3D printing has transformed various fields, including medical education and the creation of simulators for clinical procedure training. Arthrocentesis is a valuable procedure for all general practitioners. Objective: To develop an affordable knee simulator prototype for arthrocentesis that accurately mimics the anatomical features of the joint cavity and performs the procedure with an acceptable level of realism. Methods: A prototype was built using a high-density foam base and silicone polymers with elastic properties to replicate soft tissue. The patella was 3D printed. Medical residents and specialist instructors evaluated the simulator for anatomical accuracy, tactile feedback, and educational usefulness. Results: More than 60% of participants found the model's realism adequate. Specifically, 57.14% of instructors and 30.77% of residents felt that the resistance of the patella was similar to real bone. The procedure was successfully performed in 100% of the cases evaluated. Conclusion: This study successfully developed an inexpensive knee simulator that replicates anatomical features for educational purposes.
