Knee Joint

3.6K
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...

Area of Science:

  • Orthopedic Surgery
  • Surgical Technology
  • Biomedical Engineering

Background:

  • Total knee arthroplasty (TKA) outcomes are influenced by surgical technique and component placement accuracy.
  • Traditional mechanical instrumentation in TKA can have limitations and inaccuracies.
  • Advancements in surgical navigation aim to improve precision and reproducibility in TKA.

Purpose of the Study:

  • To evaluate the accuracy of disposable navigation systems in TKA compared to standard mechanical guides.
  • To assess the impact of computer navigation on component alignment and position in TKA.
  • To determine if disposable navigation reduces outliers in component placement.

Main Methods:

  • Comparison of component placement accuracy between disposable navigation and traditional mechanical guides.
  • Analysis of outlier incidence in component positioning.
  • Evaluation of surgical variables controlled by computer navigation and intraoperative guides.

Main Results:

  • Disposable navigation significantly increases the accuracy of component placement in TKA.
  • The incidence of outliers is decreased when using disposable navigation compared to standard mechanical guides.
  • Disposable navigation achieves these improvements without necessitating a large computer console in the operating room.

Conclusions:

  • Disposable navigation represents an advancement in TKA, offering enhanced accuracy and reduced outliers.
  • This technology provides a more precise method for component placement, potentially improving implant survival.
  • The use of disposable navigation streamlines the surgical workflow by eliminating the need for bulky equipment.
