The Effects of Two Different Treatment Protocols on Shoulder Function, Quality of Life, and Ultrasound Parameters in Patients With Frozen Shoulder

The goal of this interventional study is to compare the outcomes of two different injection aprroaches in patients with frozen shoulder. The main questions it aims to answer are: * Is hydrodilatation better than intraarticular corticosteroid injection? * Is there any prognostic factors that will help clinicians guide their decision making when choosing between these two treatments? Participans will receive an injection(cortcosteroid and local anesthetics alone or with hydrodilatation-corticosteroid and local anesthetics plus sterile saline solution) and then they will follow a rehabilitation program.
