Clinical Comparative Study of Personalized Shoulder, Knee and Ankle Brace

This study is based on human anatomical data and uses computer-aided engineering (CAE) software such as biomedical image processing software, reverse engineering software, CAD software, and finite element analysis software to create a three-dimensional bracing model. With the help of 3D printing technology, we have developed personalized brace, completed the personalized rapid design and optimization of the three series of support equipment products such as the posterior cruciate ligament brace, ankle ankle brace, and shoulder brace.

The traditional brace mainly includes small splints or gypsums. The manufacturing process is rough, and the flexibility is poor. In recent years, with the development of orthopedic surgery, rehabilitation concept, modern polymer materials, and biomechanics, great progress has been made in R&D, production, and assembly of orthoses. In developed countries, orthoses is not only widely used after orthopedic surgery and the department of rehabilitation, but it has become the main auxiliary device for sports trauma surgery, immobilization, treatment, and rehabilitation training. Leading bracing company such as DJO has developed multi-brand correction devices such as Aircast®, Chattanooga, CMF, COMPEX®, DonJoy®, Empi® and ProCare®. However, these braces are not designed and manufactured based on patients. Individually designed products for anatomical structures still have many problems in clinical applications.

Inclusion Criteria: patients accepting arthroscopic surgery of the shoulder, posterior cruciate ligament reconstruction surgery, Achilles tendon rupture repair surgery. Exclusion Criteria: Severe peripheral ligament injury of should, knee and ankle.
