Joint Replacement Rehabilitation

Support for movement, strength and recovery after joint replacement

Joint replacement surgery can improve mobility and reduce the impact of long-term joint problems, but recovery does not end when you leave hospital.

After surgery, it is common to experience weakness, stiffness, swelling and reduced confidence in the operated joint. Everyday activities such as walking, using stairs, getting out of a chair or lifting the arm may initially feel more difficult.

Joint replacement rehabilitation focuses on gradually restoring movement, rebuilding strength and helping you return to everyday activities safely and confidently.

What is joint replacement rehabilitation?

Joint replacement rehabilitation is a structured physiotherapy programme following surgery to replace a damaged joint.

It may be required after:

• Hip replacement
• Knee replacement
• Shoulder replacement
• Partial joint replacement
• Revision joint replacement surgery

The rehabilitation programme depends on which joint has been replaced, the surgical procedure, your general health and how you are progressing after surgery.

Early treatment may focus on basic movement and mobility. As recovery continues, exercises can become more challenging and more closely related to your normal activities.

When rehabilitation may help

Physiotherapy after joint replacement may help with:

• Joint stiffness
• Reduced movement
• Muscle weakness
• Difficulty walking
• Difficulty using stairs
• Reduced balance
• Swelling
• Difficulty getting up from a chair
• Reduced confidence using the operated joint
• Difficulty returning to work
• Reduced physical fitness after surgery
• Difficulty returning to exercise
• Ongoing functional limitations after the initial recovery period

The aim is not simply to complete a standard set of exercises. Rehabilitation should reflect what you need the replaced joint to do in everyday life.

What happens during your first appointment?

Your physiotherapy assessment will consider your surgery, current stage of recovery and any guidance provided by your orthopaedic team.

The physiotherapist may ask about:

• The type and date of your joint replacement
• Your recovery since surgery
• Current pain and swelling
• Medication
• Walking ability
• Use of crutches, sticks or other aids
• Joint movement
• Activities you currently find difficult
• Stairs
• Sleep
• Work and exercise
• Other medical conditions
• Your rehabilitation goals

The physical assessment may include:

• Joint movement
• Muscle strength
• Walking
• Balance
• Sit-to-stand movement
• Stairs
• Swelling
• Everyday functional movements

This helps establish an appropriate starting point for your rehabilitation programme.

What rehabilitation may include

Treatment changes as the joint heals and your physical ability improves.

Movement exercises

Joint stiffness is common after replacement surgery.

Exercises may be used to gradually improve movement while following any restrictions provided by your surgical team.

Regular movement can also help you become more comfortable using the operated joint during everyday activities.

Strengthening

Muscles around the replaced joint often become weaker before and after surgery.

Strengthening exercises may initially be simple and controlled before gradually progressing towards more demanding movements.

The programme may focus on:

• Leg strength after hip or knee replacement
• Shoulder and arm strength after shoulder replacement
• Core and trunk control
• General whole-body strength

Walking rehabilitation

Following hip or knee replacement, you may initially walk with crutches, sticks or another aid.

Physiotherapy can help with:

• Weight-bearing
• Step pattern
• Walking confidence
• Gradually increasing distance
• Using walking aids correctly
• Reducing reliance on an aid when appropriate
• Returning towards normal everyday walking

Balance exercises

Reduced strength and confidence after surgery can affect balance.

Exercises may include standing, stepping, turning and other movements required during daily life.

Home exercise programme

Exercises completed between appointments are an important part of rehabilitation.

Your programme can be changed as your movement and strength improve so that you continue progressing rather than repeating the same early exercises throughout recovery.

Hip replacement rehabilitation

After hip replacement, early rehabilitation often focuses on walking safely and rebuilding strength around the hip and leg.

You may initially notice difficulty with:

• Walking
• Getting out of a chair
• Getting into or out of bed
• Using stairs
• Putting weight through the operated leg
• Getting in and out of a car
• Longer periods of standing

Rehabilitation may include:

• Hip and leg strengthening
• Walking practice
• Balance exercises
• Sit-to-stand exercises
• Stair practice
• Gradually increasing walking distance
• Returning to normal everyday activities

Any precautions provided by your surgical team should be followed during the early stages of recovery.

Knee replacement rehabilitation

Knee replacement can initially cause stiffness, swelling and weakness around the thigh and lower leg.

Rehabilitation commonly focuses on restoring useful knee movement while rebuilding the strength required for walking and everyday tasks.

