If your symptoms are not relieved by therapy and anti-inflammatory medicines, you and your doctor may discuss surgery. It is important to talk with your doctor about your potential for recovery continuing with simple treatments, and the risks involved with surgery. The goal of surgery for frozen shoulder is to stretch and release the stiffened joint capsule.
The most common methods include manipulation under anesthesia and shoulder arthroscopy.
Manipulation under anesthesia. During this procedure, you are put to sleep. Your doctor will force your shoulder to move which causes the capsule and scar tissue to stretch or tear. This releases the tightening and increases range of motion.
Shoulder arthroscopy. In this procedure, your doctor will cut through tight portions of the joint capsule. This is done using pencil-sized instruments inserted through small incisions around your shoulder. In many cases, manipulation and arthroscopy are used in combination to obtain maximum results.
Most patients have very good outcomes with these procedures.
