REVIEW OF KNEE MRI SCAN REPORTING IN YOUNG ADULT PATIENTS WITH SIMPLE FIRST-PRESENTATION SOFT-TISSUE PROBLEMS SHOWS SIGNIFICANT DISCREPANCIES IN ABNORMALITY IDENTIFICATION BETWEEN KNEE SURGEONS AND RADIOLOGISTS

The British Association for Surgery of the Knee (BASK) May 2023 Meeting, London, England, 16–17 May 2023.



Abstract

Abstract

Introduction

MRI scanning is the establish method of defining intra- and extra-articular diagnoses of patients with non-arthritic knee problems. Discrepancies in reporting have been noted in previous historic studies and anecdotally. The aim of this study was to analyse the reporting of intra-articular pathology and discrepancies in knee MRI reports by two clinician groups, consultant radiologists and consultant knee surgeons in a district hospital setting.

Methods

A retrospective case-controlled cohort study was conducted using data collected from an outpatient physiotherapy-led knee clinic. Seventy-four patients in the cohort were referred for an MRI scan of their knee(s) following a clinical examination and history. MRI reports from both the consultant knee surgeon and the radiologist were entered into a database with other clinical details. Reports were analysed to determine number of diagnoses and degree of agreement. Each report was deemed to either completely agree, completely disagree or partially agree.

Results

87 knees were scanned in total. Of the 87 reports, 14% (n=12) completely agreed. 45% of the reports (n=39) partially agreed and 41% (n=36) completely disagreed. Of the reports which partially agreed 79% (n=31) had a percentage agreement of ≤ 50%.

Conclusions

This study reveals major discrepancies in knee MRI reporting by two clinician groups. This has greatest clinical impact on non-surgical clinicians and those with limited MRI reviewing experience who are reliant on reports to describe diagnoses to patients and determining management plans. More research is required to determine the reasons for these differences and measures to mitigate them.
