Outline
To explore the potential categories and influencing factors of limb swelling after total knee arthroplasty(TKA).
A total of 239 patients undergoing TKA in the department of orthopedic surgery of a tertiary grade A hospital in Jiangsu province from June 2023 to May 2025 were selected as survey participants. Baseline surveys were conducted within one week postoperatively using the General Information Questionnaire,Limb Swelling Circumference Assessment Form, Pictorial Knee Self-Assessment Questionnaire,Orthopedic Patient Functional Exercise Adherence Scale,and Social Support Rating Scale.Limb swelling severity was assessed using the Limb Swelling Circumference Assessment Form on postoperative days 1,3,and 7,as well as at 1,3,and 6 months after discharge.Growth mixture modeling was used to identify potential categories of limb swelling after TKA,and logistic regression analysis was performed to examine influencing factors.
A total of 206 patients(86.19%) completed the follow-up. Three potential categories of limb swelling were identified:high-level swelling with a high plateau(30.58%),moderate-level swelling with fluctuation (35.44%),and low-level swelling with a decreasing trend(33.98%).Logistic regression results showed that inflammation level,pain severity,knee joint function,comorbidities,functional exercise adherence,and social support were significant influencing factors of the potential categories of limb swelling after TKA(P<0.05).
Limb swelling after TKA exhibits population heterogeneity.Based on these findings,healthcare providers can implement stratified assessment and personalized interventions for postoperative swelling to improve patient outcomes in swelling rehabilitation.
