Fig. 7.1 Low-dose knee CT protocol to reduce radiation dose, only regions relevant to orthopaedic and biomechanical analysis are scanned. Scanning parameters are further optimised to reduce dose yet retain…
Fig. 1 Radiographs (anteroposterior, lateral, and axial patella) of the right knee showing the cruciate-retaining fixed-bearing TKR. The patella has not been resurfaced. A patella baja position relative to the…
Fig. 12.1 Total knee replacement after 18 years of implantation with massive wear of the tibial polyethylene insert In order to improve the wear performance of TKR, local stresses need…
Level of deficiency Type of deficiency Treatment options Quadriceps muscle Palsy Functional bracing of ankle and knee to allow knee stability with heel strike and knee flexion with toe loading…
Fig. 52.1 Joint line elevation after revision TKR for infected primary TKR. Joint line elevation occurred as a consequence of attempting to match the extension space with the intraoperatively noted…
Fig. 1 Radiographs (anteroposterior, lateral) of the left knee showing a cruciate-retaining fixed-bearing TKR (Triathlon, Stryker, Switzerland). The patella was unresurfaced. The tibial TKR was slightly oversized in the mediolateral…
Fig. 1 Radiographs (anterior, lateral radiographs, skyline view) of the right knee showing a femoral and tibial cemented TKR (Emotion, Aesculap, B.Braun Medical AG, Sempach, Switzerland). A pseudo-patella baja was…
Fig. 16.1 Lateral radiograph demonstrating flexion instability with a CR TKR 1. Creating an excessive flexion gap by either undersizing the femoral component or having an excessive posterior tibial slope…
Fig. 1 Radiographs (anteroposterior, lateral and axial patella) of the left knee showing the posterior-stabilised rotating platform TKR. The patella has not been resurfaced. The TKR component position (varus-valgus) appeared…
Fig. 30.1 MRI of 75-year-old woman after posterior stabilized TKR with a zirconium femoral component. The sagittal MR image shows very little metal susceptibility artifact. The soft tissues including the…
