Performance-Based Versus Self-Reported Outcomes Using the Hip Disability and Osteoarthritis Outcome Score After Total Hip Arthroplasty

Abstract

Objective-The purpose of this study was to explore the relationship between patients' selfreported and performance-based function after total hip arthroplasty (THA).Design-Twenty-three patients (age 61.4 ± 8.3 years) undergoing primary THA for hip osteoarthritis participated. Self-reported function and recovery was measured using The Hip Dysfunction and Osteoarthritis Outcome Score (HOOS) ADL and Pain subscales. Performancebased functional measures included Timed Up and Go Test (TUG), Stair Climbing Test (SCT), and the 6 Minute Walk Test (6MW). Outcome measures were assessed pre-and post-operatively at one and six months.Results-One month after THA, performance-based function declined compared to baseline as follows: TUG: −22.1 ± 25.4%; SCT: −58.5 ± 63.6%; and 6MWT: −22.6 ± 31.7%. In contrast, self-reported function on the HOOS ADL significantly improved one month after THA compared to baseline: 40.8 ± 33.3%. One to six months after THA, there were significant improvements in TUG, SCT and 6MWT which paralleled improvements on the HOOS subscales, although changes were not significantly correlated. Conclusion-The disparity between changes in HOOS scores and functional performance postoperatively suggests that patients may overestimate their functional capacity early after THA, likely in response to pain improvements over the same time period. Therefore, outcomes assessment after THA should include both self-report and performance-based functional measures.

Different interventions, same outcomes? Here are four good reasons

“…One month after total hip arthroplasty, Dayton and colleagues4 report that performance-based function (eg, timed up and go, 6 min walk test and stair climbing test) declined compared with baseline, whereas self-reported function improved compared with baseline. Similar disparate findings were evident in patients after a total knee arthroplasty when comparing self-reported knee injury and osteoarthritis outcome scores to performance measures—most self-report measures assessing knee function improved from baseline, whereas the physical performance measures declined from baseline 5…”

Empowering education of arthroplasty patients' significant others in three Southern European countries

“…As quality of life is improved with arthroplasty, age is not a barrier for it (Jones, Voaklander, Johnston, & Suarez‐Almazor, ). Older persons increasingly choose to undergo arthroplasties (Rubin, Blood, & Defillo‐Draiby, ), but they may face difficulties following discharge (McMurray, Grant, Griffiths, Lefford, & Wilson, ), for example, decreased mobility (Dayton, Judd, Hogan, & Stevens‐Lapsley, ). Family caregivers, in this study reported as significant others, are important sources of support during recovery (Heine, Koch, & Goldie, ).…”

“…Apart from the increased incidence of arthroplasties due to the increased longevity of the population (Singh, ), the necessity of assessing the expected and received knowledge of significant others of patients undergoing arthroplasty is evident also by the fact that they are compelled to care for the person who faces decreased mobility (Dayton et al., ), needs increased support after the operation and is generally over 60 years old (Glyn‐Jones et al., ). This is further complicated by the fact that people who take care of persons older than 65 years, as persons having arthroplasties, are 63 years old on average (Administration on Aging, ) and they are expected to undertake a caring role for which they are not trained.…”

Magnitude of Deformity Correction May Influence Recovery of Quadriceps Strength After Total Knee Arthroplasty

“…[9, 10] Previous studies, including those examining the use of computer assisted techniques, have been primarily limited to self-reported outcomes, and fail to capture meaningful declines in quadriceps strength likely to impact function during the early postoperative period. [11, 12] Furthermore, those that have examined relationships between surgical deformity and strength outcomes have been limited to one measurement of alignment: mechanical axis (MA). [13, 14] Additional measures of alignment, including the distal femoral angle (DFA), proximal tibial angle (PTA) and patellofemoral alignment (PFA) correction, have not been studied as potential contributors to quadriceps strength loss after TKA.…”
