Patellar tendinopathy is commonly encountered in orthopedic and sports medicine clinics. Ultrasound-guided (USG) percutaneous tendon scraping is well described for Achilles tendinopathy, but not patellar tendinopathy. This manuscript describes the technique and reports results from a case series of patients with patellar tendinopathy treated with USG percutaneous tendon scraping. A retrospective review of the medical record identified 6 patients who underwent tendon scraping for patellar tendinopathy. This was a retrospective case series performed by searching the medical record for patients who underwent tendon scraping for patellar tendinopathy. Six patients met the criteria for inclusion. Five had primary patellar tendinopathy and 1 had continued pain despite open debridement. There were 3 competitive athletes and 3 recreational athletes. No major adverse events were reported. All competitive athletes safely returned to the sport at 1 month. At an average follow-up of 13.5 6 months, mean improvement in the Victorian Institute of Sport Assessment-Patellar Tendon (VISA-P) score was 53 24.2 points. At the final follow-up, 83% of patients experienced a clinically significant improvement in symptoms. USG percutaneous patellar tendon scraping is a minimally invasive intervention that may improve symptoms and help patients safely return to sport/activity. Because the intervention is entirely outside of the tendon, it is low risk and may be useful for in-season athletes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
