Abstract
Total knee arthroplasty (TKA) is a valuable treatment option for advanced osteoarthritis
in patients unresponsive to conservative treatments. Despite overall satisfactory
results, the rate of unsatisfied patients after TKA remains high, ranging from 5 to
40%. Different modifiable and nonmodifiable prognostic factors associated with TKA
outcomes have been described. The correction, whenever possible, of modifiable factors
is fundamental in preoperative patients' optimization protocols. Nonmodifiable factors
can help in predicting the outcomes and creating the right expectations in the patients
undergoing TKA. The goal of this review is to summarize the modifiable and nonmodifiable
prognostic factors associated with TKA outcomes.
