RESUMO
Context: Periprosthetic joint infections (PJIs) are a rare but highly destructive complication after total knee arthroplasty (TKA). Nursing plays an important role in preventing postoperative infections in patients, but different nursing modes have different rates of postoperative infections. Objective: The study intended to explore the effects of "encouragement, education, exercise, employment, and evaluation" (5E) rehabilitation nursing on the prevention of periprosthetic joint infections (PJIs) after TKA. Design: The research team conducted a randomized controlled trial. Setting: The study took place at the First People's Hospital of Huzhou in Huzhou, China. Participants: Participants were 80 TKA postoperative patients at the hospital between January 2023 and July 2023. Interventions: The research randomly divided participants into two groups: (1) the intervention group, the 5E group, with 40 participants and (2) the control group, with 40 participants. The control group received routine nursing, while the 5E group received 5E rehabilitation nursing. Outcome Measures: The research team examined: (1) the prosthesis' location; (2) wound healing; (3) score for knee joint function, using the Berg Balance Scale (BBS) and the Hospital Score for Special Surgery (HSS) of the knee joint; (4) postoperative level of inflammatory factors, using levels of C-reactive protein (CRP); (5) infection occurrence; (6) length of hospital stay; and (7) nursing satisfaction. Results: The prosthesis was well positioned in both groups. Compared to the control group, the 5E group's: (1) wound healing was significantly better (P < .001); (2) at 7 days after surgery, HSS score (P < .001) and BBS score (P < .001) were significantly higher; (3) C-reactive protein (CRP) levels were significantly lower (P < .001); (4) at 90 days after surgery, incidence of postoperative periprosthetic joint infection (PJI) was significantly lower (P < .001); (5) length of hospital stay was significantly shorter (P = .0013); and (7) nursing satisfaction was significantly higher (P = .0338). Conclusions: The 5E rehabilitation nursing for patients after TKA was helpful in promoting wound recovery, supporting the recovery of knee-joint function, reducing the incidence of PJIs, shortening the length of hospital stay, and improving patients' nursing satisfaction.
