Objective: To review the recent progress in the application of three-dimensional digital technology in knee arthroplasty.
Methods: The relevant literature at home and abroad about the three-dimensional digital technology in the applications of knee arthroplasty in recent years was extensively reviewed.
Results: The three-dimensional digital technology can obtain arthroplasty knee morphology and biomechanics, and can estimate preoperative planning osteotomy and the sizes of prostheses, so it can guide knee arthroplasty precisely.
Conclusions: Three-dimensional digital technology can reduce the operation error, improve the operation precision, and improve the effectiveness in knee arthroplasty.
