Knee replacement surgery can significantly improve mobility and quality of life, but surgery is only one part of the recovery.
Proper rehabilitation after surgery is important to help patients regain strength, improve movement, balance and confidence in their daily activities.
Mrs Ng’s case is a real example of why rehabilitation should not be overlooked after a knee replacement.
Mrs Ng’s Story: 10 Years After Left Knee Replacement
Mrs Ng underwent a left knee replacement approximately 10years ago.
However, after her surgery, she did not receive or follow a structured physiotherapy rehabilitation programme. She therefore missed the opportunity to properly work on strengthening, mobility, balance and functional movement during her recovery.
Over the years, she has experienced occasional pain in her left knee together with muscle weakness. She also experiences pain in her right leg.
This raised an important question:
Could weakness in one leg affect the other side over time?
What Can Happen After Knee Replacement Without Proper Rehabilitation?
Recovery after TKR is not simply about the surgical wound healing.
After surgery, the muscles around the knee and lower limb can become weak due to pain, reduced activity and a period of limited movement.
Without appropriate rehabilitation, some patients may continue to have difficulties such as:
- Reduced lower-limb muscle strength
- Difficulty getting up from a chair
- Reduced balance and stability
- Difficulty with stairs
- Reduced walking endurance
- Reduced confidence during movement
- Compensatory movement patterns
Sometimes, these problems may not always be obvious immediately.
A person may be able to return to walking and daily activities, but underlying weakness or movement limitations can remain.
Why Can the Other Leg Also Become Painful?
When one leg is weaker or painful, a person may unconsciously change the way they stand, walk or transfer their weight.
For example, they may place more weight on the stronger leg or change their movement patterns to avoid discomfort.
Over time, this may place different demands on the other leg.
However, pain in the opposite leg can have many possible causes and cannot automatically be attributed to the previous knee replacement or lack of rehabilitation. A proper assessment is important to understand the individual’s condition.
Why is Physiotherapy Important After Knee Replacement?
A structured physiotherapy programme provides guidance on how to safely progress after surgery.
1. Regaining Knee Movement
Physiotherapy can help patients work towards improving knee range of motion through appropriate exercises and movement practice.
2. Rebuilding Muscle Strength
Strengthening the quadriceps, hamstrings, gluteal muscles and other lower-limb muscles is important for walking, standing and everyday activities.
3. Improving Balance
After surgery, patients may feel less stable when standing or walking.
Balance exercises can help patients gradually regain their stability, control and confidence.
4. Improving Walking
A physiotherapist can assess walking patterns and identify compensatory movements or difficulties using a walking aid.
Walking can then be progressed according to the patient’s ability.
5. Returning to Daily Activities
Rehabilitation should not only focus on exercises.
Patients also need to regain the ability to perform everyday movements such as:
- Getting in and out of a chair
- Walking around the home
- Climbing stairs
- Standing for longer periods
- Performing household activities
Is It Too Late to Start Rehabilitation?
Mrs Ng’s case also highlights an important point:
Rehabilitation is not only for the first few weeks after surgery.
Even years after a knee replacement, patients may benefit from an assessment if they notice weakness, difficulty walking, reduced balance or changes in their usual movement.
A physiotherapist can assess the person’s current strength, mobility, balance, walking pattern and functional abilities before developing an appropriate exercise programme.
For someone like Mrs Ng, the goal is not simply to look at the replaced knee. We also need to consider the whole lower limb and how both legs are functioning together.
How Home Physiotherapy Help After Knee Replacement
For some post-operative patients, travelling to a physiotherapy centre can be difficult, particularly during the early stages of recovery.
A home physiotherapy programme allows rehabilitation to take place in the patient’s familiar environment.
Depending on the individual’s condition, treatment may include:
- Strengthening exercises
- Knee mobility exercises
- Balance training
- Walking and gait training
- Functional exercises
- Stair practice
- Education on safe movement and exercise progression
The programme can also be adjusted as the patient progresses.
Key Takeaway
Mrs Ng’s experience highlights that knee replacement surgery is not the end of recovery — rehabilitation is part of the journey.
Proper rehabilitation can help patients work towards better strength, movement, balance and function after surgery.
Even years after knee replacement, changes such as persistent weakness, pain, reduced balance or difficulty walking should not simply be ignored.
A physiotherapy assessment can help identify areas that may need attention and determine an appropriate rehabilitation programme.
