Purpose : To evaluate the efficacy of arthroscopic management of the triangular fibrocartilage complex(TFCC). Materials and Methods : Thirteen patients(14 wrists) with acute or chronic traumatic triangular fibrocartilage complex lesions were included in the study. The mean patients' age was 28.3 years, with a range of 21 to 45 years. All patients were diagnosed by physical examination, arthrographic or magnetic resonance imaging studies. Eight of the 14 wrists had central TFCC tear while 6 wrists had peripheral tear. Under arthroscopic control, injuries to the central portions were treated by debridement and excision of unstable tissue fragment while peripheral tears were repaired. The follow-up period averaged 28 months. The results were analyzed clinically using the Mayo modification of the Green and O' Brien wrist scoring system. Results : Nine of the 14 wrists were rated excellent,3 good and 2 fair Overall, 12 of the 14 patients rated as satisfactory and returned to sports or work activities. Conclusion : Arthroscopic treatment of TFCC resulted in a high degree of patient satisfaction and an increase in the ability to perform at workshop.

Purpose : To propose the diagnosis, 'hypertrophy of the anterior cruciate ligament(ACL)', and its clinical, radiological and pathological characteristics. Materials & Method : Since Dec. 1995, we have experienced 10 patients(12 knees) with hypertrophy of the ACL. There were 2 males and 8 females, and the age of the patients ranged from 35 to 67 years. Characteristics of clinical, radiological and pathological findings were analysed. Results : The chief complaint was insidious onset of dull pain on the knee which became worse with activity. The constant physical finding was painful limitation of full extension of the knee. Sagittal MR images showed diffuse swelling of the ACL, similar finding that could be seen in acute ACL tear. Arthroscopically, noted was a marked enlargement of the ACL causing notch impingement. Biopsies of the hypertrophied ACL showed increased collagenous tissue with variable degree of myxoid degeneration. With partial excision of the hypertrophied ACL with or without notchplasty, the symptoms improved in all. Conclusion : Hypertrophy of the ACL, a newly proposed diagnosis, should be considered be determining the cause of the painful knee, and further study should be done about its pathogenesis.

Purpose: To report the usefulness of dynamic ultrasonography in subluxation of the long head of the biceps tendon, which is difficult to detect with static imaging such as plain radiography, static sonography, MRI and in a subtle physical examination. Materials and Methods: Two male patients suffered from subluxation of the long head of the biceps. This difficult diagnosis? was managed by surgery (biceps soft tissue tenodesis) with the aid of dynamic ultrasonography. At final follow up, we evaluated patients' symptoms and functional outcomes using KSS, UCLA and ASES scores. Results: We diagnosed and treated subluxation of the long head of the biceps easily using dynamic ultrasonography. At the final follow up, both patients' symptoms and functional outcomes were improved. There were no significant complications. Conclusion: Dynamic ultrasonography is a useful method in the difficult and subtle diagnosis of subluxation of the long head of the biceps.

The meniscal cyst of knee joint is a rare disease, and the discoid meniscal cyst has not been reported in Korea. We report 3 cases of the discoid meniscal cyst confirmed by MRI and arthroscopy. In physical examination, all cases have tenderness of the knee joint. One has palpable mass of knee joint and the other one has limitation of knee motion with knee flexion contracture of 10 degrees and positive McMurray test at external rotation of the knee. All cases are complete discoid meniscus, which are, one medial discoid meniscus and two lateral discoid meniscus through MRI. We confirmed horizontal tear of meniscus in all cases and the location of meniscal cysts are anterior hem of meniscus in one and body of meniscus in two. We could get excellent results in all 3 cases that return to normal knee range of motion.

