Migration in Total Hip Arthroplasty with a Cemented BiMobile Cup: Better Stability with More Cement? (Be-Mobile)
Objective: The main objective of this study is to compare the (early) migration of the cemented BiMobile cup at two year post-surgery between two different cup sizes after standard optimal reaming, and consequently adjusting the cement mantle into circa 2 or 4 mm, in patients with a primary cemented total hip arthroplasty (THA). Additionally, the results of the BiMobile cup will be compared to the Avantage cup, which is placed with a standard cup size, resulting in a cement mantle of approximately 2 mm. Study design: A prospective single centre blinded randomised controlled trial. Study population: All patients who meet the criteria to undergo a cemented THA.
• Patient requiring an elective primary cemented THA.
• Male patient ≥70 years old and female patient ≥65 years old.
• Ability and willingness to follow instructions and to return for follow-up evaluations.
• The patient is able to understand the meaning of the study and is willing to sign informed consent.
• Understanding the Dutch language.
