Endoprosthetic surgery. Such a surgery is necessary if it is impossible to preserve the patient’s natural joint: 3-4 stage of coxarthrosis, 3-5 phase of a femoral head aseptic necrosis, subcapital femoral neck fracture in senior patients, etc.
During a hip arthroplasty surgery, the damaged femoral head and acetabular cavity cartilage get removed and replaced with an endoprosthesis (an artificial joint), comprising of a cup, a liner, a head, and a stem. Prosthetic components may be fixed to the bone tissue mechanically or using bone cement.

A hip replacement surgery lasts, on average, less than 1 hour and is carried out with a spinal anesthesia. Upon desire, the patient may undergo the operation in a medication sleep. As a rule, patients withstand the operation well. At the next day, the patient is allowed to stand up and is ready for the rehabilitation therapy. On average, the patients get discharged in a week after the surgery. After the operation, patients can absolutely return to their full life, except for some contraindicated activities requiring excessive physical efforts. Our patients are recommended to pass their orthopedic examination once a year.
During arthroplasty of a knee, destroyed joint surfaces of femoral and tibia bones get removed and replaced with artificial structures, fixed with bone cement. Consequently, knee prosthesis comprises of two metal joint components (femoral and tibial ones) and plastic liner. In some cases, articular surface of a patella is replaced also.
This surgery is indicated in the following cases: 3-4 stage of deforming osteoarthritis of a knee, aseptic necrosis of femoral and tibia condyles. During the operation, a surgeon applies a special navigation system to straighten the axis of the extremity to eliminate varus (O-shaped) or more complex valgus (X-shaped) knee deformity.

The surgery lasts 1-1.5 hour under the spinal anesthesia. Rehabilitation and walking with crutches begins since the first day after the operation. The patient has to stay at clinic about a week. As a rule, after the operation the patient returns to the regular life, however significant physical loadings are contraindicated.
This operation takes place in the case of instability of a previously implanted prosthesis. This is more complicated surgery, requiring special extenders for revision prosthetic components and titanium inserts (augments). If ligaments of the knee are unstable, a surgeon applies a linked prosthesis system. Revision prosthesis may have been chosen after a temporary antibacterial spacer removal.
