Shoulder Osteoarthritis
Written by Dr Joshua Hatch, Musculoskeletal GP, RACGP Fellow, Diploma in Musculoskeletal Medicine (FSEM UK).
Shoulder osteoarthritis refers to degenerative change in the shoulder joint surfaces. It can be associated with stiffness, deep aching pain and reduced confidence using the arm. Some people notice a grinding sensation or difficulty sleeping on that side.
Assessment helps clarify whether pain is mainly from the glenohumeral joint, the acromioclavicular joint, the rotator cuff, or the neck. This distinction matters because treatment and expected response can differ.
Non-surgical care usually includes maintaining comfortable movement, strengthening the shoulder girdle, adapting aggravating loads and considering injections when the pain generator and goal are clear. The plan should be realistic about what treatment can and cannot change.
Common symptoms
- Deep shoulder pain or aching
- Stiffness and reduced range of motion
- Grinding, catching or painful clicking
- Difficulty with overhead activity, dressing, pushing or sleeping

Evidence for twelve treatment options in shoulder osteoarthritis
This is not a fixed ladder or a package of treatments. Every option is assessed independently against this diagnosis, including treatments with limited direct research that may still be reasonable for a clearly defined tissue target. The evidence level, likely benefit, risks, cost and alternatives are weighed at consultation.
Foundation: diagnosis, education and rehabilitation
The part of care with the broadest relevance. For many people it is enough on its own; other options are judged against it, not automatically added after it.
Diagnosis, education and progressive rehabilitation Working out what is driving the pain, explaining what your imaging does and does not mean, and building a graded loading plan you can actually follow. Core care
What it involves
Assessment to identify the likely pain source, an explanation of what the diagnosis means, adjustment of the loads that aggravate it, and a progressive strength and conditioning plan, with weight management where that is clinically relevant.
What the evidence shows
Exercise is the core treatment, and it performs as well as the tablets. A network meta-analysis of 152 randomised trials and 17,431 patients found exercise gave the same pain relief and functional improvement as oral anti-inflammatories and paracetamol, with a far better safety profile (Weng, Br J Sports Med 2023). EULAR (Moseng, Ann Rheum Dis 2024) and the American College of Rheumatology (Kolasinski, Arthritis Rheumatol 2020) both make exercise, education and weight management the core of non-pharmacological care. An individual-participant meta-analysis of 31 trials and 4,241 patients is clear about the size of it: the average effect is small and of questionable clinical importance, and those with more pain and worse function at the start benefit most (Holden, Lancet Rheumatol 2023).
Pairing reviewed 2026-09-02.
Where it fits
Worth being straight about: the average effect is modest, and it is larger for people who are struggling more to begin with. What it does have over the alternatives is that it is safe to keep doing, and it works on the things a joint injection cannot: strength, capacity and weight.
Muscle and symptom-modifying options
Useful only when the examination identifies the tissue they target or when short-term pain control creates a useful rehabilitation window.
Wet needling and trigger point injection (trigger point injection) A fine needle into a tender band of muscle, with a small volume of dilute glucose solution injected through it. Only if relevant
What it involves
The needle is placed into the tender muscle band and a small volume of 5% glucose with a very dilute local anaesthetic (0.02-0.08%) is injected. Often done in the same visit as your assessment, and usable where the tender area sits deeper. Dry needling (the same technique with nothing injected) is not offered here.
What the evidence shows
No study has tested any needling technique in shoulder osteoarthritis. A search pairing dry needling, trigger point needling and trigger point injection with arthritis of the shoulder, elbow, wrist, thumb base and big toe returned 19 records, and none tested needling in an arthritic shoulder; the shoulder records were reviews of other ultrasound-guided procedures (Messina, Br J Radiol 2015) or concerned the rotator cuff. A second pass restricted to clinical trials returned five records, none at this joint.
Pairing reviewed 2026-10-01.
Where it fits
Only where the assessment finds a separate tender muscle band around the shoulder reproducing part of the pain. It does not treat the arthritic joint.
