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.

Enrollment
50
5 ml blind intra-articular corticosteroid injection
15 ml intra-articular injection to shoulder via anterior approach under ultrasound guidance
Change from baseline pain score on Visual Analog Scale(VAS)
Pain scored according to VAS; between 0(no pain) to 10(worst pain)
Time frame: Baseline, 1 week, 1 month, 3 months
Change in Shoulder Pain and Disability Index(SPADI) scores
Scored between 0-10 ; 0 means no pain and disability and 10 means the worst pain and disability
Time frame: Baseline, 1 month, 3 months
Change in Range of Movement(ROM)
Range of shoulder movements assessed with digital inclinometer in sittting and lying positions
Time frame: Baseline, 1 week, 1 month, 3 months
Ultrasound Parameters
Coracohumeral ligament(CHL) thickness, axillary pouch(AP) thickness, elastography of deltoid muscle(anterior, middle, and posterior)
Time frame: Baseline, 1 month, 3 months
Proprioception(Active position sense- joint position error)
Shoulder joint is positioned in 30 degree flexion and 15 degree internal and external rotation in lying position, patient is asked to position their joints and errors in degrees noted
Time frame: Baseline, 3 months
Shoulder Strength
Measured with cybex isokinetic dinamometer, shoulder flexion/extension and shoulder internal/external rotation
Time frame: Baseline, 3 months
Changes in Depression Score
measured by Beck's Depression Inventory(between 0 to 40), 0 means no depression and 40 means severe depression
Time frame: Baseline, 1 months, 3 months
Changes in Life Quality Score
Items from the SF-36 (Short Form 36) survey, between 0(worst) to 100(best)
Time frame: Baseline, 1 month, 3 months
Treatment Satisfaction
Global Improvement and Satisfaction Score, between 1 to 5, 1 very dissatisfied, and 5 very satisfied
Time frame: 3 months
