Which of the following lists three common leg misalignments?

• A. Knock Knees: Knees touch but ankles don't; Bow Legs: Ankles touch but knees don't; Hyperextended Knees: Knees extend beyond 90 degrees
• B. Genu Varum; Genu Valgum; Pes Planus
• C. Anterior Pelvic Tilt; Posterior Pelvic Tilt; Pelvic Up Slip
• D. Scoliosis; Kyphosis; Lordosis

Answer: (A)

Common leg alignment patterns you might observe are knock knees, bow legs, and hyperextended knees. Knock knees describe knees that touch or come together while the ankles stay apart, showing a valgus alignment in the knees. Bow legs describe ankles touching while the knees stay apart, reflecting a varus alignment. Hyperextended knees refer to knees that straighten beyond neutral, showing a sagittal-plane deviation. Together these three capture typical leg misalignments that can affect how joints load during standing and movement.

The other options mix in conditions that involve the feet, pelvis, or spine rather than the legs themselves, or pair terms that aren’t leg alignments, so they aren’t the three common leg misalignments being asked for.
