Osteosarcoma probably arises from a primitive, undifferentiated mesenchyme, It is highly malignant bone tumor characterized by the invariable formation of neoplastic osteoid and tumor tissue with poor prognosis. Osteosarcoma may involve any bone, but usually arises in the metaphyseal portion of long bones, most frequently at the distal ent of the femur, the proximal end of the tibia, and the proximal end of the humerus. The authors have experienced one case (52 year old male) of osteosarcoma originating from the right patella.

Various methods have been described for sugical management of patients who have recurrent anterior shoulder dislocation. In recent years, great advancements have been made in arthroscopic surgery of anterior shoulder dislocation. From June, 1987 to December, 1989, 10 shoulders in 10 patients who experienced recurrent traumatic anterior dislocation were repaired with the arthroscopic stapling technique. Among them, 6 cases which could be followed for more than 1 year were analyzed. Postoperstive follow-up averaged 21 months (range 1 year to 3 years). The results were summarized as follows: l. Average patient age was 24 years with an age range from 20 to 31 years. All 6 cases were male. 2. The orighinal dislocation involved an injury in all cases. It had occurred between 18 months and 6 years before surgery. Every patients had had 4 or more recurrences. 3. Among the 6 cases, 5 cases were found to have a Bankart lesion and 3 cases, a Hill-Sachs lesion at surgery. 4. There have been no postoperative recurrence up to date. 5. 7 and 10 degrees restriction in external rotation, as compared to the contralateral shoulder, was noted in 2 patients. 6. Clinical results of 6 cases, based on the Rowe shoulder rationg system, were 4 excellent and 2 good. 7. No instances of infection, instrument failure, or major neurovascular complications occurred in this series.

Visual perception is a complex process engaging many different aspects of brain functioning. Like other cognitive functions, the extensive cortical distribution and complexity of visual perceptional activities make them highly vulnerable to brain injury. Dectection and characterization of perceptual require careful assessment as well as the application of selected neuropsychological tests. In the article we reviewed neuropsychological assessment of visual perception and constructional abilities. And the principal visuospatial disorders are discussed, the associated neuropsychiatric disorders are presented.

The anterior cruciate ligament integrity is critical to the mechanics, stability, and protection of the joint and its periarticular structure. The insufficiency of the anterior cruciate ligament leads to a disintegration of the rolling/gliding movement, and followed by degenerative changes of the joint cartilage. Numerous surgical procedures have been designed to control the anterior cruciate ligament insufficiency. None has yet been generally accepted as the best procedure. Arthroscopy has added a new dimension to knee surgery and earned a rightful place in the diagnosis and mansgement of the anterior cruciate ligsment problems. In this article, we present the results in twenty two patients who were treated with staple by arthroscopic surgery from January, 1984 to December, 1985. The results obtained were as follows : 1. Type of surgery were 2 cases of primsry repair, 12 cases of pedicle graft, and 8 cases of semitendinosus graft. 2. Associated lesions were 17 cases(77.3%) of meniscal injuries and 3 cases(13.6%) of the injury to the articular cartilage. 3. Clinical results were excellent and good in 12 cases(54.5%) and fair in 8 cases(36.4%) by the Hospital for Special Surgery knee follow up score. 4. Advantages of using the Ligamentous and Cagsular Repair system for anterior cruciate ligament insufficiency were A) Minimal surgical exposure and trauma. B) Less painful. C) Utilized the patients own collagen tissue with vascularity and synovial covering. D) Close approximation of normal anterior cruciate attachment. E) Excellent bony fixation. F) Rapid rehabilitation. G) Minimal morbidity and few complications. On the basis of our findings, we advocate the arthroscopic repair % reconstruction with staple as a reliable and effective method of treating anterior cruciate ligament insufficiency.

The role played by synovial plica in internal derangement of the knee has been increased recently. A clinical application of arthroscopy of the one hundred eighty patients were performed, and eighteen patients with a symptomatic plica were successfully managed and followed by arthroscopic surgery at the department of orthopaedic surgery, Soon Chun Hyang University Hospital from May 1983 to May 1984. The results were summerized as follows; 1. Arthroscopy is the most accurate diagnostic and operative methods for the investigation of the incidence, pathology, clinical significance and treatment of the synovial plica. 2. The incidence of the mediopatellar plica in our view was 41% that is, 74 of 180 symptomatic knee. 3. Arthroscopy is a practical and valuable procedure with minimal associated morbidity or complication. 4. The increased accuracy of diagnosis help to avoid unnecessary operations and to be basic methods of treatment on a better knowledge of the pathology.

The application of the arthroscope to the shoulder joint has evolved in recent years for the purpose of diagnosis and treatment. This paper presented 11 cases with various shoulder diseases treated by arthroscopy during the period from January, 1984 to September, 1985 in the Department of Orthopedic Surgery, College of Medicine, Soon Chun Hyang University. The advantages of the arthroscopy were as follows: 1. The arthroscopy made it easier to diagnose the unsolved cases by direct biopsy on the pathologic lesions in the joint. 2. The damage on the inside and outside of the shoulder joint was minimal and the post-operative incision scar was acceptable cosmetically. 3. The limitation of the joint motion did not remain due to early exercise post-operatively. 4. The complications such as infection, neurovascular injury, scuffing of joint cartilage, etc. could be avoided.
