title: Primary collared uncemented total hip arthroplasties in the elderly: a safe and reliable treatment option.
abstract: The age of patients undergoing primary Total Hip Arthroplasty (THA) remains fairly constant despite an increasingly elderly population, possibly owing to concern over postoperative complications. This study evaluated 90-day outcomes in patients over 80, undergoing uncemented collared primary THA for osteoarthritis in a high volume unit. Data were recorded from 153 consecutive patients. There were 0.65% mortality rate and 1.3% major systemic complication rate. American Society of Anesthesiologist (ASA) grade was an independent predictor of inpatient complications. Mean preoperative and 90-day postoperative Oxford Hip Score was 24 and 46 respectively. No radiological evidence of femoral stem migration was seen. Our cohort shows low morbidity and mortality rates. ASA not age helps predict inpatient complications. Uncemented collared femoral prosthesis resulted in excellent functional and radiological outcomes.
