When it may be considered
- Selected cases of mild or moderate osteoarthritis.
- Patellar tendinopathy when indicated.
- Focal injuries within a comprehensive treatment plan.
Your recovery, step by step
A medical assessment helps establish how PRP may benefit you and integrate it into a treatment and rehabilitation plan tailored to your needs. The aim is to improve your symptoms and your ability to take part in the activities that matter to you, while monitoring your progress.
Osteoarthritis is not the same as a meniscal tear
A painful knee needs a diagnosis before choosing an injection. Intra-articular PRP does not repair a torn ligament on its own and is not equivalent to meniscal repair.
Evidence and expectations in osteoarthritis
The knee is one of the most extensively studied sites. Some sources describe symptomatic improvement, while NICE highlights limitations in the quality of the evidence. Uncertainty and alternatives must be explained; it should not be offered as a way of rebuilding cartilage.
How to assess whether it has helped
It is helpful to record pain and activity limitations before treatment and compare them at follow-up. Therapeutic exercise, strengthening and load management remain part of the approach.
