A 52-year-old woman sustained a direct soft tissue injury to the right knee following a fall onto the right knee. X-rays did not identify any bony injury. Physiotherapy decreased pain but instability persisted. MRI scans identified early degeneration. An orthopaedic opinion recommended total knee replacement. Following a total knee replacement, the pain has worsened and she remains functionally impaired 2 years following the surgical intervention. Knee replacements are commonly performed successful surgical interventions. The increased numbers of replacements might be due to the lowered threshold in recommending surgical intervention by health professionals. This may increase the failure rate. It also raises the question whether adequate non-operative measures were attempted?