Treatment may include:

• Knee bending and straightening exercises
• Thigh strengthening
• Calf and leg exercises
• Walking
• Balance work
• Sit-to-stand exercises
• Step exercises
• Stair practice

As recovery progresses, exercises can become more challenging and may include squatting, cycling, gym exercises or other activities relevant to your goals.

Shoulder replacement rehabilitation

Shoulder replacement rehabilitation follows a different approach from hip and knee rehabilitation because the operated shoulder may need to be protected during the early healing period.

Depending on the procedure, early rehabilitation may focus on controlled movement within the range recommended by the surgical team.

Later rehabilitation may include:

• Improving shoulder movement
• Rebuilding muscle strength
• Improving shoulder control
• Reaching
• Lifting
• Carrying
• Returning to household activities
• Returning to work or recreational activity

Progression depends heavily on the type of shoulder replacement and the instructions provided by your surgeon.

Walking after hip or knee replacement

Walking usually improves gradually rather than immediately returning to your previous pattern.

Initially, you may:

• Walk more slowly
• Take shorter steps
• Rely on crutches or sticks
• Feel less confident on the operated side
• Become tired more quickly

Physiotherapy can help you gradually increase how much weight you place through the leg and improve your walking pattern.

As strength and confidence improve, walking distance and speed can be increased.

Using crutches or walking sticks

Walking aids provide support while strength, balance and confidence recover.

Your physiotherapist can help you understand:

• How to use the aid correctly
• How much weight to place through the operated leg
• How to manage stairs
• When additional support is still useful
• When it may be appropriate to reduce reliance on the aid

There is no benefit in stopping an aid too early if it causes you to walk poorly or feel unsafe.

Equally, once you have enough strength and balance, rehabilitation can help you gradually become less dependent on it.

Managing stairs

Stairs can be difficult during the early stages of recovery after hip or knee replacement.

Rehabilitation may include:

• Leg strengthening
• Step exercises
• Balance
• Using a handrail
• Practising the safest stair technique
• Gradually returning towards a normal stair pattern

The aim may initially be simply to manage stairs safely before progressing towards greater strength and confidence.

Getting up from a chair

Standing from a chair requires useful hip and knee movement as well as leg strength.

Following joint replacement, you may initially rely more heavily on your arms or the unoperated leg.

Treatment may include:

• Adjusting foot position
• Practising forward weight shift
• Strengthening the legs
• Repeated sit-to-stand exercises
• Gradually reducing reliance on the arms

This movement is particularly useful because it directly relates to everyday independence.

Managing swelling

Swelling is common after joint replacement and may continue for some time during recovery.

It can make the joint feel stiff and may temporarily affect movement.

Depending on your individual situation, management may include:

• Regular movement
• Appropriate exercise
• Elevation
• Gradual increases in activity
• Following any swelling-management advice provided by your surgical team

A sudden or significant increase in swelling should not simply be assumed to be part of normal recovery and may require medical review.

Rebuilding strength after surgery

Joint problems often reduce activity before surgery, which means muscle weakness may already be present before the replacement takes place.

Surgery and the recovery period can cause further temporary loss of strength.

Rehabilitation therefore needs to build strength gradually.

Exercises may progress from:

• Simple seated or lying exercises
• Standing exercises
• Sit-to-stands
• Step exercises
• Resistance bands
• Weights or gym equipment
• More demanding functional movements

The goal is to build enough strength for the activities you want to return to.

Building walking distance

Your first walks after surgery may be relatively short.

Rather than trying to immediately reach your previous walking distance, rehabilitation may gradually increase:

• Time spent walking
• Distance
• Walking speed
• Frequency
• Outdoor walking
• Uneven surfaces
• Gentle slopes

Small, regular increases can help build endurance while allowing the operated joint and surrounding muscles to adapt.

Returning to everyday activities

Successful rehabilitation should make daily life easier, not simply improve exercise performance.

Your programme may work towards activities such as:

• Walking around the home
• Shopping
• Cooking
• Using stairs
• Getting in and out of a car
• Household tasks
• Caring for family members
• Walking outdoors
• Gardening
• Social activities

The exercises used during treatment can become more specific to these activities as your recovery progresses.

Returning to work

The appropriate time to return to work depends on the joint replaced, your recovery and the demands of your job.

A desk-based role may require you to tolerate sitting, walking and travelling.

A more physical job may involve:

• Prolonged standing
• Lifting
• Carrying
• Stairs
• Repeated walking
• Squatting
• Reaching overhead

Rehabilitation can gradually prepare you for these demands.

A phased return or temporary change in duties may sometimes be appropriate.

