Doppler Ultrasound Diagnosis

Total knee arthroplasty (TKA) is an effective treatment for end-stage knee osteoarthritis; however, postoperative complications-particularly wound healing problems-remain a significant concern. Chronic venous insufficiency (CVI) is associated with venous hypertension, impaired microcirculation, and tissue hypoxia, which may negatively affect wound healing and increase complication rates. This prospective observational cohort study aims to evaluate the impact of preoperative CVI on postoperative outcomes following TKA. Patients will be assessed preoperatively using the CEAP classification and Doppler ultrasonography to identify and stratify venous insufficiency. Participants will be followed for 12 months postoperatively. The primary outcome will be wound healing complications in the early postoperative period. Secondary outcomes will include functional outcomes assessed by the Knee Society Score (KSS), patient-reported outcomes using the WOMAC score, and overall complication rates. The findings of this study are expected to clarify the role of venous insufficiency as a potential risk factor in TKA and may contribute to improved preoperative risk stratification and postoperative management strategies.

In cases with breast masses, Doppler resistive index values will be calculated for the mass and surrounding healthy tissue and the opposite healthy breast tissue, and their effect on distinguishing between benign and malignant masses will be evaluated.
