This study aimed to investigate the effect of diabetes mellitus (DM) on knee extension/flexion angle and its early clinical course after total knee arthroplasty (TKA).
Patients who received TKA were retrospectively divided into two groups based on haemoglobinA1c level; the DM group (23 knees) and the control group (23 knees matched for baseline characteristics). The passive knee extension/flexion angle, gait speed and Japanese Orthopaedic Association (JOA) score were evaluated preoperatively and at 1, 6 and 12 months postoperatively.
There was no significant difference in the passive knee flexion angle at 1 and 6 months postoperatively between the groups (
Patients with DM are likely to experience passive knee flexion angle exacerbating from 1 to 6 months after TKA.
