The Caledonian Technique ^TM has been widely accepted as a safe and effective way of improving post-operative recovery and reducing length of stay following total knee arthroplasty. In keeping with the principles of the enhanced recovery programme its use has slowly spread from specialised units into district general hospitals. There is little evidence using PROMs that supports the use of the Caledonian Technique in the DGH setting. The primary aim of this study was to find out whether the Caledonian Technique was being successfully implemented in this district general setting for TKA. The secondary aim was to identify whether there was a difference in the patients’ perspectives of success post discharge.

This is a prospective questionnaire-based cohort study of patients undergoing total elective TKA in this DGH. It was carried out at Forth Valley Royal Hospital, Larbert, Scotland between June 2011 and 2012. All patients undergoing elective TKA were asked to complete a questionnaire assessing pain, mobilisation, function and satisfaction at 6 weeks post-operatively. Case notes of all returned questionnaires were reviewed and surgeon, protocol followed (Caledonian or non-Caledonian), length of stay, analgesic requirements, discharge analgesia and complications recorded.

We have shown that length of stay, analgesic requirement and cost were all less in the Caledonian group (n=17) compared to non-Caledonian (n=17). In addition there were statistically significant increases in patients mobilising on day 1 and achieving opiate free discharge in the Caledonian group. Patient satisfaction was higher in 11 out of 12 PROMs post discharge.

This confirms that previously shown improvements in length of stay and early mobilisation seen in specialised units can also be achieved in the DGH setting. Secondly it also shows that there is no negative impact on patient satisfaction and outcomes following early mobilisation and discharge.
