Background: The current study was undertaken to evaluate the clinical efficacy of cemented prosthetics for total hip replacement&nbsp; &nbsp;for management of hip dysplasia in dogs. Total hip arthroplasty will eliminate pain and, restore function of hip joint. 
 
Methods: The dogs with clinical signs of coxofemoral joint affections were diagnosed using standard hip extended ventrodorsal radiographs of pelvis. Those dogs which are not responded to the medical management, with severe degenerative changes and osteoarthritis were selected for surgical management&nbsp; for total hip replacement. The femoral stems used in this study were small (4) and Medium (2). The size of the acetabular cup used ranges from 20 to 22 mm outer diameter. The bone cement used was polymethyl methacrylate (PMMA) low viscosity type bone cement (Simplex-P). Clinical evaluation of the treated dogs on 2nd day post operatively indicated functional outcome (on the basis of WOMAC score) as excellent in four dogs and good in 2 dogs as the mean&nbsp; scores&nbsp; of parameters was 1.0&plusmn;0.36, 0.83&plusmn;0.65, 0.83&plusmn;0.40, 1.0&plusmn;0.68, 0.50&plusmn;0.34, 0.66&plusmn;0.33, 1.50&plusmn;0.50, 1.16&plusmn;0.47, 0.50&plusmn;0.34, 1.50&plusmn;0.42, 2.0&plusmn;0.51 and over all mean of functional outcome is 11.33&plusmn; 4.06 out of 40 points, lower scores reflect better function than higher scores. Radiological and clinical assessment are excellent to good in four cases and poor&nbsp; in two cases, with&nbsp; mean&nbsp; score of 0, 0.83, 1.50&plusmn;0.5,0,0,0, 1.16&plusmn;0.40,0, 1.33&plusmn;0.84. The mean score of radiological and clinical assessment was 4.88&plusmn;1.85 out of 40 points, lesser score indicates effectiveness of the surgical procedure. The lamenessfrom grade V improved onby 45 days to&nbsp; grade I except one dog at grade II, by 60th day,&nbsp; all 5 dogs progressed to grade I and one dog to grade II. The post-operatively radiographic&nbsp; evaluation on day one revealed hip showing cup of the prosthesis into acetabulum.&nbsp; 
 
Result: Total hip replacement using&nbsp; cemented&nbsp; prosthetics for management of&nbsp; Hip dysplasia in dogs was found to be effective in dogs with more than 20 kg body weight&nbsp; and returned to normal limb function after 45th post operative day in 4 out of 6-dogs, whereas in other&nbsp; two dogs, there is a complication of loosening of acetabullar cup after 60 days, the complications will be addressed&nbsp; with uncemented implants.&nbsp;
