Acute ankle sprain is the most common injury in the lower extremities, and approximately 10% to 40% of acute lateral ankle ligament injury causes chronic pain or instability. For chronic symptoms lasting after an acute sprain, the possibility of joint damage, such as bony structures, ligaments, cartilage, and nerves around the ankle joint, should be considered. Patients with chronic lateral ankle instability usually complain of repeated sprains or giving way sensations. There has been steady progress in the treatment options until recently, however new treatments are still being attempted. This paper describes the causes, diagnosis, and recent trends in the conservative and operative treatment of chronic lateral ankle instability.

The natural history of the anterior cruciate ligament(ACL)-deficient knee remains controversial. although numerous investigation have tried to ascertain the course that the knee would follow once the ACL has lost functional integrity. An extensive review of the literature performed according to symptoms. physical examinations, associated surrounding tissue injuries. returns to activity level and radiological changes in the knee joint. An active individual with a non-functioning ACL was susceptible to injury to the menisci and deteriorate the articular cartilage, followed radiographic changes. An activity levels in general also changed after injury. The most common symptom was pain. But instability varied in these individuals. Conclusively we believe that all these factors will eventually, if not initially, result in a symptomatic knee. which will result in significant limitations to the individual's desired level. So we recommend an aggressive approach in person who desired to return to a relatively active life style in young person as well as in middle aged individuals who have significant symptomatic ACL deficient knee.

Objective: To quantitatively assess biochemical alterations in the cartilage of the subtalar and midtarsal joints in chronic lateral ankle instability (CLAI) patients with isolated anterior talofibular ligament (ATFL) injuries and combined calcaneofibular ligament (CFL) injuries using MRI T2 mapping. Materials and Methods: This study was performed according to regulations of the Committee for Human Research at our institution, and written informed consent was obtained from all participants. Forty CLAI patients (26 with isolated ATFL injuries and 14 with combined ATFL and CFL injuries) and 25 healthy subjects were recruited for this study. All participants underwent MRI scans with T2 mapping. Patients were assessed with the American Orthopedic Foot and Ankle Society (AOFAS) rating system. The subtalar and midtarsal joints were segmented into 14 cartilage subregions. The T2 value of each subregion was measured from T2 mapping images. Data were analyzed with ANOVA, the Student's t test, and Pearson's correlation coefficient. Results: T2 values of most subregions of the subtalar joint and the calcaneal facet of the calcaneocuboid joint in CLAI patients with combined CFL injuries were higher than those in healthy controls (all p < 0.05). However, there were no significant differences in T2 values in subtalar and midtarsal joints between patients with isolated ATFL injuries and healthy controls (all p > 0.05). Moreover, T2 values of the medial talar subregions of the posterior subtalar joint in patients with combined CFL injuries showed negative correlations with the AOFAS scores (r = -0.687, p = 0.007; r = -0.609, p = 0.021, respectively). Conclusion: CLAI with combined CFL injuries can lead to cartilage degeneration in subtalar and calcaneocuboid joints, while an isolated ATFL injury might not have a significant impact on the cartilage in these joints.

Injury of posterolateral corner is unusual, but it can cause disability due to severe instability and cartilage damage. However, the anatomical structures, diagnosis and treatment have not defined clearly yet. Posterolateral corner injury is regarded as the one of main factor to the results of failure in cruciate ligament reconstcution if it was undiagnosed and untreated. Diagnosis of postetolateral corner injury is consists of physical exam, radiographic finding, MRI, and arthroscopic findings. The treatment method of of postetolateral corner injury depends on the time and severity of injury. Anatomical reconstruction of posterolateral corner shows the better clinical outcome than non anatomical reconstructions, but the clinical results of long term follow up is still needed. Therefore, the aim of this article is to review the recent literatures and to organize diagnosis and treatment of posterolateral corner injury.

Sports-related knee injuries frequently occur in adolescent period and fractures are more common than ligamentous Injuries in this age group because of physiologic characteristics. We operated an adolescent soccer player with lateral femoral epiphyseal injury using arthroscopic assisted reduction and infernal fixation. In $2^{nd}$ look arthroscopy and metal removal at postoperative 2 years, articular cartilage was healed with good congruity and lower extremity entire long film showed normal axial alignment without residual deformity.

