ABSTRACT
Purpose:
To explore the effect of AFN on knee function and complications in patients after TKA.Methods:
We evaluated 150 patients undergoing unilateral TKA, specifically including 102 patients with varying degrees of AFN after selection. They were divided into four groups based on AFN grade. About 48 patients did not produce AFN, 63 patients were grade I, 29 patients were grade II, and 10 patients were grade III. All patients were followed up for 24 months, and knee function, pain, complications, and other indicators were compared between the four groups. Correlation analysis and regression analysis were used to study the relationship between AFN and other indicators.Results:
Two cases of periprosthetic fractures (PPF) occurred in our study, with an incidence of 1.35%, which did not show a significant association with AFN. The changes in knee social score (ΔKSS), Western Ontario and McMaster Universities Osteoarthritis Index (ΔWOMAC), and postoperative anterior knee pain visual analog scale (VAS) score were higher in patients with AFN than in those without. Particularly, grades II and III AFN demonstrated superior efficacy. Pearson's correlation analysis showed that AFN grade is positively correlated with both ΔKSS and ΔWOMAC (r = 0.44, P < 0.001), and AFN grade had a negative correlation with the anterior knee pain VAS (r = -0.250, P < 0.05). In linear regression analysis, AFN grade was positively correlated with both ΔKSS (ß = 5.974, 95% CI 3.968-7.981, P < 0.001) and ΔWOMAC (ß = 6.356, 95% CI 4.223-8.490, P < 0.001). Besides that, there was a negative correlation between AFN grade and anterior knee pain (ß = 5.974, 95% CI 3.968-7.981, P < 0.05).Conclusion:
Patients with grade II and III AFN who underwent TKA exhibited better knee function and lower levels of anterior knee pain post-surgery.
