Interlocking Open-Wedge Distal Tibial Tuberosity Osteotomy: Stabilizing Technique in the Retro-Tubercle Without...

Area of Science:

• Orthopedic Surgery
• Biomechanics
• Surgical Innovation

Background:

• Knee osteotomy procedures are crucial for treating knee deformities.
• Traditional methods may face challenges with stability and healing.
• The need for supplementary hardware can increase surgical complexity and risks.

Purpose of the Study:

• To introduce and describe the interlocking open-wedge distal tibial tuberosity osteotomy.
• To highlight the unique interlocking mechanism for enhanced stability.
• To demonstrate the potential to eliminate the need for additional fixation hardware.

Main Methods:

• Presentation of a novel surgical technique: interlocking open-wedge distal tibial tuberosity osteotomy.
• Description of the interlocking mechanism resembling a mortise-and-tenon joint.
• Explanation of how the retro-tubercle segments fit together during osteotomy.

Main Results:

• The interlocking mechanism provides a stable retro-tubercle configuration.
• Effectively prevents widening of the retro-tubercle gap and increased posterior tibial slope.
• Eliminates the need for complementary hardware, such as anteroposterior screw fixation.

Conclusions:

• The interlocking open-wedge distal tibial tuberosity osteotomy offers a stable and simplified surgical approach.
• This technique promotes healing and reduces potential complications associated with fixation hardware.
• It represents a significant advancement in knee osteotomy procedures.