Ultrasound-guided injections Guidance means the needle can be seen reaching the target. What goes into the needle depends on the diagnosis. Large placebo effect
What it involves
The injection is performed under ultrasound so the needle can be watched into the target structure. What is injected is decided by the diagnosis, and corticosteroid is used sparingly, for the reasons set out below.
What the evidence shows
Injections into an arthritic shoulder reliably improve symptoms, but so do dummy injections. In a multicentre double-blind randomised trial of 300 people, three weekly hyaluronate injections improved pain by 19.9 mm on a 100 mm scale against 16.3 mm for buffered saline, a difference that was not statistically significant (Kwon, J Shoulder Elbow Surg 2013). A meta-analysis found hyaluronic acid reduced pain by 26.2 mm at three months (95% CI 22.0 to 30.3) while noting that control groups improved to a similar degree (Zhang, J Shoulder Elbow Surg 2018). A systematic review of 1,125 shoulders found consistent but modest benefit from hyaluronic acid, limited evidence for platelet-rich plasma and stem cell preparations, and a 7.2 per cent complication rate (Migliorini, Eur J Med Res 2025); in a double-blind randomised trial of 70 people, ultrasound-guided platelet-rich plasma and hyaluronic acid were no different from one another at any point over 12 months, and both improved (Kirschner, Clin J Sport Med 2022).
Pairing reviewed 2026-09-10.
Where it fits
Reasonable when pain is blocking the strengthening and range work, with the size of the likely benefit set out. Used sparingly: see the note on cortisone.
V-ACTOR vibration therapy (vibration therapy) Low-frequency vibration applied over tender muscle. Not a shockwave, despite sharing the machine. Plausible: no studies
What it involves
A vibration handpiece is moved over the tender muscle and fascia for a few minutes. It runs from the same STORZ MASTERPULS icon console as radial shockwave but is a separate handpiece delivering a different, gentler form of energy. No needles, no anaesthetic, no downtime.
What the evidence shows
No published clinical trial of this device in this condition. It is a vibration handpiece delivered from the same console as radial shockwave, and the rationale is myofascial rather than tendon- or bone-directed.
Pairing reviewed 2026-08-30.
Where it fits
A comfort measure used within a session where muscular tightness is limiting movement. Never the reason for the appointment, and not a substitute for the treatments that do have evidence.
Energy-based treatment options
Radial pressure wave, focused shockwave and EMTT have different targets and different evidence. They are assessed separately rather than treated as one category.
Radial or focused shockwave? Read the overviewRadial shockwave (radial pressure wave) Broad treatment across tender muscle and fascia, close to the surface. No studies at this joint
What it involves
A handpiece is moved over the tender tissue while ballistic pressure pulses are delivered, using a transmitter head chosen for the tissue, including heads shaped for fascia and for the muscle either side of the spine. The pulse is strongest at the skin and weakens with depth, so this is mainly a myofascial treatment, though it can reach deeper in some areas. No anaesthetic, no downtime, usually a course of sessions about a week apart.
What the evidence shows
Searching shockwave, shock wave, ESWT and radial shockwave against shoulder and glenohumeral osteoarthritis returns no trial of either device in this condition, and restricting the same search to randomised trials returns a single record which turns out to be about rotator cuff tendon pain rather than arthritis (Saggini, J Biol Regul Homeost Agents 2010). The shoulder shockwave literature is calcific tendinopathy and rotator cuff disease, which are different problems at different structures.
Pairing reviewed 2026-09-25.
Where it fits
Offered for the tender muscle around an arthritic shoulder, commonly the cuff and the muscle between the shoulder blade and the spine, rather than for the joint. If the scan shows a calcific deposit or a cuff tendon problem alongside the arthritis, that is where shockwave has its evidence.
Focused shockwave (ESWT) A true shock wave converging at depth: for tendon, joint, ligament and bone. Plausible: no studies
What it involves
A focused system generates an acoustic shock wave that converges at a focal point set at a defined depth, concentrating the energy where the target is. This is the form used for tendon, joint, ligament and bone. Typically four to six sessions about a week apart, no anaesthetic and no formal downtime.
