Hydrodilatation Injection for Frozen Shoulder London
Hydrodilatation is an ultrasound-guided injection used to treat frozen shoulder, a condition where the shoulder becomes painful and stiff due to tightening of the joint capsule. This treatment is designed to reduce pain, improve movement, and support faster recovery when combined with guided exercises and rehabilitation.
At The London Ultrasound Clinic, we carefully select this procedure for patients who have persistent shoulder stiffness or pain, especially when other treatments such as physiotherapy or standard steroid injections have not provided lasting relief. The procedure uses a combination of saline, local anaesthetic, and steroid to gently expand the joint capsule, calm inflammation, and provide immediate pain relief.
What the appointment includes
- A detailed discussion about your symptoms, movement difficulties, and goals.
- Hands-on shoulder examination to assess range of motion and identify areas of restriction.
- Ultrasound assessment of the shoulder joint to visualise the joint capsule and surrounding structures.
- Ultrasound-guided hydrodilatation injection with saline, local anaesthetic and steroid to gently stretch the joint capsule.
- Clear explanation of the findings and step-by-step guidance throughout the procedure.
- A written report including aftercare advice and exercise recommendations to support recovery.
What to expect
The injection is performed under real-time ultrasound guidance to ensure accurate placement of the fluid within the joint capsule. The local anaesthetic helps minimise discomfort, while the steroid reduces inflammation. The procedure gently stretches the capsule and is usually well tolerated. Some temporary discomfort during the injection is normal, but most patients find it manageable.
After the procedure, your clinician will provide clear instructions on safe movement and exercises to maintain and improve shoulder mobility. Most patients can return to normal daily activities shortly afterwards, with ongoing improvement over the following weeks.
How it helps
Hydrodilatation works by physically stretching the tight joint capsule, breaking down adhesions, and reducing pain and stiffness. The combination of steroid and local anaesthetic supports comfort during the procedure and helps settle inflammation. The procedure is most effective when combined with a structured rehabilitation programme, including guided exercises to restore range of motion and strength. Many patients notice gradual improvement in pain and shoulder function within days to weeks, with continued gains over several months.
Common conditions treated with combined injections
Combined ultrasound-guided steroid and hyaluronic acid injections are commonly used for:
- Hip arthritis
- Knee arthritis
- Shoulder arthritis
- Flare-ups of osteoarthritis
- Persistent joint pain with inflammation
Suitability depends on your symptoms, the joint involved, and findings on examination and ultrasound. This is discussed clearly during your appointment.
