Patient is an 80 year old female who had come in from out of state after being advised to receive an amputation of her left leg. Patient previously had 5 surgeries, including irrigation, debridement, and drainage of her left knee after she was involved in a car accident several years ago. Previous surgeries were performed by anout of state facility.

Patient came in with X-rays to review, as shown below. Upon examination, patient was experiencing pain and was ultimately advised to receive a left staged Total Knee Arthroplasty (TKA) Reconstruction surgery. All alternatives and options were discussed at length with the patient.

It was explained to the patient that she had a comminuted fracture in which the bone broke into many pieces and that the two options were an Open Reduction Internal Fixation (ORIF) procedure or a replacement, but was advised that the replacement was the better option to achieve better results.

femoral and tibial 1

X-Rays show osteolysis of the femoral and tibial component of the left TKA prosthesis

There is also capsular calcification and capsular distention along with severe thinning of the cortex around the upper aspect of the femur. Arrows show osteolysis of the bone.

femoral and tibial 2

X-Rays show preoperative changes of left TKA reconstruction

Patient received an aspiration of the left knee to check for infection. Results showed that the patient had an infected knee tumor prosthesis. Patient was advised to receive an articulating antibiotic prosthesis with high dose articulating antibiotic spacers to treat the infection.

Antibiotic spacers will be left in for approximately 6-8 weeks and will then be removed and replaced with a new prosthesis. Patient had decided to proceed with the surgery.

Pre-operative Scanogram show mild degenerative changes at both hips and right knee

There is an orthopedic plate and multiple screws in the right distal femur.

femoral and tibial 4

Pre-Surgical X-Rays show left TKA dislocation with dorsal translation of the tibia and widening of the tibiofemoral joint
