Physiotherapy after knee replacement is one of the most important parts of your recovery. The right exercises, started at the right time, help you regain strength, range of movement, and confidence in your new knee. Yet many patients are surprised by how much the physiotherapy experience varies depending on whether you go NHS or private.
This guide explains what physiotherapy after knee replacement looks like in the UK in 2026. We cover how many sessions you may need, what it costs privately, and what exercises to do at each stage.
Your complete guide to physiotherapy after knee replacement – what to expect at each stage, exercises, and NHS vs private options.
Your new knee joint gives you the hardware. Physiotherapy gives you the ability to use it properly. Without structured rehabilitation, you risk stiffness, muscle weakness, and a slower return to daily life.
Research consistently shows that patients who follow a physiotherapy programme after knee replacement recover faster. They report less pain, better mobility, and greater confidence at the six-week and three-month marks.
Regaining full range of movement is especially important after knee replacement. Unlike hip replacement, where most patients achieve good mobility quickly, knee replacement requires dedicated work to bend and straighten the joint fully. This is where physiotherapy makes the biggest difference.
Early mobilisation reduces the risk of blood clots, chest infections, and muscle wasting. Your physiotherapy starts in hospital, on the same day as your operation.
This short video covers everything you need to know about physiotherapy after knee replacement in the UK in 2026. You will learn what rehab to expect on the NHS, how private physiotherapy compares in cost and access, the key exercises at each stage of recovery, and how to get the best possible outcome from your new knee.

NHS physiotherapy after knee replacement typically begins on the ward. A physiotherapist will visit you on the day of surgery or the following morning. They will help you stand, take your first steps with a walking frame, and begin basic exercises.
Most NHS hospitals aim to see you once or twice a day during your stay. You will practise getting in and out of bed, walking short distances, and bending your knee. The hospital stay is usually two to three nights.
Before you leave, your physiotherapist will give you an exercise sheet. This is your home programme for the first six weeks. The exercises focus on straight leg raises, knee bends, ankle pumps, and gentle walking.
This is where NHS provision varies significantly. Some hospital trusts offer outpatient physiotherapy classes or one-to-one sessions after discharge. Others provide only a leaflet and a telephone helpline.
A number of NHS trusts run circuit-based rehabilitation classes at six to eight weeks after surgery. These group sessions focus on strength, balance, and range of movement. However, not all trusts offer them.
If your consultant feels you need extra support at your follow-up appointment, they can refer you for outpatient physiotherapy. But this is not automatic. Waiting times for NHS physiotherapy can be several weeks.
The reality is that many NHS patients manage their physiotherapy after knee replacement largely on their own, following the exercise sheet from discharge.
If you want guaranteed, regular access to a physiotherapist, private treatment removes the uncertainty. Here is what to budget in 2026.
| Location | Typical Cost Per Session |
|---|---|
| London | £60 – £100 |
| Other major cities | £45 – £75 |
| Smaller towns and rural areas | £35 – £60 |
Â
Sessions typically last 30 to 60 minutes. The first appointment is often longer and may cost more, as it includes a full assessment.
Most patients benefit from eight to twelve physiotherapy sessions over the first three months after knee replacement. Knee replacement often requires more rehabilitation than hip replacement because regaining full bend is harder.
A typical pattern is weekly sessions for the first six weeks, then fortnightly as you become more independent. Some patients need fewer sessions; others benefit from more.
At £50 to £75 per session, a course of ten sessions costs approximately £500 to £750. This is a worthwhile investment in your recovery.
If you have private medical insurance, your policy may cover post-operative physiotherapy. Check your policy for session limits, excess payments, and whether your physiotherapist must be on the approved list.
Some insurers cover a fixed number of sessions as part of the surgical authorisation. Others require a separate referral.
Private knee replacement packages usually include some physiotherapy, but the amount varies by provider. Check exactly what is covered before you commit.
Most fixed-price packages include physiotherapy during your hospital stay. This is typically one or two sessions per day for two to four nights. You will also receive a structured home exercise programme.
Many packages include one follow-up physiotherapy appointment at two weeks after surgery. Some providers include a second follow-up at six weeks.
Additional outpatient sessions beyond the initial follow-ups are not always covered. If you need ongoing rehabilitation, you may need to pay for private physiotherapy separately.
Pre-operative physiotherapy (prehab) is also rarely included. However, evidence suggests that patients who strengthen their leg muscles before surgery recover more quickly afterwards.

Your physiotherapist will give you a tailored programme. Most knee replacement recovery plans follow a similar structure. Here is what to expect at each stage.
The focus is on reducing swelling, preventing stiffness, and basic mobility. Exercises include ankle pumps, static quadriceps contractions, straight leg raises, and gentle knee bends while lying down. You should aim for these exercises three to four times a day.
Walking with a frame is important. Keep walks short but frequent. Ice the knee for 15 to 20 minutes after exercises to manage swelling.
As healing progresses, exercises become more demanding. You will work on seated knee bends, standing knee straightening, step-ups onto a low step, and wall squats. Walking distances increase, now with crutches.
The key goal in this phase is regaining at least 90 degrees of knee bend. Most daily activities require 90 degrees or more. Your physiotherapist will measure your progress at each session.
The goal now is to restore full strength and confidence. Exercises include deeper squats, single-leg balance work, resistance band exercises, and walking on varied surfaces. Stair climbing should become more comfortable.
Most people return to driving at around six weeks. By three months, you should be able to walk comfortably for 30 minutes or more without significant pain.
Physiotherapy after knee replacement does not stop at three months. Continuing regular exercise supports the long-term health of your joint. Swimming, cycling, and walking are all excellent for maintaining strength and flexibility.
Your knee can continue to improve for up to two years after surgery. Many patients find that they feel stronger and more mobile at 12 months than at three months.

Physiotherapy begins on the day of surgery or the day after. In hospital, a physiotherapist will help you stand, take your first steps, and begin gentle exercises. Early movement is essential for preventing blood clots, reducing stiffness, and starting your recovery. Most patients begin a structured outpatient physio programme within one to two weeks of discharge.
With consistent physiotherapy, most people regain functional mobility within six to twelve weeks. You should be able to walk comfortably without a stick by around six weeks and return to most daily activities by three months. Full recovery – including strength, balance, and confidence – typically takes six to twelve months. Continuing exercises beyond formal physio sessions is important.
NHS physiotherapy provision varies by area. Some trusts offer six to eight face-to-face sessions, others provide group classes, telephone follow-ups, or digital physio programmes. In some areas, you may receive as few as two to three sessions. Ask your hospital before surgery what outpatient physio support is included and plan for private top-up sessions if needed.
Some discomfort during physiotherapy is normal, especially in the first few weeks when you are working to regain your range of movement. Your physiotherapist will push you to progress but should never cause sharp or severe pain. Ice packs after sessions, prescribed painkillers taken before appointments, and gentle warm-up exercises can all help manage discomfort.
In the first two weeks, you will focus on ankle pumps, static quadriceps contractions, heel slides, and gentle knee bending. By weeks three to six, you progress to standing exercises, mini squats, step-ups, and stationary cycling. From six weeks onwards, you add balance work, resistance exercises, and longer walks. Your physiotherapist will tailor the programme to your progress.
