Outcomes of total hip arthroplasty in the octogenarian population
2012
Although total hip arthroplasty (THA) has been shown to be a cost-effective means of treating hip arthritis, there is some ambiguity within the literature as to its success in those over 80 years of age. With the rapid expansion of this population group and an estimated 40% rise in THA figures expected by 2026, this study aims to review the results of primary THA in the octogenarian population. A series of 510 consecutive cases was obtained from the local arthroplasty database, consisting of all patients aged 80 years and over who underwent primary THA between 1994 and 2004. A control group of 3404 individuals under 80 years was also established using the same database and inclusion criteria. Mean follow-up for the octogenarian group was 5.9 years. Pain scores were comparable five years post-operatively in both groups (P=0.479); in particular 81.5% of octogenarians and 80.2% of the control noted no pain. Pre-operatively, the mean Harris Hip Function and Harris Hip Score were significantly lower in the octogenarian group by 4.3 and 4.2 points (P
