Arthroscopic all-inside lateral meniscus suture using posterolateral portal.

Area of Science:

• Orthopedic Surgery
• Arthroscopy
• Sports Medicine

Background:

• Lateral meniscus posterior horn peripheral longitudinal tears are common, often associated with anterior cruciate ligament (ACL) injuries or discoid lateral meniscus.
• Conventional arthroscopic meniscus repair techniques (inside-out, outside-in, all-inside) can be technically challenging and cumbersome.

Purpose of the Study:

• To describe a new arthroscopic all-inside suture technique for lateral meniscus posterior horn tears.
• To utilize a single posterolateral portal for improved visualization and simplified repair of these specific meniscus tears.

Main Methods:

• Arthroscopic visualization via anteromedial portal with a transcondylar approach to the posterolateral compartment.
• Introduction of a suture hook through the posterolateral portal to pass suture through the peripheral rim and torn meniscus fragment.
• Retrieval of suture ends via the posterolateral portal for knot tying, facilitating a strong repair.

Main Results:

• The described technique allows thorough visualization of posterolateral structures.
• Achieves excellent coaptation of the torn meniscus with secure knot tightening.
• Effectively avoids inadvertent cartilage injury during the repair process.

Conclusions:

• This single posterolateral portal all-inside suture technique provides a viable and effective method for repairing lateral meniscus posterior horn tears.
• The technique simplifies the procedure, enhances visualization, and ensures a stable repair, potentially improving outcomes for meniscus injuries.
