Overview
About Post-Knee Replacement Recovery
Post-knee replacement rehabilitation is one of the most important determinants of surgical outcome. It begins the day after surgery and progresses through distinct phases: early mobilisation to prevent stiffness and clots, progressive strengthening, functional training for daily activities, and finally return to recreational activities. Patients who follow a structured rehabilitation programme consistently achieve better range of motion, less pain, and higher satisfaction than those who do not.
Key Benefits
Early mobilisation from day one prevents stiffness and deep vein thrombosis
Structured progression ensures the new knee achieves its maximum range of motion
Quadriceps and hip strengthening exercises reduce load on the new implant
Gait training corrects abnormal walking patterns developed before surgery
Builds patient confidence in the new knee — essential for long-term success
Frequently Asked Questions
When does rehabilitation start after knee replacement?
Rehabilitation begins the day after surgery. A physiotherapist will help you stand and take your first steps with a walker. Exercises for the knee and ankle are started on the same day to prevent blood clots and stiffness.
What exercises are done after knee replacement?
Early exercises include ankle pumps, quad sets, straight leg raises, and knee bends (flexion exercises). As recovery progresses, exercises advance to standing strengthening, step-ups, cycling, and walking on different surfaces. A home exercise programme is provided at discharge.
How much knee bending should I achieve?
The target is 90° of flexion by 4–6 weeks and 110–120° by 3 months. Good flexion is critical for activities like climbing stairs, getting up from a chair, and squatting. Early physiotherapy is key to achieving adequate range of motion.
When can I drive after knee replacement?
For right knee replacement, driving is typically resumed at 4–6 weeks when you can comfortably apply the brake. For left knee replacement (in automatic cars), return to driving may be possible at 3–4 weeks. Your surgeon will confirm clearance.
What activities should I avoid after knee replacement?
High-impact activities like running, jumping, and contact sports are best avoided with a knee replacement. Low-impact activities like walking, swimming, cycling, and golf are highly recommended and well-tolerated by most knee implants.
