Optimized Surgical Positioning Using an L-Shaped Support for Arthroscopic Repair of Lateral Meniscus Tears

Area of Science:

• Orthopedic Surgery
• Knee Biomechanics
• Sports Medicine

Background:

• Traumatic lateral meniscal injuries increase osteoarthritis risk.
• Meniscal preservation is key for knee joint function.
• Lateral meniscus requires specific surgical considerations due to its anatomy.

Purpose of the Study:

• To describe a simple surgical positioning technique for improved lateral compartment visualization during arthroscopy.
• To facilitate surgical repair of lateral meniscus tears, especially bucket-handle tears.
• To reduce iatrogenic injury to articular cartilage during lateral meniscus repair.

Main Methods:

• Utilized an L-shaped support, typically for total knee arthroplasty, to aid in lateral compartment distraction.
• Described a technical note on the positioning technique for arthroscopic lateral meniscus repair.
• Discussed biomechanical considerations and repair strategies, including inside-out and outside-in sutures.

Main Results:

• The L-shaped support technique significantly improved exposure of the lateral femorotibial compartment.
• Reduced the need for manual assistance during arthroscopic lateral meniscus surgery.
• Facilitated easier surgical repair, particularly for complex tears.

Conclusions:

• The described positioning technique enhances visualization and access for lateral meniscus repair.
• This method can improve surgical outcomes and contribute to long-term knee joint preservation.
• Optimized repair strategies, combined with improved positioning, are vital for managing lateral meniscus injuries.
