How many PRP treatments do most patients need?
Most protocols involve one to three injections, commonly spaced two to six weeks apart, though this varies with the condition and the tissue being treated. Chronic tendinopathy often needs more than a single injection; some joint injections are done once and reassessed. Rather than committing to a fixed number in advance, the more useful approach is an initial injection followed by reassessment at six to twelve weeks, since that is when the response becomes readable.
Why a series is common
PRP is intended to prompt a repair response rather than deliver immediate relief, and for chronically damaged tissue a single stimulus is often not enough to shift it. Where a series is used, each injection is meant to build on the last.
That said, more is not automatically better. Additional injections into a joint that has shown no response at all after an adequate interval deserve a rethink rather than a repeat.
What changes the number
How long the problem has been present, which tissue is involved, the severity on imaging, your activity demands, and how you respond to the first injection. A partial rotator cuff tear and an early arthritic knee are not the same plan.
Preparation method matters too — protocols using more concentrated preparations sometimes use fewer injections.
How we decide when to stop
By reassessing function, not just pain, at a set interval after each injection. If you are improving steadily, completing the planned series usually makes sense. If there has been no meaningful change after an adequate trial, the right answer is usually a different approach rather than another injection — and we will tell you that.
