Risk Factors for Predicting Risk of 30 Day Mortality After Total Knee Arthroplasty

 

Short-term mortality associated with total knee arthroplasty in the study was low at 0.21%.

 

Factors associated with increased risk of 30-day mortality:

(1) age of the patient > 70 years

(2) presence of pre-existing cardiovascular and/or pulmonary disease (hypertension, cardiac arrhythmia, coronary artery disease, congestive heart failure, myocardial infarction, valvular disease, COPD, asthma, restrictive lung disease, history of pulmonary embolism)

(3) primary surgery rather than revision

(4) simultaneous bilateral total knee replacements

(5) use of a cemented prosthesis

 

Modifiable options:

(1) use of a noncemented prosthesis rather than a cemented one

(2) opting for 2 unilateral procedures rather than simultaneous bilateral surgery
