A capsular release for frozen shoulder (adhesive capsulitis) is keyhole surgery that cuts the tight, thickened lining of the shoulder joint so the arm can move again. It is often combined with manipulation under anesthesia. Preparing well means planning for movement, not rest: exercises usually start within a day, several times a day, with frequent physical therapy over the first two weeks. Clear your calendar, line up help and agree on a pain plan before the day.
Your surgeon’s protocol comes first. The ranges here are typical, and your surgeon may give you different timings. Use theirs.
Key takeaways
- What it does: a capsular release cuts the tight joint lining through small keyhole incisions.
- Movement first: exercises usually begin the same day or the next, not after weeks in a sling.
- First two weeks: frequent exercise and physical therapy help keep the range gained during surgery.
- Pain plan: pain medicine timed before exercise helps many people do the work.
- Diabetes: blood sugar control before and after surgery is worth discussing with your doctor.
What the operation does
In frozen shoulder, the capsule, the bag of tissue that surrounds the shoulder joint, becomes thick, tight and stuck to itself. That is why the shoulder is stiff in every direction, even when someone else tries to move it for you.
- Arthroscopic capsular release: the surgeon uses a camera and small instruments through two or three keyhole incisions to cut the tightest parts of the capsule.
- Manipulation under anesthesia: while you are asleep, the surgeon moves the arm firmly to stretch and release the remaining tight tissue. It is often done straight after the release.
Surgery is usually considered when frozen shoulder has not improved enough after months of other treatment, such as physical therapy and injections. It opens the range. The weeks after surgery decide how much of it stays.
What to set up at home before
- Time: plan the first two weeks around exercise. Many people need several short sessions spread across the day, plus physical therapy visits.
- Physical therapy: book your first sessions before surgery, often within the first few days, and ask how often they should be in the first two weeks.
- Help with driving: arrange rides for about 1 to 3 weeks, including to physical therapy.
- Clothing: loose button-front tops and front-fastening bras for the first week or two, while the shoulder is sore.
- Sleeping position: extra pillows to sleep propped up, and one to rest under the arm.
- Exercise space: a clear wall to walk your fingers up, a table you can slide your arm along, and a light stick such as a broom handle for assisted movements.
What to practice before
- Assisted movements: learn the movements your surgeon or physical therapist will ask for, such as lifting the arm forward with help from the other arm, or sliding it along a table. Practicing the pattern now makes it easier when the shoulder is sore.
- Turning out with a stick: lying on your back, elbow by your side, pushing the hand outward with a stick held in the other hand.
- Relaxing the shoulder: letting the arm hang and swing gently while leaning forward, if your surgeon allows it.
- One-handed tasks: dressing and washing with the other arm leading, for the first few sore days.
Frozen shoulder surgery is the start of the movement work, not the end of it.
Questions to ask your surgeon
- Procedure: will you do a capsular release, a manipulation, or both?
- Range: will you tell me the range you achieved, so my physical therapist and I know the target?
- Exercise: when do I start, how often each day, and how far should I push?
- Sling: will I wear one at all, and for how long?
- Pain: will I have a nerve block, and how should I time my pain medicine around exercise?
- Diabetes: if I have diabetes, will a steroid injection during surgery affect my blood sugar, and how should I monitor it?
The first 48 hours
Most people go home the same day. A nerve block often numbs the arm for several hours, sometimes into the next day. Start pain medicine as your team advises, before the block wears off.
Once feeling returns, many surgeons want the first exercises started, using the other arm or a stick to move the operated arm through its new range. Expect it to be sore. Short, frequent sessions are usually easier than long ones. Ice packs wrapped in a cloth, used for short periods if your team allows, help many people after each session.
Call your surgeon or emergency number if
- Breathing: sudden breathlessness or chest pain. Call your local emergency number.
- Arm shape or color: the upper arm suddenly swells, looks out of shape, or the hand turns cold, pale or blue. Call your local emergency number.
- Numbness that stays: the arm is still numb or weak well after the block should have worn off. Call your surgeon.
- Wound or fever: redness around a keyhole wound, discharge, a temperature of 100.4°F (38°C) or higher, or chills. Call your surgeon.
- Calf: one calf becomes swollen, warm or painful. Call your surgeon the same day.
- Pain blocking exercise: pain stops you doing any of your exercises despite your medicine. Call your surgeon.

Plan the two weeks after frozen shoulder surgery as carefully as the day itself.
