One-staged ipsilateral and contralateral total hip and total knee arthroplasties were compared. A total of 103 patients underwent a 1-staged total knee arthroplasty and total hip arthroplasty between January 1975 and July 1997 (67 contralateral and 36 ipsilateral patients). No prostheses were found to be loose or revised. ⋯ There was no significant difference in survival between the contralateral and ipsilateral groups. There was only 1 death within 3 months of the operation. The severity of these patients' deformity may necessitate these procedures be done at 1 operation with consideration of mortality and morbidity risks.

Sleep apnea syndrome (SAS) is a condition of repeated episodes of apnea and hypopnea during sleep. It can cause life-threatening morbidities, including cardiac arrhythmia and ischemia, hypertension, and respiratory arrest, and even death. ⋯ There were 19 patients with a preoperative diagnosis of moderate or severe SAS; 15 patients received continuous positive airway pressure or bilevel positive airway pressure noninvasive ventilation, 1 patient experienced respiratory arrest secondary to intraoperative propafol, and 2 patients developed postoperative respiratory depression. Avoidance of opioids and sedative drugs, awareness of the possibility of acute airway obstruction, and close monitoring during and after surgery are vital in patients with SAS.
