Impact of preoperative and constitutional alignment on soft tissue stiffness in robot-assisted total knee arthroplasty
This study introduced gap-tension regression for assessing soft tissue stiffness in robot-assisted TKA and showed that stiffness is influenced by preoperative and constitutional alignment. Varus alignment was associated with higher medial-to-lateral stiffness, and CPAK subtypes showed distinct stiffness patterns. These findings may help optimize soft tissue balancing and improve outcomes in TKA.
