Silicone has been used in numerous health care roles, from catheters to finger joint arthroplasties, with proven success. Its use as an interpositional membrane for the prevention of adhesions has been attempted in various anatomic sites with unpredictable results. We present a case report of a patient with recurrent arthrofibrosis requiring multiple operative procedures including manipulations under anesthesia, arthroscopies, and unicompartmental and eventual total knee replacement. After developing stiffness after total knee arthroplasty, the patient received placement of a silicone interpositional membrane with the goal of minimizing scar formation. Arthrofibrosis recurred, and only eventual removal of the membrane and correction of the underlying overstuffed patellofemoral compartment has allowed for maintained functional improvement in motion after 3 years.
