Implication

Prospective cohort study demonstrates durable implant fixation with cementless total hip arthroplasty in young adults, indicating superior long-term stability compared to cemented hip implants.

Key Points

To evaluate the long-term clinical and radiographic outcomes of cementless total hip arthroplasty using an extensively porous-coated stem in patients aged 50 years or younger after a minimum follow-up of ten years.
Prospective study of 100 consecutive patients (115 hips) aged 50 years or younger undergoing primary cementless total hip arthroplasty with an extensively porous-coated stem and cementless acetabular cup.
Outcomes at a minimum ten-year follow-up (mean, 12 years) were assessed via revision rates, radiographic signs of loosening, wear, osteolysis, and functional activity levels, comparing results against a cemented cohort.
At a mean 12-year follow-up (73 patients, 82 hips evaluated), zero acetabular shells or femoral stems were loose radiographically or revised for aseptic loosening.
Three femoral stems required revision due to periprosthetic fracture, and overall reoperation rates were similar to the cemented group due to polyethylene wear revisions in the cementless cohort.
Fixation survivorship of the cementless implants was superior to that of the previously reported cemented cohort, which experienced higher rates of radiographic and aseptic loosening.
