Andrew J. Sheean

About

Andrew J. Sheean is a leading orthopedic researcher whose work centers on the biomechanics of the knee, with a particular focus on meniscal pathology and anterior cruciate ligament (ACL) injuries. His major contributions lie in elucidating the complex interplay between meniscal lesions and knee stability, especially regarding ramp lesions—tears at the meniscocapsular junction that often accompany ACL tears. In a highly cited 2019 study (59 citations), Sheean demonstrated how repairing these ramp lesions significantly alters knee kinematics and bony contact forces, providing critical evidence for surgeons debating whether to repair or leave these lesions untreated during ACL reconstruction. His work on lateral meniscal allograft transplantation (MAT) (36 citations) further advanced the field by comparing bone block and suture-only techniques, showing that while both methods partially restore knee function, neither fully replicates native knee mechanics. This research has direct clinical implications for patients who have undergone meniscectomy and seek joint preservation. Sheean’s biomechanical studies, often conducted using cadaveric models, have become essential references for sports medicine surgeons aiming to optimize surgical outcomes and preserve long-term knee health.
