Physiotherapy is one of the most important components of recovery after knee replacement surgery. While the surgery replaces the damaged joint, rehabilitation helps patients regain strength, flexibility, balance, and mobility. Many patients preparing for surgery ask an important question: "How soon should physiotherapy start after knee replacement?"
At JJ Aesthetics, we believe patients achieve the best outcomes when they understand the recovery process before surgery. Early physiotherapy plays a major role in helping patients return to daily activities safely and confidently.
When Does Physiotherapy Usually Begin?
Physiotherapy Often Starts Within 24 Hours
In most cases, physiotherapy begins on the same day as surgery or within the first 24 hours afterward.
Modern knee replacement recovery programs encourage early movement because it helps:
- Improve blood circulation
- Reduce stiffness
- Prevent complications
- Restore mobility
- Accelerate recovery
Many patients are surprised to learn that they may stand and take their first few steps shortly after surgery under professional supervision.
Why Is Early Physiotherapy Important?
Years ago, patients often remained in bed for extended periods after surgery. Today, orthopedic specialists recognize that early mobilization offers significant benefits.
Reduces Joint Stiffness
The knee can become stiff quickly after surgery if movement is delayed.
Early exercises help maintain:
- Range of motion
- Flexibility
- Joint function
Improves Blood Flow
Movement promotes healthy circulation and may reduce the risk of complications such as blood clots.
Builds Confidence
Many patients feel anxious about moving their new knee.
Working with a physiotherapist helps patients gain confidence and learn safe movement techniques.
Speeds Recovery
Patients who begin rehabilitation early often regain independence faster.
What Happens During the First Physiotherapy Session?
The initial session is usually gentle and focused on basic mobility.
Your physiotherapist may help you:
Move the Knee Safely
Simple exercises are introduced to encourage knee movement.
Sit Up and Stand
Patients are often assisted in moving from bed to a seated position and then standing safely.
Begin Walking
Most patients take a few steps with:
- A walker
- Crutches
- Other mobility aids
Learn Safety Techniques
You will receive instructions on:
- Getting in and out of bed
- Sitting safely
- Using stairs if appropriate

Straight Leg Raises
These exercises build muscle control and stability.
Knee Bending Exercises
Improving knee flexion is an important recovery goal.

Gradually increasing walking distance helps restore mobility and endurance.
Can Delaying Physiotherapy Affect Recovery?
Yes.
Delaying rehabilitation may increase the risk of:
- Joint stiffness
- Reduced flexibility
- Muscle weakness

- Difficulty achieving optimal results
Patients who actively participate in physiotherapy often achieve better long-term outcomes.
How Long Will Physiotherapy Be Needed?
The duration varies depending on:
- Age
- Health status
- Fitness level
- Recovery progress
- Surgical complexity
Many patients continue structured physiotherapy for:
6 to 12 weeks
Some individuals benefit from additional rehabilitation beyond this period.
Is Physiotherapy Painful?
Some discomfort is normal during rehabilitation because the knee is healing and adapting.
However, physiotherapy should not cause severe pain.
Patients may experience:
- Mild soreness
- Stretching sensations
- Temporary stiffness
Your physiotherapist will adjust exercises according to your recovery stage and comfort level.
Can Physiotherapy Be Done at Home?
Yes.
Many patients begin with:
Home-Based Physiotherapy
A physiotherapist visits the patient's home during the early recovery period.
Benefits include:
- Convenience
- Reduced travel
- Personalized attention
Outpatient Physiotherapy
As mobility improves, patients often transition to clinic-based rehabilitation.
Home Exercise Programs
Patients are usually given exercises to perform independently between therapy sessions.
Signs That Physiotherapy Is Working
Positive signs include:
- Improved walking ability
- Increased knee flexibility
- Reduced stiffness
- Better balance
- Enhanced strength
- Greater independence
Progress may be gradual, but consistency is key.
