title: The Utility of Increased Constraint in Primary Total Knee Arthroplasty for Obese Patients.
abstract: Total knee arthroplasty (TKA) for obese patient entails more preoperative comorbidities and complications, and shorter longevity. This article is a retrospective review comparing longevity of the constrained implant with a standard prosthesis. Patient-specific data, Knee Society Scores, complications, and revisions were recorded and compared. No statistical differences were found. The constrained condylar knee for obese patients improves the intramedullary alignment of the prosthesis and supports the surrounding soft tissues. The clinical results are similar to a standard implant in the nonobese with similar longevity at midterm follow-up.
