This surgery is performed for patients whose joint contracture does not improve with conservative treatment (such as physical therapy) and whose range of motion limitations interfere with daily life. It is typically indicated in cases of severe contracture, especially in patients with a history of trauma or coexisting diabetes.
 

Figure 1 is an anatomical illustration of the glenoid, along with the ligaments and labrum attached to it.
 
 

As shown in Figure 2, during the surgery, the capsule at the edge of the labrum is released arthroscopically. Releasing the anterior and inferior portions of the joint capsule improves the range of motion. However, postoperative rehabilitation is essential to maintain and enhance these improvements.
