Can knee replacements be assessed by post?

The audit of knee replacement surgery requires long-term follow-up. The aim of this Bristol study was to examine whether an accurate assessment of knee replacement surgery could be undertaken by post, thus obviating the need for patients to visit hospital. A patient's questionnaire was designed to complement the clinic therapist's assessment form currently in use, and this was completed by 73 patients without supervision prior to the therapist's assessment. A comparison of the two assessments shows a significant discrepancy between their results, particularly in the assessment of pain, walking distance, and range of movement. The authors conclude that postal follow-up of knee replacements should be viewed with caution.
