Significant functional improvements and radiographic stability following fully cemented total hip arthroplasty in elderly patients: A 2-year prospective study.

PURPOSE: Using fully cemented total hip arthroplasty (THA), involving both a cemented cup and stem, remains uncommon in several countries. This study aimed to evaluate the clinical and radiographic outcomes of fully cemented primary THA in an elderly population.

METHODS

This prospective, single-center, longitudinal cohort study enrolled patients in THA. Clinical assessments included the Harris Hip Score (HHS), the Timed Up-and-Go (TUG) test, and the Hip Disability and Osteoarthritis Outcome Score (HOOS). Radiographic evaluation was performed using anteroposterior and lateral X-rays to assess implant positioning and stability.

RESULTS

Forty patients completed the 2-year follow-up (FU), with a mean age of 79.0 ± 6.0 years. Clinical outcomes demonstrated significant improvements at 2-year FU: the mean HHS increased from 42 ± 15 preoperatively to 93 ± 9; TUG improved from 24 ± 25 s preoperatively to 8 ± 3 s; and HOOS improved from 35 ± 14 preoperatively to 84 ± 17. No intraoperative complications or implant-related adverse events were reported during the 2-year follow-up.

CONCLUSION

This study highlights substantial improvements in functional outcomes, patient satisfaction, and radiographic evidence of good implant stability at 2-year follow-up. These findings support fully cemented THA as a safe and effective treatment option for elderly patients.

LEVEL OF EVIDENCE: IV.
