Background: The applicability of the coronal plane alignment of the knee (CPAK) classification for unicompartmental knee arthroplasty (UKA) is not yet clear. The current study aimed to address the following questions: 1) what is the distribution of the CPAK classification among patients who underwent medial UKA? and 2) what would be the clinical outcomes for patients whose coronal alignment and joint line obliquity have either changed or been maintained postoperatively?
Methods: This retrospective study involved 325 patients treated with fixed-bearing medial UKA between 2017 and 2019 following a kinematic alignment strategy and using cemented resurfacing implants. Long-leg standing radiographs were utilized for all preoperative and postoperative measurements.
