Evaluation and Management of Meniscal Tears

Area of Science:

• Orthopedic surgery
• Sports medicine
• Biomedical engineering

Background:

• Meniscal tears are common knee injuries.
• Meniscal resection increases joint contact stress and accelerates osteoarthritis.
• Meniscal repair and nonoperative management offer better long-term outcomes than resection.

Purpose of the Study:

• To emphasize meniscal preservation as the primary management principle for meniscal tears.
• To guide individualized treatment decisions for meniscal tears.
• To review current meniscal repair techniques and adjunct therapies.

Main Methods:

• Review of biomechanical evidence and clinical outcomes.
• Analysis of factors influencing treatment decisions (tear morphology, tissue quality, patient factors).
• Evaluation of different meniscal repair techniques (all-inside, inside-out, outside-in) based on tear characteristics.
• Assessment of adjunct treatment strategies like biologic augmentation.

Main Results:

• Meniscal preservation improves long-term joint health compared to resection.
• Treatment decisions must be tailored to individual patient and tear characteristics.
• Repair technique selection depends on tear location and pattern.
• Biologic augmentation shows inconsistent outcomes for enhancing meniscal healing.

Conclusions:

• Meniscal preservation is the cornerstone of managing meniscal tears.
• Individualized, tear-specific treatment strategies are essential for optimal outcomes.
• While repair techniques vary, adjunct therapies like biologic augmentation require further investigation due to inconsistent results.
