Methods
Patients aged 65e84 years with hemiarthroplasty done in a tertiary hospital during 2012e 2014 were reviewed retrospectively. AMA group included AMAs carried out during years 2012e2013, and Exeter group included cemented modular Exeter hemiarthroplasties carried out during years 2013e2014. All patients were followed-up for 2 years.
Results
The Exeter group performed significantly better in rehabilitation outcomes than AMA group in terms of mobility score, independent and outdoor walking and community dwelling. They also had less hospital service reattendances due to falls, refractures and implant-related causes. There was a trend towards lower mortality in the Exeter group with increasing duration from operation.
Conclusion
The new guidelines in replacing AMA with cemented Exeter hemiarthroplasty resulted in better patient outcomes.
