An update to the use of PRP in the treatment of Achilles Tendinopathy
In an update to our recent post regarding the use of PRP for Achilles Tendinopathy, a retrospective analysis of 26 patients was published this past month in Foot and Ankle Specialist (Oloff et al 2015). One of the authors has used PRP to treat Achilles Tendinopathy for both those patients who have needed surgery and for those treated non-operatively for the condition. Outcomes were based on the validated Victorian Institute of Sports Assessment-Achilles (VISA-A) questionnaire and evaluation of pre and post treatment MRI images. There was a statistically significant degree of improvement seen on pre and post MRI images. Both groups (surgical and non-surgical) improved to a similar degree.
One criticism is that this is a level IV study (evidence based medicine) and is based on a case series. It adds to the current body of literature which has shown that PRP may be helpful for Achilles Tendinopathy. Certainly, data from larger well controlled clinical trials is needed to determine effectiveness of PRP therapy and to define more specific treatment protocols.
