The study hypothesis is that the prevalence of obstructive sleep apnea in patients
presenting for total knee or total hip arthroplasty is higher than generally suspected. The
study will include just one arm and results will be compared to a literature control group.
Patients refered for preoperative evaluation will be screened using a standard
questionnaire. Those at high risk of obstructive sleep apnea will then undergo a formal
overnight sleep study (polysomnography).
All patients seen by our orthopedic surgeon for total hip or total knee arthroplasty are
referred for preoperative evaluation. The literature control group comes from a study
performed by Harrison et al. and published in the December 2003 issue of The Journal of
Arthroplasty. The Berlin questionnaire is being used for screening.
This study will also create an ongoing database of clinical outcomes in postoperative
patients with obstructive sleep apnea.
