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: The purpose of this study was to correlate the degree of sonographic medial meniscal extrusion with MRI and arthroscopic findings. Materials and Methods: Out of these 32 patients, with medial meniscal tear who went on arthroscopic surgery, 14 patients had the medial meniscal tear and 18 patients had both lateral and medial meniscal tear. The extent of meniscal extrusion without meniscal tear was assesed in 24 patients who did not show meniscal tear on MRI. The extent of meniscal extrusion was measured between tibial medial joint line (excluded osteophyte) and the outer margin of the medial meniscus. Kellgren-Lawrence grading scale was assessed in plain X-ray image and the location of lesion was assessed during arthroscopic surgery. We also measured the extent of meniscal extrusion on MRI and sonography respectively, and compared each other. Results: There was significant difference between patients with medial meniscal tear and both lateral and medial meniscal tear, patients with medial meniscal tear, patients with both medial and lateral meniscal tear, patients without meniscal tear (P value<0.05). Conclusion: The Meniscus tear must be considered when sonography shows the meniscal extrusion more than 5 mm in length.

Meniscal cyst is an uncommon disease of knee joints, arising less frequently from medial meniscus than lateral. Most of they are accompanied with horizontal tear of meniscus. This is the case of 24 year old man who had 2 separate medial meniscal cysts with longitudinal tear on posterolateral side of medial meniscus without trauma. Treatment consisted of arthroscopic decompression of cysts and meniscal repair.

Meniscal allograft transplantation (MAT) is an accepted treatment for the symptomatic postmeniscectomized knee in younger patients. However, the likelihood of a successful outcome is reduced by various complications. One of the complications after MAT is manifested as grafted meniscal tear. However, a bucket handle meniscal tear (BHMT) following MAT is an uncommon complication and furthermore a BHMT after revisional MAT (RMAT) is a extremely rare complication. We encountered a case of BHMT after RMAT in a lateral meniscus. Retrospectively reviewing the case, we could assume the cause, which would be helpful to prevent the complication in further MAT procedures.

Posterior root tear of the medial meniscus are well known. Although very rare, there are reports of anterior root tears of the medial meniscus but no reports on traumatic bony avulsion of the anterior medial meniscus root. This paper reports a case of an isolated bony avulsion of the anterior medial meniscus root, which was successfully repaired arthroscopically.

Purpose: The purpose of this study was to compare the preoperative magnetic resonance image (MRI) findings with postoperative arthroscopic findings on meniscus injury with anterior cruciate ligament (ACL) rupture. Materials and Methods: We reviewed MRI images and arthroscopic findings of 225 patients treated by ACL reconstruction due to rupture, from February 2001 to November 2010. There were 154 cases of meniscus tear in arthroscopic findings. We examined the sensitivity for detecting meniscal tears varied with the presence of a rupture of the ACL, with the location of the tear within the meniscus, and among configurations of meniscal tears. Results: In the presence of a rupture of the ACL, the sensitivity of MRI was 0.88 for medial meniscal tears and 0.69 for lateral meniscal tears. And sensitivity of MRI was lowest in posterior horn and peripheral portion tears in lateral meniscus injury accompanying ACL rupture, sensitivity was low in anterior horn and flap shape tears in medial meniscus injury accompanying ACL rupture. Conclusion: In Meniscus injury with ACL rupture, a special attention shoulder given to the posterior horn and peripheral portion injury in lateral meniscus during arthroscopic surgery due to difficulty in detecting on MRI.

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.

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.

Purpose: This study examined clinical cure and patients' satisfaction degrees by factors influencing surgical operation results, after arthroscopic inside to out repair as a nonabsorbable suture material, in case of meniscal rupture. Materials and Methods: Materials were 110 cases of 95 patients who could make paces for over 12 months from August 1999 to June 2002. Results were evaluated by clinical cure and subjective satisfaction degrees. This study, concerning those results, analyzed age, term from taking pictures to taking surgical operation, rupture section, rupture length, rupture types, lesion of articular-cartilage, and effects of anterior cruciate ligament operation accompanied. Results: 84 cases(76%) were clinically cured, 98 cases(89%) were subjectively satisfied. In case of accompanying anterior cruciate ligament rupture, and in case that rupture length was below 2 cm, rates of clinical cure and patients subjective satisfaction were significantly high. In case of complex or degenerative rupture, patients satisfaction rates were higher when comparing with clinical cure rates. Conclusion: Various sutures are possible as well as available in case of arthroscopic meniscal inside to out repair using nonabsorbable suture material. It can be concluded that patients age is not absolte consideration in determining the suture of meniscus. In cases of complex rupture, degenerative rupture, ruptures companied by joint-cartilage injuries, considerate consideratin need be paid to choose patients and operations.

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.
