  • Many types of meniscal anomalies have been reported. The authors encountered one case of anomalous insertion of the anterior horn of the medial meniscus to the anterior horn of the lateral meniscus, which ran up along the course of the transverse ligament. This anomalous band was detected in MRI of the knee as a horizontal tear of anterior horn of the lateral meniscus but found during the operation as a anomalous insertion of the anterior horn of the medial meniscus. We report the case with a review of the literature.

  • Anomalies of the medial meniscus are rare and difficult to diagnose clinically. Among these anomalies, anomalous insertion of the medial meniscus into the anterior cruciate ligament is rare. Most of the reported cases had no relation to clinical symptoms and were found incidentally during arthroscopy. We report a rare case of anomalous insertion of the medial meniscus into the anterior cruciate ligament with a brief review of the literature.

  • The anterior horn of the medial meniscus is attached to the anterior surface of the tibia. The anterior horns of the medial and lateral menisci are connect with the transverse ligament. The posterior horn of the medial meniscus is firmly attached to the posterior aspect of the tibia just anterior to the insertion of the posterior cruciate ligament. The authors incidentally found an anomalous insertion of posterior horn of medial meniscus into the anterior horn area during arthroscopic examination in the symptomatic knee joint, which had been ruptured anterior cruciate ligament, and report with literature review.

  • The lateral meniscus is morphologically more variable than the medial meniscus. An abnormal lateral meniscus also varies with respect to its size, shape and stability, and such variations can occur in any patient of any age. The most common variant is a discoid lateral meniscus. We recently encountered a patient with a discoid lateral meniscus for which the anterior horn of the meniscus was anomalously inserted into the anterior ACL. The patient was forty five years old women who had persistent pain for three to four years without any specific trauma history. She was preoperatively diagnosed as having discoid lateral meniscus by MRI, and was confirmed the presence of the complex tear and anomalous insertion of the anterior horn of the discoid lateral meniscus into the anterior ACL by arthroscopic examination. Arthroscopic subtotal meniscectomy was performed and the symptoms were improved after surgery.

  • We report a case of a girl with a symptomatic anomaly of medial meniscus. The complaint of the patient was pain and snapping of the knee. The anterior horn of medial meniscus has anomalous insertion which was extended to the intercondylar notch of the femur on the surface of the anterior cruciate ligament, it attached to lateral wall of medial femoral condyle. This anomalous band was not detected in MRI of knee but found during the operation. After resection of anomalous band, the symptoms completely disappeared.

  • We investigated the fabrication and characteristics of the nitride-based spin-polarized LEDs with room-temperature ferromagnetic (Ga,Mn)N layer as a spin injection source. The (Ga,Mn)N thin films having room-temperature ferromagnetic ordering were found to exhibit the negative MR and anomalous Hall resistance up to room temperature, revealing the existence of spin-polarized electrons in (Ga,Mn)N films at room temperature. The electrical characteristics in the spin LEDs did not degraded in spite of the insertion of the (Ga,Mn)N layer into the LED structure. In EL spectra of the spin LEDs, it is confirmed that the devices produce intense EL emission at 7 K as well as room temperature. These results are expected to open up new opportunities to realize room-temperature operating semiconductor spintronic devices.

  • The Thomsen-Haskell method was used to determine sensitivities of the Rayleigh-wave phase velocities and spectral amplitude of vertical ground motion to insertion of a single velocity-anomaly layer into overburden underlain by a basement. The reference model comprised a 9-m thick overburden with shear-wave velocity (${\nu}_s$ of 300 m/s above a half-space with ${\nu}_s$ = 1000 m/s. The inserted layer, with a velocity of 150, 225, 375, or 450 m/s and a thickness of 1, 2, or 3 m, was placed at depths increasing from the surface in increments of 1 m. Phase velocities were computed for frequencies of 4 to 30 Hz. For inserted layer models, we placed an anomalous layer with thickness of 1 ~ 3 m, shear-wave velocity of 150 ~ 450 m/s, and at depths of 0 ~ 8 m in the overburden. The frequency range of 8 ~ 20 Hz were the most sensitive to the difference of $C_R$ between the inserted and reference models (${\Delta}C_R$) for h = 1 m and the frequency range got wide as h increased. For all of the models, the spectral amplitudes of the fundamental mode exceeded those of the $1^{st}$-higher mode except at frequencies just above the low-frequency cutoff of the $1^{st}$-higher mode.
