Ultimate Guide to Knee Cartilage Repair: Modern Biological Treatments Explained by MSK Doctors

knee cartilage plays a vital role in our joint health, acting as a cushion that allows for smooth and pain-free movement. However, cartilage damage is a common issue that can lead to significant pain and reduced mobility. At MSK Doctors, we aim to inform patients about the latest advancements in biological treatments for knee cartilage repair. This article is designed to answer your most pressing questions and provide valuable insights into how these treatments can improve your quality of life.

What is Knee Cartilage and Why is it Important?

Knee cartilage is a tough, flexible tissue that covers the ends of bones in your knee joint. It reduces friction, absorbs shock, and allows for smooth movement. There are two main types of cartilage in the knee: articular cartilage and meniscus cartilage. Articular cartilage covers the ends of bones, while the meniscus cartilage acts as a shock absorber between the thigh bone and shin bone.

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.

Biological Treatments for Knee Cartilage Repair

biological treatments have revolutionised the way we approach knee cartilage repair. These treatments utilise the body's natural healing processes to repair and regenerate damaged cartilage. Here are some of the most effective biological treatments available:

1. Platelet-Rich Plasma (PRP) Therapy: prp therapy involves extracting a small amount of your blood, processing it to concentrate the platelets, and injecting it into the damaged area. Platelets contain growth factors that promote healing and tissue regeneration. prp therapy is minimally invasive and can significantly reduce pain and improve joint function.

2. stem cell therapy: stem cell therapy uses the body’s own stem cells to repair damaged tissue. These cells can differentiate into various types of cells, including cartilage cells, promoting regeneration and repair. Stem cells are typically harvested from bone marrow or adipose tissue and injected into the affected area to enhance healing.

3. hyaluronic acid injections: Hyaluronic acid is a natural substance found in the synovial fluid of joints. Injections of hyaluronic acid can help lubricate the joint, reduce pain, and improve mobility. This treatment is particularly beneficial for patients with mild to moderate osteoarthritis.

4. autologous chondrocyte implantation (ACI): ACI involves taking a small sample of cartilage cells from your knee, growing them in a lab, and implanting them back into the damaged area. This procedure promotes the growth of new, healthy cartilage and is effective for treating larger cartilage defects.

How Biological Treatments Improve Knee Health

biological treatments offer several advantages over traditional surgical methods. They are less invasive, have fewer side effects, and promote natural healing processes. By addressing the root cause of cartilage damage, these treatments can provide long-term relief and improve joint function.

At MSK Doctors, we combine cutting-edge biological treatments with advanced surgical techniques to ensure the best possible outcomes for our patients. Our approach is patient-centred, focusing on individual needs and promoting overall musculoskeletal health.

FAQs about Knee Cartilage Repair and Biological Treatments

Q1: What is the recovery time for prp therapy? Recovery time for prp therapy varies but generally ranges from a few days to a couple of weeks. Most patients experience significant improvement within 4 to 6 weeks.

Q2: Are there any risks associated with stem cell therapy? stem cell therapy is generally safe, but potential risks include infection, bleeding, and allergic reactions. It’s essential to consult with a qualified specialist to understand the benefits and risks.

Q3: How effective are hyaluronic acid injections for knee pain? Hyaluronic acid injections can be highly effective for reducing knee pain and improving mobility, especially in patients with mild to moderate osteoarthritis. Results can last from several months to over a year.

Q4: What makes ACI different from other cartilage repair methods? ACI uses your own cartilage cells to repair damage, promoting natural cartilage growth. It’s particularly effective for larger defects and can provide long-term results compared to other methods.

Q5: Can biological treatments prevent the need for knee replacement surgery? In many cases, biological treatments can delay or prevent the need for knee replacement surgery by promoting natural healing and improving joint function. However, the effectiveness depends on the extent of cartilage damage.

Q6: How do I know if I’m a candidate for biological treatments? A thorough evaluation by an orthopaedic specialist is necessary to determine if you are a candidate for biological treatments. Factors such as the extent of cartilage damage, overall health, and treatment goals will be considered.
