ABSTRACT

No evidence based guidelines on surveillance of cemented total hip arthroplasty exist. We reviewed outcomes of this procedure from 1996 & 1997. Patients were identifed from theatre log books. Follow up data was retrieved from patient records. Evidence of radiological loosening & time of revision were recorded. Data was analysed using a ® statistical software package. We identified 425 primary total hip arthroplasties. Using radiological evidence of loosening as the end point we found an initial peak and another at 8 years. 10 year survival rate was 86%. Using revision surgery as the end point we found an initial peak & another at 8 years. 10 year survival rate was 92%. Once the patient has made it to 1 year, no follow up is required until 8 years; unless symptomatic.
