Description
This matched cohort study compares the outcomes and surgical characteristics of total knee arthroplasty in patients with a history of knee dislocation versus those undergoing total knee arthroplasty for osteoarthritis. The results of this study demonstrate statistically significantly longer operating room and tourniquet times, as well as increased use of constrained and stemmed implants compared to those undergoing total knee arthroplasty for osteoarthritis. Patients undergoing total knee arthroplasty after knee dislocation also trended toward and higher rates of postoperative complications and revision surgery, although this did not reach statistical significance.
