Background The purpose of this study was to evaluate the influence of posterior medial corner (PMC) injuries on clinical outcome and second-look arthroscopic findings after anterior cruciate ligament (ACL) reconstruction. Methods Seventy-eight consecutive patients underwent a second-look arthroscopic surgery after ACL reconstruction and magnetic resonance imaging (MRI) examination of the PMC. The patients were divided into a PMC intact group (n = 42) and a PMC injured group (n = 36). The stability and clinical outcomes were evaluated using the Lachman test, pivot-shift test, a KT-2000 arthrometer, and the Lysholm knee scoring scale. Graft tension and synovial coverage were evaluated in second-look arthroscopy. Results The clinical function showed no significant differences regarding PMC injury. Although the graft tendon tension revealed no significant differences (p = 0.141), the second-look arthroscopic findings indicated that the PMC intact group showed better synovial coverage compared to the PMC injured group (p = 0.012). Conclusion Patients who injured the PMC had poor synovial coverage as assessed by second-look arthroscopic findings after transtibial ACL reconstruction, even though clinical outcomes and stability showed no significant differences.

BACKGROUND The purpose of this study was to evaluate the influence of anterolateral ligament (ALL) injuries on stability and second-look arthroscopic findings after anterior cruciate ligament (ACL) reconstruction. METHODS One-hundred and nineteen consecutive patients underwent a second-look arthroscopic surgery after ACL reconstruction and magnetic resonance imaging (MRI) examination of the ALL. The patients were divided into an ALL intact group (n = 39) and ALL injured group (n = 80). The ALL injuries were divided according to the three anatomical parts of the ALL (femoral, meniscal, and tibial) using MRI evaluation. Stability and clinical results were evaluated using the Lachman test, pivot-shift test, KT-2000 arthrometer, and Lysholm score. On second-look arthroscopy, graft tension and synovial coverage were evaluated. RESULTS The clinical evaluation revealed no significant differences in ALL injury. Although the synovial coverages showed no significant difference (P = 0.113), the second-look arthroscopic findings indicated that tension was statistically significantly dependent on the ALL injury (P

Traumatic hip joint dislocations account for 2-5% of total joint dislocations. Bilater al asymmetric hip joint dislocation with anteriorly and posteriorly dislocation is an even more rare case because it was according to G. Loupasis reported in 11 cases only since 1879. We want to report 2 cases of bilateral asymmetric hip joint dislocation with unilateral acatabulum fracture which happened in our hospital. Bilateral asymmetric dislocation of hip joint accompanied by unilateral fracture of acetabulum is a very rare case so statistical verification cannot be done. However, close examinations are required at early treatment and follow-up because the patterns of dislocation and fracture of hip joint are variable and an orthopedic emergent condition and several complications may occur at both hip joints.

PURPOSE: The purpose of our study was to assess effect of posteromedial corner(PMC) injury on clinical outcomes and second-look arthroscopic findings after posterior cruciate ligament(PCL) reconstruction using Achilles tendon allograft. METHODS: A total of 51 patients who underwent arthroscopic PCL reconstruction for PCL rupture and second-look arthroscopy were retrospectively enrolled in our study from 2009 to 2019. The subjects were divided into two groups: PMC intact group included 31 patients; and PMC injured group included 18 patients. At least 1 years follow-up, clinical outcomes and arthroscopic findings including synovial coverage, tension were evaluated. RESULTS: Arthroscopic findings including the synovial coverages, tension showed significantly better at PMC intact group. (p

IntroductionAt present, information about clinical efficacy and adverse events of controlled release (CR) form of pelubiprofen, a prodrug of 2-arylopropionic acid with relatively selective effects on cyclooxygenase-2 activity, remains scarce. In this study, we sought to determine non-inferiority of pelubiprofen CR 90 mg/day compared to aceclofenac 200 mg/day regarding clinical efficacy and adverse events after a 4-week course of medication in the patients with symptomatic knee osteoarthritis.Materials and methodsA total of 191 patients were randomly assigned to take either pelubiprofen CR 90 mg (n = 95) or aceclofenac 200 mg (n = 96). The primary outcome variable was non-inferiority of pain reduction between baseline and week 4 when assessed using a 100 mm pain visual analogue scale (VAS). Pelubiprofen was considered non-inferior to aceclofenac if the upper limit of the one-sided 97.5% confidence interval for the difference in terms of pain VAS was above 15 mm (the average change of pain VAS in the pelubiprofen group-pain VAS reduction in the aceclofenac group). Secondary outcome variables were the changes in 100 mm pain VAS at week 2 versus baseline, K-Western Ontario, and McMaster University Arthritis Index (K-WOMAC) changes at weeks 2 and 4 as compared to baseline, patient global assessment at weeks 2 and 4. The frequency and amount of rescue medicine usage at weeks 2 and 4 were also evaluated as the secondary outcome variable. For safety analysis, adverse events, clinical laboratory tests, vital signs, and physical examinations were assessed and conducted at each follow-up visit.ResultsAt week 4, the pain VAS values were significantly reduced in both groups receiving either pelubiprofen CR 90 mg or aceclofenac 200 mg as compared to the baseline. However, the pelubiprofen group and the aceclofenac group respectively showed the pain VAS changes of -22 and -21.9 in the pre-protocol set and -20.8 and -21.7 in the full analysis set, confirming non-inferiority. The pelubiprofen CR 90 mg showed a reduced incidence of adverse events compared to the aceclofenac 200 mg (p = 0.005).ConclusionsPelubiprofen CR 90 mg is as effective as aceclofenac 200 mg with reduced adverse events for the treatment of symptomatic knee osteoarthritis.

