“…Some observations also support its use in a clinical environment to diminish pain and improve function (17,18). Moreover, some tests with patients suffering from various tendinopathies have demonstrated that HA injections can lead to better clinical results than with corticosteroid injections (19)(20)(21). We aimed to compare the effect of PRP versus HA injections after three months on patients who have a proximal patellar tendinopathy.…”

Background. As patellar tendinopathies are frequently chronic there has been plenty of research carried out to develop effective treatments, among which platelet-rich plasma (PRP) and hyaluronic acid (HA). Hypothesis. Therefore we aimed to compare the effect after three months following injections of PRP compared with HA injections on patients with a proximal patellar tendinopathy. Methods. 33 sportsmen with chronic proximal patellar tendinopathies were included and randomised into 2 groups and treated respectively with PRP (obtained using an apheresis machine) or HA injections. To assess the evolution of the pathology, algo-functional tests (VISA-P and IKDC) and isokinetic tests were carried out pre-injection, after 6 weeks and after 3 months post-injections. Results. The results of VAS, algometric scores, IKDC scores and VISA-P showed a considerable improvement in the two groups over time (p<0.01), except for the US findings. Isokinetic tests showed significant modifications for the quadriceps in C60 (p=0.01) for the pathological limb only at the end of the follow-up period. VAS associated with isokinetic tests decreased significantly for all contraction modes after three months in the HA group (p<0.05). Correlations showed that there was a significant negative association between VAS and strength in C60, C240 and E30 (p<0.01) only for the PRP group. Conclusion. Both PRP and HA can alleviate the symptoms of proximal patellar tendinopathy in the medium term. However, only PRP leads to a decrease in pain associated with an increase in the strength of the quadriceps.
