Brief Summary
A randomised controlled study comparing two types of ultra-porous coated uncemented cups in total hip arthroplasty. Primary objective is to investigate if the clinical, radiological and patient-reported outcome of the new MobileLINK TabecuLINK cup combined with an X-LINKed insert is non-inferior to the clinical and radiological outcome of the Pinnacle Gription series 100 cup combined with the Marathon liner. Patients are evaluated up to 15 years postoperatively.

Study Arms (2)
MobilLINK TrabecuLINK cup
ACTIVE COMPARATORThe investigational device in this study is the newly developed MobilLINK TrabecuLINK cup. It will in this study be combined with a uncemented LCU stem. The MobilLINK TrabecuLINK cups are made from Tilastan, a Ti6A4V alloy. The MobileLINK press-fit shells are hemispheric and polar flattened. An equatorial press-fit is built into the shells for primary stability after cementless implantation. All shells have a polar hole, which is used to connect an impactor handle for implantation of the shell. This polar hole can be closed with a polar screw. The MobileLINK TrabecuLINK shells have a 3D printed trabecular surface structure with a pore size of 610 to 820 μm and a porosity of 70 %.
Pinnacle Gription Series 100 cup
ACTIVE COMPARATORFor the control group a Pinnacle Gription cup series 100 with a apex hole eliminator will be used together with a neutral cross-linked polyethylene (XLPE) Marathon liner (DePuy Synthes by Johnson \& Johnson, Norderstedt, Germany). The Pinnacle Gription cup is a hemispherical, single-geometry, titanium press-fit cup with a solid body. The outer surface consists of a porous coating with 300 μm sintered titanium beads coated with an extra layer of irregularly shaped pure titanium pieces. In cases where no initial stability can be reached when using the Pinnacle 100 series, the Pinnacle Gription sector cup with additional bone screws will be used. The cross-linked Marathon insert is made of 1050 GUR resin, irradiated with 50 kGy, remelted and plasma sterilized. The Pinnacle Gription cup will be implanted together with a Corail stem (DePuy Synthes).
