Research progress on the application of precise osteotomy technology in kinematic alignment total knee arthroplasty
Total knee arthroplasty(TKA)can significantly relieve pain and improve knee joint function,and it has become the recognized"gold standard"for treating end-stage knee osteoarthritis.Traditionally,mechanical alignment(MA)has been considered the"golden"alignment principle during TKA.Despite advancements in prosthesis design and surgical precision,the functional outcomes of MA-TKA have not shown marked improvement.Kinematic alignment(KA)aims to better restore the natural anatomy of the knee joint to promote physiological movement,potentially offering better postoperative patient satisfaction compared to MA.Nevertheless,some studies have pointed out that there is no significant improvement in clinical outcomes with KA-TKA compared to MA-TKA.This lack of improvement may be attributed to the challenge of achieving the precise osteotomy that KA-TKA necessitates.In recent years,the application of new technologies such as patient-specific instrument,computer-assisted navigation system,and orthopedic robot in TKA has significantly enhanced the precision of osteotomies in KA-TKA.However,it remains unclear whether these advancements have led to improved clinical outcomes.This article reviews the research progress on the application of precise osteotomy techniques in KA-TKA.
