Technique for Medial Meniscus Ramp Repair: An Anatomic Approach

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Knee Anatomy

Background:

• Medial meniscus ramp lesions frequently accompany anterior cruciate ligament (ACL) injuries.
• These lesions can cause a positive pivot shift and lead to rotational instability if not addressed surgically.
• Current repair techniques often involve suturing the capsule to the meniscus, potentially overlooking key anatomical structures.

Purpose of the Study:

• To propose and describe an anatomical repair technique for medial meniscus ramp lesions.
• To emphasize the importance of refixating the meniscal capsular ligament (MCL) and meniscotibial ligament (MTL) to the bone.

Main Methods:

• The study focuses on a specific surgical technique for repairing ramp lesions.
• This technique involves reattaching the posteromedial capsule and MTL directly to the bone.
• It contrasts with prevailing methods that suture the capsule to the meniscus.

Main Results:

• The proposed technique aims for a sounder anatomical repair by addressing the root of the peel-off injury.
• By refixating the MCL and MTL to their native bone attachment sites, it restores the intended knee biomechanics.
• This approach corrects the meniscocapsular separation more effectively than capsule-to-meniscus suturing.

Conclusions:

• Medial meniscus ramp lesions are best understood as peel-off injuries of the posteromedial capsule, not purely meniscal tears.
• Anatomical repair involves reattaching the capsule and associated ligaments (MCL, MTL) to the bone.
• This refixation technique offers a superior method for restoring stability and function after ACL injury.
