The most commonly used graft source for anterior cruciate ligament reconstruction is the autogenous bone- patellar tendon-bone graft unit. Despite a good success record, intraoperative technical errors and postoperative complications have been known. Author analyzed intraoperative technical errors and postoperative complications, in 44 patients who were treated at the department of orthopaedic surgery, chosun university hospital from Jan. 1994 to Jun. 1996. The most common intraoperative technical errors was screw graft divergency in 5 cases. Other intraoperative technical errors were too anteriorly location of femoral tunnel in 1 case, too anteriorly location of tibial k femora) tunne.l both in 1 case, graft tunnel mismatching in 1 case, graft pullout in 1 case and partial destruction of posterior cortex of femoral tunnel in 1 case, fracture of the bone plug in 1 case. The most common postoperative complication was patellar tendinitis in 20 cases (45.5%). Other postoperative complications were anterior knee pain in 14 case. (31.8%), patellar crepitation in 12 cases (27.3%), quadriceps atrophy in 9 cases (20.5%), arthrofibrosis in 3 cases and graft failure in 2 cases. Author concluded the causes of intraoperative complications were technical errors, and anteriorly location of graft tunnel is most influenced factor to final fuctional results. To eliminate the postoperative complications, intraoperative technical errors should be avoided and also accelerated rehabilitation should be done.

A 2-month-old Korean boy presented with a solitary papule on the cheek which was noted at birth. Histopathologic findings were consistent with angiofibroma of fibrous papule of the face (FPF). FPF is known to affect adults, and congenital occurrence has not been reported to the best of our knowledge. We report a case of congenital FPF which showed a facial papule clinically and an angiofibroma histologically.

PURPOSE: To evaluate the effect of autotransfusion system in minimally invasive total knee arthroplasty (TKA). MATERIALS AND METHODS: Seventy-one patients who underwent unilateral minimally invasive TKA between October 2009 and June 2010 were selected. The first group included 36 patients who received standard vacuum drainage and the second group, 35 patients who underwent autologous retransfusion drainage. In the first group, allogeneic blood transfusion was performed if the postoperative hemoglobin level was <7.0 g/dL or 7.0-8.0 g/dL with the presence of a medical complication and an anemic symptom. The second group received autotransfusion and allogeneic transfusion additionally according to the same criteria. Changes in the pre- and postoperative hemoglobin level, amount of auto- or allotransfusion, and frequency of allogeneic transfusion were assessed. RESULTS: Allogeneic transfusion was required in 13 patients (36.1%) in the first group and four patients (11.4%) in the second group. The mean allogeneic transfusion volume was significantly low in the second group compared to the first group (64.4 mL vs. 278.9 mL; p<0.05). The hemoglobin level on the 1st postoperative day compared to the preoperative level decreased by 22.6% in the first group and 11.7% in the second group. The postoperative hemoglobin level was higher in the second group (p<0.05). CONCLUSIONS: Minimally invasive unilateral TKA with an autotransfusion system can be beneficial in patients with no medical complications because of the decreased allogeneic transfusion.

Purpose:
This study examined the clinical and radiological outcomes of TFNA (Trochanteric Fixation Nail-Advanced) and PFNA-II (Proximal Femoral Nail Antirotation-II) used in the treatment of unstable intertrochanteric femur fractures. The association between lateral screw sliding and lateral trochanteric pain was analyzed.
Materials and Methods:
The study included 116 patients diagnosed with unstable intertrochanteric femur fractures who underwent intramedullary nailing surgery at the author’s hospital. The patients were divided into two groups: 72 who received PFNA-II and 44 who received TFNA. Ten patients with positive greater trochanter tenderness and 106 patients with negative tenderness were assessed for the factors associated with lateral trochanteric pain. The radiological outcomes included an evaluation of fracture union, screw position, tipapex distance, proximal femoral nail protrusion, and lateral sliding length of the helical blade. The clinical outcomes were assessed using the Harris Hip Score, visual analogue scale (VAS) score, greater trochanter tenderness, and pre- and postoperative ambulation ability.
Results:
Thirty-three patients (45.8%) of the PFNA-II group and 18 (40.9%) of the TFNA group had lateral sliding of the helical blade, with no significant difference between the two groups (p=0.604). The VAS score was significantly higher in the TFNA group (3.77±1.71) than the PFNA-II group (3.10±1.57, p=0.032). Furthermore, the prevalence of a positive greater trochanter tenderness was significantly higher in the TFNA group (seven patients) than in the PFNA-II group (3 patients, p=0.04). Eight patients had lateral sliding in the positive greater trochanter tenderness group, whereas 43 had lateral sliding in the negative greater trochanter tenderness group (p=0.030). The lateral sliding length was 8.87±5.22 and 2.68±4.47 in the positive and negative groups, respectively (p<0.001).
Conclusion
The PFNA-II and TFNA groups showed favorable clinical and radiological outcomes, suggesting that both devices are suitable for treating unstable intertrochanteric femur fractures. A comparison of the two devices showed that TFNA induces more lateral trochanteric pain than PFNA-II, and the presence and extent of lateral sliding were associated with lateral trochanteric pain.

