Total knee arthroplasty subjects who are genotyped
All patients will have whole blood drawn for genotyping, and participate in the various assessments (psychosocial questionnaires, qualitative sensory testing, etc).
Genetic: Whole blood for genotyping
This study requires genotyping by extracting DNA from blood sample. A blood sample will be drawn once during visit 2 (day of surgery) or any other time prior to that after the signing of informed consent. Four vacutainers of which hold 8.5 mL will be drawn during this time totaling approximately 34 mL of blood which completes the genomic sampling portion of the study.
- NRS-Pain With Movement on POD 2 [ Time Frame: Postoperative day (POD) 2 ]
The primary endpoint is the pain reported by subjects, using the NRS-Pain with movement on the second day after surgery.The assumption behind this study is that certain genetic variants (e.g. single-nucleotide polymorphism (SNP) are responsible for part of total variation of certain clinical phenotypes (e.g. post-operative pain here).
Numeric Rating Score Pain Assessment (0-10 scale where 0 indicates no pain at all and 10 indicates the worst pain imaginable) on Post Op Day 2, Pain with Movement
