摘要：

Kinematic-alignment total knee arthroplasty (KA-TKA) aims to restore natural limb alignment and joint line obliquity, thereby improving patient satisfaction. Restricted KA-TKA (rKA-TKA) addresses abnormal knee anatomies and seeks to replicate natural anatomical structures within safe alignment boundaries. This study introduces a novel device and technique that enables rKA-TKA without computer-assisted surgery (CAS). The new device allows for precise cartilage thickness measurement and adjustment of osteotomy angles, facilitating accurate alignment. A heel-lift technique for tibial osteotomy is presented, offering a reproducible method for determining the osteotomy volume and angle. These innovations make KA and rKA-TKA feasible in any surgical setting, avoiding the high costs and limited availability associated with CAS.
