The American Academy of Orthopaedic Surgeons issued an evidence-based clinical practice guideline for managing osteoarthritis (OA) of the hip, with a focus on the risks of total hip arthroplasty (THA).¹

True or false? After THA, obese patients with symptomatic OA of the hip report lower levels of satisfaction and less improvement in pain and function than non-obese patients.

FALSE: Obese patients with symptomatic hip OA may achieve lower absolute outcome scores than non-obese patients, but they report similar satisfaction and relative improvement in pain and function after THA. Most studies defined obesity as a BMI of > 30-a relatively low cutoff that may mask more dramatic differences in outcomes.

True or false? Increased age is linked with lower functional and quality-of-life outcomes in patients with symptomatic hip OA who undergo THA.

TRUE: Compared with younger patients, older patients with symptomatic hip OA who undergo THA have lower functional and quality-of-life outcomes-and may have higher mortality risk as well. Younger age may be associated with a higher risk of revision surgery.

True or false? Mental health disorders (eg, depression and anxiety) are associated with decreased function, pain relief, and quality-of-life outcomes in patients with symptomatic hip OA who undergo THA.

TRUE: Mental health disorders such as depression and anxiety are associated with decreased function, pain relief, and quality-of-life outcomes in patients with symptomatic hip OA who undergo THA. In addition, patients with mental health disorders have higher rates of revision (>10% after 10 years in patients with depression in one study).

True or false? The use of tobacco products has no effect on the risk of complications after THA.

FALSE: Patients who use tobacco products are at increased risk for complications after THA.

True or false? Preoperative physical therapy may improve early function after THA in patients with symptomatic hip OA.

TRUE: Limited evidence supports preoperative physical therapy as an intervention to improve early function in patients with symptomatic hip OA after THA.
