Accuracy of blocking screw technique

Measurement	n	Mean accuracy (range)
MAD	53	91.6% (25.0–100.0)
LDFA	46	97.0% (62.5–100.0)
MPTA	36	97.0% (50.0–100.0)
PDFA	45	99.6% (83.3–100.0)
PPTA	34	100.0% (100.0–100.0)

LDFA, lateral distal femoral angle; PDFA, posterior distal femoral angle; MPTA, medial proximal tibial angle; PPTA, posterior proximal tibial angle; MAD, mechanical axis deviation
