Principles of triangulation for arthroscopic surgery

Area of Science:

• Orthopedic Surgery
• Arthroscopy
• Knee Surgery

Background:

• Meniscal tears are common knee injuries.
• Arthroscopic surgery is a standard treatment for meniscal lesions.
• Effective surgical techniques are crucial for successful outcomes.

Purpose of the Study:

• To outline the fundamental principles of arthroscopic meniscal surgery.
• To describe the necessary steps and techniques for meniscal resection.
• To highlight the importance of portal selection and instrumentation.

Main Methods:

• Detailed identification of meniscal lesion type, extent, and location.
• Conceptualization of resection steps.
• Selection of standard and accessory portals.
• Utilizing a combination of mechanical and powered instruments.
• Application of triangulation techniques.

Main Results:

• The standard two-puncture technique may require accessory portals.
• A mix of large and small instruments, often powered, is beneficial.
• Triangulation is effective for most treatable meniscal lesions.

Conclusions:

• Successful arthroscopic meniscal surgery depends on precise lesion assessment.
• Strategic portal and instrument selection are vital.
• Triangulation techniques provide adequate visualization and access for the majority of meniscal repairs.
