Hip Osteoarthritis, Patient Satisfaction

Keywords
hip arthroplasty, satisfaction, dual mobility cup
Brief summary
Although the success of total hip arthroplasty, many patients were dissatisfied postoperatively. Patient's reported outcome measures become of a great importance in assessment of the results after joint replacement. The aim of this prospective study is to evaluate and compare postoperative patient's satisfaction after implantation of two commonly used different designs of total hip arthroplasty.
Detailed description
The investigators conducted a prospective comparative study carried out on 180 patients suffering of hip arthritis between 2011 and 2018. They were randomized into two groups of homogenous demographic and clinical data. Group A was treated by cementless T.H.A. with a large head while group B received cementless T.H.A. with a dual mobility cup. Clinical evaluation and preoperative patient's expectation were assessed and compared to the postoperative satisfaction.

Group A included patients received total hip with a large head (32-36mm.) made of cobalt-chrome. The femoral component was a cementless porous coated stem. The cup was a cementless porous coated Trilogy cup and was inserted press fit with primary additional one to three screws. Group B included those received total hip with a dual mobility cup
