Knee Joint

2.8K
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
  • Robotics in Medicine
  • Surgical Technology

Background:

  • Total Knee Arthroplasty (TKA) aims to improve patient outcomes through technological integration.
  • The Active Robot (ARo) system offers automated bone resections for enhanced precision in TKA.
  • Evaluating the learning curve (LC) is crucial for adopting novel surgical tools like the ARo.

Purpose of the Study:

  • To assess the learning curve (LC) associated with the Active Robot (ARo) for Total Knee Arthroplasty (TKA).
  • To determine the number of cases required for surgeons to achieve proficiency with the ARo system.
  • To investigate the impact of the learning curve on surgical efficiency and patient outcomes.

Main Methods:

  • A multi-center prospective study involving 115 patients undergoing ARo-assisted TKA.
  • Surgical time (Operative Time - OT) was divided into surgeon-dependent and surgeon-independent components.
  • Complication rates and patient-reported outcome (PRO) scores were analyzed for learning curve trends.

Main Results:

  • Operative time significantly decreased between early (cases 1-3) and later (cases 10-12) procedures.
  • Surgeon-dependent time analysis indicated individual learning curves ranging from 12 to 19 cases.
  • No significant differences were found in device-related complications or PRO scores across the study period.

Conclusions:

  • The Active Robot (ARo) for TKA demonstrates a short learning curve, typically within 10-20 cases.
  • The learning curve primarily influences the operative time associated with robotic-specific tasks.
  • No adverse effects of the learning curve were observed on device-related complications or patient-reported outcomes.
