Knee Joint

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...

Background:

Robotic-arm assistance is increasingly utilized in total knee arthroplasty (TKA) for potential improvements in accuracy and patient outcomes.
Computed tomography (CT)-based robotic systems aid in preoperative planning, intraoperative adjustments, and bone cutting during TKA.

Purpose of the Study:

To describe the second-generation iteration of a CT-based robotic surgical technique for total knee arthroplasty.
To highlight the new features of the upgraded robotic system through a case study.
To provide a step-by-step procedural guide for the enhanced robotic TKA technique.

Main Methods:

Utilized a second-generation CT-based robotic system for total knee arthroplasty.
Employed computed tomography for preoperative planning and intraoperative guidance.
Documented the surgical procedure, focusing on the application of new system features.

Main Results:

The second-generation CT-based robotic system demonstrated its utility in a total knee arthroplasty case.
New features of the upgraded system were successfully integrated into the surgical workflow.
The procedure served as a practical demonstration of the enhanced robotic technique.

Conclusions:

The second-generation CT-based robotic system represents an advancement in robotic-assisted TKA.
This technique offers a detailed approach for surgeons utilizing advanced robotic technology.
Further adoption of such systems may lead to improved TKA results.
