Optimal Sequence of Corrective Surgeries for Concomitant Valgus Knee and Rigid Pes Planus Deformities: The Knee-First...

Area of Science:

• Orthopedic Surgery
• Biomechanics
• Lower Extremity Reconstruction

Background:

• Valgus knee and rigid pes planovalgus deformities often coexist.
• The optimal surgical sequence for correcting these combined deformities remains debated.
• Etiology and disease progression suggest a relationship between these conditions.

Observation:

• A 72-year-old female presented with concurrent valgus knee and rigid pes planovalgus.
• The patient underwent successful treatment involving total knee arthroplasty followed by triple arthrodesis and Achilles lengthening.
• Careful surgical planning is crucial to prevent alignment errors impacting gait.

Findings:

• The authors recommend a specific operative sequence: knee correction first, followed by foot and ankle correction.
• This approach contrasts with limited existing literature on the subject.
• Successful treatment was achieved in the presented case study.

Implications:

• The findings suggest a preferred surgical strategy for patients with combined knee and foot deformities.
• Further prospective research is necessary to validate the optimal operative sequence.
• This evidence can guide surgical planning for improved patient outcomes in complex lower extremity reconstruction.
