Knee Pain Management and Injections in London: Treatment Without Surgery
Knee pain management and injections aim to ease pain and keep you active without an operation. Mr Sivan Sivaloganathan, Consultant Orthopaedic Surgeon in London, combines exercise, weight advice and painkillers with steroid, hyaluronic acid or platelet-rich plasma (PRP) injections where they fit. NICE guidance sets out the evidence for each one.
His non-surgical clinic sees early to moderate knee arthritis, thinning cartilage behind the kneecap and knees that swell after activity. Under NICE NG226, an examination is normally enough to confirm osteoarthritis from the age of 45 when pain comes with activity.
The injections are not equal. Steroid helps for a limited window, put at 2 to 10 weeks by NICE, which also advises against hyaluronic acid injections for osteoarthritis. Its 2019 PRP guidance calls the evidence limited in quality.
What Is Non-Surgical Knee Pain Management?
It is a plan built from treatments that do not need an operation. NICE guideline NG226 names therapeutic exercise and weight management, with information and support, as the core treatments for osteoarthritis. Medicines and injections are added to help you keep exercising.
The NHS osteoarthritis treatment guide calls exercise one of the most important treatments, whatever your age or fitness. It also notes that extra weight puts strain on the joints and worsens symptoms.
A joint injection places medicine straight into the space inside the knee. At his clinics, steroid and hyaluronic acid injections can be guided by ultrasound, and PRP is prepared and given in an operating theatre (his practice website).
Knee Pain Symptoms: When to Get Help
Most knee pain can be eased at home over a few days, according to the NHS. Some signs need faster help, as the table shows.
| Your symptom | Possible cause | What to do |
|---|---|---|
| Activity-related pain, morning stiffness under 30 minutes, aged 45 or over | Osteoarthritis (NICE NG226) | GP, physiotherapy or a specialist review |
| Knee that feels full, tight and swollen | Inflammation or fluid in the joint (his practice website) | Book an assessment |
| Knee locks, gives way or clicks painfully | Meniscal tear or ligament damage (NHS) | Advice from NHS 111 |
| Swelling, warmth and bruising while taking blood-thinning medicines | Bleeding in the joint (NHS) | Advice from NHS 111 the same day |
| Hot, red knee with a high temperature, including after an injection | Joint infection (septic arthritis) (NHS, Versus Arthritis) | Urgent GP appointment or NHS 111. A&E if you feel very unwell |
| Slurred speech, confusion, mottled skin, very fast breathing | Possible sepsis (NHS) | Call 999 or go to A&E |
The NHS septic arthritis page asks for urgent help if a painful joint comes with a high temperature or shivering. A joint infection after an injection is very rare, Versus Arthritis says, but it needs a doctor at once.
Conditions Mr Sivaloganathan Treats Without Surgery
- Early to moderate knee osteoarthritis: the group his practice describes as most suited to injection treatment. NICE NG226 covers it from age 16.
- Thinning cartilage behind the kneecap (chondromalacia): often felt as stiffness. His practice uses hyaluronic acid here, a private option NICE does not support for osteoarthritis.
- A swollen, inflamed knee: fluid and inflammation are the usual targets for a steroid injection (his practice website, NHS).
- Cartilage damage or early wear: his practice uses PRP here, an option NICE HTG497 limits to special arrangements for consent and audit.
- Pain from a meniscal tear during rehabilitation: a steroid injection can ease pain enough to exercise (Sherwood Forest NHS). Tears that need surgery are covered on the knee injuries and meniscal repair page.
- Repetitive strain injuries: overuse pain around the knee, managed with rehabilitation first (his practice website).
Treatment Options for Knee Pain Without Surgery
Mr Sivaloganathan chooses a plan from your examination, any imaging and your goals (his practice website). The options below follow the order NICE NG226 uses.
Exercise, Weight Loss and Physiotherapy
NICE recommendation 1.3.1 offers therapeutic exercise to everyone with osteoarthritis, such as muscle strengthening and aerobic fitness. Pain may rise when you start, and NICE says regular exercise still helps. For anyone carrying extra weight, NICE says any loss helps, and a 10% drop beats 5%. There is no hospital stay and no surgical risk.
