The intra-articular injection model of the knee joint is an important practical training tool in orthopedic and nursing teaching. By simulating the anatomical structure of the knee joint, it clearly presents the spatial relationship between the patella, femur, tibia and the joint cavity, helping trainees accurately locate the needle insertion point.

The model can truly simulate the puncture resistance and the feel of needle insertion, enabling trainees to systematically master the key points of body position placement, needle insertion Angle, depth control and drug injection. Repeated practice in a risk-free environment can effectively reduce the tension of beginners and the rate of clinical misoperation, and decrease the pain and complications of patients.

At the same time, it helps to strengthen the awareness of aseptic operation, standardize the diagnosis and treatment process, and enhance the confidence in operation and clinical adaptability. This model can also be used for skills assessment and standardized training, promoting teaching consistency and operational standardization, which is of great significance for improving the clinical safety and therapeutic effect of intra-articular injection of the knee joint.
