Abstract

Introduction

We compare the intra- and interobserver reproducibility of classifications of tibial plateau fractures most commonly used in our clinical practice. These were the AO and Schatzker classifications.

Patients and methods

Agreement was measured using kappa coefficients on the data obtained from three observers reviewing 30 fractures and these values were interpreted according to Landis and Koch.

Results

It was found that both classifications were substantially reliable with regards to intraobserver reliability but that the Schatzker system was only fairly reliable and the AO classification moderately reliable with regards to interobserver reliability. Breaking down the AO classification, with regards to intraobserver reliability, the AO group was substantially reliable and the type excellently reliable. For interobserver reliability, the AO group was moderately reliable while the AO type was substantially reliable.

Conclusion

For tibial plateau fractures seen on plain x-ray, the AO classification is more reliable between observers than the Schatzker classification.
