Alternatives to Knee Replacement: What to Try First

The main alternatives to a knee replacement are non-surgical: physiotherapy and exercise, weight loss, pain-relief medication, walking aids, bracing, and steroid injections, with osteotomy as a surgical option for selected patients. These manage symptoms and can delay or avoid surgery, especially in earlier arthritis, but they do not reverse the underlying wear¹. When knee pain limits your daily life despite a real trial of them, a replacement is usually the next step.

I delayed my own surgery for years, and the alternatives genuinely helped me hold on, right up until they did not. This guide, checked by a consultant orthopaedic surgeon, sets out each option honestly: what it does, how well it works, and where its limits are. If you are weighing whether surgery is due, read it alongside signs you need a knee replacement and the pillar, knee replacement surgery.

Exercise and physiotherapy

Exercise and physiotherapy are the foundation, and NICE recommends them for everyone with knee osteoarthritis as the core treatment². Strengthening the muscles around the knee, particularly the thigh muscles, supports the joint, improves function, and reduces pain. A physiotherapist can build a programme suited to you. It will not undo the arthritis, but it is the single most evidence-backed non-surgical measure, and it also leaves you fitter and stronger if you do eventually need surgery, which helps recovery.

Weight loss

Losing excess weight reduces the load on the knee with every step and can meaningfully reduce pain and slow wear. It is recommended, alongside exercise, for everyone with knee osteoarthritis². The load through the knee is several times your body weight when you walk and climb stairs, so even modest weight loss changes the forces going through a worn joint. As with exercise, it has the dual benefit of improving your fitness for surgery should you need it.

Pain relief, walking aids, and bracing

Pain-relief medication, walking aids, and bracing manage symptoms day to day. Pain relief ranges from simple painkillers and topical anti-inflammatory gels to medication your doctor prescribes; supportive footwear, a walking stick, and sometimes a knee brace or support can offload the joint and steady it. None of these treats the arthritis itself, but together they can keep you mobile and comfortable enough to put off surgery. The honest limit is that as arthritis advances, the same measures do less. A stick got me through my last couple of years; eventually it was not enough.

Steroid injections

A steroid (corticosteroid) injection can reduce pain and inflammation for a period of weeks to months. It can be useful for a flare-up or to get you through a particular event, but it does not change the underlying arthritis, the benefit is temporary, and the number of injections is usually limited¹. It is a way to buy time and comfort, not a cure, and it is best thought of as one tool among several rather than a substitute for exercise and weight management.

Osteotomy

An osteotomy is a surgical alternative that realigns the bone to shift weight off the worn side of the knee. The surgeon cuts and repositions the shin or thigh bone so that load passes through the healthier side of the joint. It can delay or avoid a replacement in selected younger, active patients whose arthritis is confined to one compartment and who have alignment that can be corrected. It is not for everyone, and it is a recovery in its own right, but for the right person it can preserve their own knee for years.

When alternatives are no longer enough

Alternatives manage symptoms and buy time; they do not reverse arthritis, so there usually comes a point where they are no longer enough. That point is when knee pain and loss of function limit your daily life and quality of life despite a genuine trial of non-surgical options. Surgery is usually offered once these have been tried³. Be clear-eyed about what comes next: a knee replacement is a successful operation, but with around 80 to 90% of people satisfied it has honestly lower satisfaction than a hip, and about 1 in 5 feel the knee is never quite normal⁴. The choice between carrying on with alternatives and moving to surgery is best made with your surgeon, weighing how much the knee limits you against the demanding recovery.
