Frozen shoulder is painful, slow, and poorly understood by most patients — who often don't realize their shoulder has a predictable three-stage arc and that the majority improve without surgery if managed correctly. Dr. Graham gives non-operative treatment every reasonable chance before considering manipulation or capsular release.
Frozen shoulder can be primary (no identifiable cause) or secondary (following injury, surgery, or systemic disease). Both are treated here.
Understanding the Condition
Frozen shoulder — the clinical term is adhesive capsulitis — is a condition in which the joint capsule surrounding the glenohumeral joint becomes inflamed, thickened, and progressively scarred. The capsule, which normally allows the ball-and-socket joint to move freely through its full range, contracts and stiffens until even simple motions like reaching overhead or behind the back become impossible or severely painful.
The cause of primary frozen shoulder remains incompletely understood. It occurs most commonly in women between 40 and 60, often without a clear precipitating event. What is known is that inflammation drives the early stage, and fibrosis — the formation of dense scar tissue within the capsule — drives the later restriction.
Frozen shoulder is one of the most underdiagnosed and mismanaged shoulder conditions in general practice. Patients are often told to push through pain and stretch aggressively — which can be counterproductive in the inflammatory freezing stage — or told to simply wait it out without a clear treatment plan. Understanding the stage a patient is in changes everything about how they should be managed.
In frozen shoulder, the joint capsule thickens and contracts, reducing joint volume dramatically. The axillary pouch — the redundant fold of capsule that normally allows the arm to elevate — is obliterated by scar tissue.
The rotator cuff interval, between the supraspinatus and subscapularis, is often the site of earliest and most severe contracture. Arthroscopic release targets this region first.
Disease Progression
Understanding which stage a patient is in determines how they should be treated. The approach in Stage 1 is different from Stage 2 — and getting that wrong can slow recovery.
This is the most painful stage. The capsule is actively inflamed — synovitis is driving progressive stiffness, and the shoulder hurts both with movement and at rest. Night pain is often the most disruptive symptom.
Aggressive stretching in this stage can worsen inflammation and is counterproductive. The focus should be on pain management and preserving motion gently — not forcing range of motion against an actively inflamed capsule.
Pain often improves in this stage — sometimes dramatically — but motion remains severely restricted. The inflammation has subsided, but the capsule has been replaced by dense fibrous scar tissue that physically prevents movement.
This is the stage where physical therapy can be most effective, and where a well-timed corticosteroid injection into the glenohumeral joint creates the best environment for rehabilitation. Patients in Stage 2 often feel better than they look on examination — range of motion is far more restricted than the pain level suggests.
Motion gradually returns, often beginning with external rotation and elevation. The capsule softens and remodels spontaneously. Most patients recover full or near-full motion if they have not developed fixed contracture from prolonged disuse.
Not everyone reaches this stage without help. Patients who have not made meaningful progress after 6 months of appropriate non-operative treatment are candidates for intervention — rather than waiting out an unpredictable natural history that may extend for years.
Who Gets Frozen Shoulder
Primary frozen shoulder occurs without a clear cause. Secondary frozen shoulder follows a known trigger — and often requires a different clinical approach.
Diabetes is the strongest known risk factor for frozen shoulder. Patients with diabetes — particularly those with longstanding or poorly controlled blood sugar — develop frozen shoulder at rates up to five times higher than the general population. The contractures tend to be more severe, more resistant to conservative treatment, and more likely to be bilateral.
Corticosteroid injections can transiently raise blood glucose and require coordination with the patient's primary care physician or endocrinologist. Diabetic frozen shoulder patients often need intervention sooner and recover more slowly — setting realistic expectations at the first visit is essential.
Stiffness following rotator cuff repair, shoulder replacement, labral repair, or any other shoulder procedure is a recognized complication — and one of the more challenging forms of frozen shoulder to manage. The underlying surgery changes the anatomy, creates scar tissue of its own, and may limit what manipulation can safely achieve.
Post-surgical frozen shoulder more often requires arthroscopic capsular release rather than manipulation alone, and the timing of intervention must be coordinated with healing of the index repair. These patients are seen and managed as a distinct clinical entity.
Proximal humerus fractures — particularly those treated non-operatively with prolonged immobilization, or those complicated by malunion — commonly produce shoulder stiffness that can meet the clinical definition of frozen shoulder. The combination of injury-related inflammation and immobility drives rapid capsular contracture.
Managing post-fracture stiffness requires understanding the underlying bony anatomy before manipulation is considered. In cases where malunion is contributing to restricted motion, the bony problem must be addressed before soft tissue release will be effective.
Treatment Pathway
A defined sequence — every step given a genuine chance to work before moving to the next. Most patients never need to reach Step 3.
A structured physical therapy program is the foundation of non-operative management. The approach changes based on stage. In the freezing phase, the focus is gentle range-of-motion preservation and pain control — not aggressive stretching that inflames an already irritated capsule. In the frozen phase, more active range-of-motion work, pendulum exercises, and stretching in a pain-free arc are appropriate.
Dr. Graham refers to therapists who understand this distinction. Patients who are prescribed aggressive stretching in Stage 1 often plateau earlier and feel defeated by a treatment that is worsening rather than helping their condition.
A corticosteroid injection into the glenohumeral joint reduces the inflammatory burden on the capsule and creates a pain window that allows more effective physical therapy. Dr. Graham typically performs one to two injections in appropriate patients — the first often early in the treatment course, the second if meaningful benefit was seen from the first but partial restriction remains.
In Dr. Graham's experience, injections work best as a bridge to rehabilitation, not as standalone treatment. An injection that provides temporary relief but is not followed by active therapy loses most of its benefit within weeks. The combination of injection plus therapy is meaningfully more effective than either alone.
After approximately six months of genuine non-operative management without acceptable progress, Dr. Graham considers manipulation under anesthesia. The patient is placed under general anesthesia combined with a regional nerve block. With the shoulder fully relaxed, Dr. Graham carefully and forcibly moves the shoulder through its full arc of motion — breaking up the adhesions that have restricted the capsule. The procedure itself takes only minutes.
The nerve block provides post-operative pain control and — critically — allows therapy to begin the very next day, while the shoulder is comfortable enough to move. In Dr. Graham's experience, aggressive physical therapy immediately after MUA is what preserves the motion gained during manipulation. Without it, the capsule tends to re-tighten.
Arthroscopic capsular release is used in several distinct situations. The most straightforward is secondary frozen shoulder following prior surgery or fracture, where scar tissue is more organized and less likely to yield to manipulation alone. It is also used when MRI or clinical findings suggest dense capsular contracture that would not release adequately with a closed manipulation.
A critically important additional indication is the patient with a known pre-existing rotator cuff tear or labral tear presenting with frozen shoulder. In these cases, Dr. Graham proceeds directly to arthroscopic capsular release rather than MUA — because placing forcible manipulative loads on a shoulder with an already compromised rotator cuff or labrum risks extending those injuries. The capsular release achieves the needed mobility without subjecting the damaged structures to undue stress.
It is equally important to understand what is not done at this surgery: evidence consistently shows that performing a rotator cuff repair, labral repair, or similar reconstructive procedure in the setting of active frozen shoulder produces inferior results. The concurrent stiffness creates a hostile healing environment and limits the rehabilitation that those repairs depend on. When a pre-existing tear is identified alongside frozen shoulder, the frozen shoulder is addressed first — the reconstruction follows once full motion is restored.
"Dr. Graham called me the evening of my surgery on his way home to check in. That's not something you expect from a surgeon."
