Introduction
Achilles tendinopathy [AT] is a functional problem characterised by swelling and pain above the Achilles tendon insertion region. In individuals with AT, PRP or platelet-rich plasma can be used as an alternative modality of treatment with an aim to lessen the discomfort and enhance functional recovery. We assessed the available data supporting the effectiveness of PRP in treating chronic AT.
Materials and methods
We did a literature search for randomised controlled trials [RCTs] that contrasted the effectiveness of PRP with that of eccentric exercise and placebo injections as treatment for AT in databases such as the Cochrane Library, Web of Science, PubMed, and EMBASE. The Visual analogue scale [VAS] score, Victorian Institute of Sports Assessment-Achilles [VISA-A] score, and Achilles tendon thickness were used to measure the results. We used the RevMan 5.3.5 software for statistical analysis.
Results
We included five RCTs in this meta-analysis. There was no significant difference in the VISA-A between the PRP and placebo groups at 12 weeks, 24 weeks and 1 year after treatment. However, at 6 weeks after treatment, PRP exhibited better efficacy than the placebo treatment. Two studies in our meta-analysis included VAS scores and tendon thickness. There was no significant difference in VAS scores at 6 weeks and 24 weeks after treatment. However, VAS scores at 12 weeks and tendon thickness were significantly different.
Conclusion
PRP injection is an effective treatment for chronic AT. It has a unique potential for increasing function and reducing discomfort in AT patients.
