Nature of knee cartilage injuries
Knee cartilage injuries are a common cause of knee pain and discomfort, particularly in patients with osteoarthritis. Unlike bone and muscle tissues, cartilage lacks a direct blood supply, which significantly limits its ability to repair itself.
When the cartilage in the knee joint is damaged, it may lead to pain, swelling, inflammation, and reduced mobility. Over time, if left untreated, cartilage damage can progress and worsen, contributing to the development of osteoarthritis.
Common causes of knee cartilage injuries
Knee cartilage injuries often result from repetitive stress on the knee joint or traumatic events, including:
High-impact activities: Running, jumping, or heavy lifting can place stress on the knee joint, leading to cartilage wear and injury.
Previous knee injuries: Fractures, ligament tears, or meniscus damage can increase the risk of cartilage damage as the joint structure is altered.
Ageing: As we age, the cartilage naturally weakens and becomes more prone to damage due to wear and tear.
Obesity: Excess body weight can place increased pressure on the knee joints, accelerating cartilage degradation.
Genetic predisposition: Some individuals may be more susceptible to cartilage injuries due to their genetic makeup, making them more prone to joint problems.
Diagnosing knee cartilage injuries
Knee cartilage injuries often present with pain, swelling, and limited range of motion. Patients may also report clicking, locking, or catching sensations in the joint. Diagnosis typically begins with a physical exam to assess pain, tenderness, and mobility. Imaging tests like X-rays or MRIs are commonly used to visualise the joint, assess the extent of cartilage damage, and guide treatment planning.

Treatment overview
Arthrosamid® (a hydrogel) is an innovative treatment for knee osteoarthritis. It works by reducing inflammation around the joint, which is a key contributor to both knee pain and disease progression.
Arthrosamid is supported by more than two decades of research. It is proven to be safe and effective, offering long-lasting pain relief. The hydrogel is administered via a simple, one-step procedure under local anaesthetic. There is no need for complex surgeries, you can be in and out of our treatment centre on the same day.
MSK were the 1st to do in the UK have done over 500, have our own protocol for injection with good success rate and low complication rate. We have published and presented our results at international and nation conference.
About the product
Arthrosamid is a non-degradable and non-resorbable hydrogel composed of 2.5% cross-linked polyacrylamide and 97.5% non-pyrogenic water (McCollister et al., 1965). It is administered via an intra-articular injection into the knee joint.
The hydrogel serves as a scaffold for the synovial membrane, binding to the synovial membrane and acting as a physical buffer and scaffold.
Benefits
No long-lasting adverse effects have been reported in clinical studies
Positive effects have been shown to last for at least 2 years
Clinical studies have highlighted the efficiency of Arthrosamid, especially compared to traditional treatments like hyaluronic acid
