Dual Mobility Cup: Does it Improve Patient's Satisfaction After Total Hip Arthroplastry?

Not Applicable

Completed

• Conditions: Patient Satisfaction; Hip Osteoarthritis
• Interventions: Procedure: large head; Procedure: dual mobility cup

• Registration Number: NCT04333316
• Lead Sponsor: Tanta University

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.
