Abstract

Purpose: We aimed to investigate the relationship between the change in knee disability and change in functional status from before bilateral total knee arthroplasty (TKA) to discharge in geriatric patients.
Methods: We retrospectively analyzed the data of 88 patients who underwent bilateral TKA. Before surgery and at discharge, the knee disability and functinal status of the patients were assessed using the Hospital for Special Surgery (HSS) knee score and the Iowa Level of Assistance Scale (ILAS), respectively. The Spearman correlation test was used to assess the correlation between the change in the HSS knee score and the change in the ILAS score.
Results: A statistically significant difference was found in the HSS knee score between before surgery and at discharge (p<0.05). No statistically significant difference was found in the ILAS score (p>0.05). A moderate relationship was found between the change in the HSS knee score and the change in the ILAS score (r = –0.48, p<0.05).
Conclusion: The change in knee disability from before surgery to discharge does not reflect the change in functional status in geriatric patients who underwent bilateral TKA.
