Area of Science:

Orthopedic Surgery
Knee Arthroscopy
Meniscal Repair

Background:

Meniscal radial root tears compromise knee function and stability, particularly in anterior cruciate ligament-deficient knees.
Traditional transtibial pullout techniques for paracentral radial tears can result in nonanatomic and high-tension repairs.

Purpose of the Study:

To present two all-inside surgical techniques for the anatomic repair of medial and lateral meniscal radial root tears.
To provide technical requirements and tips for successful implementation of these novel repair methods.

Main Methods:

All-inside repair using a dedicated meniscal repair device.
All-inside repair utilizing an antegrade suture passer.
Detailed descriptions of portal placement, stitch configuration, and depth settings for each technique.

Main Results:

The proposed all-inside techniques facilitate anatomic reduction and fixation of meniscal root tears.
Specific guidance is provided to minimize risks, such as vascular injury during lateral meniscus repair.
Recommendations include using at least two stitches with specific depth parameters for optimal repair.

Conclusions:

These all-inside techniques represent advancements in the surgical management of meniscal radial root tears.
They offer a potentially more anatomic and less tensioned repair compared to traditional methods.
Successful application requires careful attention to technical details and portal management.