BACKGROUND: Among the various mechanisms of Myocardial reperfusion injuries, neutrophil is thought to be one of them. Endogenous coronary vasodilator adenosine is known to have myocardial protective effect through variable pharmacologic action, influencing the function of several cell types involved in the pathogenesis of myocardial reperfusion injury. This study was designed to determine the beneficial effect of adenosine on the left ventricular function during reperfusion and whether this effect is due to the adenosine on the role of neutrophil. METHODS: 27 open-chest cats were randomly divided into 3 groups. 6 cats received ischemic injury without reperfusion(group 1). 21 cats were subjected to 60 minutes of proximal left anterior descending coronary artery occlusion followed by a 60-minute reperfusion. 11 of 21 cats received intravenous adenosine(0.15mg/Kg/min) infusion starting 5 minutes before reperfusion throughout the entire period(group 3). 10 cats received equal volume of saline instead of adenosine(group 2). RESULTS: 1) During the experimental period, significant decrease of heart rate, blood pressure, RPI, negative dP/dT and increase of LVEDP were noted in group 2 and 3 with no difference between the two groups. The reduction of positve dP/dT was more significant in group 2 at 30 and 60 minute of reperfusion than the preocclusion value(1404+/-111, 1631+/-161 vs 1832+/-169mmHg/sec at baseline, p<0.05). In contrast, positive dP/dT in group 3 at 30 and 60 minute of reperfusion were similar to baseline values(1890+/-92, 2052+/-112 vs 2025+/-227mmHg/sec at baseline, p=NS). These were significantly higher(p<0.05) than untreated group 2. 2) Infarct size was significantly reduced in adenosine-treated group 3, when expressed as a percentage of the area at risk(28.4+/-3.3% vs 44.5+/-3.2% of group 2, p<0.05). The significant increase in myeloperoxidase activity observed after reperfusion was not detected in adenosine treated group 3.(0.18+/-0.05 vs 0.46+/-0.09 unit/100mg wet tissue weight, p<0.05). A significant correlation was present between infarct size (% of left ventricle) and myeloperoxidase activity(r=0.72, p<0.01). 3) Light microscopic examination demonstrated the decreased acute interstitial and intra vascular inflammatory infiltration and capillary plugging together with decreased tendency of incidence of contraction band necrosis in adenosine treated group 3. CONCLUSION: These findings suggest that intravenous administration of adenosine during the early reperfusion period significantly reduces infarct size, improving the early recovery of global ventricular function. The probable cause is the effect of adenosine on neutrophil as one of the various protective mechanisms of adenosine in feline heart model subjected to coronary occlusion and reperfusion, 60 minutes each.

Journal of the Korean Fracture Society 2010;23(1):34-41
PURPOSE: We wanted to evaluate the efficacy of MIPO (minimal invasive plate osteosynthesis) technique by LCP (locking compression plate) for treating proximal tibia fractures. MATERIALS AND METHODS: Twenty-three patients, who had operation due to proximal tibia fracture and available for follow up for more than 1 year were included in this study. Cause of injury and accompanied injuries were checked. Operation time, period to bone union, range of joint motion and alignment were evaluated with complications. RESULTS: Mean bone union time was 13.7 weeks (10~20). Twenty-one cases of the patients showed angulation of less than 5 degrees and 17 cases had normal range of motion. Five cases showed skin irritation by the plate and 2 cases had superficial infection. CONCLUSION: LCP by MIPO technique for treating proximal tibia fracture showed excellent results. Delicate technique is required for the proper adjustment of LCP and the alignment of the lower leg.

Pulmonary embolism is the impaction of material into branches of the pulmonary arterial bed. It usually occurs in patients with primary hypercoagulable states or secondary hypercoagulable states like cancer, preganancy, and estrogen replacement therapy. We report a case of a pulmonary embolism in a patient with positive lupus anticoagulant who received estrogen replacement therapy. The patient was referred due to suddenly developed shortness of breath and echogenic mass densities in the right atrium on 2 dimensional echocardiography. The patient was markedly improved with intravenous urokinase and subsequent oral anticoagulant therapy. Related articles are also reviewed.

9.Clinical Experience of Cutaneous Squamous Cell Carcinoma Arising in Keratoacanthoma.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 2006;33(4):506-509
PURPOSE: The cutaneous squamous cell carcinoma is the second most common skin malignancy. It is noted that keratoacanthoma is difficult to differentiate from squamous cell carcinoma, clinically or historically. It is still a hypothetical question whether keratoacanthoma is a pseudomalignancy or a form of squamous cell carcinoma. METHODS: We report the case of squamous cell carcinoma around left ala of nose in a 64-year-old female patient. Through an incisional biopsy, the mass was found to be keratoacanthoma in the pathologic report. An excisional biopsy was performed. RESULTS: Pathologic report notified that it was found well-differentiated squamous cell carcinoma arising in keratoacanthoma with focal involvement of deep resection margin. Wide excision was made with 0.5-1.5cm margin and immediate reconstruction was performed. CONCLUSION: The relationship between keratoacanthoma and squamous cell carcinoma has been debated in the treatment. It is still controversial whether to excise it or not. We concluded that kerathoacanthoma must be removed completely.

10.Cause of Metatarsalgia.
Journal of Korean Foot and Ankle Society 2017;21(3):79-82
Metatarsalgia is one of the most common causes of patients complaining of pain in their feet. This pain is the plantar forefoot, including the second to fourth metatarsal heads and arises from either mechanical or iatrogenic causes. On the other hand, it is frequently accompanied by a deformity of the toes as well as of the first and fifth rays. The pain has a variety of causes, and sometimes the cause is difficult to distinguish. The variability of possible causative factors necessitates an individualized approach to treatment. To determine these causes, this paper presents an overview of the gait mechanics, plantar pressure, and the classification according to the etiology.
