Individualized indication for slope changing osteotomy in ACL insufficiency: the Avalanche Concept

Area of Science:

• Orthopedic surgery
• Sports medicine
• Biomechanics

Background:

• Management of increased posterior tibial slope (PTS) in anterior cruciate ligament (ACL) injuries is complex and debated.
• Current indications for slope-correcting osteotomies often rely on limited cut-off values, neglecting multifactorial patient risks.
• Existing risk factors for ACL insufficiency are frequently linked to PTS, highlighting a gap in current treatment strategies.

Purpose of the Study:

• To propose a novel framework, The Avalanche Concept, for complex ACL treatment.
• To integrate posterior tibial slope (PTS) assessment into a comprehensive, individualized risk stratification for ACL injuries.
• To enhance decision-making for surgical interventions like slope-correcting osteotomies.

Main Methods:

• Development of The Avalanche Concept, inspired by avalanche risk stratification.
• Comprehensive analysis of individual risk factors and patient circumstances associated with ACL injuries.
• Standardized measurement of posterior tibial slope (PTS) to complement risk factor analysis.

Main Results:

• The Avalanche Concept utilizes a heat map to visually represent the strength of recommendation for slope correction.
• It integrates individual risk profiles with objective PTS measurements.
• This approach offers a more nuanced decision-making tool compared to existing methods.

Conclusions:

• The Avalanche Concept provides a new paradigm for personalized ACL injury management.
• Integrating PTS into a comprehensive risk assessment improves treatment strategy development.
• This individualized approach aims to optimize outcomes for patients with ACL injuries and increased PTS.
