2.2. Intervention
ESWT and sham ESWT were administered by one physiatrist. A Dornier Aries system (Dornier MedTech Systems, GmbH, Germany) was used to deliver the shockwaves. Dornier Aries system uses flat electromagnetic shockwave emitter technique. In addition, it is composed of smart focus type providing a wide focal zone for surface and deep tissue treatment. Patients underwent three treatments at weekly intervals. For that, patients were positioned supine, with the treating knee flexed and one foot on the table.At each treatment session, the experimental group received 1000 shockwaves at 0.05 mJ/mm