Superior labrum anterior to posterior (SLAP) lesions of the shoulder has recently been a popular issue to shoulder surgeons. Now we are correlating many shoulder symptoms to this SLAP lesion. A 45 year-old female patient injured her shoulder when her arm sleeve was entrapped in moving automobile door. A forceful pull of the arm in external and abduction position was suspected. She complained continuous shoulder pain with limited range of motion for 2 months. Magnetic resonance image showed possible SLAP lesion but no definite diagnosis were made prior to the operation. Arthroscopic evaluation revealed SLAP type Ⅱ lesion with concomitant avulsion of the superior glenoid cartilage. In addition anterior labrocapsular tear was seen from 7 to 9 o'clock of anterior glenoid. The SLAP lesion and the anterior capsulolabral lesion were repaired properly to the glenoid. We report a case of glenoid-cartilage avulsion type of SLAP Ⅱwith anterior labrocapsular lesion.

Osteochondral lesion of the talus (OLT) is a broad term used to describe an injury or abnormality of the talar articular cartilage and adjacent bone. Various terms are used to describe this clinical entity, including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. Several treatment options are available; the choice of treatment is based on the type and size of the defect and the treating clinician's preference. Arthroscopic microfracture (a bone marrow stimulation technique) is a common and effective surgical strategy in patients with small lesions or in those in whom non-operative treatment has failed. This study had the following aims: 1) to review the historical background, etiology, and classification systems of OLT; 2) to describe a systematic approach to arthroscopic bone marrow stimulation for OLT; and 3) to determine the characteristics that are useful for assessing osteochondral lesions, including age, size, type (chondral, subchondral, cystic), stability, displacement, location, and containment of the lesion.

With the adevance of widespread mechanization and high-speed era, the incidence of traumatic rupture of the tracheobronchial tree has been increased considerably. We have experienced these diseased of the 3 cases in our department. The first case was a 25 year old male who was severe dyspneic and subcutaneous emphysema, hemoptysis, and hemopneumothorax of both side were noted. During tracheostomy, it was found that the 2net ring of the trachea was ruptured. No definitive procedure was made on admission. Corrective surgery was performed with end-to-end anastomosis on 31 post-traumatic day. The second case was a 43 year old female who received multiple stab wounds on the anterior neck and it was found that the cricoid cartilage was transected partially. The injured cartilage was approximated with interrupted suture of No. 600 wire. The third case was a 19 year old male who had sustained a compression chest injury without external wound or rib fracture. At five days after trauma, he had suffered from dyspnea, and obstruction of the left main bronchus due to traumatic bronchial rupture was confirmed by means of bronchoscopy and bronchography at two weeks after the trauma. End-to-end anastomosis of the bronchus was performed and the left lung was aerated well. Mild postoperative stenosis of trachea was remained in the first case. Others were uneventful.

As many people keep small dogs as pets, dog bites are common injuries, accounting for approximately 80%-90% of all animal bite injuries. These injuries usually occur on the upper extremities, most commonly on the fingers. Most of these injuries appear as simple lacerations or abrasions of the skin. Common symptoms include inflammatory reactions of the soft tissue, such as pain, swelling, erythema, and cellulitis. However, the complications of small dog bites may include joint or cartilage injuries, including acute osteomyelitis. Once osteomyelitis develops, it is difficult to diagnose since it has a latency period of approximately 2 weeks. Plain radiography, magnetic resonance imaging, and 3-phase bone scans should be performed when acute osteomyelitis is suspected, and broad-spectrum empiric antibiotic treatment should be administered for approximately 8-12 weeks. We report 3 very rare cases of acute osteomyelitis that occurred after a dog bite injury.

Although hemothorax and pneumothorax are common complications seen in rib fractures, focal extrapleural hematoma is quite rare. We report a 63-year-old female patient that developed large focal extrapleural hematoma after falling off a second floor veranda. The patient had sustained 3, 4, 5th costal cartilage rib fractures and a sternum fracture. She had developed suspected empyema with loculations with small amount of hemothorax. She underwent a planned early decortication/adhesiolysis by video assisted thoracoscopic surgery at the 12th post-trauma day due to failed drainage. Unexpectedly, she had no adhesions or any significant retained hematoma mimicking a mass, but was found with the focal extrapleural chest wall hematoma. She was discharged on postoperative 46th day for other reasons and is doing fine today.
