Predictors of Facility Discharge, Range of Motion, and Patient-Reported Physical Function Improvement After Primary Total Knee Arthroplasty: A Prospective Cohort Analysis.

ABSTRACT: Patients are discharged to home or inpatient settings after primary unilateral total knee arthroplasty (TKA). Few studies have compared patient outcomes following these 2 rehabilitation models for TKA patients. We identified predictors of inpatient discharge, 3-month postoperative range of motion (ROM), and 3-month postoperative patient-reported physical function improvement (Veterans RAND 12-Item Physical Component Score [PCS]) between these discharge settings.We studied prospectively collected cohort data for 738 TKAs between April 2011 and April 2013 at a high-volume tertiary academic medical center in a rural setting. All patients followed a standardized care pathway that involved prospective data collection as part of routine clinical care. Adjusting variables included age, sex, preoperative PCS, surgeon, modified Charlson Comorbidity Index, preoperative body mass index, laterality, and preoperative ROM; the 3-month models also included length of stay and discharge disposition as adjusters.Significant adjusted predictors of inpatient discharge included older age, female sex, surgeon, comorbidity, lower PCS, and body mass index greater than 40. Only lower preoperative ROM predicted postoperative ROM. Inpatient discharge and higher preoperative PCS predicted lower PCS improvement. Home-based rehabilitation was associated with greater 3-month PCS improvement and showed no difference with 3-month ROM.Discharge to home-based rehabilitation after TKA, rather than inpatient facility, is associated with higher physical function at 3 months postsurgery and shows no difference with 3-month ROM. Total knee arthroplasty inpatient discharge should be based on patient care requirements rather than perceived benefit of improved ROM and physical function.

Project description:PurposeThe aim of this systematic review was to investigate the clinical and functional knee outcomes after Verasense sensor-assisted total knee arthroplasty (VA TKA), and to compare these outcomes, where possible, with those from manually balanced total knee arthroplasty (MB TKA).MethodsA systematic literature search following PRISMA guidelines was conducted on PubMed, Embase, Medline and Scopus from the beginning of January 2012 until the end of June 2022, to identify potentially relevant articles for this review. Selection was based on the following inclusion criteria: full text English- or German-language clinical studies, published in peer-reviewed journals, which assessed clinical and functional outcomes following VA TKA. Not original research, preprints, abstract-only papers, protocols, reviews, expert opinion papers, book chapters, surgical technique papers, and studies pertaining only to unicondylar knee arthroplasty (UKA) or patellofemoral arthroplasty (PFA) were excluded. Several scores (Knee Society Score [KSS], Oxford Knee Score [OKS], Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC], Knee injury and Osteoarthritis Outcome Score-4 subscales [KOOS4] and Physical Function-Computerised Adaptive Testing [PF-CAT]), alongside postoperative measurements of range of motion [ROM], reoperation rates and the rate of manipulation under anaesthesia [MUA]) were used to evaluate clinical and functional outcomes. The quality of included papers, except randomised control trials (RCTs), was evaluated using the Methodological Index for Non-Randomised Studies (MINORS). For the assessment of included RCTs, the Jadad Scale was used.ResultsThe literature search identified 243 articles. After removing duplicates, 184 papers were included in the initial screening process. Fourteen of them met all the inclusion criteria following the selection process. Mean MINORS for non-comparative studies value was 11.5 (11-12), and for comparative studies 18.2 (13-21). Mean Jadad Scale score was 3.6 (2-5). Outcomes from a total number of 3633 patients were evaluated (mean age at surgery 68.5 years [32-88 years]). In terms of clinical outcomes, the overwhelming majority of studies observed an improvement after VA TKA, but no statistically significant difference in ROM and reoperation rate when compared to MB TKA. On the other hand, lower rates of MUA have been described in the VA TKA group. An increase in postoperative clinical and functional scores values, when compared to the preoperative ones, has been reported in both groups, although no statistically significant difference between them has been observed.ConclusionThe use of Verasense pressure sensors in TKA leads to no significant improvement in ROM, reoperation rate or functional outcomes, when compared to the standard manually balancing technique. However, lower rates of MUA have been described in the VA TKA group. These findings highlight the importance of tools being able to measure ligament stresses or joint pressure for achieving an optimally balanced knee.Level of evidenceIII.
