Tibial plateau slopes in Indian patients with or without anterior cruciate ligament injury: a magnetic resonance imaging study.

Purpose: To compare anterior cruciate ligament (ACL)-injured and ACL-intact patients as well as males and females in terms of tibial plateau slopes to determine their association with ACL injury.

Methods: Magnetic resonance images (MRI) of the knee of 310 male and 179 female skeletally mature Indian patients (mean age, 40 years) with (n=170+29) or without (n=140+150) ACL injury were reviewed. Their medial and lateral tibial plateau slopes (MTPS and LTPS), medial tibial plateau depth (MTPD), and lateral tibial plateau height (LTPH) were measured using MRI.
