## TL;DR

A new two-step surgical method successfully treated a rare knee dislocation by reconstructing two ligaments, offering a promising approach for similar cases.

## Contribution

The paper introduces a novel two-staged surgical protocol for bicruciate ligament reconstruction in postero-lateral knee dislocation.

## Key findings

- A staged approach with initial reduction and delayed reconstruction improved functional recovery.
- Bicruciate ligament reconstruction enabled satisfactory joint mobility and daily activity resumption.
- The method shows potential for broader application in complex knee dislocation cases.

## Abstract

This paper details a novel two-staged surgical approach to managing postero-lateral knee dislocations, a rare and challenging clinical scenario. Our case study highlights the successful application of a bicruciate reconstruction of both the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL), which has not been extensively documented in existing medical literature. The treatment protocol initiated with urgent surgical reduction followed by a delayed reconstruction, allowing for initial soft tissue stabilization. This method provided significant functional recovery, enabling the patient to resume daily activities with satisfactory joint mobility. The outcomes of this unique surgical strategy demonstrate its effectiveness and the potential for broader application, suggesting that staged bicruciate reconstruction may represent a valuable option in selected cases of complex knee dislocation. This case contributes a new perspective to the orthopedic field, advocating for further research into staged reconstruction techniques.
