Total hip arthroplasties (THAs) are common surgical procedures that address hip pain and functional impairment, primarily caused by osteoarthritis. Although THA is an effective procedure for addressing osteoarthritis for many patients, some people, particularly those with more severe preoperative pain and impairment, do not experience the improvements in pain, function, and quality of life expected from the procedure (Beswick et al., 2012; Fortin et al., 1999; Tilbury et al., 2016). In 2010, providers performed 326,100 THAs, with 95 percent of them in patients age 45 and older (Wolford, Palso, & Bercovitz, 2015). Although THAs were introduced as a procedure for the elderly, the percentage of patients age 55 to 64 (29 percent) who had a THA in 2010 exceeded the percentage of patients age 75 and older (26 percent) who had a THA (Wolford, Palso, & Bercovitz, 2015). Kurtz et al. (2009) projected that patients younger than 65 would account for 52 percent of THAs by 2030. This growth in hip surgeries for patients younger than 65 is significant because these patients often require more expensive joint arthroplasties that will better withstand the wear caused by physical activity (Bozic et al., 2006).
This measure evaluates whether patients complete a patient-reported functional status assessment (FSA) before and after a THA. Measuring functional status for patients undergoing THA permits longitudinal assessment - from the patient's perspective - of the impact of surgical intervention on pain, physical function, as well as health-related quality of life (Rothrock, 2010).
Clinical Recommendation Statement
The American Association of Hip and Knee Surgeons (AAHKS) states that it is important to ensure that the general/mental health survey be completed prior to surgery during the preoperative visit, as well as the post-operative visit. AAHKS recommends using a general health instrument, such as the Veterans RAND 12-item health survey (VR-12) or PROMIS Global  10 in addition to condition-specific tools (AAHKS, 2015).

A functional status assessment (FSA) is based on administration of a validated  instrument to eligible patients that asks patients to answer questions related to various domains including: pain, physical function, emotional well-being, health-related quality of life, symptom acuity.

The same FSA instrument must be used for the initial and follow-up assessment.
