EXCELLENT Based on 321 reviews Posted on Google Alison HuntTrustindex verifies that the original source of the review is Google. I saw Marek again for an ultrasound steroid injection for my bursitis. He checked through my notes before arranging an appointment making sure this was ok. When I arrived he was friendly but very professional. He checked where my pain was and whilst injecting me kept asking how I was. After the procedure we chatted about alternative procedures for the future which was good. Would definitely recommend MarekPosted on Google Paul ConneelyTrustindex verifies that the original source of the review is Google. In extreme pain following a rheumatic flare I desperately searched in vain for a steroid injection to my wrist through various NHS providers. In desperation I contacted Physio-Soton and was seen the next day. The service and results were second to none. I received an Ultrasound guided steroid injection and felt immediate relief and the joint has got better each day since. As most people under rheumatology know getting help quickly is almost impossible so this service is a lifeline for those in severe pain and I could not recommend it highly enough. Going from 10/10 pain to mild discomfort in the space of a day is remarkable and Physio-Soton will be the first port of call in future. I am forever grateful for the level of service and clinical expertise.Posted on Google Ross MitchellTrustindex verifies that the original source of the review is Google. Personally I've often been sceptical of reaching of for scans or therapy work due to poor past experiences, however I can say upon visiting Marek this is one of the few places I've been that offer a great service. Clear and direct feedback with open communication made the appointment flow smoothly. I'd highly recommend for anyone who's got some niggles or injures that just don't seem to be healing and you need to know/understand what's going on. ****** 6 stars as google only offers 5.Posted on Google Karen AstonTrustindex verifies that the original source of the review is Google. Had a same week appointment with Marek to have an ultrasound on my ankle where I had concerns of a long ongoing achilles complaint. Marek was very thorough in his assessment and recommended exercises to help relieve. He also provided a thorough report and copies of the scans to share with my GP and NHS specialist I am under. Would definitely recommendPosted on Google SW Southern KarateTrustindex verifies that the original source of the review is Google. I would highly recommend Marek. He’s very professional and approachable. I went to see him with shoulder pain. He did an ultrasound and then administered an injection. Went through everything really well so I knew what to expect during and after the procedure. I will definitely be seeing him again.Posted on Google Tim PonsfordTrustindex verifies that the original source of the review is Google. I initially saw Marek after suffering a sporting injury to my right bicep, elbow and shoulder. He was referred to me by my chiropractor as I was keen to get an ultrasound as quickly as possible. Marek offered me a next day appointment and spent an hour conducting a full and thorough ultrasound of the soft tissue and joints in the affected areas. He was very reassuring and professional, taking his time to explain everything clearly and making sure I understood what he diagnosed. I left feeling much happier and with a clear understanding of what I needed to do to recover. A second follow up appointment built on the first, more reassurance and new exercises to help build up strength and confidence. Overall I would highly recommend Marek. He is calm, reassuring, professional and patient. Thank you!Posted on Google JamesTrustindex verifies that the original source of the review is Google. Extremely happy and impressed. For context, I am a 21 year old male who contacted Marek due to acromioclavicular joint issues due to weightlifting. He was able to book me in a few days from my phone call with him. All my questions were answered in a detailed and informative manner, and the aftercare was great as he phoned me later in the day after reviewing my ultrasound images. The most important thing to note is his moral integrity which I was so surprised with due to how many people are today. Because of my issue I thought I would need a joint injection, however he said for my case this would be unnecessary and potentially delay healing. This is surprising as many practitioners these days would advise having the injection merely to make a buck off of me. I really respect this honesty and truthfulness. Thanks very much.Posted on Google Ruth CliffordTrustindex verifies that the original source of the review is Google. Thank you Marek! A comprehensive scan and explanation of my ankle issue with advice for self recovery and exercises moving forward. Most helpful. I would have no hesitation in recommending your service to others. Quick and easy to book an appointment online.Posted on Google Matt WebsterTrustindex verifies that the original source of the review is Google. Excellent experience with Marek at Physio-Soton. I came in with a long-running Achilles problem and he took a proper history, reviewed my training, tested the tendon thoroughly with Ultrasound — diagnosis, imaging and a clear rehab advice all in one visit. He was honest about what the findings meant for my running rather than telling me what I wanted to hear, and explained everything in plain terms. As a triathlete it's rare to find a physio who is also an MSK sonographer and genuinely understands training load. Highly recommended.Posted on Google Charlette MitchellTrustindex verifies that the original source of the review is Google. I had an excellent experience with Marek following my car accident. From the initial phone call through to my appointment at the clinic, he was professional, well spoken, and took the time to explain everything clearly, which immediately put me at ease. He carried out a detailed ultrasound scan of my shoulder, and having access to advanced diagnostic equipment within the clinic meant the assessment was thorough and precise. He clearly explained the findings, what they meant, and the treatment options available, giving me a much better understanding of my injury. Marek is highly experienced, exceptionally knowledgeable, and genuinely focused on providing the best care for his patients. His professionalism, expertise, and attention to detail were outstanding. I would highly recommend Marek to anyone looking for an accurate diagnosis and first-class treatment.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.

