Impact of different glucose metabolism status on clinical outcomes of open arthrolysis for post-traumatic elbow stiffness.

Abstract

Diabetes and prediabetes are worldwide public health problems and are considered predisposing factors for adverse functional outcomes after various orthopedic operations. The purpose of this retrospective study was to determine the impact of glucose metabolism status on functional outcomes and complications after open arthrolysis for post-traumatic elbow stiffness. The study included 152 patients with post-traumatic elbow stiffness undergoing arthrolysis, including 120 in the normoglycemic group, 21 in the impaired glucose regulation group, and 11 in the diabetes mellitus group. General patient data, functional performance, and complications were documented and analyzed. Demographic data and disease characteristics were comparable at baseline. Postoperatively, significant differences were found in range of motion and the Mayo Elbow Performance Score: the diabetes mellitus group had the poorest clinical outcomes. However, there were no significant differences in forearm rotation, visual analog scale pain scores, and complication rates. Patients with post-traumatic elbow stiffness and abnormal glucose metabolism were at increased risk of poorer outcomes after open arthrolysis, and patients with diabetes mellitus had the poorest performance. This study underlines the importance of glycemic control in patients with abnormal glucose metabolism before open arthrolysis.
