Figure 2 Intraoperative image of the right knee, through a medial parapatellar approach, showing the patella retracted to the right-hand side of the picture with 2 pins secured in the patellar tendon. On the left, a Hohmann retractor is used for soft-tissue retraction. The femoral component is retracted using another Hohmann retractor. Pus can be seen over the tibial component (tibial tray) that was mostly being drained from the posteromedial aspect of the knee.
