Abstract

Aim: To describe in detail the methodology of lower one-third calf amputation using a newly modified technique, to present the clinical outcomes, and to compare this approach with classical amputation methods.
Materials and Methods: A retrospective analysis was conducted on 850 patients who underwent lower one-third calf amputation at the Scientific Surgery Center between 2021 and 2025. Among them, 450 patients (52.9%) underwent classical amputation and were included in the control group, while 400 patients (47.1%) underwent amputation using the newly proposed modification and were included in the study group. Functional and quality-of-life outcomes were assessed using the Short Form-36 Health Survey (SF-36), EuroQol-5 Dimension (EQ-5D), and Prosthesis Evaluation Questionnaire (PEQ).
Results: Patients treated with the new modification demonstrated significantly better functional outcomes compared to those treated with classical methods. According to SF-36 and EQ-5D assessments, physical functioning, mobility, and pain indicators were significantly improved in the study group. PEQ results showed that 83% of patients reported comfortable prosthetic fitting and absence of discomfort during daily use. Overall, the new technique provided superior rehabilitation potential and improved prosthetic compatibility.
Conclusion: The newly proposed modification of lower one-third calf amputation demonstrated clear advantages over classical techniques. Patients treated with this method showed improved stump stability, better prosthetic compatibility, reduced pain intensity, and enhanced functional and social adaptation. According to SF-36, EQ-5D, and PEQ assessments, the new technique resulted in superior rehabilitation outcomes and higher quality-of-life indicators. These findings indicate that this modification is an effective and functionally oriented surgical approach that significantly improves postoperative outcomes and prosthetic potential.
