title: Is socioeconomic status a risk factor for stiffness after total knee arthroplasty? A multicenter case-control study.
abstract: Socioeconomic factors may play a role in the development of arthrofibrosis following total knee arthroplasty. Using manipulation following total knee arthroplasty as a surrogate for stiffness, this multicenter case-control study found that African American and young patients (<45 years of age) had twice the odds for manipulation compared with Caucasian and older-age patients.
