Arthritis: An Overview
Arthritis simply means inflammation of a joint, and it causes pain, swelling and stiffness. Although each type has a different cause, the symptoms and much of the treatment overlap. Any joint can be affected, but arthritis is especially common in weight-bearing joints such as the knee, hip and spine. There is no cure, but many treatment options help manage pain and keep people active.
There are four broad categories. Osteoarthritis — the most common — is the gradual wearing of the smooth cartilage that cushions the joint, from ageing, overuse or previous injury, and often forms bone spurs. Inflammatory arthritis results from an overactive immune system (such as rheumatoid or psoriatic arthritis) or crystal build-up (gout and pseudogout), and usually needs specialist rheumatology care. Post-traumatic arthritis develops after a joint injury such as a fracture that damages the cartilage surface. Septic arthritis is a joint infection — typically a hot, red, acutely tender, swollen joint — which is a medical emergency needing urgent treatment. Diagnosis rests on the history, examination and, where needed, X-rays, blood tests or joint-fluid analysis.
For the common wear-and-tear forms, our role is to confirm the diagnosis and build a practical, rehabilitation-focused plan — exercise, weight management, activity modification and simple pain relief are the foundations, with other options considered where symptoms persist. We help identify features that point to an inflammatory or infective cause needing specialist or urgent care, and are clear about when a surgical opinion, such as joint replacement, becomes worthwhile.
Common symptoms
- Joint pain, swelling and stiffness
- Tenderness and pain when pressure is placed on the joint
- A grating feeling or sound (crepitus) with movement
- Reduced ability to move the joint, and weakness in the surrounding muscles

Evidence for twelve treatment options in arthritis: an overview
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 honest 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 for you
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 0.02-0.08% lignocaine 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
Trigger-point injection reviews address confirmed myofascial pain and find heterogeneous, generally low-certainty results; they do not establish the technique as treatment for the underlying diagnosis. Condition reviewed: arthritis overview.
Evidence source: Debrosse et al., trigger-point injection systematic review (2022)
Pairing reviewed 2026-08-30.
Where it fits for you
For arthritis overview, this may be considered only when examination finds a separate tender muscle band reproducing part of the pain. It does not treat the primary pathology and is used to help movement or rehabilitation.
Ultrasound-guided injections Guidance means we can see the needle reach the target. What goes into the needle depends on the diagnosis. Good support
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
Ultrasound improves needle-placement accuracy, but guidance is not a treatment in itself: benefit depends on a valid injectable target and what is injected. Condition reviewed: arthritis overview.
Evidence source: Oo et al., ultrasound-guided injection systematic review (2024)
Pairing reviewed 2026-08-30.
Where it fits for you
For arthritis overview, an ultrasound-guided injection is considered only when there is a specific diagnostic question or a separate joint, bursa, sheath or nerve target. The injectate and purpose are stated before treatment.
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 for you
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. Only if relevant
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
Shockwave reviews in myofascial pain report a possible benefit but mix protocols and often mix radial pressure wave with focused shockwave; that evidence cannot be transferred to the underlying diagnosis. Condition reviewed: arthritis overview.
Evidence source: Wu et al., shockwave for myofascial pain review (2022)
Pairing reviewed 2026-08-30.
Where it fits for you
For arthritis overview, radial pressure wave may be considered for a distinct superficial muscle or fascial component. It is not used as evidence of benefit for the primary diagnosis.
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 we use 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
The osteoarthritis evidence for shockwave is in the KNEE (Silva, Clin Rehabil 2022; Liao, Clin Rehabil 2019). There is no trial evidence at this joint.
Pairing reviewed 2026-08-30.
Where it fits for you
Reasonable to consider on the same mechanism, with the gap stated. Not a substitute for the loading and weight-management work that has the better evidence in arthritis generally.
EMTT (magnetotransduction therapy) High-energy magnetic pulses applied over the area. Painless, no contact. Plausible — no studies
What it involves
You sit with the applicator positioned over the area for a short session. Painless, no gel or contact required, and usually delivered 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 we can point to. 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 for you
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 we describe it 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. Plausible — no studies
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
No randomised trial of PRP in this condition. The PRP evidence sits in lateral epicondylitis, patellar tendinopathy, rotator cuff and gluteal tendinopathy, plantar fasciitis and knee osteoarthritis.
Pairing reviewed 2026-08-30.
Where it fits for you
Can be discussed on the same rationale, with the absence of direct trials, the cost and the fact that it is not a first-line option all stated.
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
The prolotherapy osteoarthritis evidence is overwhelmingly in the KNEE, where it is strong (Chen, Clin Rehabil 2022; Liao, Int J Mol Sci 2023). There are no comparable trials at this joint.
Pairing reviewed 2026-08-30.
Where it fits for you
Reasonable to consider on the same rationale, with the gap in the evidence stated. Discussed alongside the loading work rather than instead of it.
Viscosupplementation (hyaluronic acid) A gel-like injection into an arthritic joint. Widely used, and genuinely contested. Plausible — no studies
What it involves
One or a short series of hyaluronic acid injections into the joint under ultrasound guidance.
What the evidence shows
The viscosupplementation trials are overwhelmingly in the knee, and even there the guideline bodies disagree. There are no comparable data at this joint.
Pairing reviewed 2026-08-30.
Where it fits for you
Rarely relevant here. Discussed only where the knee-based rationale is explained along with the gap.
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. Only if relevant
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
Perineural dextrose evidence is concentrated in diagnosed peripheral compression neuropathies, particularly the upper limb; no direct evidence was identified for this diagnosis itself. Condition reviewed: arthritis overview.
Evidence source: Perineural dextrose for upper-limb entrapment neuropathy review (2025)
Pairing reviewed 2026-08-30.
Where it fits for you
For arthritis overview, perineural treatment may be considered only if a separate superficial neuropathic pain pattern is found on examination. It is not treatment of the primary diagnosis.
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
Hydrodissection evidence is concentrated in ultrasound-confirmed peripheral nerve entrapment, especially carpal tunnel syndrome; no direct evidence was identified for this diagnosis itself. Condition reviewed: arthritis overview.
Evidence source: Buntragulpoontawee et al., hydrodissection injectate review (2021)
Pairing reviewed 2026-08-30.
Where it fits for you
For arthritis overview, hydrodissection may be considered only if ultrasound and examination identify a separate compressed or tethered peripheral nerve. It is not treatment of the primary diagnosis.
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.
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 we do not build treatment plans around it. Where an injection is the right call, we review the specific diagnosis and target, discuss what is being injected and why, keep the number low, and pair it with the loading work that changes the longer-term course.
When we would still consider it
- 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 tells us where the pain is coming from
When a cortisone injection is worth doing, and when it is not
Other general 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.
