The Benefits of Bone Marrow Aspirate Concentrate (BMAC) Injections for Knee Health

London Cartilage Clinic

Knee cartilage is a crucial component of our joints, providing a smooth surface for bones to glide over each other and cushioning impact during movement. Damage to this vital tissue can lead to significant pain and reduced mobility. Bone Marrow Aspirate Concentrate (BMAC) injections are just one of the many specialised treatments on offer today to improve knee health. This article aims to answer your most pressing questions about BMAC injections and how they can help improve your long term knee health.

What is a BMAC Injection?

When cartilage is damaged due to injury or arthritis, it can lead to pain, swelling, and decreased mobility. Understanding the role of knee cartilage and the importance of keeping it healthy is the first step towards effective treatment and recovery. Bone Marrow Aspirate Concentrate (BMAC) injection is a regenerative treatment that uses your body's own stem cells and growth factors to promote healing and repair of damaged tissues. The process involves extracting a small amount of bone marrow, usually from the hip bone, concentrating the stem cells and growth factors, and injecting them into the damaged area of the knee. The creation of the injection follows this process:

  1. Bone Marrow Extraction: The procedure begins with the extraction of bone marrow from the patient’s hip bone. This is done using a needle under local anaesthesia, ensuring minimal discomfort.
  2. Concentration Process: Once the bone marrow is extracted, it is processed in a centrifuge to concentrate the stem cells and growth factors. This concentrate, known as Bone Marrow Aspirate Concentrate (BMAC), is rich in the elements needed to promote healing and tissue regeneration.
  3. Injection into the Knee: The BMAC is then injected into the damaged area of the knee. The stem cells and growth factors work together to promote the repair and regeneration of damaged cartilage, reducing pain and improving joint function.

How BMAC Injections Improve Knee Health

BMAC injections offer several advantages over traditional treatments for knee cartilage damage. They utilise the body’s natural healing processes, which can lead to more effective and long-lasting results. By addressing the root cause of cartilage damage, BMAC injections can provide significant relief and improve joint function. BMAC injections are commonly used to treat osteoarthritis, cartilage damage, tendon injuries, and other joint-related conditions. A qualified medical professional will help determine if you're a suitable candidate to receive this treatment.

Arthrosamid Treatment Benefits for Patellofemoral Osteoarthritis Kneecap Pain

Patellofemoral osteoarthritis (OA) targets the kneecap and thigh bone joint, causing pain during bending activities like stair climbing and cycling. Arthrosamid, an injectable polyacrylamide hydrogel, provides cushioning that reduces friction and alleviates pain by supplementing worn cartilage. Clinical studies demonstrate improved joint comfort and mobility post-injection, particularly for activities stressing the kneecap. Treatment success varies; therefore, expert assessment is critical for patient suitability. Led by cartilage expert Professor Paul Lee, the London Cartilage Clinic offers tailored Arthrosamid therapy combined with thorough evaluation and rehabilitation support. Patients commonly report reduced kneecap pain and enhanced function, improving daily life quality. While promising, Arthrosamid should be part of a personalized treatment plan overseen by specialists to achieve optimal outcomes in managing patellofemoral OA.
