Joint replacement and corrective surgery on the knee joint

On this page, you will find information on corrective operations on the knee joint, partial or full implantation of artificial knee joint prostheses, in particular information about the models used by us, taking into account the individual situation of patients, the preparation for surgery and postoperative treatment.

Planning and preparation for the operation

In the examination and conversation with a doctor, there is provided information on various methods of performing an operation or joint replacement, especially taking into account the individual situation of patients. For this, the patient must necessarily bring with them the available X-ray images.

In addition, it makes sense to bring with you to the consultation list of currently prescribed medications, as the taking of certain medications should be stopped already a few days before the operation.

Finally, in order to minimize the risks of anesthesia and surgery, it is necessary to undergo the thorough therapeutic examination. The results of the examination should be brought with them on the day of hospitalization in the inpatient department. As a rule, the operation is performed on the day of hospitalization. In the event that not all the examinations were performed, you can go to the Clinic after hospitalization, however, in this case the operation will be postponed.

Corrective surgery (corrective osteotomy) on the knee joint

To prevent the development of long-term effects in young patients with existing symptoms and associated cartilage damage in the presence of X-shaped or O-shaped deformities of the lower extremities, an operation is needed to correct the extremity axis.

To correct the axis of the lower extremities, the bone wedge is removed or placed near the knee joint in the area of the upper articular surface of the tibia or the femur – depending on the type of deformation and the necessary correction. When removing the wedge on the tibia, it is also necessary to perform a dissection of the fibula. After this, the bone is joined and fixed using clamps or metal plate and screws.

Healing of the bone lasts, in general, about three months. Probably, at the initial stage, full load on the leg will be impossible, and you will need two elbow crutches. You can learn how to walk with ulnar crutches under the guidance of our specialists in physiotherapy.
