Utterly unsurprising: injecting your own blood doesn’t help tendinitis. Nice to have a decent new trial about this over-hyped therapy though.
The administration of two unguided peritendinous autologous blood injections one month apart, in addition to a standardised eccentric training programme, provides no additional benefit in the treatment of mid-portion Achilles tendinopathy.
Not many good treatment ideas work as well in practice as they do in theory. The null hypothesis is super reliable.
