A flexion contracture is a mechanical block to obtaining full knee extension. The etiology of the flexion contracture can be multifactorial, related to previous trauma, advanced osteoarthritis, or inflammatory arthritis. Recurrent effusions present in a knee with end-stage degenerative joint disease tend to propagate the process.

26 Μαρ 2024 · Intraoperative steps described to correct flexion contracture were: soft-tissue balancing (in posterior and medial compartments), distal femoral resection, flexion of the femoral component, and posterior condylar resection. However, no study has investigated these factors in a global model.
A flexion deformity of the knee is the inability to fully straighten or extend the knee, also known as flexion contracture. Normal active range of motion (AROM) of the knee is 0° extension and 140° flexion.
15 Νοε 2021 · Instability is one of the leading causes of failure after primary total knee arthroplasty [1–3]. Flexion instability, which may occur with both cruciate-retaining (CR) and posterior-stabilized (PS) designs, occurs when the flexion gap is preferentially larger than the extension gap [4–6].
22 Απρ 2020 · Fixed flexion deformity at knee is common in osteoarthritic knee and is a combination of bony deformity, capsular and ligamentous deformity. It affects knee biomechanics in terms of increased forces at the patellofemoral and tibiofemoral joint.
24 Ιουλ 2023 · Outline the contraindications to total knee arthroplasty. Summarize the complications of total knee arthroplasty. Explain the importance of enhancing care coordination among interprofessional team members to improve outcomes for patients undergoing total knee arthroplasty.
Mid flexion instability may occur in knees that are considered well balanced. Flexion instability resulting from greater soft tissue laxity in flexion than extension can be treated with activity restrictions, bracing, and muscle strengthening or revision TKA.
