This fact is strongly supported by different studies. Early results of the third-generation procedures seem very promising with at least comparable deformity correction and less postoperative stiffness and pain compared with some open osteotomies. Percutaneous, intra-articular, chevron osteotomy is one of this type of procedures and presents some advantages when comparing with other third-generation surgeries. Percutaneous, intra-articular, chevron osteotomy accurately reproduces the open chevron technique with all its known advantages. Our recommendation is that no surgeon should begin doing percutaneous surgery until they have gone through specific cadaveric training. Level of Evidence: Diagnostic Level IV.
