Primary Outcome Measures:

To assess the efficacy of pregabalin compared to placebo on pain following total knee arthroplasty using a subject reported assessment of worst pain. [ Time Frame: 48 hours after surgery ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Effect of pregabalin on the occurrence of opioid related symptoms [ Time Frame: Daily in hospital and then every other weekly ] [ Designated as safety issue: No ]
To evaluate the presence of neuropathic pain symptoms at 3 and 6 months post surgery [ Time Frame: 3 and 6 montns ] [ Designated as safety issue: Yes ]
Effect of pregabalin on rescue medication/opioid sparing [ Time Frame: Daily ] [ Designated as safety issue: No ]
Evaluate the effect of pregabalin at reducing post-operative pain at different time points post total knee arthroplasty [ Time Frame: Daily ] [ Designated as safety issue: No ]
To evaluate the effect of pregabalin on time to eligibility for hospital discharge and time to actual hospital discharge [ Time Frame: Daily ] [ Designated as safety issue: No ]
Evaluate the effect of pregabalin on pain interference with functional activities [ Time Frame: Baseline, Discharge, and week 2,4,6 ] [ Designated as safety issue: No ]
Evaluate safety and tolerability of pregabalin [ Time Frame: Daily in hospital and then at week 2,4,6 ] [ Designated as safety issue: Yes ]
To evaluate the effect of pregabalin on persistent post-operative pain [ Time Frame: 3 and 6 months ] [ Designated as safety issue: No ]
To evaluate the effect of pregabalin on pain-related sleep interference [ Time Frame: Daily ] [ Designated as safety issue: No ]
To evaluate the effect of pregabalin on treatment satisfaction with study medication [ Time Frame: Discharge and week 2,4,6 ] [ Designated as safety issue: No ]
To evaluate the effect of pregabalin on pre-operative anxiety [ Time Frame: Baseline, day of surgery, and daily in hospital ] [ Designated as safety issue: No ]
