Abstract
OBJECTIVE: To determine the impact of each cause of revision surgery in total hip arthroplasty during the period 2009-2013. To analyse the relationship between these causes with different variables. MATERIALS AND METHODS: A study was conducted on 127 patients who had hip replacement revision surgery in our hospital during this period. Parameters, such as age, sex, date of primary arthroplasty, prosthetic replacement date, and main cause of the revision were recorded. Those revisions performed within 5 years after the primary arthroplasty were considered as early rescue. RESULTS: The most common cause of rescue was aseptic loosening in 38 (30%) followed by instability in 30 (24%). In terms of age at the time of rescue, statistically significant differences were found, with it being significantly higher in patients re-operated for a fracture. Differences in age at first surgery were found to be 7 years younger than those with late rescue (63.40) with respect to early (70.21). DISCUSSION: Similar results to ours have been observed in other published series, except for the higher incidence of instability in early rescue. CONCLUSIONS: This study demonstrates aseptic loosening and instability as the most frequent causes of revision surgery in our hospital. Age is a very influential factor in relation to longevity of primary arthroplasty. Complications were higher in when the primary hip replacement is implanted in older patients.
