Does PRP injection treat knee osteoarthritis?

Knee osteoarthritis changes joint surfaces and surrounding tissues, causing variable pain, stiffness, swelling, and reduced walking tolerance. PRP is prepared from your blood and injected near the joint; it aims to influence the local environment, not replace damaged cartilage.

Suitability depends on examination findings, joint changes, alignment, activity goals, health conditions, and previous treatments. Exercise therapy, activity planning, medicines, braces, or other options may also be discussed.

Arrange an assessment linking your symptoms with examination findings and, when useful, imaging. Physiotherapy can build thigh and hip strength, improve movement, and adjust activities that flare pain. Regular comfortable movement is often more useful than prolonged rest.

Ask what response is realistic, how progress will be reviewed, how rehabilitation continues, and whether medicines or health conditions affect suitability. Report infection, blood disorders, recent procedures, or medicines affecting clotting.

Seek urgent assessment for a hot, very swollen knee with fever, inability to bear weight, major injury, or a locked or deformed joint. After injection, worsening redness, drainage, fever, or severe escalating pain needs prompt review.

How advanced are my joint changes? What is PRP intended to achieve? Which exercise plan should I follow? What alternatives could help if symptoms continue?
