Severe genuvalgo of 35 degrees Case Presentation, Alcívar Hospital.

Abstract

Introduction: Severe genu valgus (deviation >20°) presents a significant orthopedic challenge, associated with ligament instability, muscle atrophy, and severe gait disturbances. Varizing osteotomies are an effective alternative for shifting the load axis to the medial compartment in symptomatic patients, improving joint function. Objective: To demonstrate the functional (using the KSS scale) and radiological results after correcting a severe genu valgus through variating osteotomy of the distal femur. Materials and methods: The case of a 20-year-old male with a history of trauma to the left knee at age 9, resulting in a progressive deformity, was evaluated. The patient had a severe genu valgus of 35° with load, notable quadriceps atrophy, and a 10 cm shortening, which limited his standing and gait. Treatment involved a varying supracondylar osteotomy of the distal femur, fixed with a medial condylar plate.

Results: The clinical and functional scores on the Knee Society Scale (KSS) significantly increased from 40 points (Poor) to 90 points (Excellent) after surgery. Additionally, an excellent postoperative range of motion was achieved.

Conclusion: In young patients with extreme valgus malalignment and functional impairment, varizing supracondylar osteotomy with condylar plate fixation is a well-tolerated and effective surgical option. This procedure restores knee function, allows early ambulation, and substantially enhances the patient's quality of life.
