A total knee replacement (TKR) can significantly improve mobility and quality of life for people experiencing severe knee
arthritis and
chronic knee pain. However, surgery is only the beginning of the recovery process. Post-surgical physiotherapy plays an important role in restoring knee movement, strength, balance, walking ability, and confidence.
At
Townline Physiotherapy Abbotsford, we help patients safely progress through their rehabilitation after total knee replacement with individualized physiotherapy programs based on their surgery, medical history, mobility, and recovery goals.
Important disclaimer: The exercises and information in this article are for general education only. Do not begin or progress these exercises without first being assessed and cleared by your physiotherapist and surgical team. Your exercises, intensity, walking program, and precautions should be individualized based on your surgery and recovery.
Why Is Physiotherapy Important After Knee Replacement?
After total knee replacement, it is common to experience:
- Knee swelling
- Pain and stiffness
- Reduced range of motion
- Weak quadriceps muscles
- Difficulty walking
- Difficulty going up and down stairs
- Reduced balance
- Muscle fatigue
- Fear of putting weight through the operated leg
Physiotherapy helps gradually restore these abilities while monitoring your recovery.
The goals of rehabilitation commonly include:
- Improving knee bending and straightening
- Reducing swelling
- Restoring leg strength
- Improving walking
- Improving balance
- Increasing independence with daily activities
- Returning to normal activities safely
Early Exercises After Total Knee Replacement
Your physiotherapist will determine which exercises are appropriate and when to begin them.
1. Ankle Pumps
Gently move your ankle up and down while lying or sitting.
This simple movement helps maintain ankle mobility and encourages circulation when you are less active after surgery.

2. Quadriceps Sets
Lie comfortably with your leg supported and gently tighten the muscles at the front of your thigh.
Hold the contraction briefly, then relax.
This exercise helps reactivate the quadriceps, which can become significantly weakened following surgery.
3. Heel Slides
While lying down, gradually slide your heel toward your body to bend your knee, then slowly straighten the leg again.
Heel slides can help gradually restore knee flexibility.
Do not force the movement or push through significant pain.
4. Straight Leg Raises
Once your physiotherapist confirms that you can perform them safely, straight leg raises may help strengthen the muscles around the hip and knee.
Your physiotherapist should assess your ability to perform this exercise correctly before you begin.
5. Sit-to-Stand Exercises
As strength and mobility improve, your physiotherapist may introduce controlled sit-to-stand exercises.
These help improve:
- Quadriceps strength
- Hip strength
- Functional mobility
- Confidence with daily activities
6. Walking Rehabilitation
Walking is an important part of recovery.
Your physiotherapist may assess:
- Step length
- Weight-bearing
- Use of a walker or cane
- Balance
- Knee movement during walking
Walking aids should be used as recommended, and patients should progress away from them only when it is safe to do so.
Why Is Icing Helpful After Knee Replacement?
Swelling is common after
knee replacement surgery. Excessive swelling can contribute to discomfort and may make it harder to move the knee.
Cold therapy may help temporarily:
- Reduce pain
- Reduce swelling
- Improve comfort
- Make exercises easier to tolerate
Icing should be used appropriately and according to your surgical team’s recommendations.
How to Apply Ice After Knee Replacement
A simple approach is:
- Use a cold pack or bag of ice wrapped in a thin towel.
- Never place ice directly on your skin.
- Place it around the swollen or painful area as directed by your healthcare provider.
- Keep the application relatively brief and follow the duration recommended by your physiotherapist or surgical team.
- Check your skin regularly for excessive redness, numbness, or irritation.
- Allow the skin to return to normal temperature before repeating treatment.
If you have reduced sensation, circulation problems, or another medical condition affecting your ability to safely use cold therapy, ask your healthcare provider before using ice.
Important Precautions After Knee Replacement
Recovery after total knee replacement varies from person to person. Always follow the specific instructions provided by your surgeon and physiotherapist
Avoid progressing exercises too quickly
More exercise isn’t necessarily better. Excessive activity can increase swelling and pain and may interfere with your recovery.
Don’t force knee movement
Your goal is to gradually improve mobility—not aggressively push through severe pain.
Follow weight-bearing instructions
Your surgeon or physiotherapist will tell you how much weight you can safely place through your operated leg.
Use walking aids correctly
A walker, cane, or other aid may be necessary during the early stages of recovery.
Watch for signs of complications
Contact your healthcare team promptly if you develop concerning symptoms such as:
- Increasing redness around the incision
- Significant wound drainage
- Fever
- Rapidly increasing swelling
- Severe or worsening pain
- Calf pain or swelling
- Sudden shortness of breath
- Chest pain
Sudden chest pain or difficulty breathing requires urgent medical attention.
When Should You Start Physiotherapy?
The timing and intensity of rehabilitation depend on your surgeon’s instructions, the type of surgery, your health, and your individual recovery.
Some patients begin rehabilitation very early after surgery, while the program gradually progresses over the following weeks.
Your physiotherapist can determine:
- Which exercises are appropriate
- How many repetitions you should perform
- How much walking is appropriate
- When to increase resistance
- When to progress balance exercises
- When you can safely return to specific activities

FAQ’s
How long does it take to recover from total knee replacement?
Recovery varies between individuals. Your age, overall health, pre-surgical strength, surgical findings, activity level, and adherence to rehabilitation can all influence recovery.
Is swelling normal after knee replacement?
Some swelling is common following surgery and can persist during the recovery period. However, rapidly increasing swelling, severe pain, significant redness, fever, or other concerning symptoms should be reported to your healthcare team.
How often should I do my exercises?
Your physiotherapist will provide an individualized exercise schedule. Performing exercises too aggressively can increase pain and swelling, so follow your prescribed program rather than trying to do as much as possible.
Should I use ice after my exercises?
Ice may help with temporary pain and swelling after exercise, but it is not necessary for everyone. Ask your physiotherapist how and when to use cold therapy based on your recovery.
When can I stop using my walker or cane?
Do not stop using your walking aid simply because you feel you can manage without it. Your physiotherapist can assess your gait, balance, strength, and safety before recommending progression.
Can physiotherapy improve knee bending after replacement?
Yes. Physiotherapy can help restore knee range of motion through appropriately prescribed mobility exercises and progressive rehabilitation. The amount of improvement varies between patients.
Can I exercise at home after knee replacement?
Yes, but only after your exercises have been selected and demonstrated by your physiotherapist or healthcare team. Exercises should be appropriate for your stage of recovery and surgical precautions.
