Knee joint function, walking ability and quality of life within 6 weeks after total knee arthroplasty: A prospective cohort study

Abstract

Aims and objectives:To track changes in patients' knee function, walking ability and quality of life (QOL) before and after knee arthroplasty surgery and explore factors that influenced these parameters.Background: The number of days as an inpatient for those who undergo joint replacement operations has been greatly reduced in recent years. However, it remains unclear whether shortening the inpatient time has affected patients' recovery or their QOL.Design: Prospective cohort study. Method:In total, 101 participants who underwent total knee arthroplasty (TKA) were enrolled, with data collected preoperatively and at the 2nd and 6th weeks postoperatively. We followed the STROBE checklist to ensure the rigour of our study.Results: Forty-nine participants underwent unilateral TKA (UTKA; 48.5%), and 52 underwent simultaneous bilateral TKA (SBTKA; 51.5%). At the 2nd week postoperatively, knee joint function was significantly worse than that preoperatively. However, these patients did not exhibit significant differences in the EQ-5D utility index (EQ-5D UI) compared to their preoperative scores. At the 6th week postoperatively, the knee joint function and EQ-5D UI were significantly better than preoperative values. Participants who underwent UTKA scored higher on the Oxford knee score (OKS) than did SBTKA participants. However, no significant differences were noted between the two groups for the knee flexion angle, the timed up and go (TUG) test, or the EQ-5D UI score. Conclusions and suggestions:At the postoperative 6th week, participants exhibited improved knee joint function and QOL, but there was no difference in the walking ability compared to preoperative values. At the 6th week after surgery, patients who underwent SBTKA exhibited poorer joint function than did those who underwent UTKA.Relevance to clinical practice.: These results can assist nursing staffs and serve as a reference for providing patient education and nursing intervention to TKA patients.

Contamination Rate of Burnt Necrotic Tissue after Electrocoagulation in Total Knee Arthroplasty

“…Depending on the surgeon's preference, multiple BNT specimens (3)(4)(5) were randomly collected during the operation in the surgical field. After collection, these specimens were placed in a sterile container and immediately sent to the microbiology department.…”

“…1,2) However, periprosthetic joint infection (PJI) is a common catastrophic complication of TKA. 3) It is consequently one of the common causes of revision arthroplasty 4) and the leading cause of morbidity after TKA, with the mortality rate ranging from 2.7% to 18%. 5) The estimated incidence of PJI after TKA is between 1% and 2%.…”

Clinical prediction rule for early recovery of knee range of motion after total knee arthroplasty: A prospective cohort study

“…Although individuals undergoing TKA can begin walking with a T-cane in the early postoperative phase, they need to perform physical therapy after discharge for complete recovery of knee ROM 11,12 ) . In a previous study evaluating the recovery of knee joint function after TKA, the knee joint flexion angles measured on postoperative day (POD) 14 were significantly worse than the preoperative measurements 13) . POD 14 is a crucial time for individuals to resume ADL where the goal is to increase activity gradually.…”

The impact of preoperative muscle strength on postoperative walking ability in patients undergoing total knee arthroplasty

“…KOA makes it difficult to walk and climb stairs because of pain and joint deformity [2,3]. Total knee arthroplasty (TKA) can effectively treat KOA, thereby expanding the life space and enhancing the patient's quality of life (QOL) [4,5]. As the population ages, the number of TKAs required for KOA patients is expected to increase [6].…”
