biostudies-literatureUnknown14(2)Rosales JThe myotendinous junction is a highly specialized and complex structure between muscle and tendon. In recent years, various procedures have directly targeted the tendon, with corticosteroid, platelet-rich plasma, or biological therapy infiltrations being prominent. However, these interventions are painful, corticosteroids have demonstrated tendon damage, and anesthesia negatively impacts tenocyte proliferation and viability when used with platelet-rich plasma in the same injection site. There is a need to adapt the injection site to improve therapy effectiveness and pain tolerance. This article presents a proposal for an ultrasound-guided anesthetic block procedure in the myotendinous junction.Arthroscopy techniques103195https://www.ebi.ac.uk/biostudies/studies/S-EPMC11873477biostudies-literatureMyotendinous Junction Anesthesia: An Alternative Infiltration Site for Ultrasound-Guided Injections.PMC11873477Molina CDroppelmann GRosales JSaravia AGarcia NJorquera CfalseMyotendinous Junction Anesthesia: An Alternative Infiltration Site for Ultrasound-Guided Injections.The myotendinous junction is a highly specialized and complex structure between muscle and tendon.
