LLA Finder
Full-leg alignment, measured in seconds.
LLA Finder analyzes full-length standing leg X-rays. It detects the key landmarks of the hip, knee and ankle on both legs. It then calculates the standard alignment parameters used in deformity assessment and knee-surgery planning.

What it measures
HKA
Hip-knee-ankle angle, with a varus/valgus sign
MAD
Mechanical axis deviation, in millimeters
mLDFA
Mechanical lateral distal femoral angle
mMPTA
Medial proximal tibial angle
mLDTA
Mechanical lateral distal tibial angle
JLCA
Joint line convergence angle
AMA
Anatomical-mechanical angle of the femur
mLPFA
Mechanical lateral proximal femoral angle
CPAK
Classification using aHKA (= mMPTA − mLDFA) and JLO (= mMPTA + mLDFA)
Built for review and control
- Right and left legs analyzed together
- Every landmark is visible on the image and can be dragged to correct it
- Overlays show the mechanical axis and joint lines
- Measurements are scaled to millimeters
- Report-ready output