Objectives: Obstructive sleep apnea syndrome(OSAS) is known to be associated with the changes of autonomic nervous system (ANS). Nasal continuous positive airway pressure(nCPAP) treatment was found to correct abnormal ANS changes in OSAS but it remains to be further clarified. We aimed to assess the effects of nCPAP on ANS manifested on electrocardiogram, using spectrum analysis in the subjects with OSAS. Methods: Digital polysomnography was performed in 18 patients with OSAS(mean age $43.7{\pm}16.6$ years ; 17 males, 1 female ; mean respiratory disturbance index (RDI) $48.6{\pm}20.9$) for one baseline and another CPAP nights. From each night, 300 continuous beats of ECGs without artifact were chosen from both stage 2 sleep and REM sleep and they were used for power spectrum analysis. We compared between baseline and CPAP nights the heart rate variability including VLF(very low frequency power), LF (low frequency power), HF(high frequency power), R-R means, R-R variance, and LF/HF ratio, using Wilcoxon signed ranks test. Results: In all patients, nCPAP proved to be effective in relieving apneas and snoring. During nCPAP night compared with baseline night, decreases in VLF(p<0.05), LF(p<0.01), and R-R variance(p<0.05) were found in stage 2 sleep, and decreased LF(p<0.05) was found in REM sleep. No significant differences in each sleep stage were found in other variables between the two nights. Conclusion: Our findings suggest that OSAS increases the activity of sympathetic nervous system and nCPAP application effectively decreases the activity. And nCPAP does not appear to influence the parasympathetic nervous activity in OSAS.

Purpose : Orbital cellulitis is rare, but it could be from the serious complication of sinusitis in children. It is often difficult to distinguish periorbital cellulitis from orbital cellulitis. The purpose of this study is to describe the clinical features of orbital and periorbital cellulitis in a pediatric population and to assess the predisposing factors and their complications. Methods : Forty-one patients aged 18 years and younger who were admitted between January 2000 and December 2006 to Hanil General Hospital and Kyunghee University Hospital with orbital or periorbital cellulitis. The retrospective analyses included clinical characteristics of orbital and periorbital cellulitis, dermographics, past history, predisposing factors, clinical presentations, treatments, and complications. Results : Among 41 patients, 34 patients had periorbital cellulitis, 7 patients had orbital cellulitis. While paranasal sinus disease was the most common predisposing cause in orbital cases, skin lesion, insect bite, dacrocystitis and conjunctivitis were the common causes in periorbital cases. In comparison with periorbital cases, orbital cases had higher level of white blood cell count, erythrocyte sedimentation rate, and C-reactive protein. Blood cultures were taken in 23 patients, but only one had Staphylococcus aureus from blood. Only one case had surgical incision and drainage and recovered without complications. Conclusion : From the results of our data, when patient shows erythematous swelling of periorbital area with opthalmoplegia, chemosis and proptosis, orbital CT scan is required to make diagnosis of orbital cellulitis. Most cases of orbital cellulitis can be treated successfully without surgical intervention. If there is no clinical improvement, repeated CT scan and/or surgical intervention should be considered.

Background: The incidence of mycoplasmal pneumonia is predominantly at childhood and early adulthood, but in adults, its incidence is low and its symptoms and physical findings are nonspecific. The definite diagnosis of M. pneumoniae pneumonia can be made by sputum culture, but requires several weeks for positive results, and the early diagnosis must initially be based on the serologic tests and appropriate clinical findings. Thus, we evaluated the clinical aspects of M. pneumoniae pneumonia in the adults patients. Method: Among the admitted patients due to pneumonia, the definite diagnosis is anti-M. pneumoniae antibody titer of $\geq$ 1:40 and a single cold agglutinin titer of $\geq$ 1:64. The presumptive diagnosis is anti-M. pneumoniae antibody titer of $\geq$ 1:40 or a single cold agglutinin titer of $\geq$ 1:64 and the clinical characteristics or chest X-ray findings are compatible with M. pneumoniae pneumonia. We studied the age and sex distribution, seasonal distribution, clinical symptoms, physical findings, serologic test, chest X-ray findings, treatment and its progression. Results: 1) The age distribution was even and the ratio of male to female was 1:1. 2) The monthly distribution was most common in January(16.7%) and the seasonal distribution in autumn and winter(autumn: 30%, winter: 33.3%). 3) The cold agglutinin titers were higher than 1:64 in 12 cases(40%), and reached the peak level around 2 weeks from onset and antimycoplasma antibody titers were higher than 1:160 in 5 cases(16.7%). 4) On the chest X-ray, pulmonary infiltration was noted in 28 cases(93.3%) among 30 cases and right lower lobe involvement was the most common(33.3%) and both lower lobe involvement was noted in 7 cases(23.3%). 5) The mean treatment duration was most common(33.3%) in 1 week to 2 weeks after admission and 26 cases(86.7%) were improved within 4 weeks. 6) On admission, there was fever(${\geq}38.9^{\circ}C$) in 17 cases(56.7%), and the fever subsided in 12 cases(70%) within 3 days after treatment using erythromycin. Conclusion: The mycoplasmal pneumonia in adults shows milder clinical patterns than that in childhood and can be completely recovered without complication by early diagnosis and treatment.

