Walking is possible already on the second day after the operation, provided that the operated limb is relieved with elbow crutches. A special orthosis is also placed on the knee to protect the tibia from posterior displacement relative to the femur, which is to prevent the PCL ligament graft from stretching. Free walking with full load on the limb and without an orthosis is possible when the physiotherapist determines that the knee is fully prepared and trained for it, and moreover, walking does not cause recurrence of swelling or pain in the joint. The time of weaning off the crutches and orthosis is usually 6-8 weeks after the surgery.
