Alignment and stability are two key factors for success in total knee arthroplasty (TKA). Several techniques have been advocated, the two best known being measured resection and tensioned gaps.

Dogma and fuzzy wording have cast an obscure shadow on the dualistic discussion between proponents of both techniques.

This review is an attempt to clarify definitions, analyse the flaws and pitfalls in the different techniques and make some suggestions for improvement.
