A practical guide for proximal hamstring, adductor and selected sports tendon injuries, with emphasis on imaging and staged rehabilitation.
Which injuries are included?
This guide covers chronic proximal hamstring tendinopathy, selected partial hamstring injuries, adductor tendinopathy and related enthesis or tendon injuries. Acute high-grade muscle tears, avulsions and complete tendon ruptures are different injuries and may require urgent sports or orthopaedic assessment.
What does the evidence say?
The evidence for PRP in proximal hamstring and adductor tendon injuries is still developing, and the available studies should be interpreted in the context of substantial variation in injury type, PRP preparation and rehabilitation.
A systematic review identified only two randomised trials across proximal hamstring interventions and rated the overall evidence for injection therapies as low or very low certainty. One trial comparing PRP with autologous whole blood did not demonstrate a clear advantage for PRP.[15] Importantly, however, the study did not adequately characterise the total platelet dose delivered, which is now increasingly recognised as a potentially important determinant of PRP efficacy. A negative result from an incompletely characterised or relatively low-dose PRP preparation therefore cannot establish that appropriately dosed PRP is ineffective.
This is particularly relevant because “hamstring injury” is not a single biological condition. Acute musculotendinous tears, chronic proximal hamstring tendinopathy, enthesopathy, partial avulsion and intramuscular injury differ substantially in tissue biology, mechanical loading and healing requirements. Results from one subgroup should not automatically be applied to another.
There is also a reasonable biological rationale for PRP in tendon healing. Platelet-derived growth factors and signalling molecules are involved in cell recruitment, collagen synthesis, extracellular-matrix remodelling, angiogenesis and tissue repair. These mechanisms support continued investigation of PRP for chronic or incompletely healed tendon injuries, particularly where the abnormal tissue can be accurately identified and treated under image guidance.
The most appropriate interpretation is therefore that high-quality clinical evidence for hamstring and adductor PRP remains limited—not that PRP has been shown to be ineffective. Current studies have not adequately answered whether high-dose, biologically characterised and precisely targeted PRP, combined with an appropriate rehabilitation program, improves outcomes in carefully selected patients.
At MBR Health, PRP is considered selectively after the injury pattern has been defined with appropriate imaging. Rehabilitation and progressive loading remain central to recovery, while PRP may be considered as an adjunct in selected chronic or partial tendon injuries where the diagnosis, biological target and mechanical rehabilitation plan are clear.
Why MRI is useful in athletes
MRI can define the location, length and severity of a tear, identify tendon retraction, marrow injury and adjacent pathology, and help distinguish chronic tendinopathy from acute structural failure. Ultrasound is useful for dynamic assessment and image-guided treatment of accessible targets.
What is the role of image guidance?
Deep proximal hamstring and adductor targets sit near important nerves and vessels. Image guidance helps plan the route, localise the lesion and document the final needle position. The exact modality depends on anatomy and the treatment objective.
What should I expect after?
The early goal is to avoid provoking the treated tissue, not to prove that it feels better. Rehabilitation then progresses through range of motion, isometric work, strength, energy-storage loading, running and sport-specific change-of-direction work as appropriate. Timelines depend on the injury and sport.
Frequently Asked Questions
Can PRP get me back to sport faster?
There is not enough evidence to state that reliably. Some tendon conditions may benefit, but PRP has not been proven to shorten every muscle-injury recovery. A safe return depends on tissue healing, strength and function.
Do I need MRI before hamstring PRP?
For chronic proximal tendon pain or significant injury, MRI can be very useful to characterise the lesion and rule out an avulsion or other pathology.
Can PRP treat an avulsed tendon?
A complete or substantially retracted avulsion may require surgical review. PRP should not delay appropriate assessment.
Important: Acute loss of function, a palpable defect, significant bruising, suspected avulsion or progressive neurological symptoms require prompt assessment.
