Combined Anterior Cruciate Ligament Reconstruction With Bone‐Patellar Tendon‐Bone Autograft and Anatomical Lateral Collateral Ligament and Proximal Tibiofibular Joint Reconstruction Using Semitendinosus Allograft

Abstract Multiligamentous knee injuries involving anterior cruciate ligament rupture and lateral‐sided instability, including proximal tibiofibular joint instability and lateral collateral ligament deficiency, present unique challenges in restoring knee stability. This Technical Note describes a reproducible surgical technique for anatomic reconstruction of the anterior cruciate ligament using a bone‐patellar tendon‐bone autograft and combined lateral collateral ligament and proximal tibiofibular joint reconstruction using a single semitendinosus allograft. Emphasis is placed on proper graft orientation, tunnel placement, and sequential fixation to restore stability in both anterior‐posterior and medial‐lateral planes of the knee.
