Objectives
Narrative objectives1
Bi-surface type prosthesis have been used in total knee arthroplasty at our institution. Tibial internal rotation during deep flexion was observed in Bi-surface type prosthesis at fluoroscopic analyses. In conventional inserts (dish-type), medial liftoff occurs because posterior subluxation of the lateral femoral condyle dose not occur. Other reports have revealed that eccentric loading of the tibial insert occurs in the liftoff position. Therefore, new inserts modify to medial dish and lateral flat form. But, clinical results of the new inerts have not been showed. This study aims to clarity differences between the conventional and new tibial inserts in the knee stability, the soft tissue balance, the range of motion, and clinical evaluation.
