[Research progress of difference between high-flexion prosthesis and conventional prosthesis in total knee arthroplasty].

Objective: To summarize the research progress of the difference between high-flexion prosthesis and conventional prosthesis in total knee arthroplasty, so as to offer a reference for clinical choice of prosthesis.

Methods: The relevant literature on high-flexion prosthesis and conventional prosthesis in recent years was extensively reviewed and analyzed.

Results: There are some controversies in range of motion and complications between high-flexion prosthesis and conventional prosthesis; while no obvious difference is found in knee function and satisfaction.

Conclusion: Comprehensive evaluation should be considered when high-flexion prosthesis is selected; and the effectiveness needs further follow-up.
