The postoperative period after Achilles tendon rupture is divided into four phases, and specific rehabilitation exercises are carried out in each phase. Protection and healing period (1st~6th week): Early joint movement and weight bearing under protection are favorable for Achilles tendon healing. Patients are instructed by the doctor to perform several active joint activities, such as dorsiflexion, plantarflexion, inversion and eversion of the ankle, but at the same time passive joint activities and stretching should be avoided. Massage the scar appropriately to promote healing and prevent adhesion and stiffness. Patients should elevate the affected limb as much as possible throughout the day and avoid prolonged weight-bearing positions. Early joint activities (weeks 6~12): After complete weight-bearing of the joints under the protection of braces and crutches, patients should gradually get rid of the crutches and wear shoes for complete weight-bearing, and put a heel cushion in the shoes, and gradually reduce its height with the improvement of joint activities until the gait is normal and then remove the cushion. When cycling exercises are carried out, the forefoot is weight-bearing, and the amount is gradually increased. After the exercise, elevate the affected limb and apply ice to avoid swelling. Early muscle strength exercises (weeks 12~20): carry out progressive heel lift tolerance exercises, first complete the heel lift from plane to slope with both feet, and then change to one foot to complete the exercise. After completing the heel raises, step down exercises are performed, with the height of the steps gradually increasing, and the difficulty of the balance training is also gradually increasing. Late muscle strength exercises (20th to 28th week): you can start cycling and running exercises, continue lower limb muscle strength and flexibility exercises, step training, and specific motor skills training. During the rehabilitation process, patients should exercise gradually under the guidance of physicians or rehabilitation therapists, and should not exercise strenuously blindly to avoid secondary injuries.
