Chen W, Klemt C, Padmanabha A, et al. - This research was sought to compare the survivorship of isolated bearing exchange and single/both component revision for patients with periprosthetic osteolysis without component loosening, and to distinguish potential risk factors correlated with failures of isolated bearing exchange. Researchers examined a sum of 228 consecutive cases of revision total hip arthroplasty for progressive osteolysis without component loosening in 2 groups: 124 component revision and 104 isolated bearing exchange. The primary endpoint included survival, with failure characterized as repeat revision or reoperation for any reason. They also examined patient risk factors. This research indicated that isolated bearing exchange is correlated with a similar outcome in comparison with component revision for aseptic osteolysis without loosening, illustrating that isolated bearing exchange is a viable option for selected patients with osteolysis in the setting of well-fixed THA components. This offers clinically beneficial information for surgeons in the surgical treatment of THA patients with wear and osteolysis without component loosening.
