Abstract:
Objective:To investigate the effect of progressive resistance training on inflammatory markers, motor function and quality of life in the elderly after total knee arthroplasty (TKA).Methods:This study was a randomized controlled trial. A total of 46 elderly patients aged≥60 years who underwent total knee arthroplasty in the Affiliated Hospital 6 of Nantong University from January 2023 to June 2024 were selected and divided into experimental group and control group by computer random number method (23 cases in each group). The control group received routine rehabilitation management intervention, progressive resistance training was added to the experimental group on the basis of the control group, and all patients were intervened for 4 weeks. Interleukin-6 (IL-6), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), 30-Second Chair Stand Test (30sCST), Knee Society Score (KSS), and World Health Organization Quality of Life Scale-Brief Form Questionnaire (WHOQOL-BREF) scores were measured at 1 day before operation, 2 weeks and 4 weeks after operation, and were compared respectively.Results:At 2 and 4 weeks after operation, the levels of IL-6 [(22.44±2.17) and (9.91±1.41) pg/ml], CRP[(19.61±2.20) and (3.17±0.40) mg/L] and ESR[(44.85±3.78) and (28.28±3.31) mm/1 h] in the experimental group were significantly lower than those in control group [IL-6: (24.65±1.77) and (11.35±1.67) pg/ml, CRP: (23.24±2.69) and (4.15±0.45) mg/L and ESR: (48.54±3.66) and (34.60±2.98) mm/1 h](all P<0.05). At 2 and 4 weeks after operation, the 30sCST[(9.87±0.92) and (11.83±1.03) times], clinical scores of KSS[(48.44±3.13) and (71.09±3.30) points], functional scores of KSS[(40.44±3.96) and (69.35±4.07) points] in the experimental group were significantly higher than those in control group [30sCST: (9.30±0.70) and (10.52±0.79) times, clinical scores of KSS: (46.17±2.86) and (67.00±2.89) points, functional scores of KSS: (38.91±3.68) and (66.30±5.05) points](all P<0.05). At 2 weeks after operation, the scores of physical health, mental health and social relations in the WHOQOL-BREF of the experimental group [(16.96±1.02), (17.96±1.46) and (6.74±0.62) points], which were significantly higher than those in the control group [(16.09±1.08), (17.14±1.12), (6.44±0.51) points](all P<0.05). There was no significant difference in the environmental condition score between the two groups. At 4 weeks after operation, the scores of physical health, mental health, social relations and environmental conditions in WHOQOL-BREF of the experimental group [(22.09±1.81), (22.17±2.19), (12.09±1.28) and (33.91±2.26) points] were significantly higher than those in the control group [(19.65±1.80), (20.39±1.95), (10.17±1.30), (31.96±2.51) points] (all P<0.05). Conclusion:Progressive resistance training can effectively reduce the inflammatory response in the elderly after total knee arthroplasty, enhance lower limb muscle strength and knee joint function, and improve the quality of life.
