In patients with advanced degenerative changes of the hip joint, the joint endoprosthesoplasty is the only effective method of treatment. Technically correctly performed surgery and choosing the appropriate implant are prerequisites for optimal result of the treatment. The aim of the study was to evaluate whether and to which extent the endoprosthesoplasty of the hip joint affects parameters of the balance control process following the total hip alloplasty surgery. Group of 20 patients age 52 – 64 after implantation of ANTEGA cementless endoprosthesis with anatomical stem was included in the study. In all cases, the operation was performed utilising posterior access . Immediately after surgical operation , during early postoperative period all patients underwent rehabilitation according to the standards developed at “Opolskie Centrum Rehabilitacji” [Rehabilitation Center of Opole] in Korfantów. Tests were conducted on the day preceeding operation and in three months after operation. Unconstrained standing on a force-plate for 20 seconds was performed during the test. Data was recorded with frequency of 20 Hz. Obtained results suggest that maintenance of stable body posture is easier for patients after total endoprosthesoplasty of the hip joint.
