[Translated article] Tibial slope in ACL reconstruction: When should it be corrected?

Area of Science:

• Orthopedic surgery
• Biomechanics
• Sports medicine

Background:

• The tibial slope is a critical anatomical determinant of knee anteroposterior stability.
• Elevated tibial slope is associated with increased anterior tibial translation and anterior cruciate ligament (ACL) stress.
• This factor is linked to a higher risk of graft failure after ACL reconstruction.

Purpose of the Study:

• To review current evidence on the clinical significance of tibial slope.
• To examine controversies surrounding tibial slope measurement techniques.
• To discuss indications for surgical correction of tibial slope.

Main Methods:

• Systematic literature review.
• Analysis of biomechanical studies.
• Evaluation of clinical outcomes research.

Main Results:

• Tibial slope significantly influences knee joint biomechanics and ACL loading.
• Variability exists in radiographic and intraoperative measurement methods.
• Debate continues regarding optimal surgical thresholds for correction.

Conclusions:

• Tibial slope is a crucial factor in knee stability and ACL integrity.
• Standardized measurement protocols are needed.
• Further research should clarify surgical correction guidelines for improved patient outcomes.
