Objectives:To describe the clinical and subclinical signs for early diagnosis and evaluate the short-term outcomes of surgical treatment of popliteal artery injury in knee trauma. Materials and methods: A retrospective descriptive study was conducted on 30 patients with knee trauma and popliteal artery injury who underwent surgery at Binh Dan Hospital from August 2016 to June 2021. Results: The mean age of admitted patients was 35.5±12.8 years, predominantly male (73.3%). The majority of cases were due to traffic accidents (83.4%). Peripheral pulse was absent or decreased in 76.7% of patients. Most patients (95.3%) showed loss of flow signal on ultrasound. The most common surgical intervention was venous graft repair (63.3%). After surgery, 93.3% of patients had good flow restoration. The postoperative arterial occlusion rate was 6.7%. There were two cases that required a second surgery for popliteal artery recanalisation: one case where limb salvage was achieved, and one case that resulted in amputation. Conclusion: The application of appropriate diagnostic measures, emergency management, and surgical intervention has resulted in positive treatment outcomes, helping to reduce the rate of limb amputation and other severe complications
