case_images: Preoperative images of the right knee. (a, b) Anteroposterior (AP) radiograph of Schatzker type V tibial plateau fracture. (c, d) AP radiograph of valgus knee osteoarthritis 8 years following osteosynthesis. (e) Standing whole-leg plain radiographs. Blue line indicates mechanical axis of right lower limb.

case_images: Score (FJS; 0-100 as worst to best)   was 25. She had undergone internal fixation using locking compression plate (LCP)-MPTP and LCP-PTP (DepuySynthes, Solothurn, Switzerland) to treat Schatzker type V tibial plateau fracture due to a fall from height 8 years before admission (Figure 1).
case_images: Three-dimensional templating showing that at least eight proximal locking screws required removal during tibial bone resection. (a) Anteroposterior and (b) Lateral view.

case_images: TN, USA)   revealed that at least eight proximal locking screws inserted into medial and lateral LCP required removal during tibial bone resection using a cutting guide following the application of the proximal lateral tibial fitting PSI for the lateral approach (Figure 2). Therefore, PSI-assisted MA-PS TKA, followed by partial screws and LCP removal   was planned.
case_images: Distal femoral and proximal tibial osteotomies with patient-specific instrumentation. (a) Femoral osteotomy via lateral parapatellar approach. (b and c) The locking plate placed on the proximal-anterolateral tibia had to be removed so that the lateral tibial PSI could be placed on the proximal lateral tibia. The blue arrows indicate that the locking plate was interfering with the pin insertion. (d and e) Fat flapping was performed to cover the capsule defect due to lateral release before incision closure.