What the evidence shows
No trial has tested shockwave for shoulder osteoarthritis: searching shockwave, shock wave and ESWT against shoulder and glenohumeral osteoarthritis returns no study of either device. The case for it rests on other arthritic joints. Pooled trials at the knee favour shockwave over sham for pain and function (Tang, Int J Surg 2024), and at the hip a 148-person trial found focused shockwave better than sham (Şah, J Pers Med 2022). Shockwave's own evidence at the shoulder is in calcific tendinopathy and rotator cuff disease, which are separate conditions with their own guides.
Pairing reviewed 2026-10-04.
Where it fits
A reasonable option to try on the strength of the knee and hip trials, with the gap at this joint explained. Most useful where a cuff tendon problem or calcific deposit is contributing alongside the arthritis, since that is where the shoulder evidence is. Alongside the movement and strength programme, not instead of it.
EMTT (magnetotransduction therapy) High-energy magnetic pulses applied over the area. Usually painless, no contact. Plausible: no studies
What it involves
You sit with the applicator positioned over the area for a short session. It is usually painless and needs no gel or skin contact. It is usually given as a course, commonly alongside shockwave.
What the evidence shows
There are no published randomised trials of EMTT in this condition, or in any musculoskeletal condition, that could be identified. The supporting work is laboratory work: EMTT increased tenocyte proliferation, migration and collagen expression in cultured human tendon cells (Mancini, Int J Mol Sci 2025). The nearest human evidence for a related electromagnetic therapy is negative. A randomised trial of pulsed electromagnetic field therapy added to eccentric exercise for Achilles tendinopathy found no improvement in outcome scores or tendon neovascularity over eccentric exercise alone (Ko, Orthop J Sports Med 2024).
Pairing reviewed 2026-08-30.
Where it fits
Offered only as an adjunct alongside treatment that does have evidence, never as the plan itself, and only after that gap is explained. Much of the EMTT literature is manufacturer-affiliated, which is part of why it is described this way.
Biologic and joint injection options
Each injection is assessed independently for the named diagnosis. Cost, uncertainty, likely benefit, risks and alternatives are part of the decision.
Platelet-rich plasma (PRP) Your own blood, concentrated and injected under ultrasound guidance. One trial, equal to hyaluronic acid
What it involves
Blood is taken from your arm, spun to concentrate the platelets, and injected into the target under ultrasound guidance in the same appointment.
What the evidence shows
One randomised trial at this joint, and it found no difference from the comparison injection. Seventy people with glenohumeral osteoarthritis were randomised, double-blind, to a single ultrasound-guided injection of leukocyte-poor PRP or hyaluronic acid into the joint. Pain and function improved in both groups from one to two months and stayed improved to twelve months, with no difference between them at any point and no effect of how many platelets the PRP contained (Kirschner, Clin J Sport Med 2022). There was no dummy-injection arm, and hyaluronic acid itself did not clearly beat saline in a 300-person trial at this joint (Kwon, J Shoulder Elbow Surg 2013), so how much of the improvement was due to either injection is not known. Outside trials the picture is thin. In a French multicentre review of arthritic shoulders in people under 50, 28 were treated with PRP and 88 with viscosupplementation, and together these were reported to postpone joint replacement by an average of 3.5 years in 86% - pooled, retrospective and uncontrolled (Kany, Orthop Traumatol Surg Res 2020). In a single-clinic series, the 12 treated for shoulder arthritis had the poorest results of any group at six months, with unsatisfactory outcomes outnumbering satisfactory ones (Godek, Ortop Traumatol Rehabil 2022). A systematic review of injections for this condition judged the evidence for PRP and other orthobiologics limited (Migliorini, Eur J Med Res 2025).
Pairing reviewed 2026-10-08.
Where it fits
Can be discussed where shoulder arthritis pain is limiting the range and strengthening work and simpler measures have not been enough, with the evidence stated as it is: one trial, no better than the comparison injection, and no trial against a dummy injection. Reviewed at about three months and not repeated without a clear benefit.
