Hydrodistension injections

Cortisone Injection knee

What are hydrodistension injections?

Hydrodistension injections injections are performed under ultrasound guidance with the aim of precisely depositing anti-inflammatory steroid, local anaesthetic and saline to give pain relief whilst also deliberately stretching the lining of the joint (joint capsule).

This procedure is increasingly used in the treatment of ‘frozen shoulder’ (adhesive capsulitis) and has been shown to be effective in the majority of patients by giving pain relief and also helping them to regain movement.

These injections can give rapid and effective reduction in pain and inflammation; however, improvements are usually temporary. As with all medicines, some people may experience side effects.

I have no hesitation in highly recommending Rob Mast. He saw my 87 year old father on two occasions. At the first appointment he administered a steroid injection and at the second appointment he assessed a hamstring issue. On both occasions he was patient, respectful and thorough. The steroid injection proved successful in significantly reducing pain in my father's arthritic knee. On the second visit Rob spent an hour assessing my father's hamstring and determined an injection would not resolve the issue. If you are looking for an honest, thorough and experienced practitioner Rob is a good choice.

I went to see Rob with chronic right shoulder pain. He took plenty of time to examine and scan me. The injection was painless, and I now have exercises which will hopefully mean I can get back on track with my strength training. Thank you.

I booked a visit to Sonoscope Ltd Ultrasound Guided injections for my 87 year old mother, as she was having severe discomfort with one of her knee joints and we couldn't get to see her local NHS GP within a reasonable timeframe.Robert Mast at Sonoscope kindly saw my mother with a few days of making the appointment . Excellent service and superb bedside manners. Made my mother feel at easy and the steroid injection administered under Ultrasound worked brilliantly. Literally the next day my mother started to feel the benefits of the treatment. I would highly recommend Robert and his clinic to anyone needing help with pain relief.

My wife suffered with shoulder pain for ages. A friend of ours recommended ultrasound shoulder steroid injections, so i searched for ultrasound guided injections near me and Sonoscope popped up. I called and i spoke directly with Rob who is the one who performs the ultrasound guided injections and was able to answer all my questions in lay terms so my wife and i were able to make an informed decision and go ahead with the procedure. Before the steroid injection, Rob examined my wife and diagnosed my wife's issue as a frozen shoulder. During the ultrasound injection procedure, Rob was amazing, and you could sense that he was a very experienced clinician. If you are looking for an ultrasound guided injection with a true expert, Rob from Sonoscope should be your first port of call.

Great experience, I took my elderly nan for inflamed arthritis of the knee. She’s been in a lot of pain and discomfort.Rob is great, explains everything clearly. My nan is very happy. She only got one knee done. Now she’s saying She wants to go back to see Rob to do her other knee. Friendly, informative and efficient service. We’d highly recommend. Great service.

Rob was amazing.He kept me informed and explained the procedure step by step, happy to answer my never-ending questions.This helped immensely as it was the 1st time having this treatment and therefore was pretty nervous. Robs friendliness and reassurance kept me calm and would highly recommend him.

I would like to say how professional Robert Mast was in dealing with my Mum’s painful knee problem. We got the appointment within 36 hours, and Robert was not only very informative regarding the treatment, but was most helpful in suggesting some alternatives to consider for the future. I would not hesitate to recommend Robert for his expertise and patient care.Marilyn Cunningham26 March 2022

I found Robert to be very professional, and he gave great advice to me for my ongoing knee injury. I had a very thorough ultrasound during which everything was explained concisely and in great detail. Afterwards a full write up was sent to me with details, and strengthening exercises and advice. I would highly recommend Sonoscope.co.uk, and would definitely go back with any future injuries. Thank you Robert

I was referred to Sonoscope by my Physio after having several sessions of treatment on my shoulder without satisfactory success. I was very apprehensive having not had this type of treatment before, however, my worries were totally misplaced. Filling in the pre-treatment form was a little tedious but once you get into the clinic and meet Rob Mast you begin to relax. He endeavour's to explain everything in lay mans terms, and walks you through the whole procedure. He warns you the injection might hurt, but in all honesty, I'm a bit of a wimp, but the pain was far less than I had to bear continually from my shoulder/hand and was really not bad at all. The injections began to work quite quickly for me so I am over the moon and would have no worries whatsoever in returning for more treatment. I have never been more willing to recommend anybody before.