Returning to driving

Returning to driving depends on several factors, including:

• Which joint was replaced
• Your movement
• Strength
• Ability to control the vehicle
• Whether you are still using certain medication
• Guidance from your surgeon
• Relevant driving requirements

You need to be able to control the vehicle safely and respond appropriately in an emergency.

Follow the advice provided by your surgical and medical team rather than returning based on time alone.

Returning to exercise

As strength and mobility improve, rehabilitation may progress towards recreational exercise.

Depending on the joint replaced and medical guidance, this may include:

• Walking
• Cycling
• Swimming
• Gym training
• Exercise classes
• Low-impact recreational activity

The appropriate activities will depend on the type of replacement and your previous level of exercise.

You do not need to return to every activity at once. Exercise can be introduced gradually as your body adapts.

Returning to the gym

Gym-based rehabilitation can be useful for rebuilding strength once you are ready for more challenging exercise.

Depending on the joint involved, your programme may include:

• Leg press
• Squats or supported squats
• Step exercises
• Cycling
• Upper-body strengthening
• Resistance machines
• Free weights
• Cardiovascular exercise

The amount of resistance should increase gradually.

Good control and consistency are generally more useful than trying to return immediately to the weights you used before surgery.

Confidence after joint replacement

Even when the replaced joint is healing well, you may initially feel cautious about using it.

You may worry about:

• Putting weight through the joint
• Bending
• Using stairs
• Falling
• Lifting
• Exercising
• Damaging the replacement

Rehabilitation gradually exposes you to these activities at an appropriate stage.

Confidence often improves as movement becomes easier and you experience what the joint is able to manage.

Rehabilitation progresses in stages

Joint replacement rehabilitation changes throughout recovery.

The process may broadly include:

Early recovery

The initial focus may be on:

• Safe movement
• Walking
• Managing everyday activities
• Basic exercises
• Maintaining joint movement

Building movement and strength

As healing progresses, treatment may focus more on:

• Increasing joint movement
• Strengthening
• Improving balance
• Walking further
• Managing stairs

Returning to normal activity

Later rehabilitation may focus on:

• Work
• Longer walks
• Gym exercise
• Hobbies
• More demanding everyday activities

Not everyone progresses at the same rate, and rehabilitation should be based on your individual recovery.

Preparing before joint replacement

Rehabilitation can sometimes begin before planned hip or knee replacement surgery.

This may include:

• Maintaining leg strength
• Keeping physically active within your limits
• Practising exercises that may be used after surgery
• Preparing for walking with an aid
• Understanding what the early recovery period may involve
• Preparing your home for reduced mobility

The aim is not to eliminate the need for rehabilitation after surgery, but to help you enter the recovery period as prepared as possible.

Following your surgeon’s guidance

Different joint replacements and surgical techniques can involve different precautions.

Your surgical team may provide guidance about:

• Weight-bearing
• Joint movement
• Lifting
• Sleeping positions
• Use of a sling or walking aid
• Driving
• Returning to work
• Exercise

Your physiotherapy programme should work within this guidance.

If your surgeon changes your restrictions during a follow-up appointment, your rehabilitation can be updated accordingly.

When further medical assessment may be needed

Some symptoms following joint replacement require medical review rather than simply adjusting your exercises.

Seek appropriate medical advice if you experience:

• A sudden significant increase in pain
• Rapid or unusual swelling
• Increasing redness or heat around the wound
• Wound discharge
• Fever or feeling significantly unwell
• Sudden difficulty putting weight through the leg
• New significant weakness or numbness
• Sudden calf pain or swelling
• New chest pain
• Unexplained shortness of breath
• A fall or injury involving the replaced joint

Follow any specific warning signs and instructions provided by your hospital or surgical team.

Treatment based on your goals

The goal of rehabilitation is different for every person.

You may want to:

• Walk without an aid
• Use stairs confidently
• Return to work
• Walk further outdoors
• Drive again
• Return to the gym
• Manage household activities
• Return to hobbies
• Improve strength
• Feel more confident using the replaced joint

Your programme can be developed around these goals and adjusted as your recovery progresses.

How long does joint replacement rehabilitation take?

Recovery varies depending on the joint replaced, the type of surgery and your individual health and physical ability.

Some improvements may happen relatively early, while strength, mobility and confidence can continue developing over several months.

Factors that may affect recovery include:

• Your physical ability before surgery
• The type of replacement
• Muscle strength
• Other health conditions
• Complications
• How regularly rehabilitation exercises are completed
• The level of activity you want to return to

Your progress can be reviewed throughout rehabilitation rather than relying on one fixed recovery timeline.
