Tightness of the ankle joint after heel fracture surgery can be partially or fully recovered through functional exercises. The main reason for tightness in the ankle joint after heel fracture surgery is adhesion caused by long-term braking, and it may also be due to discomfort with the plate and sensation caused by the implantation of the plate. If the tightness is caused by the implantation of the plate, it can be completely restored after gradual adaptation and gradual mobilization after surgery. In case of adhesion and stiffness due to prolonged braking, active or passive joint exercises are required under the direction of the surgeon. After exercise, the joint can be partially or completely recovered. If the adhesion seriously affects the function of the joint, it can also be treated by surgery. The most effective way to recover from tightness in the ankle joint after heel fracture surgery is to actively exercise under the guidance of a doctor.
