The Principles of Knee Joint Preservation

Area of Science:

• Orthopedics
• Sports Medicine
• Biomechanics

Background:

• Knee joint preservation relies on three interdependent factors: alignment, meniscal status, and ligament stability.
• Deficiencies in one factor negatively impact the others, disrupting knee homeostasis.
• The anterior cruciate ligament (ACL) and medial meniscus are critical for preventing anterior tibial translation.

Purpose of the Study:

• To emphasize the interconnectedness of knee joint preservation factors.
• To highlight the impact of these factors on articular cartilage health.
• To guide surgeons in addressing all relevant factors for successful knee cartilage pathology treatment.

Main Methods:

• Review of biomechanical principles governing knee joint stability.
• Analysis of clinical observations regarding interdependencies between knee structures.
• Synthesis of evidence on outcomes of cartilage preservation procedures.

Main Results:

• Medial meniscal deficiency increases ACL reconstruction failure risk.
• Chronic ACL insufficiency elevates the risk of medial meniscus tears.
• Optimal outcomes for cartilage procedures require correction of malalignment, meniscal deficiency, and ligamentous deficiency.

Conclusions:

• Successful knee joint preservation necessitates a holistic approach.
• Surgeons must evaluate and address alignment, meniscal status, and ligament stability in patients with knee cartilage pathology.
• Comprehensive management of all three factors is essential for favorable surgical results.
