Long-term Outcomes of Surgically Treated Congenital Dislocation of the Knee.

Background: Congenital dislocation of the knee (CDK) may be idiopathic or associated with another condition, such as Larsen syndrome or arthrogryposis. Surgical reduction of type-3 dislocation may require quadricepsplasty (QP) or femoral diaphyseal shortening (FS). Because it is unknown which treatment is more effective, we evaluated long-term outcomes using patient-reported questionnaires and gait analysis, comparing results by surgery type and underlying diagnosis.

Interference screw versus suture button fixation for tibialis anterior tendon transfer: a biomechanical analysis.

Tibialis anterior tendon (TAT) transfer to the lateral cuneiform is commonly utilized to treat dynamic supination for relapsed clubfoot deformity. Traditional suture button fixation (SBF) may lead to skin necrosis at the button/skin interface. While interference screw fixation (ISF) would mitigate this concern, this fixation method has not been investigated in clubfoot patients.

The Ponseti Method for the Treatment of Clubfeet Associated With Down Syndrome: A Single-institution 18-year Experience.

Background: Although the Ponseti method has been used with great success in a variety of nonidiopathic clubfoot deformities, the efficacy of this treatment in clubfeet associated with Down syndrome remains unreported. The purpose of this study is, therefore, to compare treatment characteristics and outcomes of clubfoot patients with Down syndrome to those with idiopathic clubfoot treated with the Ponseti method.

Methods: An Institutional Review Board-approved, retrospective review of prospectively gathered data were performed at a single pediatric hospital over an 18-year period.

Lateral Cuneiform Ossification and Tibialis Anterior Tendon Width in Children Ages 3 to 6: Implications for Interference Screw Fixation of Tibialis Anterior Tendon Transfers in Children.

Background: While the transfer of the tibialis anterior tendon (TAT) to the lateral cuneiform (LC) following serial casting has been used for nearly 60 years to treat relapsed clubfoot deformity, modern methods of tendon fixation remain largely unstudied. Interference screw fixation represents an alternative strategy that obviates concerns of plantar foot skin pressure-induced necrosis and proper tendon tensioning associated with button suspensory fixation. A better understanding of LC morphology in young children is a necessary first step in assessing the viability of this fixation technique.

The Ponseti Method for the Treatment of Clubfeet Associated With Amniotic Band Syndrome: A Single Institution 20-Year Experience.

Background: Amniotic band syndrome (ABS) is a congenital disorder resulting in fibrous bands that can cause limb anomalies, amputations, and deformities. Clubfoot has been reported in up to 50% of patients with ABS. The purpose of this study is to compare treatment characteristics and outcomes of clubfoot patients with ABS to those with idiopathic clubfoot treated with the Ponseti method.
