INTRODUCTION This technical note describes a new arthroscopic technique to repair the peripheral attachment lesion of the posterior horn of the medial meniscus. The operation was performed under arthroscopy using a standard anterior portal. SURGICAL TECHNIQUE A FasT-Fix needle was inserted obliquely close to the tibial plateau and the first implant was inserted into the joint capsule dependin...

There have been several techniques to repair the medial meniscus posterior root tears (MMPRTs) with the goal of restoring the anatomic and firm fixation of the meniscal root to bone. Many anatomic studies about the menisci also have been developed, so a better understanding of the anatomy could help surgeons perform correct fixation of the MMPRTs. The meniscal roots have ligament-like structure...

Many meniscal root tears remain unrepaired, potentially due to under-recognition and the technical challenge of repairing them. A great effort is made to preserve the native meniscus and restore the circumferential fibers for hoop stress resistance. It has been well demonstrated in the literature that failure to repair this will lead to increased contact pressures in the medial compartment and ...

The meniscus was once considered a functionless remnant of muscle that should be removed in its entirety at any sign of abnormality. Its role in load distribution, knee stability, and arthritis prevention has since been well established. The medial and lateral menisci are now considered vital structures in the healthy knee. Advancements in surgical techniques and biologic augmentation methods h...

Native joint preservation has gained importance in recent years. This is mostly to find solutions for limitations of arthroplasty. In the knee joint, the menisci perform critical functions, adding stability during range of motion and efficiently transferring load across the tibiofemoral articulation while protecting the cartilage. The menisci are the most common injury seen by orthopedicians, e...

BACKGROUND Meniscus damage can be caused by trauma or degeneration and is therefore common among patients of all ages. Repair or regeneration of the menisci could be of great importance not only for pain relief or regaining function but also to prevent degenerative disease and osteoarthritis. Current treatment does not offer consistent long-term improvement. Although preclinical research focusi...

The first meniscal repair was described by Annandale in 1885. In addition to the patients’ reported 1-month stay in the hospital, many other changes have occurred in the techniques of meniscal repair since that time. Most repairs are performed rthroscopically, with a variety of suture techniques ranging from inside-out, outsiden, to all-inside. Regardless of the technique utilized, vertical sut...

There is a greater incidence of discoid meniscus in Asian countries than in Western countries, and bilateral discoid menisci are also common. The discoid meniscus may be a congenital anomaly, and genetics or family history may play a role in the development of discoid menisci. Because the histology of discoid meniscus is different from that of normal meniscus, it is prone to tearing. Individual...

The optimal treatment for combined osteochondritis dissecans (OCD) with considerable bony defect of the lateral femoral condyle (LFC) and torn discoid lateral meniscus is unclear. We present a case of a 15-year-old female who was a gymnast and had a large OCD lesion in the LFC combined with deficiency of the lateral meniscus. The patient underwent the "one-step" technique of osteoperiosteal aut...

BACKGROUND Most biomechanical studies for evaluation of the structural properties of meniscal repairs have been performed in tensile loading scenarios perpendicular to the circumferential meniscal fibers. However, meniscal repair constructs are also exposed to shear forces parallel to the circumferential meniscal fibers during healing, particularly in the midportion of the meniscus. HYPOTHESI...
