Frozen shoulder, or adhesive capsulitis, is a condition in which the capsule, the envelope of tissue that surrounds the shoulder joint, becomes inflamed, thickened, and tight. As it contracts, it physically restricts the shoulder, causing pain and a progressive loss of motion in every direction, including when someone else tries to move the arm for you.
It is more common in people with diabetes and can follow a period of immobilization, such as after an injury or surgery when the arm is kept still. Frozen shoulder classically moves through three phases: a painful freezing phase, a stiff frozen phase, and a thawing phase as motion gradually returns. The reassuring fact is that the large majority of cases resolve over time, and treatment is aimed at controlling pain and speeding the return of motion.
The three phases
Frozen shoulder typically progresses through three overlapping stages:
- Freezing: increasing pain, often worse at night, with motion gradually becoming more limited
- Frozen: pain begins to ease, but stiffness dominates and the shoulder is at its most restricted
- Thawing: motion gradually returns over months as the capsule loosens
Symptoms
The hallmark is loss of motion in every direction, including passive motion when the examiner moves the arm. This global loss of motion is what distinguishes frozen shoulder from problems like a rotator cuff tear, where the patient is weak but can be moved through a fuller range passively.
Pain is prominent in the early freezing phase, often disturbing sleep, and tends to ease as the shoulder settles into the frozen phase.
How it is diagnosed
The diagnosis is primarily clinical, made by finding a global loss of both active and passive shoulder motion on examination. X-rays are typically normal and are used to rule out arthritis and other causes of a stiff shoulder.
An MRI is not required to diagnose frozen shoulder but is sometimes used to exclude other problems, such as a rotator cuff tear, when the picture is unclear. Risk factors such as diabetes are reviewed, since they influence the expected course.
Dr. Lee treats frozen shoulder non-surgically in the large majority of cases, because most shoulders recover their motion with time and the right program. The foundation is a structured physical therapy stretching program to restore motion, supported by anti-inflammatory measures, with patient reassurance that the condition is self-limited.
A corticosteroid injection is often used, particularly in the painful freezing phase, where it can reduce pain and shorten that phase. For the small number of refractory cases that do not regain motion, Dr. Lee discusses manipulation under anesthesia or arthroscopic capsular release. As a double fellowship-trained surgeon, he sets expectations clearly: the great majority of patients recover their motion.
Non-surgical treatment
The mainstay is a structured physical therapy stretching program to restore motion, combined with anti-inflammatory measures to control pain. Consistency over time is what produces results, and most patients recover their motion with this approach.
Corticosteroid injection
A corticosteroid injection into the shoulder is often used, especially in the painful freezing phase. It can meaningfully reduce pain and shorten that phase, making the stretching program more tolerable and effective.
Refractory cases
For the small number of shoulders that stay stiff despite a committed program, two options can restore motion: manipulation under anesthesia, in which the surgeon gently moves the relaxed shoulder to free the tight capsule, and arthroscopic capsular release, in which the tightened capsule is divided through small portals. These are reserved for cases that do not respond to non-surgical care.
Recovery timeline
Recovery from frozen shoulder is measured in months, and the reassuring theme is that the large majority of shoulders regain their motion:
- Freezing phasePain control with anti-inflammatory measures and often a corticosteroid injection, plus gentle motion as tolerated.
- Frozen phaseA consistent stretching program to restore motion as the pain eases and stiffness dominates.
- Thawing phaseMotion gradually returns over months. Stretching and strengthening continue to recapture range.
- After a release or manipulationEarly, frequent motion is essential to hold the gains made, with a graded return to activity over weeks to months.
What patients commonly misunderstand
Two things that reassure patients with frozen shoulder.
- 'My shoulder will never move normally again.' The large majority of frozen shoulders recover their motion. The condition is self-limited and moves through freezing, frozen, and thawing phases, with motion returning in the thawing phase. It can take many months, and a consistent stretching program helps, but the natural history is recovery for most people.
- 'I need surgery to fix a frozen shoulder.' Most frozen shoulders never need surgery. The foundation of treatment is a stretching program, anti-inflammatory measures, and often a corticosteroid injection to shorten the painful phase. Manipulation under anesthesia or arthroscopic capsular release is reserved for the small number of cases that stay stiff despite a committed non-surgical program.
