and simple pain relief usually settle it.

Rest

Rest the area for 24 to 48 hours and avoid loading it heavily.

Activity

Gentle movement is encouraged. Avoid high-impact activity and heavy lifting for around 2 weeks.

Physiotherapy

Continue or begin rehabilitation as advised. Accurate placement is most valuable when combined with rehabilitation.

Driving

Do not drive immediately afterwards if your driving leg was injected or the area feels numb.

Diabetes

Monitor blood glucose more closely for several days if you have diabetes.

Follow-up

A review is usually arranged to assess benefit and plan next steps.

Typical recovery timeline

Timings are typical and vary between individuals.
WhenWhat to expect
First 24 hoursPossible short-lived relief from local anaesthetic, then aching returns.
Days 1 to 2Post-injection flare possible. Rest and simple pain relief.
Days 3 to 7Anti-inflammatory effect usually begins.
Weeks 2 to 6Peak benefit and the best window for rehabilitation.
Weeks 6 onwardsBenefit may persist for weeks to months. Review to plan next steps.

Frequently asked questions

Why use ultrasound guidance?

It allows the clinician to see the needle reach the intended target, which matters most for deeper or more complex sites.

Does it hurt more than a standard injection?

No. The experience is similar. Gel is applied to the skin and the scan itself is painless.

Is the aftercare different?

No. Aftercare is the same as for a standard joint injection.

Will I see the scan?

You can usually see the screen and the clinician can explain what is being shown.
