If a patient has an Achilles tendon rupture, it usually takes about 8-10 weeks to get off the ground after surgical treatment. After surgery for Achilles tendon rupture, the ankle should be immobilized in plantarflexion for 5-6 weeks to promote the recovery of Achilles tendon rupture, and then immobilized in neutral ankle position for 3-4 weeks. After the above treatment, usually the Achilles tendon rupture can be fully recovered, and then the immobilization can be withdrawn, and gradually perform the functional exercise of ankle flexion and extension, and go down to the ground for light weight-bearing activities. If the immobilization is removed too soon after the surgical treatment of Achilles tendon rupture, and flexion and extension of the ankle and weight-bearing activities are carried out, the repair of the Achilles tendon rupture may be affected, and it may be easy to cause the Achilles tendon to rupture again in the later stage of the activity.
