We present the case of a 30-year-old male who sustained a traumatic posterolateral KD with a bicondylar tibial plateau fracture, meniscal and capsular disruption, and patellar tendon and multiligament injury following a high-velocity motor vehicle accident. Due to bilateral lower-extremity deep venous thromboses, surgery was performed without a tourniquet using a single-stage combined arthroscopic and open approach. The medial meniscus, medial collateral ligament, joint capsule, and patellar tendon were repaired with suture anchors, while the lateral collateral ligament and popliteus tendon were reconstructed using an allograft. This approach achieved anatomic realignment, restored knee stability, and preserved peroneal nerve function. At three months, the patient demonstrated a full range of motion and returned to normal activity. This case highlights that complex KDs with bicondylar tibial plateau fractures can be safely and effectively managed in a single stage without a tourniquet. The described technique provides practical strategies for surgeons managing similar high-risk patients and contributes to the development of more standardized operative protocols for complex multiligament knee injuries.  \nCategories: Trauma, Anatomy, Orthopedics  \nKeywords: knee dislocation, lcl, mcl tear, multiligament injury, multiligament knee injuries, patellar tendon injury  \nIntroduction  \nKnee dislocation (KD) with concomitant bicondylar tibial plateau fracture and multiligament injury is rare, and intraoperative algorithms are poorly standardized, particularly when thrombotic risk precludes tourniquet use [1] . KDs account for approximately 0.2% of orthopedic trauma and may be accompanied by serious complications such as thrombosis or disruption of the popliteal artery and vein. They are most commonly caused by high-impact trauma to the knee, including motor vehicle accidents and sports injuries  \n[2] . These injuries pose significant clinical challenges because the combination of ligamentous and osseous disruption increases the risk of neurovascular compromise and complicates surgical planning.  \nDiagnosis is often difficult because these injuries may spontaneously reduce, and vascular injury may not be immediately suspected. Additionally, plain radiographs may be negative for acute abnormalities, including tibial plateau fractures [3] . Given these diagnostic challenges, thorough vascular assessment is essential, typically using ankle-brachial index (ABI), Doppler US, or CT angiography, with angiography often preferred  \n[4] . After vascular integrity is confirmed and the joint is reduced, MRI is used to evaluate ligamentous injury.  \nThe Schenck classification system, which categorizes KDs based","cbCaiqo0MXIXVUiH","https://ap.wps.com/l/cbCaiqo0MXIXVUiH","pdf",4532366,"English","# Abstract\n# Introduction\n## Epidemiology and mechanisms\n## Diagnosis and imaging\n## Classification and treatment considerations\n## Purpose of the report\n# Case report overview","[{\"question\":\"Why was a tourniquet not used in this surgery?\",\"answer\":\"Bilateral lower-extremity deep venous thromboses made tourniquet use contraindicated.\"},{\"question\":\"What surgical strategy was performed for the knee injury?\",\"answer\":\"A single-stage combined arthroscopic and open repair/reconstruction was done without a tourniquet.\"},{\"question\":\"How were the medial and lateral structures treated?\",\"answer\":\"Medial meniscus, MCL, joint capsule, and patellar tendon were repaired with suture anchors, while the LCL and popliteus tendon were reconstructed using an allograft.\"}]","Single-Stage Repair and Reconstruction of Multiligament Injury With Bicondylar Tibial Plateau Fracture Following Traumatic Posterolateral Knee Dislocation - A Case Report | PDF",1790738299,23]
