The article deals with the clinical observation of male patient Z., 68 years old, with the diagnosis: right-side idiopathic gonarthrosis of Degree II, flexion contracture, frontal instability, varus deformity of the right knee. The following surgery has been performed: tibial supratrochlear osteotomy, fibular subcapitular osteotomy, osteoperforations and tunnelization of the right femur condyles, hydraulic lavage of the right knee, osteosynthesis of the right leg bones with the Ilizarov fixator. Total endoprosthetics of the right knee has been performed 8 years later. Total period of follow-up is 13 years and one month. The patient is satisfied with the results of treatment.

The results of treatment are presented in a young patient with giant cell tumor of proximal femur using the procedure of total endoprosthetics of the right hip. A double fracture of the right femur middle and lower thirds occurred in him 1.5 years after arthroplasty. The periprosthetic fracture was fixed using cerclage, and the Ilizarov fixator was applied to the lower third fracture. Consolidated femoral fractures, as well as a stable endoprosthesis of the hip was determined by x-ray one year after injury.

The work deals with the constructive features of SLPS ZAO ―Altimed‖ (Belarus) hip endoprosthesis, its advantages and shortcomings, technological aspects of acetabular and hip component implantation and removal in the process of primary and revision interventions. Long-term results of 708 (650 total and 68 hybrid) primary implantations were analyzed as follows: excellent results were obtained in 171 (24,1%) of cases, good ones – in 453 (64%) of cases, satisfactory – in 59 (8,4%) of cases and unsatisfactory results (prosthesis instability) – in 25 (3,5%) of cases. The author propose engineering solutions, which allow to improve the results of endoprosthetic surgeries with the help of this system (SLPS ZAO ―Altimed‖) as well as to reduce intraoperative blood loss, intervention time and invasiveness.
