Arthroscopy and Manipulation vs a Home Therapy Program in the Treatment of Adhesive Capsulitis

The purpose of this study is to compare two treatments used for treating frozen shoulder which are arthroscopy and forceful stretching of the shoulder and home stretching therapy to see if one relives pain and improves shoulder motion more quickly. The other purpose is to try and understand what causes frozen shoulder. For this purpose, tissue will be taken from the shoulder during surgery and studied for the presence and level of a protein called cytokine (Connective Tissue Growth Factor)