Painkillers and Anti-Inflammatory Gels
NICE recommendation 1.4.2 offers an anti-inflammatory gel (a topical NSAID) for knee osteoarthritis. Anti-inflammatory tablets come next, with a medicine to protect the stomach (NHS). Asthma, a stomach ulcer, angina, or a previous heart attack or stroke can rule tablets out, according to the NHS. NICE 1.4.5 advises against routine weak opioids.
Steroid Injection
A steroid injection calms inflammation and swelling inside the joint. NICE 1.4.10 suggests it when other medicines are not helping or to support exercise, with relief for 2 to 10 weeks. It takes minutes in clinic, with ultrasound guidance if needed (his practice website). Versus Arthritis lists a pain flare in the first 24 hours, raised blood sugar and, very rarely, infection.
Hyaluronic Acid Injection
Hyaluronic acid is a gel-like lubricant, which his practice uses for stiffness from thinning cartilage. NICE recommendation 1.4.9 says not to offer these injections for osteoarthritis, so treat them as a private choice with uncertain benefit. The injection is a clinic procedure with no stay. Soreness can last a few hours to a few days (his practice website).
Platelet-Rich Plasma (PRP) Injection
Blood is taken from you and spun to concentrate the platelets, then injected into the knee (NICE HTG497). Mr Sivaloganathan gives PRP in theatre for sterile conditions (his practice website). NICE found no major safety concerns but evidence of benefit limited in quality. NICE restricts its use to special arrangements covering consent and audit.
Why Patients Choose Mr Sivaloganathan for Knee Pain Care
- Both sides of the decision: he gives injections and also performs knee replacement in London. So the right moment for surgery is discussed openly (his practice website).
- Guided injections: ultrasound guidance for steroid and hyaluronic acid injections, and PRP in an operating theatre (his practice website).
- Qualifications: Imperial College London medical graduate (degree and year [to confirm]), with an MSc from UCL whose subject was nanotechnology and regenerative medicine.
- Specialist training: orthopaedic rotations in South West London. Fellowships followed in Montreal, Canada (2021 scholarship), then with Imperial College Healthcare NHS Trust on complex knee and trauma cases using robotic assistance.
- Research: knee replacements that preserve natural alignment are the theme of his 18 PubMed-listed papers. In 2025 he joined a Visiting Surgeon Programme as faculty.
- Clinic times: Wednesday mornings at King Edward VII’s Hospital and Monday lunchtimes at Clementine Churchill Hospital, Harrow, among six London sites.
How Long Does a Knee Injection Last, and How Often Can You Have One?
This is the question most patients bring. NICE NG226 tells patients to expect a steroid to work for between 2 and 10 weeks. The NHS osteoarthritis treatment page describes relief lasting several weeks or months.
| Injection | How long relief may last | NICE position |
|---|---|---|
| Steroid | 2 to 10 weeks (NICE NG226) | Consider when other medicines do not help, or to support exercise (1.4.10) |
| Hyaluronic acid | No NICE estimate | Do not offer for osteoarthritis (1.4.9) |
| PRP | Evidence limited in quality (NICE HTG497) | Special arrangements for consent and audit only |
Versus Arthritis says doctors usually allow no more than three steroid injections into one joint within a year. Too many can damage tissue inside the joint.
Timing matters before surgery too. Versus Arthritis notes that one steroid injection can lower the body’s own hormone production for up to a month. Mr Sivaloganathan plans injections around any operation you may need.
Alternatives to Knee Injections
Injections are optional. NICE NG226 puts exercise and weight loss first, and recommends walking aids such as a stick (1.3.10). Braces and insoles are only routinely advised when the knee is unstable (1.3.11).
Some treatments are not recommended at all. NICE 1.3.8 advises against acupuncture, 1.3.9 against TENS and ultrasound therapy, and 1.4.6 against glucosamine. Versus Arthritis adds that an injection alone is unlikely to fix knee pain.
