Study Design
The design was an exploratory, retrospective study utilizing data from the computerized medical records system of the university-affiliated rehabilitation hospital. We collected and analyzed the data for this investigation in accordance with the procedures and policies set forth by the Human Investigation Committee at the University of Virginia (UVA).
Participants
The population sample was a convenience sample. Data from the UVA Clinical Data Repository indicated that the total UVA THA population during the
Participant Characteristics
Table 1 contains the subject characteristics for men and women. More men were heavier, were smokers, and had ischemic heart disease than women (P<.05). More men (77.75%) were insured by Medicare, whereas 17.6% were insured by private carriers. Most of the women (84.1%) were insured by Medicare and 8.5% were insured by private carriers (not shown). All other descriptors and revision etiologies were not statistically different between men and women. The comorbidities are shown in table 2. A
Discussion
To our knowledge, this retrospective exploratory analysis is the first to analyze the influence of age and sex on several outcome measures of inpatient rehabilitation after THA. There were 2 major findings of this study. First, women had lower functional capacity than men at admission and discharge regardless of age. This finding was concurrent with a longer LOS and a lower FIM efficiency in women than men during rehabilitation. Second, elderly patients (≥85y) had lower functional capacity and
Conclusions
Regardless of age or sex, all THA patients can gain substantial physical function during postoperative inpatient rehabilitation. The outcomes following inpatient rehabilitation, however, differ for men and women and those of various age brackets. These findings have implications for goal setting and rehabilitation hospital discharge planning, and may affect case management under the prospective payment system. The rehabilitation team should be aware that older women are more likely to require

Patient Designation Prior to Total Knee Arthroplasty: How Can Preoperative Variables Impact Postoperative Status?
2023, Journal of ArthroplastyPredictors of (Un)successful Same-Day Discharge in Selected Patients Following Outpatient Hip and Knee Arthroplasty
2020, Journal of ArthroplastyCitation Excerpt :These studies, however, assessed an unselected patient population and differed from the present study design, as older and obese patients were mostly excluded from OJA protocols (although the exact cutoff points for what is acceptable are highly variable in the literature) [11,13,19]. Advanced age is associated with multimorbidity, gradual physical decline, cognitive impairment, and lack of direct social support [60–62], which might negatively affect the early rehabilitation process after joint arthroplasty [56,63,64]. Obesity is recognized to be associated with higher postoperative complication (ie, superficial/deep infection and revision surgery) and readmission rates after joint arthroplasty [58,65–68].

2017, Journal of ArthroplastyCitation Excerpt :Other studies have found age and gender to be significantly associated with LOS [8-10,12], although only one of these studies used fast-track TKA [12]. The causation between female gender and LOS has been previously studied [14,15]. Vincent et al [14] quantified the functional status for surgical patients and demonstrated that women present for surgery with significantly lower functional capacity than men.

2016, Journal of ArthroplastyCitation Excerpt :This is likely due to the fact that older patients present with greater comorbidity and may thereby need longer care. Our findings are consistent with literature [16,17,19,21-24]. den Hartog et al [21] retrospectively reviewed 477 patients in a fast-track program and also found that older age was a predictor of increased hospital stay.
