Abstract

Problem considered: Earlier versions of cementless femoral stems used in total hip arthroplasty were frequently associated with thigh pain, stress shielding, and challenging revision procedures. A modern design cementless femoral stem was examined in this study with the goal of mitigating these problems.

Methods: This retrospective analysis examined the 10-year follow-up results from an original cohort of 100 patients that had a cementless total hip arthroplasty using a unique femoral design between 2013 and 2014 in a single surgeon study. Comprehensive physical examinations and radiographic analyses were conducted and documented.

Results: Harris Hip Scores (HHS) were recorded at the final follow-up visit, averaging 90.1 ± 8.7. Gruen zone analysis demonstrated good bone maintenance adjacent to the femoral stem with the absence of distal stress shielding, subsidence, and thigh pain. Charnley zones were reviewed as well and revealed minimal osteolytic changes with maintenance of cup position.

Conclusions: The overall findings indicated minimal complication rates unrelated to the femoral stem or cup design, with 10-year cup survivorship of 99 % and stem survivorship of 100 %. This system showed outstanding HHS, low revision rates, optimal bone response, and no instances of thigh pain associated with its design.
