Knee Osteoarthritis
Quick summary
Painful knee arthritis? Ultrasound-guided steroid, hyaluronic acid and Arthrosamid® injections in Oxford — clinically proven long-term relief.
Knee osteoarthritis is the leading cause of chronic knee pain in adults over 50. A stepped approach combining rehab, guided injections and, where appropriate, Arthrosamid® keeps most patients out of the operating theatre.
Key takeaways
- Painful knee arthritis? Ultrasound-guided steroid, hyaluronic acid and Arthrosamid® injections in Oxford — clinically proven long-term relief.
- Diagnosed with in-clinic ultrasound alongside clinical examination.
- Treated with a stepped, evidence-based plan — not one-size-fits-all injections.
- Self-referral available — no GP letter required.
Symptoms
- Anterior or medial knee pain worse with stairs and squatting
- Morning stiffness under 30 minutes

Who is most at risk
- Age over 50
- Previous meniscus or ACL injury
- Occupational kneeling or heavy lifting
- Higher BMI — a strong modifiable risk factor
- Family history
Differential diagnosis
Conditions that can mimic Knee Osteoarthritis.
- Meniscus tear (mechanical locking)
- Patellofemoral pain syndrome
- Pes anserine bursitis
- Baker's cyst
- Inflammatory arthropathy (bilateral, systemic features)
How we diagnose Knee Osteoarthritis
Standing X-ray grades joint space narrowing (Kellgren-Lawrence). Ultrasound identifies effusion, Baker's cysts and meniscal extrusion, and confirms accurate needle placement for any injection.
Treatment options
Guided steroid + local anaesthetic
Best for acute flares with effusion. Provides weeks to months of relief.
Hyaluronic acid (Durolane / Ostenil)
Single or course injections; useful in early-moderate OA and for steroid-averse patients.
Arthrosamid®
One-off hydrogel giving lasting relief in moderate-severe OA — an increasingly popular alternative to repeat HA courses.
Rehabilitation
Quadriceps strengthening reduces pain independent of imaging severity.
What we look for on ultrasound
Suprapatellar effusion, medial meniscal extrusion, marginal osteophytes, popliteal (Baker's) cyst.
When to seek help
Book if the knee is limiting daily activity, gives way, or if you've been offered a replacement and want to explore alternatives.
Recovery timeline
Typical timeframes after diagnosis and treatment. Individual recovery varies — your clinician will personalise this plan.
- 1Week 0–2Post-injection
Rest 24–48 hours after steroid; back to normal walking within days.
- 2Month 1–3Loading
Progressive quadriceps and glute loading. Cycling and swimming ideal.
- 3Month 3–12Maintenance
Repeat HA/Arthrosamid® when needed; weight optimisation reduces symptom recurrence.

How we make treatment decisions
Every recommendation at Oxford Injection Clinic is shaped by current UK guidance — including NICE recommendations for musculoskeletal pain, published NHS guidance on injection therapy, and peer-reviewed evidence from British and international MSK medicine journals. We follow a stepped-care model: accurate diagnosis first (clinical examination and diagnostic ultrasound), conservative measures where appropriate, and image-guided injection or referral only when clinically indicated. Consultant physiotherapist Bob Chandran reviews the latest MSK literature and updates our clinical protocols routinely.

Frequently asked questions
Which injection is best for me?
It depends on severity, activity level, previous response and preferences. We'll discuss all three at your consultation.
Can I still run?
Yes, in most cases. Running does not accelerate OA and helps maintain joint health when done sensibly.

Expert MSK care in Oxford
Oxford Injection Clinic is the specialist musculoskeletal service of GB Clinic Oxford, an independent physiotherapy and interventional MSK clinic based in Botley. Our consultants and advanced practitioners assess, scan and treat the full spectrum of joint, tendon, ligament and nerve problems — from acute sports injuries to long-standing arthritis. Every clinician is HCPC-registered and holds post-graduate qualifications in diagnostic ultrasound, injection therapy or advanced musculoskeletal practice.
We believe the fastest route to recovery is an accurate diagnosis on day one. That is why every consultation includes a full history, a hands-on clinical examination and, where useful, a real-time high-resolution ultrasound scan. If an ultrasound-guided injection is likely to help, we can usually perform it in the same visit — no separate trips, no waiting weeks for imaging.
Evidence-based, patient-led
Not everyone needs an injection. Our clinicians follow NICE, BOA and international best-practice guidance to decide when injections, shockwave therapy, hydrodilatation, barbotage or a structured loading programme is the right next step. Where surgery is genuinely the best option we say so, and we can refer to trusted orthopaedic and pain specialists across Oxford, London and the Thames Valley.
Patients travel to see us from Botley, Summertown, Headington, Cowley, Iffley, Abingdon, Witney, Kidlington, Bicester, Didcot, Wallingford, Wantage, Wheatley, Thame, Woodstock, Chipping Norton, Banbury, Henley-on-Thames and Reading.
