This randomized clinical study was conducted on patients with disc displacement without reduction. Patient was selected one of the two study groups: control group received only arthrocentesis or test group received arthrocentesis + i-PRF. Arthrocentesis procedure was performed for all groups with two needle technique. For test group, intra-articular i-PRF was made. As a primary outcome variable, pain was recorded at preoperatively and at postoperatively 1, 2, 3, 6 and 12 months. Maximum mouth opening, lateral and protrusive movements were formed as secondary outcome variables.
