Diabetes mellitus has a global impact, necessitating surgical intervention when conservative methods fail. Transtibial amputation (TTA) is commonly performed on diabetic patients, yet surgical site complications can lead to more procedures. This study aimed to identify factors linked to wound healing issues post-TTA in diabetics.A total of 181 patients who underwent TTA between 2004 and 2021 at a single hospital were included in the study. Exclusion criteria comprised trauma, non-diabetic mellitus, follow-up duration of less than 1 year, incomplete medical records, and surgeries performed by different surgeons. The comparison focused on underlying diseases other than diabetes between the group with wound problems and the group without. Additionally, factors impacting blood flow, such as presurgery hemoglobin levels, intraoperative blood transfusion, the use of antithrombotic or anticoagulant drugs, and the presence of procedures like percutaneous transluminal angioplasty (PTA) and bypass surgery, were analyzed.Among the 181 cases, 22.1% experienced problems at the surgical site while 77.9% did not. Statistical analysis revealed that age was a significant variable affecting wound healing problems after TTA in diabetic patients (p = .007). However, there were no significant differences in wound problems based on comorbidities other than diabetes (p = .209), gender (p = .677), preoperative anemia (p = .102), intraoperative blood transfusion (p = .633), the use of antithrombotic or anticoagulant medications (p = .556), and the performance of PTA or bypass surgery (p = .6).In conclusion, this study found that age was a significant variable affecting wound healing problems after TTA in diabetic patients. Although no association was observed between underlying diseases and wound healing problems, further investigation and cautious management of factors such as preoperative anemia, intraoperative blood transfusion, the use of antithrombotic or anticoagulant drugs, and the performance of PTA or bypass surgery are warranted to prevent complications and optimize wound healing outcomes in diabetic patients undergoing TTA.
