Alternatives to Knee Replacement: What Works, What Doesn't, and When Surgery Is the Answer (2026)
The main alternatives to a knee replacement are therapeutic exercise and, if you are overweight, weight loss — NICE calls these the core treatments for osteoarthritis. Anti-inflammatory gels, tablets and steroid injections can ease pain alongside them; steroid injections help for only 2 to 10 weeks. NICE advises against hyaluronic acid injections, glucosamine, acupuncture and keyhole 'washout' surgery. When pain still limits your life despite these, NICE says referral for joint replacement should be considered.
Key facts
- NICE's core treatments for osteoarthritis are therapeutic exercise and weight management, with information and support (NICE guideline NG226).
- Losing 10% of body weight is likely to help more than 5%, but any weight loss is likely to be beneficial (NICE).
- For knee osteoarthritis NICE recommends a topical anti-inflammatory (NSAID) gel first; steroid injections give only short-term relief of 2 to 10 weeks.
- NICE says do not offer hyaluronan injections, glucosamine, strong opioids, acupuncture, or arthroscopic lavage and debridement for osteoarthritis.
- NICE says people should not be excluded from referral for joint replacement because of age, smoking, other conditions or BMI.

What NICE recommends before surgery
NICE, which sets the standards for NHS care in England, published its guideline on osteoarthritis in 2022 (NG226). It puts the alternatives to surgery in a clear order.
| Treatment | What NICE says |
|---|---|
| Therapeutic exercise | Offer to everyone: strengthening and general fitness, tailored to you. Pain may rise at first; regular exercise still helps. |
| Weight loss | If you are overweight: any loss helps, 10% of body weight is likely better than 5%. |
| Topical NSAID gel | Offer for knee osteoarthritis. |
| Oral NSAID tablets | Consider if gels don't work or don't suit you, taking account of side effects. |
| Steroid injection into the joint | Consider when other medicines don't work or to support exercise; relief lasts 2 to 10 weeks. |
| Walking aids and braces | Consider if exercise alone isn't enough without them. |

What NICE says not to use
Several popular treatments did not show enough benefit for NICE to recommend them:
- Hyaluronic acid ('gel' or 'lubricant') injections — "do not offer".
- Glucosamine — "no strong evidence of benefit".
- Paracetamol and weak opioids — not routinely; NICE says there is "no strong evidence of benefit" for paracetamol.
- Strong opioids — the risks outweigh the benefits.
- Acupuncture and dry needling — "do not offer".
- Keyhole washout surgery (arthroscopic lavage or debridement) for arthritis — "do not offer". Knee arthroscopy still has a place for other problems, such as some meniscus tears; see knee arthroscopy.
Some private clinics sell these treatments. If you are offered one, ask what evidence supports it for your condition and what it will cost over a year.
Partial knee replacement: the smaller operation
If arthritis affects only one part of the knee, a partial (unicompartmental) knee replacement may be possible instead of a total one. It replaces only the worn compartment. Whether it suits you depends on the pattern of damage and the state of your ligaments, which a surgeon assesses on X-ray and examination.
Our guide to partial vs total knee replacement compares the two. At OrthoVoyage's partner hospital in Poland a partial knee replacement costs €7,570 (about £6,520), against roughly £12,300–£14,800 self-pay in the UK.
When the alternatives have stopped working
NICE says referral for joint replacement should be considered when your symptoms — pain, stiffness, reduced function — substantially affect your quality of life and non-surgical treatment hasn't worked or isn't suitable. It also says you should not be excluded from referral because of your age, sex, smoking, other health conditions or your weight.
Once you are referred, the choice is about time and money:
- The NHS. Free, but trauma and orthopaedics has the longest list of any specialty: 843,419 people waiting at the end of August 2026, and only 61.1% within 18 weeks. Check the wait at your own hospital.
- A UK private hospital. Published self-pay prices for a total knee replacement run from £13,020 to £16,914. UK knee replacement prices.
- Poland. At OrthoVoyage's partner hospital a total knee replacement is from €8,620 (about £7,420), with the implant, three days in hospital and up to seven physiotherapy sessions included. Knee replacement in Poland.
Frequently asked questions
What is the best alternative to a knee replacement?
NICE's core treatments are therapeutic exercise and, if you are overweight, weight loss, with pain relief such as anti-inflammatory gel alongside them. They are the first step for everyone with knee osteoarthritis. This is general information from NICE guideline NG226, not medical advice.
Do knee injections work instead of surgery?
Steroid injections can ease pain, but NICE says the relief is short-term, 2 to 10 weeks. NICE advises against hyaluronic acid injections for osteoarthritis.
Can I be refused a knee replacement because of my weight?
NICE says people should not be excluded from referral for joint replacement because of overweight or obesity based on measures such as BMI, nor because of age, smoking or other conditions. Your surgeon should explain how these factors affect your risks.
When should I consider a knee replacement?
NICE says to consider referral when knee symptoms substantially affect your quality of life and non-surgical treatment has not worked or is not suitable. Your GP makes the referral.