If these steps stop working and the knee limits everyday life, NICE 1.6.1 supports referral for joint replacement. That surgery is explained on the robotic-assisted partial and total knee replacement page. Keyhole washout is not one of the alternatives, as his knee arthroscopy page explains.
Your Knee Pain Pathway, Step by Step: Appointment to Injection Day
- Booking: the online form asks for brief details of your symptoms and earlier treatment (his practice website).
- Consultation: history and examination. NICE 1.1.2 says imaging is not routinely needed to diagnose osteoarthritis, so scans are booked only when they would change the plan.
- Plan: a follow-up visit goes through results and options, with a written report of the diagnosis and recommendations (his practice website).
- Before an injection: blood pressure and blood sugar may be checked before a first steroid injection, and blood-thinning medicines may need a blood test (Versus Arthritis).
- Injection day: steroid or hyaluronic acid in clinic, often with ultrasound. PRP is given in theatre. You can walk on the knee straight away (his practice website).
- Review: a follow-up appointment checks progress and agrees next steps, including exercise (his practice website).
Recovery and Risks After Knee Injections
You can put full weight on the leg immediately after any of these injections (his practice website). Mild discomfort lasts a few hours, sometimes a few days. After a steroid injection, Versus Arthritis advises not overdoing exercise for 2 weeks.
| Treatment | Hospital stay | Example risk |
|---|---|---|
| Steroid injection | None, clinic procedure (his practice website) | Pain flare in the first 24 hours, settling within a couple of days (Versus Arthritis) |
| Steroid injection with diabetes | None | Blood sugar raised for a few days (Versus Arthritis) |
| Hyaluronic acid injection | None (his practice website) | Soreness for hours to a few days (his practice website) |
| PRP injection | Given in theatre (his practice website) | No major safety concerns, benefit uncertain (NICE HTG497) |
| Anti-inflammatory tablets | None | Stomach lining damage, so a protecting medicine is added (NHS) |
Versus Arthritis notes that steroid injections can occasionally thin or lighten the skin where the needle went in. If the joint becomes hotter and more painful afterwards, especially if you feel unwell, see a doctor straight away.

FAQs About Knee Pain Management and Injections
Is a knee injection a major procedure?
No. A steroid or hyaluronic acid injection takes minutes in clinic. PRP is given in theatre, but it is still an injection rather than surgery (his practice website).
How quickly will I recover after a knee injection?
You can walk on the knee straight away, with mild soreness for hours or a few days (his practice website). Versus Arthritis suggests easing off hard exercise for 2 weeks after a steroid injection.
Can I drive myself home after an injection?
Local anaesthetic given with a steroid can leave numbness for up to 24 hours (Versus Arthritis). Bring someone to drive if the knee feels numb or weak.
Will my knee pain come back after a steroid injection?
Usually, in time. NICE NG226 puts the relief at 2 to 10 weeks, which is why exercise continues alongside it.
What are the alternatives to having injections?
Exercise, weight loss, an anti-inflammatory gel and a walking stick, all recommended in NICE NG226. Knee replacement comes later, when these no longer help.
How much do private knee injections cost?
His fees are not published. The cost depends on the injection type, and PRP needs a theatre session.
Why won't the NHS offer hyaluronic acid injections?
NICE recommendation 1.4.9 advises against them for osteoarthritis after reviewing the evidence on benefit and cost. They remain a private option.
Is there good evidence for PRP in the knee?
Not yet. NICE HTG497 (2019) found no major safety concerns but evidence of benefit limited in quality. It asks for more trials.
How many steroid injections can I have in a year?
Usually no more than three into the same knee within 12 months, according to Versus Arthritis.
Can I have a steroid injection if I have diabetes?
Yes, with care. Versus Arthritis says blood sugar can rise for a few days afterwards, so monitor it closely.
When should I think about a knee replacement instead?
Once the knee is limiting everyday life and exercise, weight loss and medicines have stopped helping, NICE 1.6.1 supports a surgical referral. Age and weight alone should not rule you out (NICE 1.6.3).
