Orthopaedic Surgery
Aims of Joint Replacement = relief of pain and restoration of function

Life Expectancy Hip and knee surgery – improves quality of life
Mortality – risk with any operation.......
Major surgery : mortality risk 0.2%
Main causes are CVA accidents / pulmonary emboli / arrhythmia / myocardial infraction / renal failure / multi system failure

Is failure to RTW a failure of surgery ?? Many factors : motivation /poor job
satisfaction / claim culture ??
Sometimes - of course if there is a complication
After joint replacement 5% of patients suffer a complication of some sort

Complications that will affect morbidity Infection - 0.8% DVT and PE - 2% Dislocation - 2% Leg lengthening discrepancy Muscle weakness Neuro vascular injury Long term failure

Registries
“Clear trend towards the use of uncemented fixation – with an increase from 2.6% to 12% between 2001 and 2007”
“The use of uncemented prostheses has produced an increased risk of revision”.
“There is no trend towards improvement in the cohort undergoing surgery during the most recent ten years”.
“Uncemented fixation also increases the risk of serious problems during the first two years, predominantly loosening and fracture”.
“The uncemented cup has a significantly increased risk of being revised”
