The purpose of our study was to investigate post operative pain management in relation to short term functional mobility in an intervention group receiving concomitant use of an IV narcotic PCA and a continuous infusion of local anaesthetic via a femoral nerve catheter CFNC compared to a group receiving narcotic PCA alone. This was a preliminary study conducted to establish an appropriate design for a larger investigative study. Methods A prospective design was used to measure the effect of a CFNC on post operative pain management and functional mobility prior to hospital discharge. The amount of fentanyl used pain and nausea scores timed up and go TUG tests and active range of knee movement AROM were used to compare a CFNC and supplemental narcotic patient controlled analgesia PCA group n 27 with a PCA only group n 25 . Results The CFNC group used significantly less fentanyl than the PCA only group p .001 but there was no significant difference in TUG times between the two groups. There was however a significantly lower AROM reported for both extension p .04 and flexion p .006 in the FNC group. Women had significantly slower TUG times p .005 and there were moderate to strong positive correlations between post operative TUG times and the preoperative TUG time rs .505 p .001 the time since oral analgesia rs .529 p .014 and pain scores rs .328 p .034 Conclusions In this small preliminary study improved TUG performance at Day 4 post op
