What is Arthrosamid?
Arthrosamid is an innovative injectable treatment for knee osteoarthritis. It consists of a non-biodegradable hydrogel, composed of 97.5% sterile water and 2.5% cross-linked polyacrylamide. When injected into the knee joint, it integrates with the synovial membrane (the lining of the joint capsule) and thickens the synovial fluid, providing cushioning, lubrication, and reducing inflammation. Unlike some other injectables, Arthrosamid is designed not to degrade in the body, offering a potentially longer-lasting effect.
Benefits of Arthrosamid Injections
Patients in the UK considering this treatment can expect several key benefits:
- Sustained Pain Reduction: Clinical trials have shown significant and long-lasting reductions in knee pain, with many patients experiencing relief for up to three years or more after a single injection.
- Improved Joint Function and Mobility: By cushioning and lubricating the joint, Arthrosamid helps to reduce stiffness and improve the range of motion, making daily activities more comfortable.
- Minimally Invasive: The procedure is a simple, one-step outpatient treatment, administered under local anaesthesia, avoiding the need for surgery.
- Potential to Delay or Avoid Surgery: For many individuals, Arthrosamid can provide an effective alternative to knee replacement surgery, or at least delay its necessity.
- Good Safety Profile: The hydrogel technology has been used safely for various indications for over 20 years, with clinical trials reporting no serious side effects specific to the hydrogel.
- Single Injection Treatment: Unlike some other injectable treatments that require multiple doses, Arthrosamid typically involves a single injection for prolonged relief.
Who is a Suitable Candidate?
Arthrosamid is approved for the symptomatic treatment of knee osteoarthritis. It may be a suitable option for individuals with mild to moderate knee osteoarthritis who have not found sufficient relief from conventional treatments such as painkillers, lifestyle modifications, or physiotherapy. It can also be a good choice for younger patients looking to delay knee replacement surgery or for those who are unable to undergo surgery. A specialist consultation is crucial to determine individual suitability.
The Injection Procedure
The Arthrosamid injection is a straightforward outpatient procedure, often performed with ultrasound guidance to ensure precise placement. Here's a general overview of what to expect:
- Preparation: The knee area will be thoroughly cleaned to ensure a sterile environment. You may also be given an oral antibiotic to minimise the risk of infection.
- Local Anaesthesia: A local anaesthetic will be applied to numb the area around the knee, minimising discomfort during the injection.
- Injection: The hydrogel is carefully injected into the synovial cavity of the knee joint. Ultrasound guidance may be used for accuracy.
- Post-Injection: The needle is removed, and a plaster is placed over the injection site. You may be allowed to leave the clinic shortly after the procedure.
Recovery and Aftercare
Recovery from an Arthrosamid injection is generally quick, with minimal downtime:
- Immediate Aftercare: You may feel some mild discomfort, pain, or swelling at the injection site as the anaesthetic wears off, which typically resolves within a few days to weeks. Continue with your usual painkillers as needed.
- Activity Restrictions: It is generally recommended to rest for approximately 72 hours after the injection and avoid strenuous activities like jogging or long walks for the first few weeks.
- Return to Activity: Most patients can return to their normal daily activities shortly after the procedure.
- Onset of Benefits: While some may notice improvement within 24 hours, the full benefits typically become apparent within four to twelve weeks as the hydrogel integrates with the joint tissues. Structured rehabilitation with a physiotherapist can aid recovery and optimize results.
Cost of Arthrosamid Injections in the UK
The cost of Arthrosamid injections in the UK can vary between clinics and typically ranges from approximately £2,150 to over £2,900 for a single knee. For both knees, the cost can range from around £3,995 to over £5,600. These prices generally include the hydrogel itself, the consultant's fee for the procedure, and sometimes follow-up appointments. It's important to confirm all inclusions with the clinic as initial consultation and diagnostic fees may be separate. Currently, private medical insurance may not cover this treatment, so it is advisable to check with your provider.
Clinical Evidence and Research
Arthrosamid has undergone extensive clinical trials and research, demonstrating its safety and efficacy. Studies have shown significant and sustained improvements in pain reduction and joint function, with benefits lasting beyond two years in many patients. Ongoing studies are monitoring patients for even longer durations to further establish the long-term effects of this innovative treatment.
In conclusion, Arthrosamid offers a compelling non-surgical option for individuals in the UK suffering from knee osteoarthritis, providing long-lasting pain relief and improved quality of life. As with any medical procedure, a thorough consultation with a qualified specialist is essential to determine if this treatment is the right choice for your individual circumstances.