Prolotherapy (dextrose) A course of dextrose injections into and around the structure and its attachments. Plausible: no studies
What it involves
Hypertonic dextrose is injected at the tender ligament and tendon attachments, and into the joint where relevant, usually as a series of treatments a few weeks apart.
What the evidence shows
No clinical study of prolotherapy in shoulder arthritis. A search on 12 October 2026 for dextrose or prolotherapy in arthritis of the shoulder returned seven records. A systematic review of injected biological treatments at the shoulder found five prolotherapy studies, all in rotator cuff problems, and no study in glenohumeral arthritis that met its criteria (Robinson, J Back Musculoskelet Rehabil 2021). The nearest report is a single man with long-standing shoulder pain, not stated to be arthritis, injected into the joint, the acromioclavicular joint, the space under the acromion and the supraspinatus attachment, who reported 90% less pain after three sessions (Seenauth, Altern Ther Health Med 2018). The trials of dextrose injection into an arthritic joint are in the knee and the fingers (Chen, Clin Rehabil 2022; Reeves, J Altern Complement Med 2000).
Pairing reviewed 2026-10-12.
Where it fits
Prolotherapy is offered here and can be discussed for shoulder arthritis pain that persists despite a shoulder exercise program, with the absence of studies at this joint stated. Where the rotator cuff is the main source of pain, the cuff evidence on that page is the better guide. Any injection is there to make the exercise work possible, not to replace it.
Viscosupplementation (hyaluronic acid) A gel-like injection into an arthritic joint. Widely used, and genuinely contested. Edge over saline too small to feel
What it involves
One or a short series of hyaluronic acid injections into the joint under ultrasound guidance.
What the evidence shows
Searched PubMed for hyaluronic acid, hyaluronate, hyaluronan, viscosupplementation or hylan with glenohumeral or shoulder osteoarthritis: 21 records with a trial filter and 8 reviews. Two large multicentre trials compared hyaluronic acid with saline injected into the shoulder joint, and both missed their main goal. In 660 people with persistent shoulder pain, five or three weekly injections did not beat saline at 13 weeks; the people with arthritis did better than saline over 26 weeks in a secondary analysis (Blaine, J Bone Joint Surg Am 2008). In 300 people with shoulder arthritis, three weekly injections improved pain by 20 mm on a 100 mm scale against 16 mm with saline at 26 weeks, which was not a significant difference; in those with no other shoulder problem the gap was 4 mm (Kwon, J Shoulder Elbow Surg 2013). A review found the difference from placebo never reached the smallest change patients notice (Colen, Int J Shoulder Surg 2014), and a diclofenac-hyaluronate conjugate was no better than placebo in the shoulder group of a four-joint trial (Kubo, BMC Musculoskelet Disord 2022). On the other side, a meta-analysis of 15 trials and 1,023 people found less pain than after a cortisone injection, and better results with physiotherapy than physiotherapy alone (Familiari, J Orthop Res 2023), and a 2025 review called the benefit consistent but modest (Migliorini, Eur J Med Res 2025).
Pairing reviewed 2026-10-26.
Where it fits
May be discussed for shoulder arthritis where cortisone is unsuitable or has been used repeatedly, to settle pain enough to keep the strengthening and range-of-movement program going. Expect an improvement close to what a saline injection gives, possibly a little more, and longer-lasting than cortisone.
Nerve-targeted options
Relevant when examination identifies a superficial neuropathic pattern or a compressed peripheral nerve, not simply because pain is present.
Lyftogt perineural therapy (perineural injection therapy) A series of small dilute dextrose injections just under the skin, over tender superficial nerves. No study in shoulder arthritis
What it involves
Small injections of low-concentration dextrose, usually 5%, placed just beneath the skin along tender superficial nerves. Given as a series of short sessions.
