Recently, meniscal allograft transplantation has been regarded as a successful procedure in terms of pain relief and functional improvement for the symptomatic patients previously underwent subtotal or total meniscectomy. However, the likelihood of a successful outcome would be reduced by various complications including graft tear, shrinkage, extrusion, infection, progressive chondral injury, and granuloma due to nonabsorbable suture material. Therefore, knee surgeons need to be all aware of the complications and to make an effort to minimize them. The purpose of this article is to review the current literatures regarding clinical results and complications after meniscus allograft transplantation.

Purpose : To introduce arthroscopic partial meniscectomy fur bucket handle tear of medial meniscus using posteromedial portal, which is superior to arthroscopic partial meniscectomy using standard anterior portals commonly used. Method : After arthroscopic examination of the knee, we reduce the torn meniscus, advance the arthroscope into posteromedial compartment under arthroscopic visualization, we make posteromedial portal with reexamination of the compartment and perform arthroscopic partial meniscectomy. Conclusion : With the technique of arthroscopic partial meniscectomy using standard anterior portals, accurate partial meniscectomy can not be done because of inadequate visual field, associated meniscal injuries of posterior horn and cartilage lesion of posterior aspect of the medial femoral condyle can be missed, commonly posterior cruciate ligament can be injured and artificial damage to weight bearing surface of medial femoral condyle is possible. An arthroscopic partial meniscectomy using posteromedial portal is an excellent method fur bucket handle tear of medial meniscus.

Purpose: This study intends to verify the usefulness of magnetic resonance imaging (MRI) for estimate recovery after arthroscopic pull-out repair at root tears of medial meniscus. Materials and Methods: We performed 17 patients who examined MRI and arthroscopy among patients who had received repair of medial meniscus from November, 2007 to June, 2011. To determine restoration meniscus, we performed arthroscopy and MRI. Results: Lysholm knee scores before and after operation were average 56.4 and 79.0 and visual analogue scale (VAS) score was improved from 8 points to 3 points. From secondary look arthroscopy performed after operation, 17 cases showed stabilization after regeneration. However, In MRI, cleft sign implying root tears of medial meniscus was observed in all cases before and after operation, ghost sign was observed in 10 cases and 9 cases respectively, radial linear defect was showed 17 cases and 15 cases respectively. Conclusion: It was not useful that MRI after medial meniscus repair in non-anatomical site, to consider restoration of medial meniscus. To evaluate for recovery medial meniscus after repair more exactly, secondary arthroscopy would be required.

Meniscal allograft transplantation is considered to restore important functions of the meniscus after total and subtotal meniscectomy. There are patients who need meniscal allograft transplantation have concomitant lesions; chronic anterior cruciate ligament tear, chondral defect, and malalignment of the knee. Therefore proper selection of the patients and thorough preparation of operative procedure are imperative to get satisfactory results.

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.

Flap tear is a type of displaced meniscal fragments that is often clinically significant lesions requiring surgical intervention. If the displaced tear is located inferomedial to the tibial plateau and incarcerated into the articular capsule, it can be overlooked from preoperative magnetic resonance imaging evaluation and escape detection during arthroscopic examination. In addition, the clinical feature and treatment result of incarcerated flap tear has not been reported. We present 2 cases of medial meniscus flap tear incarcerated into the articular capsule that showed specific clinical features, in order to emphasize the importance of clinical suspicion of such a lesion for accurate preoperative diagnosis.

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.

Purpose: The purpose of this study was to evaluate the results of treatment for longitudinal meniscal tear in ACL rupture patients by clinical evaluation and $2^{nd}$ look arthroscopy. Materials and Methods: Among the patients who underwent surgery due to ACL rupture and longitudinal meniscal tear between 2002~2009, 32 patients were selected for the study. The patients were devided into three groups; group 1 had repair, group 2 had partial menisectomy due to impossible to repair, group 3 had conservative treatment due to stable meniscus. Comparative retrospective analysis was applied with KT 1000 arthrometer, Lysolm' score, Tegner activity score, IKDC subjective score, and $2^{nd}$ look arthroscopy. Results: Lysolm' score, Tegner activity score, IKDC subjective score showed no statistical difference in all three groups. KT-1000 side to side difference improved from 6.2, 6.15, 6.38 before surgery to 2.56, 2.49, 2.58 after surgery in group 1, 2, and 3, respectively. In group 1, second-look arthroscopy revealed complete healing in 12 patients, incomplete healing without any clinical symptoms in 2, and healing failure in 1. In group 2, second-look arthroscopy showed partial regeneration on margin of meniscectomy. In group 3, second-look arthroscopy revealed complete healing in 2 patients, while 4 showed incomplete healing so that have repaired. Conclusion: In the study, the outcome was better when the stable longitudinal meniscal tear on posterior horn with ACL rupture had active treatment.

Purpose : The purpose of this paper is to analyze the clinical results after meniscal repair using meniscal arrow. Materials and Methods : Between May 1997 and Aug 1998, we repaired 22 tom menisci in 22 patients using meniscal arrows. There were nineteen males and three females with an average age of 27 years. There were longitudinal tear in 14 cases, Bucket-handle tear were 7 cases and horizontal tear was in 1 case. In 22 meniscus tears, 16 cases were associated with anterior cruciate ligament tear. Average number of meniscal arrow that was used were 2.5(ranged 1 to 4). Average follow-up period was 14.7 months(ranged 6 to 22 months). We evaluated the clinical results by the Tapper and Hoover's grading system. Results : There were excellent in 16 cases, good in 4 cases and fair in 2 cases on the clinical results. At the last follow up, the range of the motion of the knee joint were average 135 degrees(ranged 125 to 140 degrees). Mean time elapsed for meniscal repair were 25 minutes(ranged 15 to 40 minutes). Conclusion : Meniscal arrow has many advantages such as short operative time, easy fixation technique, and less neurovascular injury. We think that arthroscopic meniscal repair using meniscal arrow is effective treatment method in selected patient who have longitudinal, bucket-handle tear at the posterior hom associated with anterior cruciate ligament tear.
