Sonography and Haemophilia

University Hospital, Bonn5 enrolled

Overview

The aim of this study is to evaluate the possibility of establishing a patient-based ultrasound monitoring of the knee (representing a target joint accessible with any hand) with a handheld device: The following questions will be answered: 1. What is necessary for the organisational implementation of a patient-based ultrasound monitoring in patients with haemophilia? 2. Is it possible to train patients with haemophilia to perform sonography of their target joints? 3. Does a patient-based ultrasound monitoring with a handheld device work in a home setting? 4. What is the quality of the patient's self-acquired ultrasound images? 5. Will the test persons be able to distinguish normal findings from (any) pathologic findings?

Time frame: 5 min

Landmarks of the Hemophilia Early Arthropathy Detection with Ultrasound (HEAD-US) protocol - Anterolateral transverse ultrasound image

The patients will perform an ultrasound of their left and right knee according to the HEAD-US protocol. The following ultrasonic image is needed: Anterolateral transverse ultrasound image. Patellofemoral joint, lateral parapatellar recess, lateral patellar retinaculum and lateral femoral condyle must be visible.

Time frame: 5 min
