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.

RESULTS

The ACL-injured and ACL-intact groups were comparable in terms of MTPS (6.72º vs. 6.73º, p=0.07), LTPS (5.68º vs. 5.70º, p=0.09), MTD (1.74 vs. 1.73 mm, p=0.356), and LTH (2.21 vs. 2.22 mm, p=0.393). Males and females were also comparable in terms of MTPS and LTPS in both ACL-injured and ACL-intact groups.

CONCLUSION

ACL-injured and ACL-intact patients as well as males and females were comparable in terms of the tibial plateau slope parameters.