What the evidence shows
No study has tested perineural dextrose injection in shoulder (glenohumeral) osteoarthritis. A PubMed search pairing perineural injection, neural prolotherapy, subcutaneous or perineural dextrose, glucopuncture or neurofascial injection with the shoulder, elbow, wrist and hand returned 33 records, a second pass against arthritis, osteoarthritis, rheumatoid arthritis and gout returned 35, and separate passes for randomised trials and systematic reviews returned 44; none was in shoulder arthritis. The nearest trials are in a different condition, subcutaneous and perineural dextrose for rotator cuff tendinopathy (Kazempour Mofrad, J Clin Rheumatol 2021; Vitoonpong, Asian Biomed 2026), and they cannot be carried across to an arthritic joint.
Pairing reviewed 2026-11-11.
Where it fits
Considered only where examination finds a tender, hypersensitive skin nerve territory around the shoulder alongside the arthritis; suprascapular nerve pain is the pattern that occasionally fits. Pain from inside the joint is not what this treats, and the strengthening and range-of-movement program stays the main treatment.
Ultrasound-guided nerve hydrodissection Fluid placed around a nerve to free it from the surrounding tissue. Only if relevant
What it involves
Under ultrasound, fluid is placed in the plane around the nerve to separate it from the tissue that is tethering or compressing it.
What the evidence shows
No trial has tested hydrodissection in shoulder osteoarthritis. Hydrodissection, hydrorelease, hydrodilatation, brisement and perineural injection searched against glenohumeral and shoulder osteoarthritis returned three records: a clinical commentary proposing capsular hydrodilatation with physiotherapy, with no outcome data (Liotta, Int J Sports Phys Ther 2025); a single retrospective case of a proprietary amniotic-membrane allograft injected by hydrodissection (Sullivan, Orthop Nurs 2025); and a narrative review (Vargas-Figueroa, Cureus 2025): distending the joint capsule is a different procedure from separating a nerve from surrounding tissue.
Pairing reviewed 2026-09-29.
Where it fits
Only if assessment suggests a separate nerve pain source alongside the arthritis; suprascapular nerve pain is the pattern that occasionally fits.
This is general information only and suitability is assessed individually. Treatments with limited or condition-dependent evidence may still be discussed, but only with clear explanation of the uncertainty, the expected benefit, risks, cost and alternatives. Red flags, progressive neurological symptoms or suspected serious pathology require a different pathway.
Every treatment above is described in full on the non-surgical treatments page, including what each one is used for and what the evidence supports. Ratings apply to the named diagnosis; an adjacent muscle, tendon, joint or nerve problem is assessed as a separate target. The method behind the ratings, and the treatments not offered, are set out on the evidence page.
Corticosteroid injection is reviewed separately for each diagnosis.
Cortisone reliably reduces pain in the short term, and that can be genuinely useful when pain is stopping you sleeping or moving enough to rehabilitate. Beyond that window the picture changes. A systematic review of 41 randomised trials and 2,672 participants found that corticosteroid injection reduced pain in the short term but that the effect reversed at intermediate and long term; in pooled analysis for lateral epicondylalgia the short-term effect was large (SMD 1.44, 95% CI 1.17 to 1.71) while no intervention was favoured at 26 weeks (-0.40, -0.67 to -0.14) and at 52 weeks (-0.31, -0.61 to -0.01) (Coombes, Lancet 2010). In a randomised trial in lateral epicondylalgia, 83 per cent of the corticosteroid group had completely recovered or much improved at one year against 96 per cent given a placebo injection, and recurrence ran at 54 per cent against 12 per cent; adding physiotherapy made no significant difference at one year (Coombes, JAMA 2013). In joints, repeated corticosteroid injections have been associated with cartilage loss. It does not repair anything.
So treatment plans are not built around it. Where an injection is the right call, the specific diagnosis and target are reviewed, what is being injected and why is discussed, the number is kept low, and it is paired with the loading work that changes the longer-term course.
When it might still be considered
- Pain severe enough to block rehabilitation
- A clear inflammatory or bursal target on imaging
- A specific short-term goal: a trip, a procedure, a return to work
- Diagnostic use, where the response shows where the pain is coming from
When a cortisone injection is worth doing, and when it is not
Other shoulder conditions
Pain in the same area can come from more than one source, and the label matters less than what the examination and history point to. These are the other guides for this region.
