Physical Function following Total Knee Arthroplasty in Patients with Diabetes Mellitus

Patients with diabetes mellitus (DM) historically have a higher risk for complications and poorer outcomes following total knee replacement when compared to patients without diabetes. Previous studies have identified preoperative factors in patients with DM that significantly contribute to postoperative complications and poor functional outcomes. In this retrospective study, the functional outcomes of total knee replacement patients with and without diabetes will be compared. Investigators will examine the effects of preoperative and postoperative risk factors in DM patients. Factors to be investigated include BMI, comorbidities, preoperative patella height, postoperative patella height, postoperative pain management protocol, length of stay, and rehabilitation program type. The results of this study can be used to form guidelines to improve total knee replacement clinical and functional outcomes for patients with diabetes.
