Vergelijkende studie naar slijtage van polyethyleen van heupprothesen bij jonge patiënten.

Wear of the polyethyelene cup is a main reason for long-term failure of total hip arthroplasties. Especially in young patients, polyethylenes with high wear resistance are mandatory. In this study, we compare the wear of cups made of X3 crosslinked polyethylene versus traditional polyethyelene. At the surgical theatre, patients are randomized in two groups; traditional versus X3-cups. Except for the type of polyethyelene, all other parts of the surgery and rehabilitation are equal. Clinical and radiological follow-up will be used to determine aseptic loosening, osteolysis and wear patterns.

Wear of the polyethyelene cup is a main reason for long-term failure of total hip arthroplasties. Especially in young patients, polyethylenes with high wear resistance are mandatory. In this study, we compare the wear of cups made of X3 crosslinked polyethylene versus traditional polyethyelene. We hypothesize that the X3 crosslinked polyethylene cups have lower wear rates and therefore longer follow-up times.

Follow-up will be done according to our standard protocol with a visit to the outward clinic at 6 weeks, 6 months, 1 years, 2 year, 3 year, 5 years, 7 years and 10 years. Both clinical data and radiological data will be recorded.
