The improvement of lower limb biomechanical parameters and subjective evaluation in the area of functioning and pain argues for a positive effect of total hip arthroplasty in the early months after surgery as well as in long\-term results. 3. Increased activity of the examined muscles, especially those stabilizing the hip joint, may be a response to total hip replacement beneficial effect. However, the greater involvement of the tensor fasciae latae muscle, lasting six months after the surgery, proves that there is still a disturbed muscle interaction and the assumption of stabilizing functions by a stronger synergist muscle. 4. A decrease in energy expenditure \(PCI\) during the exercise test, and thus an improvement in gait performance, confirms the effectiveness of the surgery. In addition, the reduction of PCI is conditioned by the increased activity of the gluteus medius in the sixth month after the surgery."]
