Balancing the Flexion and Extension Gap. Academic versus Practical Gap Balancing. We have all studied this gap balancing matrix. And conceptually it is helpful. But many of the squares in this chart recommend "augments" to treat flex-ext imbalance which is almost never done for a primary TKA in reality revision TKA is a different story.

In discussion: gap balancing or measured resection? While gap balancing and measured resection both have their proponents and detractors, the reality is that most surgeons employ a hybridization of the two techniques to establish femoral component rotation and tension soft tissues in total knee arthroplasty TKA. 28/10/2019 · Live surgery demonstrating gap balancing in both sagital and frontal planes during total knee arthroplasty.
The reported incidence of postoperative instability leading to revision TKA ranges from 13% to 33%. Implant malpositioning and malrotation of the components further complicate revision TKA stability. Regardless of the cause, flexion/extension gap balancing. balancing may cause flexion instability, flexion/extension mismatch, or residual deformity. These are common causes of patient pain, complaints, and revisions. One method to improve alignment, sizing, and balancing is a Gap Balancing technique using a tensioning device. It’s important to consider that TKA is a bone AND soft tissue operation. Gap balancing has been shown to be a successful technique for soft tissue balancing in TKA and has been used by surgeons for many years .

Principles of ligament balancing in TKA. Recent technological advances have enabled the accurate evaluation of soft tissue tension intraoperatively. 2 However, the goal of soft tissue balancing is unclear. The classical concept of TKA is the achievement of equal medial and lateral gaps as well as equal flexion and extension gaps. 13/05/2019 · Measured Resection Trumps Gap Balancing in TKA OTW Staff • Thu, August 20th, 2015.

Bony resection of the proximal medial tibia, an alternative technique for soft tissue balancing in total knee arthroplasty TKA, was compared to the conventional medial soft tissue release technique. From June 2005 to June 2007, we performed 40 TKA in 27 patients with ≥10° tibio-femoral varus deformity.
The second utilized in vivo video fluoroscopy and demonstrated a much high incidence of femoral condylar lift-off instability when a measured resection technique was used. In summary, the authors believe gap balancing techniques provide superior gap. 26/07/2019 · Dr. Bertrand Kaper, HonorHealth, Scottsdale, AZ demonstrates robotic-assisted NAVIO 7 TKA Gap Balancing workflow. The NAVIO™ Surgical System provides accuracy, flexibility and confidence using real-time imaging, hand-held robotics, a portable cart, and now supports multiple implant options for total knees including the kinematically focused. Planning at 0o resulted in larger gaps and lower joint forces at full extension, but increased knee laxity in mid-flexion which may contribute to mid-flexion instability. Depending on the clinical circumstances of the case, the implications of planning at both 0o and 10o in gap balancing TKA should be. basic principles of flexion and extension gap balancing The surgical goals of a revision TKA are the same as those of a primary TKA: restoration of alignment and stability of the joint in all planes. Similar to the primary knee arthroplasty, the principles of obtaining an equally balanced flexion and extension gaps are also the same. 27/07/2018 · Total 66 additional ligament balancing procedures were performed. Using orthosensor, we could obtain 94% quantified balance knee, consequently. And between the techniques, measured resection TKA showed less balanced knee and also required more additional procedures compared to modified gap balancing TKA.
