Abstract

BACKGROUND: As the population ages, total hip arthroplasty has become more common in elderly patients including patients over the age of 90 years. Efficacy in this age group has been established, though literature regarding safety of total hip arthroplasty in nonagenarians is mixed. The anterior-based muscle-sparing (ABMS) approach, which exploits the intermuscular plane between the tensor fasciae latae and the gluteus medius, has proposed benefits of fast recovery, excellent stability, and reduced bleeding and may be adventitious among elderly, more fragile patients. METHODS: A total of 38 consecutive nonagenarians undergoing elective, primary total hip arthroplasty via the ABMS approach for any indication from 2013 to 2020 were identified, and information regarding operative outcomes and patient-reported outcomes was gathered from review of medical records and our institutional joint replacement outcomes database. RESULTS: Included patients ranged from 90 to 97 years of age with the majority classified as American Society of Anesthesiologists score 2 (50%) or American Society of Anesthesiologists 3 (47.4%). The mean operative time was 74.6 minutes ± 13.6 minutes. Of all patients, 5 required a transfusion, 2 patients were readmitted within 90 days, and there were no major complications. The mean hospital length of stay was 2.8 days ± 0.8 days with 22 patients (57.9%) discharged to a skilled nursing facility. Limited patient-reported outcomes data showed statistically significant improvements in most outcomes scores at 6 months to 1 year postoperatively compared to preoperative scores. CONCLUSIONS: The ABMS approach is safe and effective in nonagenarians who may benefit from decreased amounts of bleeding and recovery times associated with the ABMS approach, which is evident from the low complication rates, relatively short hospital lengths of stay, and acceptable transfusion rates compared to previous studies.
