• Channel: Talking With Docs

Overview

This video discusses various types of injections used to treat knee arthritis, focusing on their effectiveness, duration of action, and potential drawbacks. The speakers explain cortisone injections, hyaluronic acid injections, and platelet-rich plasma (PRP) injections, while also addressing the current lack of evidence for stem cell therapies in treating knee osteoarthritis. The video aims to inform viewers about available options to manage knee pain and improve function.

Key takeaways

• Cortisone Injections: These are a common first-line treatment for arthritic knees, acting as a strong anti-inflammatory. They typically provide pain relief for 2-3 months and are not generally considered harmful to cartilage in the long run.
• Hyaluronic Acid Injections: These injections supplement the natural lubricant in the knee joint, aiming to reduce pain and improve function for 6-8 months. Combining them with corticosteroids may extend their effectiveness up to a year.
• Platelet-Rich Plasma (PRP) Injections: This treatment involves injecting concentrated platelets from the patient's own blood, which contain healing factors. While studies show varied results, PRP can last up to a year and may be combined with hyaluronic acid for enhanced effects. Leukocyte-poor PRP is recommended for knee osteoarthritis.
• Cell Therapy (Stem Cells): Currently, there is no scientific evidence to support the use of stem cells, fat cells, or bone marrow aspirates for treating knee osteoarthritis. Regulatory bodies like the FDA and Health Canada advise against promoting these therapies due to a lack of efficacy.
• Holistic Approach: Alongside injections, weight loss and exercise programs like the GLAD program are recommended for managing osteoarthritis and potentially slowing its progression.
