The objective was measure quadricep strength after Total Hip Arthroplasty (THA) and kinetic treatment and then determine its impact on the functional recovery of patients with hip osteoarthritis. A total of 79 (25 were male and 54 were female) patients with THA. Exclusion criteria were previous extra-system kinetic treatment, operated on for hip fracture, not completing the treatment. Maximum Isometric Strength (MIS), Time Up and Go (TUG), Modified Harris Hip Score. There was a significant increase in the MIS of the post-treatment operated knee extension in both men and women (p < 0.0001 SE = 0.43; p < 0.0001 SE = 1.22, respectively). In the TUG, the execution time was significantly lower post-treatment in both men and women (p < 0.0001 SE = 0.77; p < 0.0001 SE = 0.94, respectively). The final Harris score increased significantly post-treatment in male and female (p < 0.0001 SE = 2.90; p < 0.0001 SE = 1.96, respectively). the association between MIS and the Harris score, it was noted that, for a 1 kg increase in this measure compared to the initial assessment, the Harris score, after 12 weeks of treatment, increased by 0.179 points (β = 0.179; p = 0.050). The conclusions were Indicate an increase in knee extension MIS of the operated hip after treatment in both sexes. At the same time, functionality increased post-treatment in both male and female.
