How do I choose between PRP, steroid, and gel injections for my knee?

✓ Accepted answer

The right knee injection depends on your arthritis stage, how fast you need pain relief, and whether you are paying out of pocket, as no single option is universally superior for all patients.

• Cortisone: Choose this if you need immediate relief. It reduces inflammation fast, with results often starting within days. However, it only lasts one to six weeks. The American Academy of Orthopaedic Surgeons supports it for short-term symptomatic relief, but repeated doses may weaken cartilage or tendons.
• Hyaluronic Acid (Gel): This is the strongest option for durability and safety. It aims for six to twelve months of relief by restoring joint lubrication. It has no cartilage damage risk and is typically covered by Medicare Part B in the US. There are over 12 FDA-approved formulations, so your doctor will match the molecular weight to your specific condition.
• PRP: Platelet-rich plasma offers the best long-term functional outcomes, lasting six to 18 months. However, it is generally not covered by insurance, costing between $500 and $2,000 out of pocket. It is the newest option, showing encouraging pooled results in recent meta-analyses involving over 3,300 patients.
• Goals: If you are actively delaying knee replacement surgery, PRP may be worth the cost. If you are a Medicare beneficiary looking for a cost-effective, safer long-term solution, hyaluronic acid is often the pragmatic choice. Cortisone is best reserved for acute flare-ups.

Warning: If your knee becomes suddenly red, hot to the touch, or severely swollen after an injection, contact your doctor immediately, as this can indicate a joint infection.
