The Importance of Physiotherapy Post-TKR

  1. Enhanced Recovery: Physiotherapy accelerates the healing process, helping to reduce pain and swelling while improving mobility.
  2. Strength and Stability: Targeted exercises strengthen the muscles around the knee, providing better support and stability.
  3. Improved Range of Motion: Early mobilisation and specific exercises help regain the knee’s range of motion, crucial for everyday activities.
  4. Preventing Complications: Regular physiotherapy can prevent complications such as blood clots, joint stiffness, and muscle atrophy.
  5. Boosting Confidence: Structured physiotherapy programs can enhance patients’ confidence in using their new knee, promoting a quicker return to normal life.

What not to do after knee replacement surgery

  1. Do not skip your physiotherapy sessions and knee exercises.

Rehabilitation exercises provided to you will play a key part when recovering from a knee replacement. Staying mobile in the weeks and months after surgery will help you to recover faster and improve mobility as well as range of motion in the affected joint.

  1. Do not ignore professional advice.

Follow the advice of your orthopaedic surgeon and your physiotherapist for the best chance of a full recovery as they are professionals in this field of healthcare. 

  1. Do not do too much too soon.

Healing and recovery takes time and everyone progresses at a different rate. Overexerting yourself too soon can prolong your recovery and lead to unnecessary pain and discomfort. Work with your physiotherapist and follow the timeline of your recovery plan.

  1. Do not avoid using walking aids or assistive devices during your recovery.

Assistive devices such as walking frames, crutches and walking sticks are designed to support you during your recovery. These devices are designed to take some of the pressure off your knee, helping you to balance and walk with more confidence. 

  1. Do not use a pillow under your knee in bed.

Placing a pillow under your knee may feel comfortable however this position will cause your knee to bend. This will cause excessive stress on the joint replacement and may cause contractures to happen. Ideally, you need to keep your knee as straight as possible while sleeping.

  1. Do not forget proper wound care and medication.

Proper education on wound care is essential in order to avoid infection and complications that could delay recovery. You need to follow instructions given by your medical provider on how to care for your wound and how to keep it clean and take any medication that has been prescribed to you.
