Abstract:
Objective:To explore latent profile categories of pain catastrophizing in total knee arthroplasty patients and analyze differences in kinesiophobia among different categories of patients.Methods:Convenience sampling was used to select 340 patients who underwent total knee arthroplasty at the First Affiliated Hospital of Zhengzhou University from January 2023 to June 2024. The Pain Catastrophizing Scale (PCS) and Tampa Scale for Kinesiophobia (TSK) were used to assess patients' pain catastrophizing and kinesiophobia on the third postoperative day. Latent profile analysis was employed to simulate and categorize PCS, and to compare the kinesiophobia among patients in different categories.Results:A total of 340 questionnaires were distributed, with 327 valid responses collected, resulting in a valid response rate of 96.18%. The postoperative PCS score for 327 patients was (34.76±7.59) , with 33.33% (109/327) achieving a PCS score ≥38. The mean scores for the three dimension (exaggeration, helplessness, and rumination) items were (2.91±0.93) , (2.33±0.84) , and (2.51±0.79) , respectively. The TSK score was (48.39±9.42) , with 50.46% (165/327) scoring above 37. Three latent categories of pain catastrophizing were identified, including "high exaggeration-helplessness-rumination group", accounting for 28.75% (94/327) ; "high exaggeration-moderate helplessness-rumination group", accounting for 39.45% (129/327) ; "moderate exaggeration-helplessness-high rumination group", accounting for 31.80% (104/327) . The TSK scores of the three groups of patients were (51.75±8.49) , (46.83±8.76) , and (49.29±9.04) , respectively, with statistically significant differences ( P<0.05) . Conclusions:Patients undergoing total knee arthroplasty exhibit distinct categorical characteristics in postoperative pain catastrophizing, with varying levels of kinesiophobia observed across different pain catastrophizing characteristics. Healthcare providers should conduct early assessments to identify patients' pain catastrophizing characteristics and deliver targeted interventions to improve pain catastrophizing and kinesiophobia, thereby promoting early postoperative recovery.
