Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

High-flexion total knee arthroplasty allows greater knee bending, benefiting specific activities and patient needs. Design and surgical advancements enhance deep knee flexion capabilities.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • High-flexion total knee arthroplasty (TKA) aims for knee flexion exceeding 125 degrees.
  • Enhanced range of motion is crucial for specific daily activities, cultural practices, and certain occupational demands.
  • Patient-specific factors like preoperative motion, BMI, and prior surgery influence outcomes.

Purpose of the Study:

  • To review advancements in high-flexion total knee arthroplasty.
  • To explore component design modifications and surgical techniques enabling deeper knee flexion.
  • To summarize the demonstrated benefits of high-flexion TKA.

Main Methods:

  • Analysis of component design modifications: posterior condyle curvature, posterior offset, tibial insert recess, trochlear groove length, and cam-post design.

Treatment of Ankle Osteoarthritis with Total Ankle Replacement Through a Lateral Transfibular Approach

Published on: January 24, 2018

  • Evaluation of surgical techniques: soft tissue balancing, component positioning, osteophyte removal, and flexion gap management.
  • Review of outcome studies on standard and high-flexion TKA designs.

    • Main Results:

    • Component modifications facilitate greater femoral rollback and translation, improving deep flexion clearance.
    • Surgical techniques optimize soft tissue balance and implant positioning for enhanced motion.
    • Outcome studies confirm functional benefits of high-flexion TKA.

    Conclusions:

    • Advancements in component design and surgical techniques have successfully improved high-flexion capabilities in total knee arthroplasty.
    • High-flexion TKA offers significant benefits for patients requiring deep knee bending.
    • Further research and clinical application of these designs are supported by positive outcomes.
