The epidemiologic characteristics of concomitant meniscal tears that occur at the time of anterior cruciate ligament (ACL) injury have been variably reported. The purpose of this study was to assess the epidemiology of meniscal tears that occur in the ACL-injured knee of a young, athletic population at a single institution. We were unable to find a difference in meniscal tear incidence based on...

Modern meniscal repair incorporates multiple techniques and adjunctive measures. The classic inside-out repair remains the gold standard and is most appropriate for a bucket-handle type tear of the medial or lateral meniscus. The all-inside technique has gained in popularity recently and has outcomes that approach those of the inside-out repair with decreased morbidity but increased cost. The c...

Ultrasound provides a reliable, non-invasive diagnostic modality for the diagnosis of equine meniscal injuries. Meniscal injuries should be suspected in horses with severe hind limb lameness and prominent stifle effusion. Uniaxial degenerative changes seen radiographically should also be considered suspicious for meniscal injury. Authors’ addresses: Veterinary Medical Teaching Hospital (Flynn) ...

You are attending a continuing education seminar and a colleague tells you about a new orthopedic test for evaluating meniscal tears in the knee. The colleague explains that this orthopedic test, called the Thessaly test, is “great” at evaluating meniscal tears and suggests that you begin using it. At this point, you may wonder just how great the Thessaly Test is for diagnosing meniscal tears a...

We present the first reported case of symptomatic medial dislocation of the medial meniscus in a patient who had no previous history of trauma and who had an otherwise normal knee. The treatment of instability of the medial meniscus is controversial and studies have indicated that certain individuals without a firm meniscal bony insertion may be predisposed to meniscal dislocation. In our patie...

BACKGROUND Limited in vivo kinematic information exists on managing meniscal injury during anterior cruciate ligament reconstruction (ACLR). HYPOTHESIS Isolated anatomic ACLR restores knee kinematics, whereas ACLR in the presence of medial meniscal injury is associated with altered long-term knee kinematics. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS From March 2011 to Decem...

OBJECTIVE Meniscal tears are a common knee injury and increased levels of interleukin-1 (IL-1) have been measured in injured and degenerated joints. Studies have shown that IL-1 decreases the shear strength, cell accumulation, and tissue formation in meniscal repair interfaces. While mechanical stress and IL-1 modulate meniscal biosynthesis and degradation, the effects of dynamic loading on men...

OBJECTIVE This study was undertaken to examine whether bone morphogenetic protein 7 (BMP-7) induces ectopic cartilage formation in the rat tendon, and whether transplantation of tendon treated with BMP-7 promotes meniscal regeneration. Additionally, we analyzed the relative contributions of host and donor cells on the healing process after tendon transplantation in a rat model. METHODS BMP-7 ...

BACKGROUND Magnetic resonance imaging (MRI) of the knee is often performed in patients who have knee symptoms of unclear cause. When meniscal tears are found, it is commonly assumed that the symptoms are attributable to them. However, there is a paucity of data regarding the prevalence of meniscal damage in the general population and the association of meniscal tears with knee symptoms and with...
