TKA: Measured Resection Technique
Good clinical outcomes for total knee arthroplasty (TKA) can be obtained if the soft tissues are well balanced and the prosthetic components are properly oriented, combined with joint line restoration. The correct rotational alignment of the femoral component is critical because it determines patellar groove position and flexion gap stability. Improper alignment can also induce anterior knee pain, arthrofibrosis, and torsional stress on the tibial component that could lead to wear or loosening [1–3, 7, 8].
