Knee Arthritis Injections
Knee arthritis can cause pain, stiffness and difficulty with everyday activities. While injections do not cure arthritis, they can help reduce pain, improve movement and delay surgery for some people.
Below explains the main injection treatments available, what they do and what you can realistically expect.
Knee injection options
| Treatment | Duration | Evidence strength | Notes |
| Corticosteroids | Approximately 2–12 weeks | Moderate short-term evidence, limited long-term benefit | Best for acute flare-ups; repeated use may risk cartilage health |
| PRP | 6–12 months or longer | Growing evidence with variable outcomes | Best for mild to moderate osteoarthritis; insurance coverage often lacking |
| Hyaluronic acid | Weeks to months | Mixed evidence with modest benefit | May help selected patients; less effective in severe arthritis |
| Arthrosamid® | Months to years | Emerging evidence | Early studies suggest longer-lasting pain relief |
