A lipohaemarthrosis seen on Horizontal beam lateral X-ray in acute knee injury is often considered predictive of an intra-articular fracture requiring further urgent imaging. We retrospectively searched a five-year X-ray database for the term “lipohaemarthrosis”. We excluded cases if the report concluded “no lipohaemarthrosis” or “lipohaemarthrosis” AND “fracture”. All remaining cases were reviewed by an Orthopaedic Consultant with a special interest in knee injuries (AD) blinded to the report. X-rays were excluded if a fracture was seen, established osteoarthritic change was present, a pre-existing arthroplasty present or no lipohaemarthrosis present. Remaining cases were then studied for any subsequent Radiological or Orthopaedic surgical procedures.Abstract
