AUTHORS ' CONCLUSIONS Very low quality evidence is available from single trials , thus we are uncertain if hip pre caution s with or without the addition of equipment and functional restrictions are effective in preventing dislocation and improving outcomes after THA .
BACKGROUND Total hip arthroplasty ( THA ) is one of the most common orthopaedic operations performed worldwide .
Painful osteoarthritis of the hip is the primary indication for THA .
Following THA , people have conventionally been provided with equipment , such as raised toilet seats and chairs , and educated to avoid activities that could cause the hip joint to be in a position of flexion over 90 degrees , or adduction or rotation past the midline .
These aspects of occupational therapy have been advocated to reduce the risks of prosthesis dislocation .
However , the appropriateness of these recommendations has been question ed .
OBJECTIVES To assess the effects of provision of assistive devices , education on hip pre caution s , environmental modifications and training in activities of daily living ( ADL ) and extended ADL ( EADL ) for people undergoing THA .
Questionnaire on the perceptions of patients about total knee replacement.
We have developed a 12-item question naire for patients having a total knee replacement ( TKR ) . We made a prospect i ve study of 117 patients before operation and at follow-up six months later , asking them to complete the new question naire and the form SF36 . Some also filled in the Stanford Health Assessment Question naire ( HAQ ) . An orthopaedic surgeon completed the American Knee Society ( AKS ) clinical score . The single score derived from the new question naire had high internal consistency , and its reproducibility , examined by test-retest reliability , was found to be satisfactory . Its validity was established by obtaining significant correlations in the expected direction with the AKS scores and the relevant parts of the SF36 and HAQ . Sensitivity to change was assessed by analysing the differences between the preoperative scores and those at follow-up . We also compared change in scores with the patients ' retrospective judgement of change in their condition . The effect size for the new question naire compared favourably with those for the relevant parts of the SF36 . The change scores for the new knee question naire were significantly greater ( p < 0.0001 ) for patients who reported the most improvement in their condition . The new question naire provides a measure of outcome for TKR that is short , practical , reliable , valid and sensitive to clinical ly important changes over time
