Review Question - QID 218112

A patient is undergoing a stage 2 revision total knee arthroplasty after clearing a periprosthetic infection. The surgeon begins their medial parapatellar approach with a longitudinal skin incision. A medial parapatellar arthrotomy is made and a standard medial release is performed to elevate the proximal-medial tibial periosteum and associated soft tissues. There is significant fibrous scar tissue throughout the intra-articular space of the knee. The surgeon performs a limited debridement to visualize the all-polyethylene tibial component of the articulating spacer. The surgeon finds the knee is incredibly stiff and cannot flex past 80 degrees. Further, they are unable to subluxate/evert the patella. Which of the following is the most appropriate next step in exposure?
