Influence of surgical approach on final outcome in total hip arthroplasty for osteoarthritis in patients older than 80 years.

ABSTRACT

PURPOSE: We compared the outcome of total hip arthroplasty (THA) in this age group using direct anterior or posterior approach. METHODS: We performed a retrospective analysis following consecutive primary THA in patients over 80 years. RESULTS: The DAA group demonstrated significantly shorter length of stay, better functional improvement, no dislocation or revision while PA group required two revisions due to dislocation. CONCLUSIONS: The use of DAA for THA in the elderly was associated with shorter hospitalization and superior functional outcomes in the early post-operative period, and had a lower rate of dislocation without increasing risk of early revision.
