This article presents a four-stage physiotherapy program for use after certain surgical operations on knee joint cartilage, adapted to the dynamics of tissue healing and reconstruction. In the first stage, the load-bearing time of the operated lower limb in vertical configuration is differentiated, depending on the degree and site of damage and the surgical technique, as well as the patient’s own goals and personal characteristics. Physical agents are also used, along with passive movement of the knee joint without load on CPM devices. Isometric and co-contraction exercises are also used. The patient is taught to walk while relieving the operated limb with crutches. In the second phase of rehabilitation, in addition to routine methods, we use gradual loading on the limb in vertical position, using objective measurements obtained from tensometric platforms. In the third phase standard rehabilitation methods are used. In addition we have implemented monitoring of gradually increased loads, with the goal of restoring limb function, i.e. walking on a level surface and at a variable grade, and basic motor characteristics. The fourth stage is intended for persons whose goal is to return to sport or other professional work requiring a high level of physical activity.
