Bone void fillers in opening wedge high tibial osteotomy - is it necessary and safe to use them?
What is it about?
This is a systematic review about the question if it is necessary and safe to use bone void fillers (autograft, allograft or synthetics) in high tibial osteotomy. The rate of bone healing, delayed and non-union was assessed with regards to opening gap size in a large patient cohort.
Why is it important?
High tibial osteotomy (HTO) is used to make a straight leg from bowed legs. This aims for correction of loading within the joint and preventing osteoarthritis progression. When doing opening wedge HTO one creates gaps on the medial side. The bone gap can be left alone or filled with a variety of bone void fillers such as allograft, autograft or synthetics.