Purpose: In case of anterior cruciate ligament (ACL) reconstruction, graft tendon is generally fixed in tibial tunnel with knee extended. When reconstructing ACL using hamstring tendon, the authors aim to find out the effect of knee joint position during graft fixation on postoperative knee joint stability and range of motion. Materials and Methods: Prospective study was done on patients who have undergone ACL reconstruction using hamstring tendon from May 2002 to January 2003 We used Rigifix system (Mitek Product, Johnson and Johnson, USA) and Intrafix system for fixation. Thirty nine patients received ACL reconstruction during this period. Excluding 2 patients lost in the follow-up, 37 patients were analyzed. The mean follow-up period was 14 months $(13{\sim}25months)$. Knee position was decided alternatively without any bias. Clinical evaluation was based on Lachman test, pivot shift test, Lysholm score, IKDC(international knee documentation committee) assessment and side to side KT-1000 maximal manual arthrometer difference. Results: After the last follow-up, average postoperative Lysholm score was 93.1 poins(65-98points). According to IKDC score, 26 cases were normal, 10 cases were nearly normal, 1 case was abnormal and we had no case of severe abnormality. The mean difference from the normal side was 2.5 mm under maximal manual loading KT-1000 arthrometer. According to postoperative Lachman test, 32 cases were normal,2 cases were grade I and 1 case was grade II. There were 34 cases of normal, 2 cases of grade I and 1 case of grade II. When using maximal manual KT-1000 arthrometer side to side difference, the difference from the normal side while fixing the tibia at 20'knee flexion was 2.3 mm and at full extention the difference was 2.7 mm. The range of motion at postoperative 1 year showed 5 degree flexion contracture in 1 case at 20 degrees knee flexion and 10 degrees of flexion limitation was observed in 2 cases at full extension. Conclusion: When ACL reconstruction using autogenous hamstring tendon, anterior laxity showed no difference in its stability between two groups. Tibial side fixation at full extension may be helpful in preventing flexion contracture due to overconstrained graft tendon.

Purpose: The purpose of this study is to compare the results of the arthroscopic reconstruction of ACL using autologous hamstring tendon and autologous bone-patellar tendon-bone. Materials and Methods: From January, 2000 to December, 2004, 120 patients underwent arthroscopic ACL reconstruction using autologous hamstring tendon(60 cases) and autologous bone-patellar tendon-bone(BPTB)(60 cases). The mean followed up period of hamstring tendon group was 42 months(range $24{\sim}69$ months) and patellar tendon group was 52 months(range $24{\sim}84$ months). At the time of the final follow up, sixty patients in each group were evaluated the results of physical examination, activity level, patients' satisfaction, functional status, and objective anteriror stability using KT-2000 arthrometer. Results: At the time of the final follow up we compared the two groups who had ACL reconstruction using either autologous hamstring tendon or BPTB, and the final results of the Lachman test showed negative, or mildly positive in 85%(51 cases) of the hamstring tendon group and 90%(54 cases) of the BPTB group. Pivot shift test indicated positive in both groups, 8%(5 cases) and 5%(3 cases) respectively and showed no statistically significant difference. The evaluation of the anterior laxity using the KT-2000 arthrometer revealed no significant difference in the hamstring and BPTB groups: differences less than 3 mm compared to the healthy side were 85%(51 cases) and 90%(54 cases)(p>0.05). The Lysholm score improved from a preoperative score of 51 to a postoperative score of 79.1 in the hamstring groups and from 52 to 82.2 in the BPTB groups. According to the IKDC rating system, 87%(52 cases) were normal or near normal in the hamstring group. In the BPTB group, 83%(50 cases) were normal or near normal. The Tegner score for the hamstring groups was 4.8 preoperatively and 7.1 at the final follow up, and the Tegner score for the BPTB groups was 4.5 preoperatively and 7.3 after the last follow-up. The anterior knee pain was found in 7%(4 cases) in the hamstring tendon group and 10%(6 cases) in the patellar tendon group. Conclusion: Arthroscopic ACL reconstruction using both the autologous hamstring tendon and the patellar tendon during their mid term follow up period demonstrated excellent results. However, the final results during their last follow up showed no statistically significant difference between the two groups.
