Higher Body Mass Index Leads to Longer Operative Time in Total Knee ArthroplastyBarthelemy Liabaud MD, David A. Patrick Jr. BS, Jeffrey A. Geller MD

Deals with a retrospective registry cohort 273 patientsOperative time first incision to last sutureAlmost female 61.2% obesity overallDescribes increased complication rate for obese but does not describe their co-morbidities and so could be attributed to other factors.Significant difference in operative time between normal and obese groups I-III but not overweight. Did not demonstrate difference in WOMAC or SF12 scores.Arthrofibrosis even across groups, wound infection preponderant in obese patients.AND in this cohort the obese group were significantly younger by 6.41 years

Quantifying Cardiovascular Risks in PatientsWith Metabolic Syndrome Undergoing TotalJoint ArthroplastyKishor Gandhi, MD, MPH,* Eugene R. Viscusi, MD,* Eric S. Schwenk, MD,*Luis Pulido, MD,y and Javad Parvizi, MDy

Retrospective Cohort 8157 TJA over three years1132 had met synd 13% (would be 25% in gen pop)3000 controls chosen who did NOT have Met SyndModified definition of Met Synd presence of 3 or more of DM, Dyslip, HTN, ObesityObesity alone is not statistically significant for cv complicationsSays cumulative incidence of CV complications is 4.3% in Met synd vs 3.1% in controls but doesnt give actual figures or p-values etc for individual complications gives them as a pooled bivariate and says p-val is .028 for this the only individual cardiovascular outcome that is given an individual p-value is PE and it is 40, 41 TKRs in 38 patients with BMI
