- △MPTA the change of MPTA after each surgery (△MPTA = post-operative MPTA−pre-operative MPTA), opening distance the distance between the intersections of the osteotomy lines with the medial cortex during gap opening, opening distance per △MPTA = opening distance × 180÷(△MPTA × π), opening angle the angle formed between two osteotomy lines after osteotomy gap opening, opening angle per △MPTA = opening angle ÷ △MPTA
