Case: A 45-year-old female patient presented with left knee pain after a ski accident. Magnetic Resonance Imaging (MRI) showed complete rupture of the anterior cruciate ligament, posterior cruciate ligament, proximal Medial Collateral Ligament (MCL), and medial patellofemoral ligament. The lateral meniscal root was torn with the posterior horn incarcerated superiorly into the popliteal hiatus, rendering high risk of plastic deformation. An unconventional 2-staged surgical approach was performed.
Conclusion: Where risk of meniscal plastic deformation is high in the setting of multiligamentous knee injury (MLKI), diagnosis and careful surgical planning are central to a successful outcome. Treatment of intra-articular structures in operative stage 1 in MLKI is possible and was necessary in this case.
