Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

On a large population of patients having undergone total hip arthroplasty, divided into two cohorts constituted according to the type of femoral stem implanted (with or without proximal coating by MectaGrip):

Primary objective: To compare between the two groups the radiological osseointegration of the stems five years after arthroplasty.

Secondary objectives: To compare between the groups

* The functional outcome of the arthroplasty
* The frequency of radiological abnormalities (stress shielding, osteolysis, periprosthetic fractures or cracks, periprosthetic ossifications)
* Frequency of complications
