  • Among the various types of congenital meniscal anomalies, the double-layered lateral meniscus is extremely rare. The double-layered meniscus consists of both the upper additional and the lower normal meniscus. As the upper additional meniscus is mobile, it can be easily displaced, while the lower lateral meniscus is usually normal in shape and volume. A 42-year-old woman suffering from pain and locking of her left knee underwent Magnetic resonance imaging (MRI) examination and an arthroscopic surgery. A rare meniscal abnormality was seen in her left knee, which presented as a double-layered lateral meniscus with displacement. It was remarkable that the upper additional meniscus was displaced over the intercondylar eminence of the tibia and it mimicked a bucket-handle tear. Even though it is rare, it is necessary to consider the possibility of displaced double-layered meniscus in the differential diagnosis of a bucket-handle tear. Here, we report the MRI and arthroscopic findings of a displaced double-layered lateral meniscus, which was similar to the bucket-handle tear.

  • Root tear of the posterior horn of the medial meniscus can occur from trauma or chronic degeneration, leading to meniscus extrusion, articular cartilage loss, osteophyte formation, and medial joint space narrowing. It is common on middle age with or without minor trauma. We experienced a case of medial meniscus posterior horn root tear in 13 years old boy during baseball game. We performed 1 direct suture anchor repair for medial meniscus posterior horn root tear in adolescent and report clinical result.

  • Although the lateral discoid meniscus of the knee has been observed frequently, the discoid medial meniscus has rarely been reported in the literature. A discoid medial meniscus with the horizontal tear and the peripheral tear of upper lip were observed. This tear pattern is not usual in the lateral discoid meniscus as well as in the normal meniscus. A plausible mechanism of the tear pattern compared with the normal shape and the discoid lateral meniscus was discussed in the following.

  • Purpose: We analyzed the location and type of meniscus tear associated with ACL rupture in order to estimate and prepare whether the meniscus tear is in a repairable location. Materials and Methods: We reviewed 78 cases who had ACL reconstructive surgery due to ACL rupture. We set the period of acute injury on the basis of under 12 months after trauma. The location and type of meniscus tear was analyzed in accordance with MRI findings and arthroscopic findings. Results: The 50 cases of meniscus tear were detected out of the 78 ACL rupture;32 cases were lateral meniscus tears, 24 were medial meniscus tears and 6 cases were both menisci tears. From a total of 56 meniscus tears, 30 cases were longitudinal tears, 22 cases were red-red zone tears and 35 cases(62%) were posterior horn tears. Conclusion: The most common type of meniscus tear associated with ACL rupture war longitudinal tear at the red-red zone or meniscosynovial junction. Majority of the tears located at that place can be healed with conservative treatment, arthroscopic meniscus suture.

  • Purpose: To compare the success rates of performing only silicone tube intubation versus carrying out both conjunctival resection and silicone tube intubation. Methods: The subjects of this study involved 62 patients (96 eyes) between October 2015 and May 2017 who were diagnosed as having punctal stricture or nasolacrimal duct stenosis. Out of 96 eyes, 47 underwent only silicone tube intubation, and 49 underwent both silicone tube intubation and conjunctival resection. Three parameters were measured at 1, 3, and 6 months after the surgery: the area of the tear meniscus using RTVue-100 anterior segment optical coherence tomography, the height of the tear meniscus using a slit lamp microscope, and the subjective satisfaction of patients as a result of improved sympotms like epiphora. The surgery was considered successful when the patients' experienced the resolution of symptoms and reduction of the area and height of the tear meniscus. Results: The area of the tear meniscus, height of the tear meniscus, and subjective satisfaction of patients was superior in the group that underwent both silicone tube intubation and conjunctival resection compared silicone tube intubation only. Based on these results, the success rate of the surgery was 68.9% in the group that underwent only silicone tube intubation and 78.7% in the group that underwent both silicone tube intubation and conjunctival resection. Conclusions: The resection of relaxed plica semilunares seems to increase the success rate of silicone tube intubation through the reduction of the area and height of the tear meniscus. Therefore, after determining the degree of conjunctivochalasis, if it was found to be severe, a combination with conjunctival resection was expected to increase the success rate of the surgery.

