The aim of this study was to compare short-stem with standard-stem prosthesis outcomes in total hip arthroplasty. This study was performed as a randomized clinical trial. 84 patients were selected among cases referred to Sina University Hospital, Tehran, Iran between April 2010 and April2012 with severe hip osteodegeneration. Total hip arthroplasty were performed with short-stem or standard-stem prostheses after obtaining written informed consent from patients. Balanced Block Randomization method was used to do a random allocation. Clinical outcomes were evaluated based on Harris Hip Score (HHS). Patients were followed up for at least one year. All patients were examined at 2 weeks, 6 weeks, 3 months, 6 months and one year after surgery. In each visit, Control X-Ray was obtained and bone and prosthetic position were assessed. Also, the symptoms such as infection, pain, claudication, ability to climb stairs, using crutches and weight bearing were rechecked.
