From the Research
After arthroscopic capsular release for frozen shoulder, scar tissue can begin forming within days, with significant reformation potentially occurring within 6-12 weeks if proper rehabilitation is not followed. This is why immediate and consistent physical therapy is crucial following surgery, typically starting within 24-48 hours post-procedure 1. The rehabilitation protocol usually involves daily passive and active range of motion exercises for at least 6-8 weeks to maintain the mobility gained during surgery. Patients may be prescribed NSAIDs like ibuprofen (400-600mg three times daily) to manage inflammation and pain during this period. A home exercise program is essential and should be performed 3-5 times daily as instructed by a physical therapist.
Some key points to consider in the rehabilitation process include:
- The importance of early mobilization to prevent scar tissue formation and adhesion 2
- The use of continuous passive motion machines in the early recovery phase to maintain range of motion
- The biological process of scar formation, which involves initial inflammation followed by fibroblast proliferation and collagen deposition, leading to adhesions if movement is restricted 3
- The recommendation by most surgeons to maintain full range of motion for at least 3 months post-surgery to minimize the risk of recurrent stiffness from scar tissue reformation 4
Overall, the goal of rehabilitation after arthroscopic capsular release for frozen shoulder is to prevent scar tissue reformation, maintain range of motion, and restore functional ability, with the most recent and highest quality study 1 supporting the importance of early and consistent physical therapy in achieving these outcomes.
