The plasma administration procedure is preceded by a standard ultrasound examination in order to precisely locate the tendon areas within which we want to accelerate the healing and repair processes. After preparing the plasma obtained from the patient's blood, the doctor uses an ultrasound to mark the injection site. If necessary, he observes the position of the needle in real time so as to inject the plasma exactly into the changed site of the tendon. A small patch is put on the skin after the injection.
