Constitutional alignment predicts medial ligament balancing in mechanically aligned total knee arthroplasty for varus knees

ConclusionLigament balancing using MNP was determined by constitutional alignment rather than medial soft tissue contracture. Patients with constitutional varus who had a larger medio-lateral gap difference in extension also had a higher incidence of having had MNP to both anterior and posterior sMCL fibres.Level of evidenceRetrospective comparative study, level IV.
