Since my consultant appointment in 1992 I have run a joint replacement register and have advised the government on the new national hip register. I developed the first Leeds pre-admission home screening and discharge planning of joint replacement patients in 1992 and set up a patient telephone helpline at the Chapel Allerton Hospital hip centre in 1996.In 1998, I was advisor to the British Orthopaedic Association on the 'Best practice in hip surgery'.
