Original Question
posterior chamber cuts were performed. Trial femoral and tibial prosthesis were performed. The patient was noted to have some increased laxity and flexion. To tighten this up further, 2 mm of bone was excised off the distal femur. Inserter was upgraded to 16 mm, and with this there was good stability and flexion in extension and good alignment. The patella was then prepared for resurfacing technique. The patient had severe wear laterally, so 8 mm of bone was excised; 29-mm symmetric trial component was placed. This tracked well with the hands-off test. Box was then cut in the femur for the posterior stabilized component. Slot was cut in the tibia for the keel of the tibial component. Rotation of the tibial component was taken off of the medial third of the tibial tubercle. The joint was then thoroughly irrigated. Lug holes were then filled with bone graft from the bone trimmings. The M-1 tibia, medium femur, and 29-mm patella were then inserted; 60-mm insert was then placed and the leg held in extension until the cement was hard. Trial insert was then removed. The cement was carefully removed from the margins of the prosthesis. The actual 60-mm posterior stabilized tibial insert was placed. Locking screw was placed. The knee joint was then thoroughly irrigated. Capsule was closed with #1 Panacryl, subcutaneous tissue with 2-0 Vicryl, and skin with staples. A dressing and a Robert Jones dressing with anterior plaster splint were then applied. The tourniquet was released. Follo
