The problem

The right operation, the right rehab, and the honest conversation about when not to operate.

A frozen shoulder is where general orthopaedics quietly under-delivers - the hydrodilatation step is skipped, physio is booked too late, or a blind MUA is done on a shoulder that needed a release under vision.

  • Try distension first, when it fits

    For many stage 2 shoulders, a hydrodilatation delivers most of the benefit without a theatre. We say so up front.

  • Release under vision, not blind

    A 360-degree arthroscopic release protects the axillary nerve and the humeral shaft in a way blind MUA cannot.

  • Book physio before you book theatre

    The first six weeks after release decide the final range.

When it helps

When arthrolysis is the right step.

The situations we see most, plus the one red flag that means A&E rather than a routine booking.

  • Stage 3 adhesive capsulitis

    A frozen shoulder past the freezing phase - pain has settled but range is stuck. Passive external rotation is the giveaway sign.

  • Failed conservative treatment

    Six months of physiotherapy, NSAIDs and at least one image-guided steroid injection with no meaningful gain in movement.

  • Post-surgical stiffness

    Stiffness after cuff repair, stabilisation or fracture fixation that has plateaued despite good rehabilitation.

  • Diabetes-related capsulitis

    Frozen shoulder in diabetic patients tends to be more severe, longer lasting and more likely to need release than resolve on its own.

  • Recurrent capsulitis

    A second frozen episode in the same shoulder, or contralateral capsulitis with a history that failed to fully recover the first time.

  • Post-fracture capsular contracture

    A tight, painful capsule after proximal humerus or clavicle fracture where physiotherapy alone has hit a ceiling.

  • Occupational urgency

    A surgeon, hairdresser, painter or overhead worker who cannot afford the 12–24 month natural history of the condition.

  • Red flag: night pain with red hot swollen joint

    A shoulder that is hot, swollen and severely painful at night is not a frozen shoulder - septic arthritis needs same-day A&E, not a routine booking.

Procedure options

Approach and extent depend on the stage and the shoulder.

What each option involves - MUA alone, arthroscopic release, or the two combined, and where hydrodilatation fits as a lower-risk step before theatre.

  • Manipulation under anaesthetic (MUA)

    Gentle graded stretching under GA to tear the tightest capsular bands. Quick, cheap, effective in early cases - but can cause humeral fracture in osteoporotic bone if forced.

  • Arthroscopic capsular release

    Keyhole division of the anterior, inferior and posterior capsule and the rotator interval under direct vision. Preferred where MUA has failed or the capsule is very thickened.

  • 360-degree release

    Circumferential division including the posterior capsule - used for the truly recalcitrant shoulder, diabetic capsulitis, or post-surgical contracture where partial release will not deliver.

  • Combined MUA and arthroscopic release

    The standard approach in the UK - release the capsule under vision, then complete a gentle MUA to confirm free glenohumeral motion end-of-case.

  • Open capsular release

    Reserved for the very rare case where scarring is extra-articular or where a deltopectoral approach is needed for concurrent hardware removal.

  • Release with subacromial decompression

    Where impingement coexists - the acromioplasty is added at the same sitting to remove the mechanical source of ongoing stiffness.

  • Release with rotator cuff repair

    A tight, stiff shoulder overlying a small cuff tear - release restores glide before the cuff is repaired to a mobile tendon.

  • Hydrodilatation first, arthrolysis second

    For many patients an image-guided saline distension with steroid delivers 60–70 percent of the benefit at a fraction of the cost. We say so when it fits.

Safety and recovery

What to expect afterwards - honestly.

Arthrolysis is a well-established, low-risk operation. The things worth planning for are the first six weeks of physiotherapy and the small chance that range slips and needs topping up.

  • GA with interscalene block, in a proper theatre

    The block controls pain for 12–18 hours and lets physio start the same day. Day-case is the norm; one night if pain is heavier or you live far away.

  • Humeral fracture during MUA

    A well-documented risk of manipulation, especially in older or diabetic bone. Under 1 percent in careful hands and one reason we prefer release-under-vision to blind manipulation.

  • Bleeding and haemarthrosis

    A small bleed into the joint is common; a symptomatic haemarthrosis needing aspiration is under 2 percent. The block masks pain - swelling and warmth are the signs to call about.

  • Nerve injury

    Axillary nerve neurapraxia is rare but recognised, particularly during inferior capsular release. Numbness in the deltoid patch usually settles within weeks.

  • Infection

    Deep infection under 0.5 percent for arthroscopic work. Any spreading redness, fever above 38, or wound discharge needs the same-day team, not a routine call.

  • Range slips at 6 weeks

    Around 10–15 percent lose some of the gained range as the block wears off and scarring restarts. Aggressive physio, hydrodilatation or repeat release rescues most.

  • Physio is the operation

    The result at 3 months is decided by the first 6 weeks of physiotherapy. Skipping sessions is the single most common cause of a disappointing outcome.

  • Diabetic recovery is slower

    Type 1 and type 2 diabetics take longer to regain range and are more prone to recurrence. We build a longer physio block and closer follow-up into the plan up front.

  • Red flags after surgery

    Fever, spreading redness, calf pain, breathlessness, new hand weakness or numbness that fails to settle after 24 hours need the same-day team or A&E.

Reading your operation note

Your operation note in four parts. Read the last one first.

Whether the surgeon did an MUA, an arthroscopic release, or both, the note keeps to the same shape.

  3. 03 Findings

    Intra-articular findings

    Capsular thickness, synovitis grade, any cuff or labral pathology seen, cartilage status. This shapes prognosis and the physio protocol.

Arthrolysis is usually covered when a frozen shoulder has failed conservative treatment. Physiotherapy is often covered under the same episode.

Frequently asked

Everything we get asked about shoulder arthrolysis.

Quick answers on MUA versus release, recovery, physio and cost.

  • How is shoulder arthrolysis different from a manipulation under anaesthetic?

    MUA is a blind stretch under general anaesthetic that tears the tightest capsular bands. Arthrolysis is a keyhole operation that divides the thickened capsule under direct vision, portal by portal. In the UK the two are usually combined - arthroscopic release first, then a gentle MUA to confirm free motion.

  • Do I really need surgery for a frozen shoulder?

    Most frozen shoulders resolve within 12–24 months with physiotherapy, NSAIDs and steroid injections. Arthrolysis is for the minority whose stiffness has plateaued past six months, who cannot afford the natural history - diabetics, overhead workers, surgeons - or where a post-surgical contracture will not release with rehabilitation alone.

  • How long is recovery after arthroscopic capsular release?

    Most patients are back to desk work in a week and driving in one to two weeks. Full functional range and overhead activity typically returns at three months, sometimes longer in diabetic patients.

  • Will the frozen shoulder come back after arthrolysis?

    Around 10–15 percent of patients lose some of the range gained on the table as the interscalene block wears off and healing restarts. Intensive physiotherapy in the first six weeks is the single biggest determinant of the final outcome. A small number need a hydrodilatation or a repeat release.

  • How much does private shoulder arthrolysis cost in the UK?

    Physiotherapy is an additional £720–£1,320 for a 12-session package.

  • Is hydrodilatation a good alternative to arthrolysis?

    For many patients hydrodilatation - image-guided saline distension of the joint with a steroid - delivers 60–70 percent of the benefit of surgery at a fraction of the cost, in the outpatient X-ray suite.
