Joint replacement simulation

Definition

Joint replacement simulation refers to the use of computer models and simulations to replicate the process of replacing a damaged joint with an artificial one. This technique enables researchers and medical professionals to study joint mechanics, optimize surgical techniques, and improve prosthetic designs while minimizing risks associated with actual surgeries. These simulations are particularly important for understanding the biomechanical behavior of joints under various conditions, which is essential for enhancing patient outcomes.
