Failed knee replacement: incorrect indication?
1School of Medicine, University of Liverpool, Liverpool, UK.
Abstract:
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?

Knee Exam
The knee is a hinged joint that connects the femur with the tibia. It is the largest joint in the body, and due to its location in the middle of the lower leg, it is subjected to a variety of traumatic and degenerative forces. Examination of the knee can be quite complex, owing to the fact it is an inherently unstable joint held together by various ligaments and supported by menisci, which act as shock absorbers and...
