Ultrasound-Guided Scraping for Chronic Patellar Tendinopathy: A Case Presentation

Chronic patellar tendinopathy is a common complaint among athletes who repetitively stress the extensor mechanism of the knee. Multiple treatment options have been described, but evidence is lacking, specifically when eccentric loading has failed. Debate continues regarding the patho-etiology of chronic patellar tendon pain. There has been recent interest regarding the neurogenic influences involved in chronic tendinopathy, and interventions targeting neovessels and accompanying neonerves have shown promise. This is the first description of an ultrasound-guided technique in which the neovessels and accompanying neonerves in patellar tendinopathy were targeted using a needle scraping technique of the posterior surface of the patellar tendon.
