Leech Me Alone! Atraumatic Hemarthrosis after Hirudotherapy
Case report published in Cureus (2020)
Abstract
A 58-year-old male presented to the emergency department with a chief complaint of knee pain and swelling after performing hirudotherapy (leech therapy) approximately one week prior. Knee arthrocentesis demonstrated significant hemarthrosis. Hirudotherapy is being used for a broad array of reasons including treatment of osteoarthritis, to plastic and reconstructive surgery. Case reports and journal articles often discuss cutaneous reactions, bleeding, and infection as common adverse events. Intra-articular bleeding is not commonly mentioned. With hirudotherapy being utilized more as alternative therapy for osteoarthritis and joint pain, physicians should be aware of hemarthrosis as a possible adverse reaction.

Summary
A 58-year-old male presented to the emergency department with a chief complaint of knee pain and swelling after performing hirudotherapy (leech therapy) approximately one week prior.
Why This Matters for Hirudotherapy
This case report describes a 58-year-old male who presented with knee pain and swelling approximately one week after performing hirudotherapy, with arthrocentesis revealing significant hemarthrosis. The observation is directly relevant to the clinical practice of hirudotherapy—particularly its use as an alternative therapy for osteoarthritis—by identifying intra-articular bleeding as a potential adverse reaction. While existing literature often focuses on cutaneous reactions, localized bleeding, and infection, this case highlights the need for physicians to recognize deeper joint bleeding as a possible complication. However, because this is a single case report, it cannot establish the true incidence or prevalence of hemarthrosis following leech applications, nor does it provide mechanistic insights into how the leech salivary secretome might induce this specific complication.
