There is a posterior stabilized component (PSC) with removal of the posterior cruciate ligament. There is also a surgical drain and skin staples in place.

68 year-old woman treated for severe left knee osteoarthritis
This replaced a loose prior total knee arthroplasty. The patellar button was left in place. A surgical drain is in place, and there is subcutaneous gas from the recent surgery.

Interference (Kurosaka) screws are used to anchor anterior cruciate ligament graft in femoral and tibial metaphysis. Note the multiple osteochondromas (familial exostosis).
AP and lateral views of the knee show a distal femoral cadevaric limb sparing allograft approximated to the native distal femoral stump by a retrograde intramedullary nail. Two interlocking cannulated screws go through the distal portion of the nail. Cruciate ligament and capsular reattachment were performed with two interference screws and two staples in the proximal tibia and a staple in the posterior aspect of the allograft metaphysis. The patient had a non-specified distal femur sarcoma.
