Comparing cemented hip cups for better stability after surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate the early migration of a cemented BiMobile cup in total hip arthroplasty by comparing two different cup sizes and their associated cement mantles. It is a prospective, single-center, blinded randomized controlled trial involving patients undergoing primary cemented total hip arthroplasty. The study will assess whether increasing the amount of cement used for fixation improves stability and reduces the risk of dislocation, a common complication after hip surgery. Additionally, the BiMobile cup's performance will be compared to the Avantage cup, which uses a standard cup size.

* The patient is expected to need lower limb joint replacement for another joint within one year.
* The patient has a systemic or metabolic disorder leading to progressive bone deterioration.
* The patient has a deformity or disease located in other joints than the hip that needs surgery and that is limiting their ability to walk.
* The patient has an active or suspected latent infection in or around the hip joint.
* The patient's bone stock is compromised by a disease or infection which cannot provide adequate support and/or fixation to the prosthesis.
