Peroneal nerve injuries occurred more commonly in the ULV cohort (39.1%) compared with all patients with MLIs (8.4%), as did vascular injuries (28.1% vs 4.7%, respectively). Postoperative complications were common among all ULV-MLI patients regardless of neurovascular injury status. Seventeen patients (6\/12 in the intact group and 11\/11 in the neurovascular injury group) had significant complications postoperatively. A significantly higher overall complication rate was noted in the ULV-MLI group (73.9%) compared with the entire MLI cohort (21.4%). Additionally, the ULV-MLI cohort had a higher reoperation rate, wound infection rate, deep venous thrombosis rate, and presence of vascular claudication.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Ultra-low velocity knee injuries occur in patients with a greater BMI, more frequently in female patients, and with higher rates of concomitant neurovascular injuries compared with other MLIs.
