Area of Science:

  • Medical Education
  • Anatomical Modeling
  • Surgical Simulation

Background:

  • Knee aspiration and intra-articular injections are essential procedures for medical trainees.
  • Developing realistic and cost-effective simulation models is crucial for procedural training.

Purpose of the Study:

  • To create a knee model for practicing knee aspiration and intra-articular injections.
  • To evaluate the efficacy and acceptability of this novel teaching model.

Main Methods:

  • A knee model was constructed using plastic, rubber, and silicone, replicating anatomical structures including the femur, tibia, patella, and synovial space.
  • The model was filled with water to simulate joint aspiration, and its realism was assessed by medical students, residents, and orthopedic staff.

Main Results:

  • The model was rated as good to very good by 80-90% of users, indicating high satisfaction.
  • Feedback suggested modifications for different sizes and improved ballotment testing for enhanced realism.
  • There was a consensus on the need for mass production of the model.

Conclusions:

  • The developed knee model is an acceptable and affordable tool for simulating arthrocentesis.
  • The model offers a valuable adjunct for training medical professionals in knee joint procedures.
