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.
