dc.description.abstractPurpose: Total hip arthroplasty (THA) is one of the most common and successful orthopedic procedures, markedly enhancing patient quality of life, reducing pain severity, and maximizing post-operative function. This study assesses the United Conformity Stem Femoral Hip System, distinguished by its standard and high offset options and the ability for precise adjustment to optimize joint stability and tension based on the surrounding soft tissue, with the goal of improving patient outcomes for THA. Methods: A cohort of 415 patients, who underwent primary THA with the United Conformity Stem Femoral Hip System from November 2019 to November 2021, was retrospectively reviewed to evaluate the clinical effectiveness, safety, and survival over the first 2 years post-operation. The primary endpoints of our study were significant improvements in four patient-reported outcome measures (PROMs), including Hip Disability and Osteoarthritis Outcome Score-Joint Replacement (HOOS-JR), Lower Extremity Activity Scale (LEAS), Visual Analog Scale (VAS), and Harris Hip Score (HHS) at 24 months post-procedure when compared to preoperative scores. Secondary outcomes included implant survival and radiographic assessment for stability. Results: Within the cohort, a total of 209 females and 66 males achieved a minimum of 2-year follow-up (66%). The mean age was 61.5 ± 9.9 years, with a mean BMI of 26.0 ± 5.4 kg/m2. At the 2-year follow-up, statistically significant improvements in HOOS-JR, LEAS, VAS, and HHS were observed compared to their baseline preoperative scores. Radiographic evaluations of the implants by two independent observers corroborated these PROMs findings. The cohort reported three revisions, one of which involved stem revision. Conclusions: Our study affirms that the United Conformity Stem Femoral Hip System yields notable enhancements in functional capability and short-term radiographic stability in our evaluation of 2-year outcomes in primary THA, irrespective of surgical approach (anterior or posterior). These findings support the United Conformity Stem System’s capacity to meet the rising expectations of patients and surgeons alike, while providing excellent short-term outcomes.en_US
