Meniscal suture is a surgical procedure performed to repair tears in the medial meniscus, a cartilaginous structure of the knee that acts as a shock absorber and stabilizer of the joint.
Unlike meniscectomy, which partially or completely removes the damaged tissue, meniscal suture aims to preserve the internal meniscus by repairing it with stitches. Thus, it promotes functional recovery and reduces the risk of developing osteoarthritis in the future. In this opportunity, we will explain what meniscal sutures are and what type of meniscal injury is recommended.
What does meniscal suture consist of?
It consists of the repair with sutures (sewing) of the meniscal tear, without resecting any tissue. It requires a great handling of the arthroscopic technique. As the healing capacity of the meniscus is low and slow, the recovery usually requires more time to resume sports practice, this being around 4 to 6 months.
Meniscal suturing involves direct repair of the meniscus using stitches that stabilize the injury and allow the tissues to heal naturally. This procedure is performed by arthroscopy, a minimally invasive technique that uses a camera and specialized tools to access the joint through small incisions. The choice of the specific technique will depend on the type, size and location of the tear.
Tears located in the peripheral area of the outer meniscus, known as the red zone, are best suited for meniscal suturing, as this area has a good blood supply, which facilitates healing. In contrast, tears in the central or white zone, where blood flow is limited, may not be suitable for this type of meniscal repair.
When are meniscal sutures recommended?
Meniscal suturing is the preferred surgical technique when the tear is repairable and the goal is to preserve as much meniscal tissue as possible within the knee joint. This procedure is usually recommended in young or active patients, especially those who play sports or have a lifestyle that requires joint stability and strength. These suturing techniques are also a great alternative for those who have meniscal injuries associated with an anterior cruciate ligament (ACL) injury, as both problems can be treated simultaneously.
The traumatologist specializing in knee surgery will determine if performing a meniscal suture is feasible after evaluating the type and location of the tear through imaging tests, such as MRI scans, and a physical examination. This will identify whether the injury is located in the posterior part of the internal meniscus or the joint capsule.
Benefits of Meniscal Suture for Meniscal Injury
The main benefit of arthroscopic meniscal suturing is that it preserves the function of the meniscus and meniscal root, which helps maintain knee stability and reduces long-term joint wear and tear. This approach allows patients to regain knee mobility without compromising their future health and to be able to support the leg in the shortest possible time. In addition, as a minimally invasive procedure, meniscal suturing is often associated with less postoperative discomfort and faster recovery than traditional orthopedic and trauma techniques.
Working with suture systems also decreases the risk of developing osteoarthritis compared to total meniscectomy, as the meniscus plays a key role in distributing loads on the joint and protecting the cartilage.
The recovery process after surgery
Recovery time after meniscal suturing requires attention and commitment to an appropriate rehabilitation program. During the first few weeks, the patient will need to limit the load on the affected knee and may require the use of crutches due to flexion stiffness. The physical therapist will design a progressive exercise plan to restore muscle strength and improve joint mobility.
Total recovery time can vary from three to six months, depending on factors such as the type of tear, the technique used, and the patient’s commitment to meniscal body rehabilitation. It is important to follow all medical instructions and avoid activities that may jeopardize the stability of the repair, such as contact sports or sudden movements on the anterior horn or posterior horn of the medial meniscus.
Possible alternatives to meniscal suturing for meniscal injuries
If the tear is not suitable for repair by suturing, other treatment options include partial or total meniscectomy, arthroscopic surgery to remove the damaged portion of the meniscus, or even removal of the meniscus may be considered. In less severe cases, conservative treatments, such as physical therapy, infiltrations or anti-inflammatory medications, may be effective. A knee surgery specialist will evaluate all available options and recommend the most appropriate one for the specific case.
Meniscal Suture Surgery Risks and Complications
Although meniscal suturing is a safe procedure, there are some associated risks, such as infection, joint stiffness or failure of the tear to heal. In some cases, reoperation may be necessary if the repair does not heal properly. These risks are rare and can be minimized by following the specialist’s recommendations and actively participating in the recovery process.
Conclusion
The meniscal suture is an advanced meniscal treatment that repairs damaged cartilage, preserving its function and avoiding long-term complications such as osteoarthritis. This procedure is ideal for active patients seeking a solution that respects the anatomy of their knee and improves their quality of life.
