Distal Femoral Derotational Osteotomy for Excessive Femoral Anteversion

Area of Science:

• Orthopedic surgery
• Biomechanics
• Medical imaging

Background:

• Excessive femoral anteversion (FA) is linked to patellar maltracking and instability.
• Accurate diagnosis requires imaging like computed tomography (CT) scans.
• Surgical correction can restore normal knee function.

Purpose of the Study:

• To describe a surgical technique for correcting excessive femoral anteversion.
• To evaluate the efficacy of distal derotational femoral osteotomy.
• To highlight the benefits of supracondylar plate fixation.

Main Methods:

• Hip examination and CT scan for diagnosis and quantification of FA.
• Distal derotational femoral osteotomy using a digital inclinometer.
• Plate fixation in the supracondylar location with standard instrumentation.

Main Results:

• The described technique allows for precise correction of femoral anteversion.
• Supracondylar plate fixation offers advantages in reducing surgical morbidity.
• Improved patellar tracking is anticipated post-correction.

Conclusions:

• Distal derotational femoral osteotomy is an effective method for correcting excessive FA.
• This technique, combined with plate fixation, offers a viable solution for improving patellar stability.
• Accurate surgical correction of FA can alleviate associated knee problems.
