Abstrakt: Background and Objectives: It has been shown that total knee replacement improves functional capacity and physical activity; however, the influence of age remains unclear. The objective is evaluate the pre and postoperative physical activity measured with the Knee Society Score (KSS) score and the Tegner score.
Materials and Methods: A retrospective cohort analysis was conducted on patients who underwent total knee replacement (TKR) between January 2016 and December 2019 at our institution. Demographic variables (age, sex, and body mass index), activities of daily living, age-adjusted Charlson Comorbidity Index, American Society of Anesthesiologists score, the Knee Society Score (KSS) in its clinical (KSSc) and functional (KSSf) subscales, the Tegner functional scale, activity variables from the 2011 KSS version, and pain assessment using the visual analog scale were collected. Differences in these variables were analyzed between two age groups: group A (between 65 and 79 years old) and group B (80 years or older).
Results: A total of 450 patients were evaluated (group A=245, group B=167). Group A showed a Tegner improvement of 1.19 (95% CI: 1.06-1.31), whereas group B averaged 0.61 (95% CI: 0.43-0.80) (P<.001). Age >80 was an independent risk factor for less Tegner improvement. In KSSc, group A improved by 43 points (95% CI: 40.82-46.14), while group B showed a greater increase of 53 points (95% CI: 49.74-57.80). Adjusted for confounders, those>80 showed significantly higher KSSc improvement (12.8 points). For KSSf, group A improved by 33.91 points (95% CI: 31.07-36.75), and group B by 15.57 points (95% CI: 11.78-19.35). Adjusted for confounders, patients >80 had less improvement than those <80 (19 points).
Conclusions: Patients who underwent TKR experienced improvements in physical and functional activity parameters. While these improvements were seen in the entire population, they were most notable in patients younger than 80 years.