  • Background and Purpose : MRI(Magnetic Resonance Imaging) has become one of the most sensitive diagnostic tool no evaluate problems of the knee, because it enables us to identify not only osseous tissue but also soft tissues including muscle, fascia, tendon, ligament, meniscus and fat around the knee joint. Objective : To compare between MRI reading and pain, duration, physical examination in patients with pain of knee joint. Methods : 20 patients with pain of knee joint included in this study. This study researched pain-degree, duration, physical examination with pain of knee joint. Using MRI(Horizon Lx 1.0T-GE), we obtained the results. Results : 1. In the distribution of sex; Female rate was 80.0% and male rate was 20.0%. In the distribution of age, above sixty group was the largest group by each 55.0%. 2. In the distribution of MRI reading; 'Meniscus horm tear' was 70.0%, 'Osteoarthritis' was 55.5%, 'ACL partial tear' was 15.0%, 'Bone bruise at tibia, femur' was 15.0%. 3. Correlation between duration of pain and MRI reading showed that acute and subacute stage related various MRI reading, that chronic stage related 'Osteoarthritis' and 'Meniscus horn tear' by each 69.2%, 92.3%. 4. Correlation between pain and MRI reading showed that severe pain(GVI) related 'ACL partial tear, PCL partial tear' by each 100%, that mild pain(GII) related 'Osteoarthritis, Meniscus horn tear' by each 70.0%, 80.0%. 5. Correlation between physical examination and MRI reading showed that Drawer test related ACL partial tear by each 60.0%, that McMurray test related 'Meniscus horn tear' by each 75.0%. 6. Correlation between effect of treatment and MRI reading showed that 'Osteoarthritis, Meniscus horn tear' related good effect, that ACL partial tear related poor effect. Conclusions : These results suggest that acute and sever pain relate 'ACL partial tear, PCL partial tear', that chronic and mild pain related 'Osteoarthritis, Meniscus horn tear'. So it is responsibility to use MRI as a sensitive diagnostic tool in the knee problems.

  • Purpose: To evaluate changes in the tear meniscus area and tear meniscus height over time in patients with dry eye syndrome, using anterior segment spectral-domain optical coherence tomography after the instillation of 3% diquafosol ophthalmic solution. Methods: Sixty eyes from 30 patients with mild to moderate dry eye syndrome were included. Tear meniscus images acquired by anterior segment spectral-domain optical coherence tomography were analyzed using National Institutes of Health's image-analysis software (ImageJ 1.44p). Tear meniscus area and tear meniscus height were measured at baseline, 5 minutes, 10 minutes, and 30 minutes after instillation of a drop of diquafosol in one eye and normal saline in the other eye. Changes in ocular surface disease index score, tear film break-up time, corneal staining score by Oxford schema, and meibomian expressibility were also evaluated at baseline, and after 1 week and 1 month of a diquafosol daily regimen. Results: Sixty eyes from 30 subjects (mean age, 29.3 years; 8 men and 22 women) were included. In eyes receiving diquafosol, tear volume was increased at 5 and 10 minutes compared with baseline. It was also higher than saline instilled eyes at 5, 10, and 30 minutes. Changes in tear volume with respect to baseline were not statistically different after the use of diquafosol for 1 month. Ocular surface disease index score, tear film break-up time, and Oxford cornea stain score were significantly improved after 1 week and 1 month of daily diquafosol instillation, but meibomian expressibility did not change. Conclusions: Topical diquafosol ophthalmic solution effectively increased tear volume for up to 30 minutes, compared to normal saline in patients with dry eye syndrome.

  • The objective of this case report was to evaluate meniscal suturing for a young patient with a chronic radial tear of the incomplete discoid lateral meniscus. The patient underwent saucerization in conjunction with repair of the displaced radial tear of the discoid meniscus. Six-months after surgery, arthroscopic examination showed the repaired meniscus to be healed well with good continuity. Repair of radial tears, even chronic tears, should be considered for young patients with torn discoid lateral menisci.

  • Purpose: To evaluate the thickness of the posterior horn of the medial meniscus accompanying with degenerative radial tear. Materials and Methods: We retrospectively reviewed 170 cases which show degenerative meniscal tear with variable degree of meniscal degeneration from February 2000 to February 2010. All cases were older than 40 years and 57 cases were men and 113 cases were women. Mean age were 55-year-old. We grouped the cases into 3 categories. Group A were composed with cases which showed horizontal and radial tear in posterior horn of medial meniscus. Group B showed horizontal tear only and group C showed intrasubstance degeneration without meniscal tear. Results: The mean thickness of medial meniscus posterior horn in group A, B, C were 7. 44 mm, 6.52 mm, 6.04 mm respectively. Group A showed significant increase of the thickness of medial meniscus posterior horn than group B, C. Group B also showed significant increase of thickness than group C. The degree of meniscal degeneration was highest in group A, which showed significant higher meniscal degeneration than group B and C, and, group B showed higher degeneration than group C, however, there was no statistically difference between group A and B regarding the degree of meniscal degeneration. Conclusion: The thickness of medial meniscus posterior horn was increased when accompanied with radial tear, which may elicit pain caused by meniscal impingement.
