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.

Purpose : To analyze the clinical results of isolated lateral meniscus injury according to discoid versus non-discoid, athletes versus non-athletes and repaired cases versus cases treated with meniscectomy. Materials and Methods : Between January 1997 and June 2000, arthroscopic lateral meniscus surgery was performed in 329 cases. We reviewed 80 cases of isolated lateral meniscus injury without associated ligament injury or other pathologic condition retrospectively. The study population was composed of 54 males and 26 females with average age of 30.2 years(range, $17\~40$ years). Average follow up period was 15 months(range, $12\~39$ months). Eighty cases were classified into three categories; discoid group versus non-discoid group, athletes versus non-athletes, repaired cases versus cases treated with meniscectomy. Clinical evaluation was performed using Lysholm knee score and Tegner activity. Results : Non-discoid group had higher incidence of longitudinal tear than discoid group. Athletes group had higher incidence of repaired cases than non-athletes group. The repaired group had better clinical result than patient treated with meniscectomy group. Conclusion : Although lateral meniscus has some special features including anatomic mobility which can cause instability after meniscectomy and technical difficulties in repairing, it is recommended repairing meniscus tear not only longitudinal but also horizontal and complex tear to obtain better clinical results.

Either absorbable or nonabsorbable sutures can be used in meniscal repair. Some surgeons prefer nonabsorbable sutures because they believe that nonabsorbable sutures improve meniscal healing as compared with absorbable sutures. But, permanent existence of sutures in the lesion could make problems. We report a case of Inside-Out meniscus repair that nonabsorbable sutures came out of the joint capsule tearing the substance of the meniscus.

The current treatment of extensive meniscal injuries has resulted in numerous investigations and clinical trials to restore normal meniscal functions. A cryopreserved meniscal allograft transplantation is one of the successful methods available to restore the meniscus. All the procedures of 26 cases were performed in an minimal open fashion, though initial four cases were done with the aid of arthroscope. In all of the grafts, we used a bone bridge which was attached to meniscus for better stability and healing. Anterior cruciate ligament reconstructions were also performed simultaneously with the meniscal procedures. We attempted to minimize articular cartilage by employing so called the "Key-hole technique" for the medial meniscus transplantation. First, the meniscal cartilage bone bridge was shaped into a cylinder and a bone tunnel was made just beside the medial border of the anterior criciate ligament insertion of the recipient knee joint, and the bone bridge of the meniscal cartilage was push to press-fit. The inserted meniscal cartilage was sutured by the usually employed technique under arthroscopic control. The lateral meniscus was shaped different to the medial meniscus in that the bone bridge was semicylindrical and the bone trough was made beside the lateral border of the anterior criciate ligament insertion of the recipient knee joint. The meniscus was put into the bone trough and the leading suture was extracted anterior to the tibia and tied the knot. The inserted meniscus was sutured in the same manner as the medial meniscus transplantation. By the above described method, the authors were able to minimize the articular cartilage invasion and transplant the meniscus with relative accuracy.

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.

The posterior root of medial meniscus maintains normal meniscal function by circumferential hoop tension and prevents extrusion of meniscus and progression of osteoarthritis. A complete tear of posterior root of medial meniscus leads to loss of hoop tension, it is important to repair it and preserve the function of the medial meniscus. Recently, a variety of arthroscopic assisted reduction and repair techniques have been used. We create an arthroscopic all-inside suture technique using a 18 gauge spinal needle and suture anchor that is easier and more convenient compared with the previous techniques. So we report this technique with a review of current literatures.

Purpose: This study is to evaluate the clinical findings of media] meniscus root tear, pull-out repair technique and it's short term results. Materials and Methods: From September 2003 to August 2004, 23 cases of total 27 medial meniscus root tears were treated by pull-out repair technique. Mean age was 60.2 years old. The pull-out technique was divided into 2 groups In group 1(14/23 cases), anterolateral portal was used and in group 2(9/23 cases), anterolateral and posteromedial portals were used for bed preparation. Concomitant cartilage lesions were documented as ICRS mapping system. The clinical outcomes were evaluated according to Lysholm Knee Score. Results: The postoperative Lysholm Knee Score was 77.1(range; $58{\sim}97$) in group 1 and 81.4(range; $72{\sim}94$) (p>0.05). The failure rate was 3 of 14 cases(21.4%) in group 1 and 1 of 9 cases(11.1%) in group 2. Twenty of 22 cases(90.9%) showed cartilage lesions in weight bearing portion of medial femoral condyle which were 8 grade III and 5 grade IV according to the Outerbridge classification. Conclusion: Pull-out repair seems to be a useful treatment of the medial meniscus root tear for preservation of circumferential hoop tension of meniscus.
