Sven Putnis offers advanced knee injections in Bristol, including steroid, Durolane (hyaluronic acid), and Arthrosamid hydrogel for lasting osteoarthritis relief.
For patients experiencing debilitating knee osteoarthritis, delaying a joint replacement for as long as clinically appropriate is highly recommended. To facilitate this delay and improve daily function, Sven Putnis offers a highly selective, evidence-based range of injectable treatments. These include short-term steroid injections for breakthrough pain, Durolane (hyaluronic acid) for medium-term lubrication, and the innovative Arthrosamid hydrogel—a permanent injectable implant that acts as a barrier layer within the synovial lining of the knee.
Who Is This For?
A steroid injection typically provides rapid pain relief that lasts anywhere from a few weeks to a few months. Because repeated steroid use can damage cartilage, it is best used as a single injection to then allow you to complete necessary bracing or physiotherapy exercises.
Durolane is a hyaluronic acid injection that temporarily lubricates the joint and typically provides relief for about six months before being absorbed by the body. Arthrosamid is a non-biodegradable hydrogel that permanently integrates into the joint lining, acting as a long-lasting physical barrier against inflammation.
Yes. Arthrosamid is highly biocompatible and has been extensively tested in clinical trials. It is licensed in the UK as an injectable implant and has demonstrated an excellent safety profile with very few adverse effects reported in long-term studies 3.
No injection can cure osteoarthritis or regrow lost cartilage. The primary goal of these injections is to significantly reduce or eliminate pain, improve your mobility, and delay the need for a knee replacement for as long as possible.
The injection is performed by Sven Putnis, under ultrasound guidance, in a clinical setting. He uses local anaesthetic to numb the area first to minimise discomfort and reassures you throughout. You may experience a sensation of fullness or mild swelling in the knee for a few days following the procedure, which is a normal part of the hydrogel integrating into the joint lining.
