6. Incisión
Fig Medial parapatellar retinacular approach

7. Disección de Planos
Fig Medial capsule and deep portion of MCL are elevated subperiosteally. (Redrawn from Krackow KA: The technique of total knee arthroplasty, St Louis, 1990, Mosby.)

8. Disección de Planos Profundos
Fig Lateral patellofemoral plicae are cut to allow mobilization of extensor mechanism. (Redrawn from Krackow KA: The technique of total knee arthroplasty, St Louis, 1990, Mosby.)

9. Disección de Planos Profundos
Fig Subvastus approach involves lifting entire extensor mechanism off medial intermuscular septum and subluxing it laterally for exposure. (Redrawn from Insall JN: Surgical approaches. In Insall JN, ed: Surgery of the knee, ed 2, New York, 1993, Churchill Livingstone.)

10. Ejes de Alineamiento a nivel de linea intercondilea
Fig Alignment axes in knee with normal condylar shape. Resection perpendicular to anteroposterior axis (AP) or parallel to epicondylar axis (epi) results in resection line (x) that is slightly externally rotated relative to posterior condylar axis (PC). This results in correct positioning of the femoral component. (From Arima J, Whiteside LA, McCarthy DS, White SE: J Bone Joint Surg 77A:1331, 1995.)

11. Disección de Planos Profundos
Fig Midvastus approach shown as dotted line with right knee in 90 degrees flexion. (Redrawn from Engh GA, Parks NL: Clin Orthop 351:270, 1998.)

12. Reclinamiento Lateral de Abordaje
Fig Rectangular flexion gap is obtained by externally rotating cutting jig of femur parallel to cut surface of tibia while collateral ligaments are under equal tension.

13. Sección de Componente Femoral
Fig A, Chamfer cuts complete distal femoral resection in cruciate-retaining arthroplasty. B, Intercondylar notch cut to accommodate post and cam mechanism in cruciate-substituting arthroplasty.

14. Cortes de Componente Femoral conservando LCP
Fig PCL may act as central tether and require lengthening or release. (Redrawn from Krackow KA: The technique of total knee arthroplasty, St Louis, 1990, Mosby.)

15. Reparación de LCM
Fig Advancement of femoral origin of MCL and fixation in medial epicondyle with screw and washer. (Redrawn from Krackow KA: The technique of total knee arthroplasty, St Louis, 1990, Mosby.)

16. Sección de LCP
Fig PCL can be "recessed" by releasing it from superior surface of tibia and proximal portion of its posterior tibial attachment.
