Objective: To analyze the functional outcome of conversion total hip arthroplasty (THA) using Harris hip score and evaluate intraoperative difficulties faced during conversion to THA.
Methodology: This prospective study evaluated five-year outcome of THA in patients with failed Austin Moore hemiarthroplasty (AMH). From June 2014 to November 2020 (by a nonrandom consecutive sampling technique), all patients who had AMH were evaluated and those with failed procedures were sorted out. We selected patients for THA who were followed up for five years. Harris Hip Scores (HHS) was calculated for the functional outcomes.
Results: Out of 28 patients, 16(57.14%) were females and 12(42.86%) males. Mean age was 61.1+3.3 years. Excluding two patients who died (due to systemic causes), HHS evaluation at one year 15 (53.6%) showed excellent, 9 (32.1%) good, one (3.6%) fair and one (53.6%) poor result. After 5-years, 6 (21.4%) showed excellent 18 (64.3%) good, one (3.6%) fair, and one (3.6%) poor result. The mean HHS was 84.7±6.7 at the last follow-up.
Conclusion: THA after failed AMH is an excellent treatment strategy to control pain and restore function.
