Incidence and Risk Factors of Orthostasis After Primary Hip and Knee Arthroplasty

Postoperative orthostatic intolerance following fast-track unicompartmental knee arthroplasty: Incidence and hemodynamics A prospective observational cohort study

“…The low OI incidence we report in the current study is in line with the scarce number of studies exploring OI after minor surgical procedures. A single prospective observational study reported an OI incidence of 4% after cial breast cancer surgery (9), while a recent retrospective study examining OI incidence and risk factors after knee arthroplasty only included eight UKA patients and reported OI in a single patient (17). In contrast, numerous studies have described OI incidence of 40-60% after major surgical procedures, such as total knee arthroplasty(8), total hip arthroplasty (7,24,25), laparoscopic colorectal resection (5), radical prostatectomy(6, 26), gastrectomies (27), laparoscopic gynecologic surgery(28) and various cardiothoracic procedures (28, 29).…”

“…and Fig.1. When compared to OT patients, OI patients presented with signi cantly attenuated cardiovascular responses in sitting position in SAP (11(20) vs. -4[14] mmHg; p = 0.02) and MAP (15 (13) vs. 3[17] mmHg; p = 0.04). Furthermore, OI patients presented with attenuated responses in standing position in SAP (13(22) vs -13[30] mmHg, p = 0.06), DAP (18 (15) vs 5 [16] mmHg; p = 0.10),…”

“…Furthermore, its bene ts include less bleeding, postoperative pain and opioid usage, shorter in-hospital length of stay, fewer postoperative complications and reduced cost (12)(13)(14)(15)(16)). However, minimal data exist on OI following UKA (17).…”

Adapting Physical Therapy Practice for the “Short-Stay” Total Joint Arthroplasty Patient: A Commentary

“…Thus, motor, sensory, and vital sign screening is essential to establish objective criteria for patient readiness. Temporary motor weakness surrounding the knee has been associated with certain types of anesthesia and has been found to relate to knee buckling that can result in falls and other injuries during upright activities [6,17,45]. Orthostatic hypotension is common after surgery and may also result in falling [3,17].…”

“…Temporary motor weakness surrounding the knee has been associated with certain types of anesthesia and has been found to relate to knee buckling that can result in falls and other injuries during upright activities [6,17,45]. Orthostatic hypotension is common after surgery and may also result in falling [3,17]. A standing blood pressure measurement to screen for orthostatic hypotension and a “trial” of marching in place to screen for knee buckling help establish patient readiness for walking.…”
