Arterial embolization found effective for recurrent hemarthrosis following knee arthroplasty
Patients with recurrent hemarthrosis after knee arthroplasty were effectively and safely treated with selective geniculate arterial embolization, according to results of this study.
Researchers retrospectively reviewed data for13 patients who experienced spontaneous recurrent hemarthrosis after knee arthroplasty. All patients were treated with arterial embolization, according to researchers.
Results showed an average interval of 47 months between arthroplasty and embolization, and an average time of 4.1 months from onset of hemarthrosis to embolization. Researchers noted resolution of hemarthrosis through embolization in 92.3% of patients. One clinical failure occurred, which researchers noted may have been a case of misdiagnosed perioperative joint infection. Researchers also found two patients with “transient cutaneous ischemia related to distal particulate embolization that resolved spontaneously.” – by Casey Tingle
