The aim of the study was to examine how much physical therapy affects the extent of hip mobility after rehabilitation after the total hip endoprosthesis has been installed. Using the quantitative descriptive analysis, the t-tests for dependent and independent samples and the correlation of individual were processed with 13 different individual results (N=60, F=61,7%, M=38,3%, age from 41 to 90 years, X=68,22 years of age) who underwent the total hip endoprosthesis surgery before and after the commencement of the rahabilitation program at the Special Hospital for Medical Rehabilitation Thalassotherapia Crikvenica in a period of one year. After rehabilitation there is a significant difference in pain estimation, which indicates that the pain is significantly reduced or is adsent (p<0,01%). Total use of walking aids decreased by 13,3%. After rehabilitation, the hip range of motion equally greatly increased in all measurement ranges in both genders, while male and female gender showed a greater difference only in the anteflexion with the elongated knee range of motion in women. It was found that the age and time from after operation to commencement of rehabilitation have no effect on the success of rehabilitation and that the comorbidity is an important factor of the recovery process after total hip endoprosthesis surgery. The well-designed and implemented rehabilitation program has, besides other factors, a major impact on recovery after the installation of total hip endoprosthesis, irrespective of age, gender and time commencment of rehabilitation.