Rob's Ultrasound screen visual of my damaged shoulder was very enlightening, he identified the areas of my shoulder that were of concern and suggested what the best treatment would be. The session was clear and precise and I would recommend Sonoscope Ultrasound

I was pleased with the treatment that I received to my shoulder. Rob Mast was professional and punctual and took time to explain his opinion to me and what were the uncertainties involved.I attended for injection into the glenohumeral joint for frozen shoulder (6 months since onset) but because I was experiencing extreme pain at a different part of my shoulder (2 days since onset) he took the trouble to understand this new event and offer the cortisone injection in a different location. This injection alleviated the pain and I was able to return two weeks later for the planned frozen shoulder injection.

My Dad first used Rob for an injection in his knee which worked really well and has significantly improved his mobility and pain. I have used Rob for 'acute tennis elbow' and have had a similar response.Rob is very professional and takes the time to explain what he is looking at on the ultrasound and what he is doing to do and why.I would certainly recommend.

I saw Rob with a frozen shoulder, which he ultrasounded then injected. He was very thorough, kind, and professional. He explained what he was doing and why, and I feel very confident in his skills. My shoulder improved a huge amount after, and I can 100% recommend him.

Would highly recommend Rob, he seemed to be an expert in his field. Was told my shoulder would need an MRI after I had the guided injection to ease my pain. The MRI appointment was handled by Rob and the appointment was set up within the week. I am just waiting on my results of this and am hopeful I will very soon be pain free. Highly recommend. Five star service.

Good experience, expertly handled by Robert Mast. He quickly identified the problem on my foot whilst pointing out to me on the ultrasound device the extent of the inflammation . He pinpointed the entry for injection very accurately , and I have experienced little or no pain thereafter. Hopefully this will work for several months, and once another jab was needed , there or elsewhere in my joints, would not hesitate to go back.

I recently had an ultrasound injection at the clinic and was very pleased with the service I received. People were friendly and helpful and the procedure was carried out in a professional and client friendly manner by Robert Mast. Procedures were explained as they were being carried out with the opportunity to ask for further information and/or clarification. I would most definitely go back for further treatment, if required.

I saw Dr.Mast at the London clinic, as I have an injury on my right foot and waiting times for the NHS are impossible at the moment. I was given an appointment quickly (thankfully, as the pain was getting unbearable!) and him and his nurse were attentive and professional. He explained what he was seeing on the ultrasound scan and the steroid injection went without incident. I will be going back in 6-8 months as needed!

Extremely professional with the best advice i could have had for my Frozen shoulder. Was very well informed about coarse of treatment and it was administered perfectly. Have laready recommmended to family.
I was really impressed with Rob Mast. He gave me a steroid injection in the hip which I was due to have on the NHS but I didn't wish to wait several months. I have quite a bit of hip history and bombarded Rob with a lot of information and he's pretty much the only person, aside for the surgeon, who has comprehended it accurately! He listens intently and you get the feeling he's really trying to get it right. A very pleasant, mellow person too. You'll be in great hands!

As a keen club runner - having run over 18 full marathons and 2 ultra-marathons - Rob’s combined expert physiotherapy and ultrasound guided injection skills have allowed me to compete at 3 ‘A race’ events over the past 10 years. Without his specialised ultrasound guided injection skills, two separate knee and an ankle injury would have prevented me from running and wasted months of training. I would recommend Rob unreservedly.

I had a chronically inflamed bursa in my shoulder for almost two years. Nothing helped. I had injections done as well but still no help. I walked around with pain for a long time and had trouble sleeping.I then had an injection at Sonoscope. The ultrasound guided injection was done by Rob who clearly knew his stuff and explained the injection in detail. He made me feel at ease. The injection was almost painless and exactly into the bursa. Within a week I was pain free! This allowed me to progress further with exercises. He would highly recommend his services !(Bob)

What is included in our ultrasound guided injection fees?

How successful is it?

Several studies have shown that ultrasound guided shoulder joint hydrodistention can help reduce patients’ pain and improve their range of motion. This technique is performed under aseptic conditions and a local anaesthetic is injected into the shoulder joint usually combined with a steroid joint and the needle is guided by the ultrasound images.

Will it be painful?

You may feel mild discomfort during the procedure and a fullness or heaviness as the joint is filled. After the examination, you may experience swelling and discomfort. These symptoms usually disappear after 48 hours and, if necessary, you may take your usual painkillers.

What are the risks and the benefits of this procedure?

The benefit of this treatment is that it should reduce the pain and discomfort in your shoulder and help with movements.  There is a small risk of infection when a needle is placed in a joint but we minimise the risk by using an aseptic technique. However, if you experience redness, persistent pain or swelling after the procedure, you should contact your GP or go to your nearest accident and emergency department.
