Clinical outcomes of Schatzker type II tibial plateau fractures using joint depression morphology: A cross-sectional study.

Abstract

Tibial plateau fracture is a common intra-articular fracture caused by axial compression and Varus or Valgus force. This study aimed at the relationship between Luo classification morphology of tibial plateau fractures with clinical outcomes and surgical complications. The cross-sectional study was conducted on patients with Schatzker type II tibial plateau fracture who underwent surgery between May 2018 and January 2021. Clinical outcomes were measured by the AKSS, VAS, Lysholm score, alignment, and ROM. A total of 65 patients with a mean age of 36.38 years were enrolled. There was a significant difference in AKSS (p=0.001), VAS score (p=0.011), and mechanical axis alignment (p=0.037) between the groups by pre-operative joint depression depth below and above 10 millimeters. The higher pre-operative or post- operative size of joint depression depth in patients with Schatzker type II tibial plateau fractures was associated with poor outcomes, more pain, and malalignment. A higher surface area of joint depression was associated with a lower clinical outcome score and more pain.
