Mar 10, 2024 · Goal is to obtain a gap that is equal in flexion and extension. This will ensure that the tibial insert is stable throughout the arc of motion. remember increasing/decreasing the size of the femoral component only changes the AP diameter and therefore affects the flexion gap only.

Jun 1, 2014 · Creation of symmetric balanced flexion and extension gaps is a surgical goal of a total knee arthroplasty (TKA). 1) Precise soft tissue balancing combined with accurate bone resections determine rotation of the femoral component.

Dec 22, 2016 · Instability is a major reason for failure of total knee arthroplasty (TKA). 1,2 During primary TKA, failure to obtain a knee that is equally balanced in flexion and extension can lead to instability. This can result in a knee that is painful and often functionally unstable.

Feb 22, 2017 · The angle of bone cuts and the surrounding soft tissue tension can both affect the balance of the flexion gap (90°) and extension gap (0°). The balance of a gap is measured with a spacer block. A balanced knee has equal sized Flexion and Extension gaps.

Mar 14, 2017 · One goal of TKA is to achieve balanced tension within the knee throughout range of motion. This balanced tension is important for implant stability and longevity. A balanced knee has rectangular Flexion and Extension gaps. A balanced knee also has equal sized Flexion and Extension gaps.

May 6, 2024 · Gap balancing versus measured resection: Achieving a well-balanced symmetric flexion and extension gap is paramount in TKA. Precise bony cuts and accurate soft tissue balancing determine femoral component rotation. Malrotation of the femoral component may result in anterior knee pain, patellofemoral joint instability, flexion gap instability ...

May 4, 2020 · In total knee arthroplasty (TKA), it is important to adjust the gap between extension and flexion and the soft tissue balance.

Introduction: The success of Total Knee Arthroplasty (TKA) hinges on balanced flexion-extension gaps. This paper aims to evaluate the correlation between imbalanced gaps and clinical outcomes, and hence help quantify the imbalanced gap in …

Jul 1, 2003 · In revision TKA, the extension gap can be reduced by augmenting the distal femur. This procedure does not change the anteroposterior dimension of the femoral component, so the flexion gap should be unaffected.

Ninety-three knees undergoing TKA with the modified gap balancing technique were included. Preoperative range of motion, intraoperative extension-flexion gap balance, thickness of the resected bone and radiological parameters were investigated.
