Patients with Diabetes Perform Worse after TKA

Arthritis Care Res; ePub 2018 Aug 29; Cheuy, et al

There is a negative relationship between the presence of diabetes mellitus (DM) and the recovery trajectories of all physical performance measures following total knee arthroplasty (TKA). This according to a recent study that aimed to determine if patients with and without DM differed in the recovery of 3 physical performance measures during the first 90 days following TKA. Clinicians should, therefore, closely monitor patients with DM, knowing that they are at higher risk for sustained functional deficits and early complications. Data were collected from 169 patients (37 with DM, 132 without). Physical performance measures included the 4‐meter walk (4mW) test, the 30‐second sit‐to‐stand test (30STS), and the timed‐up‐and‐go test (TUG). A mixed effects model was performed to determine differences in the rate of recovery and 90‐day postoperative scores for all measures. Researchers found:

  • Both groups had similar baseline values for all measures.
  • Patients with DM demonstrated a slower rate of recovery for the 4mW, and worse scores for 4mW, 30STS, and TUG at the end of 90 days when accounting for significant covariates.
