    Unicompartmental knee osteoarthritis (UC-KOA) primarily affects the medial compartment and is linked to lower limb malalignment and previous joint injuries.

  • 2

    Surgical strategies for UC-KOA include realignment osteotomies and unicompartmental knee arthroplasty (UKA), both improving function and reducing pain.

  • 3

    Epidemiological data indicate that a significant majority of knee osteoarthritis cases are unicompartmental, supporting compartment-specific surgical approaches.

  • 4

    The review proposes a decision-making algorithm integrating deformity analysis and surgical planning to optimize outcomes for varus UC-KOA patients.

  • 5

    Accurate biomechanical assessment is crucial for surgical planning in varus UC-KOA, focusing on mechanical axes and joint-orientation angles.
