No= Number, yr = year, Pre = pre-operative, post = post-operative, mLDFA = mechanical lateral distal femoral angle, (°) = degrees, MAD = mechanical axis deviation, mm = millimeter, P. Nerve Decomp. = peroneal nerve decompression, L = left, R = right, f = female, m = male, MPS = mucopolysaccaridosis.

^aThe patient was non-ambulatory, mechanical axis deviation in terms of zones was not calculated.
