Transosseous Posterior Meniscal Root Reinsertion Using Knotless Anchor for Tibial Fixation

Area of Science:

• Orthopedic Surgery
• Arthroscopy
• Knee Joint Anatomy

Background:

• Posterior meniscal root tears can lead to significant knee joint dysfunction.
• Current reinsertion techniques may have limitations in achieving robust fixation.
• Accurate anatomical reattachment is crucial for restoring knee biomechanics.

Purpose of the Study:

• To present a new arthroscopic technique for posterior meniscal root reinsertion.
• To describe the procedural steps and instrumentation involved.
• To provide a reproducible method for surgeons.

Main Methods:

• Arthroscopic visualization through a central transtendinous portal.
• Creation of a 5-mm transtibial tunnel using an anterior cruciate ligament guide.
• Utilizing a suture device with an eyelet for passing suture through the meniscus.
• Securing the meniscus with a grasper and employing a finger-tip pincer for thread retrieval.
• Performing two stitches and creating a lasso loop for fixation.
• Knotless suture anchor fixation in the anterior tibial cortex.

Main Results:

• The described technique allows for arthroscopic visualization and precise placement of sutures.
• The use of a specialized suture device facilitates meniscal piercing and suture retrieval.
• A knotless suture anchor provides secure fixation of the reinserted meniscal root.

Conclusions:

• This technique offers a viable arthroscopic solution for posterior meniscal root reinsertion.
• The described method ensures secure fixation and anatomical restoration.
• Further studies may evaluate the long-term outcomes and clinical efficacy.
