Abstract

Dual mobility cups (DMC) in total hip arthroplasty (THA) are becoming popular among orthopaedic surgeons. Substantial benefit of their use has been reported among high risk patients, particularly in reducing post-operative hip instability (dislocation). Many reports stated some concern when implanted in young and active people where complications such as polyethylene wear and mechanical loosening could potentially be higher. This Middle Eastern study analyses a retrospective series of THA for any aetiology other than infection, using DMC for the acetabular component in 75 patients (85 implants) less than 70 years old. No instability, intra-prosthetic dislocation or mechanical failure was reported during a mean follow-up of five years. The only major complication was a post-operative infection. The mean post- operative modified Harris hip score was 97.1 out of 100. All patients resumed their daily activities and all religious practicing patients were able to accomplish their prayer positions without pain. DMC is found to be an interesting option in reducing dislocation events in young patients. Those excellent short-term results would encourage surgeons to use DMC in an active and highly demanding population. Further research is necessary to confirm maintenance of such results at long term follow-up.
