Osteoarthritis is a common cause of knee pain, particularly from midlife onwards, but pain severity does not always match an X-ray result. Some people have marked changes on imaging and manageable symptoms; others have early changes but significant pain, swelling or loss of confidence in the knee. A focused assessment helps separate osteoarthritis from problems such as a meniscal injury, tendon pain, bursitis or referred pain from the hip or spine.
Knee osteoarthritis: what are my treatment options?
For most people, treatment starts with a non-surgical plan aimed at reducing pain, improving movement and keeping the knee strong. Surgery is not inevitable, and it is usually considered only when well-delivered conservative treatment no longer provides enough relief for day-to-day life.
The most effective plan is personalised. Someone who wants to return to running has different priorities from someone whose main aim is getting around Leeds comfortably, managing stairs at home or sleeping without pain. Your clinician should explain what is likely to help, how quickly it may work and where the limitations are.
Start with an accurate assessment
A specialist assessment should look beyond the label of “wear and tear”. Your clinician will ask when the pain occurs, whether the knee locks or gives way, where swelling develops and how symptoms affect work, sport and mobility. They will assess your range of movement, joint stability, muscle strength and tenderness around the knee.
Knee osteoarthritis can often be diagnosed clinically. An X-ray may be helpful where the diagnosis is uncertain, symptoms are more advanced or surgical options need to be considered. Diagnostic ultrasound does not show arthritis like an X-ray or MRI, but it can be valuable for identifying fluid in the joint, Joint line changes, cysts, tendon problems and other soft-tissue causes of pain. It can also guide an injection precisely when this is appropriate.
Exercise and physiotherapy: The foundation of care
Movement can feel counterintuitive when your knee hurts, but targeted exercise is one of the most reliable treatments for osteoarthritis. The aim is not to push through severe pain. It is to improve the strength and control of the muscles that support the knee, particularly the quadriceps, hamstrings and gluteal muscles.
A physiotherapy programme may include strengthening work, balance exercises, mobility drills and a gradual return to activities that matter to you. Cycling, swimming, walking in manageable amounts and low-impact gym work can all be useful, depending on your starting point. The best exercise is usually one you can perform consistently without causing a substantial flare that lasts for days.
Progress can be gradual. Many people need several weeks of regular work before they notice meaningful improvement, and short-term discomfort when starting a programme does not necessarily mean harm. However, a sudden increase in swelling, sharp pain, a locked knee or an inability to bear weight deserves clinical review.
Weight management and practical changes
If you are carrying extra weight, even a modest reduction can reduce load through the knee and improve symptoms. This is not about blame, and it is not a requirement for receiving treatment. It is one potentially helpful part of a wider plan, particularly where pain limits activity and creates a difficult cycle of reduced fitness and worsening mobility.
Simple adjustments can also make a difference. Supportive footwear, pacing longer walks, using a handrail on stairs and temporarily adapting high-impact activity may reduce flare-ups. A walking stick can help some people with more significant pain, particularly when used in the hand opposite the affected knee. Braces are useful for selected patients, especially if one side of the knee is more affected, but they are not a universal solution and should be chosen carefully.
Medicines for knee osteoarthritis pain
Pain relief should support movement and rehabilitation, rather than replace them. Topical anti-inflammatory gels are often a sensible first option because they act locally and generally have fewer systemic effects than tablets. Paracetamol may help some people, although its effect on osteoarthritis pain is often limited.
Anti-inflammatory tablets can be effective during a flare, but they are not suitable for everyone. Your clinician will consider stomach, kidney and heart risks, as well as conditions such as asthma and any medicines you already take. They may recommend the lowest effective dose for the shortest practical period. Strong opioid painkillers are generally avoided for long-term osteoarthritis because their risks often outweigh the benefit.
Supplements are frequently marketed for joint health, but evidence for products such as glucosamine is inconsistent. It is worth discussing any supplement you are considering, particularly if you take regular medication.
When can injections help?
An injection may be considered when pain and swelling are preventing rehabilitation or when simpler measures have not provided enough relief. It is not a cure for osteoarthritis, but it can be a useful window of symptom control that allows you to build strength and restore function.
A corticosteroid injection can reduce inflammation and pain in some people, especially where there is an active flare with swelling. Relief varies ranging from weeks to a number of months, repeated steroid injections are not appropriate indefinitely and should be used sensibly.
Hyaluronic acid injections are offered in some settings, they have a safe injection profile without the potential associated risk of steroid injections and can provide very good pain relief for patient with mild-moderate osteoarthritis. Platelet-rich plasma, or PRP, is also sometimes discussed. Research is evolving, yet benefits remain less predictable than marketing can suggest. Finally Arthrosamid is a non-biodegradable hydrogel implant that integrates into the lining of the knee joint (the synovium). It can help reduce pain and stiffness and improve joint function with evidence showing efficacy at 5 years. However, not every patient is a suitable candidate. (Please see our Arthrosamid blog for more information). A good consultation should be clear about the evidence, cost and likely outcome rather than presenting any injection as a guaranteed fix.
Where an injection is selected, ultrasound guidance can improve placement accuracy, particularly if fluid needs to be drained or the anatomy is less straightforward. At Clinic 360, assessment, diagnostic ultrasound and ultrasound-guided intervention can be coordinated in one appointment where clinically appropriate, providing a clear documented plan without unnecessary delay.
When should surgery be considered?
Surgical opinion may be appropriate if knee pain remains severe despite a structured non-surgical programme, significantly affects sleep or independence, or prevents you from doing the activities that matter most. A knee replacement can be very effective for the right patient with advanced osteoarthritis, but it is major surgery with recovery time and no procedure is risk-free.
Arthroscopy, often called keyhole surgery, is not usually recommended for osteoarthritis alone. It may have a role in specific situations, such as a truly locked knee caused by a separate mechanical problem, but it is not a routine answer to degenerative knee pain. An orthopaedic consultation can help determine whether surgery is likely to offer a worthwhile improvement.
A plan that fits your life
For ongoing knee pain, the goal is practical: understand what is driving your symptoms, control the factors that can be changed and choose treatment that gets you moving with more confidence. Rapid access to specialist assessment can replace uncertainty with a plan that is specific to your knee, your schedule and the life you want to get back to.
