Higher Association of Pelvis-Knee-Ankle Angle Compared With Hip-Knee-Ankle Angle With Knee Adduction Moment and Patient-Reported Outcomes After High Tibial Osteotomy

Higher Association of Pelvis-Knee-Ankle Angle Compared With Hip-Knee-Ankle Angle With Knee Adduction Moment and Patient-Reported Outcomes After High Tibial Osteotomy

High tibial osteotomy (HTO) reduces the load distribution of the medial compartment by modifying leg alignment. Knee adduction moment (KAM), a surrogate measure of dynamic loading in the knee joint decreases after HTO. However, leg alignment does not fully account for KAM. The study examines the association between a new radiographic parameter, the pelvis-knee-ankle angle (PKA), and knee adduction moment (KAM) and patient-reported outcomes after high tibial osteotomy (HTO). The study found that PKA was moderately correlated with KAM peaks before and after HTO and was still associated with KAM peaks after HTO. In contrast, hip-knee-ankle angle (HKA) was weakly correlated with KAM peaks before HTO but not after. PKA was also correlated with the satisfaction subscale of the Knee Society Score (KSS) after HTO. The study suggests that although HKA was not associated with KAM peaks after HTO, PKA was significantly correlated with KAM peaks in patients with varus knee osteoarthritis after HTO.
