Our study reports a patient with femoral component loosening after total knee arthroplasty (TKA) using an Exactech prosthesis, later recalled due to high rates of early failure. A 75-year-old male patient underwent right total knee arthroplasty (TKA) in 2018, followed by three subsequent reinterventions without replacement of the prosthetic components. He developed pain, functional limitation, and loosening of the femoral component. Given multiple surgeries on the same knee, prior antibiotic therapy, and intraoperative findings consistent with an exuberant inflammatory process, a two-stage revision arthroplasty was indicated. During the first surgical stage, the prosthetic components were explanted, extensive debridement was performed, and an antibiotic-impregnated cement spacer was implanted. In the second stage, revision was performed using a rotating-hinge knee prosthesis. This case highlights the clinical impact of knee prostheses with manufacturing defects and emphasizes the need for annual surveillance of patients who received Exactech TKA components between 2004 and 2021.