One clinician, start to finish: the person who assesses you, scans you and performs your injection is the same HCPC-registered specialist. No hand-offs, no repeating your story.
Ultrasound guidance isn’t optional here; it’s the method. Arthrosamid can only be delivered accurately as an ultrasound-guided procedure, and our clinic is built around musculoskeletal ultrasound.
All-in pricing below typical hospital rates: £2,600 including consultation, imaging and the procedure, where UK hospital prices often start above £3,000 with consultation and scans charged separately.
Candidacy honestly assessed first: Arthrosamid is not right for every knee, and we will tell you if it isn’t yours. The £60 consultation carries no obligation.
Rehabilitation under the same roof: recovery matters as much as the injection, and our physiotherapy team handles your aftercare in the same clinic.

⭐⭐⭐⭐⭐ Patient Review
Thank you Marek
Can I say how impressed I was with you as a person, your equipment and the way you carried out the procedure.
My previous experience was at a private hospital and with you it was significantly better
All good wishes Jack

Arthrosamid is an injectable hydrogel implant, a soft, water-based polyacrylamide gel (iPAAG) that integrates with the synovium, the tissue lining your knee joint capsule. Rather than wearing off like a drug, the hydrogel stays in the joint, cushioning it and calming the inflamed synovium that drives much of the pain in knee osteoarthritis. It’s a single, one-step procedure performed under local anaesthetic, so you’re in and out of the clinic the same day. Arthrosamid has been used to treat more than 15,000 patients across 200+ clinics in Europe.
It works on a different mechanism entirely. A cortisone injection suppresses inflammation and typically lasts weeks to a few months. Hyaluronic acid supplements the joint fluid and tends to last longer than steroids. Arthrosamid is an implant, not a temporary medication it acts on the synovium itself and is designed to provide relief for many months and often years from a single treatment. That’s also why it takes longer to reach full effect.
At Physio Soton, the complete Arthrosamid treatment costs £2,600. That covers your professional knee assessment, diagnostic ultrasound scan, the Arthrosamid product, and the ultrasound-guided procedure itself. Physiotherapy and rehabilitation afterwards are priced separately and can be arranged in our clinic.
For context: private Arthrosamid prices across the UK typically range from around £2,000 to £3,500 per knee, and hospital packages often start above £3,000, frequently with consultation fees and diagnostic scans charged on top. Our price is all-in, so there are no surprises. You can compare all our treatment options on the full injection price list.
Arthrosamid is not currently available on the NHS, so private treatment is the route for UK patients.
Not every knee is a good candidate, and honest selection is what makes this treatment succeed. From clinical experience and the published evidence, the patients who tend to respond best are those with:
That’s why the pathway always starts with an examination and a diagnostic ultrasound scan, sometimes further investigations too, before this treatment is offered. If your knee is more likely to respond to a different option, from physiotherapy to a knee injection of another type, that’s what we’ll recommend instead.
Arthrosamid takes up to 12 weeks to deliver its full benefit. It is a slower-building treatment than a steroid injection, and expecting instant results is the most common misunderstanding.
Once established, the hydrogel remains in the joint, and published follow-up studies have shown sustained pain relief and improved function for many patients, extending for years. Your clinician will give you realistic expectations for your knee at the consultation, not a sales pitch.
Arthrosamid has a strong safety record. A 2022 systematic review of intra-articular polyacrylamide hydrogel (Cole et al.) found the treatment safe, with no long-lasting adverse events reported. Short-term effects: some pain or swelling in the days after injection are common and settle as the knee adjusts.
Because Arthrosamid is an implant, not just an injection, we take infection prevention seriously: you’ll take a single prescribed antibiotic dose before treatment, and the procedure is performed in sterile conditions under real-time imaging. Our approach to knee osteoarthritis follows the principles of the NICE osteoarthritis guideline (NG226), treatment only where clinically appropriate, alongside exercise and rehabilitation.
The first 48 hours: walking only, with your activity significantly reduced. The first two weeks: very gentle use of the knee; take it genuinely easy, and don’t rush back to sport or running. From there, a structured return to activity with physiotherapy support gives the hydrogel the best environment to do its work. Most patients need no time off desk-based work.
Your Arthrosamid injection is performed by Marek Czeladzki — Senior Chartered Physiotherapist, musculoskeletal sonographer and independent prescriber (HCPC and CSP registered; member of the British Medical Ultrasound Society and the American Institute of Ultrasound in Medicine, with ultrasound-guided injection training completed at the University of Essex and advanced cadaveric training at King’s College London).
Arthrosamid can only be administered by appropriately trained clinicians under ultrasound guidance at Physio Soton; the clinician holding the probe is the same one who assessed your knee.
Yes, one simple step. We prescribe a single-dose antibiotic to take before treatment. Although Arthrosamid is given as an injection, it is also an implant, and the antibiotic is important to reduce the already-low risk of infection.
No. Arthrosamid is currently a private treatment in the UK, which is why transparent pricing matters. Our £2,600 covers the complete process at our Eastleigh clinic.
Gradually, full benefit takes up to 12 weeks. This is a completely different pattern from a steroid injection, which acts within days but fades within months.
Yes, it works best as part of a plan. We routinely combine it with physiotherapy and structured exercise after the recovery window, and your consultation will map out the right sequence for your knee.
If knee osteoarthritis is deciding what you can and can’t do, find out whether an Arthrosamid injection is right for you honestly assessed, clearly priced, and performed by the clinician who scans you.