Backgroud Intertrochanteric fractures are one of the most common fractures in the elderly, especially those having osteoporosis. Stable intertrochanteric fractures may be fixed with implants including the dynamic hip screw and proximal femoral nail antirotation; however, this method is difficult to apply to unstable fractures. Bipolar hemiarthroplasty can be applied to unstable fractures and it prevents complications by facilitating early ambulation in the elderly. Many studies reported on how to fix the greater trochanter in unstable fractures during arthroplasty. We suggest that suture fixation alone can be a useful, effective, and affordable method. Methods We retrospectively enrolled 294 patients who underwent hemiarthroplasty for an unstable intertrochanteric fracture, and 225 patients were included in this study after excluding 69 patients who had not been available for follow-up until 1 year after surgery or died. The patients were divided into suture fixation and wiring fixation groups. Relationships of operation time, estimated blood loss, tip-to-stem distance, union rate, and physical performance in the groups of suture fixation and wiring were analyzed respectively. Results Changes in the tip-to-stem distance between the initial assessment at 1 year after surgery were statistically significantly different between the suture fixation group and wiring group (p < 0.001). There was no significant difference in change of the Koval score between the suture fixation and wiring groups (p = 0.362). The operation time and estimated intraoperative blood loss were statistically significantly lower in the suture group than in the wiring group (p < 0.001). There was no significant difference in the union rate between the groups (p = 0.470). Conclusions Compared to tension-band wiring, the suture fixation technique demonstrated an effective fixing force. In addition to the clinical results, it had an advantage of preventing complications due to shortening of the operation time and estimated intraoperative blood loss. Suture fixation of the greater trochanter is recommended for elderly patients with unstable intertrochanteric fractures.

Purpose The aim of this study was to identify the effectiveness of C-arm fluoroscope in unicompartmental knee replacement arthroplasty through the clinical and radiologic results. Materials and methods We investigated the 33 cases of unicompartmental knee replacement arthroplasty in 31 patients who diagnosed degenerative arthritis of knee between February 2011 and March 2014. We divided 2 groups, one is 15 cases using C-arm fluoroscope during operation (group A), the other is 18 cases not using that (group B). We measured femoro-tibial angle (FTA), medial proximal tibial angle (MPTA), posterior tibial slope angle (PTSA), femoral component coronal rotation angle (FCRA) by simple X-ray. We evaluated femur and tibia varus/valgus mismatch and posterior slope mismatch by above parameters after operation. And also we evaluated clinically by knee and functional score. Results In group A, FTA average changes from −0.6° to 6.1°, MPTA changes from 84.5° to 87.6°, PTSA changes from 6.2° to 5.2° through operation. In group B, FTA changes from −0.4° to 5.8°, MPTA changes from 84.7° to 87.1°, PTSA changes from 6.3° to 5.5°, and FCRA is 0.6° in A group, 0.4° in B group after operation. The tibial varus/valgus mismatch cases after operation (nl.:87 ± 3°) was 1 in group A, 5 in group B. Post. slope mismatch cases after operation (nl.:7 ± 3°) was 1 in group A, 1 in group 31 B. All cases in both A and B group were not included in femoral varus/valgus mismatch (nl.:0 ± 3°) after operation. In group A, Knee score improved from 56.3 to 90.7, Functional score from 54.3 to 86.9 through operation. In group B, Knee score improved from 54.9 to 89.8, Functional score from 52.8 to 84.6. Conclusion There was no statistically significant difference in radiologic and clinical results between group A and B, but the number of tibial varus/valgus mismatch case were fewer in fluoroscope guided group. Sowe consider that thefluoroscope is helpful for tibial cuttingin unicompartmental knee replacement arthroplasty.

Purpose Although allogeneic blood transfusion is the most common method of transfusion in total knee arthroplasty (TKA), there are reports showing significant decrease in the amount of allogeneic transfusion and incidence of side effects after combined use of autologous transfusion. The purpose of this study is to investigate the efficacy of using an autologous transfusion device in TKA. Materials and Methods Patients who underwent TKA at our institution from January 2003 to January 2014 were divided into two groups: group A (n=127) who received allogeneic transfusion only in TKA and group B (n=118) who received autologous transfusion via an autologous transfusion device and allogeneic transfusion. In both groups, the patients were transfused when the hemoglobin level was below 9 g/dL. In group B, blood collected by the autologous transfusion device was transfused only once after surgery. The total blood loss volume, total transfusion volume, and the presence of side effects were assessed based on medical records. Results Group A received 294.6 mL more allogeneic transfusion than group B (p

Due to a big difference of temperatures between the inside and outside and a high level of hydration heat on the core, some thermal stress is generated in mass Concrete. In turn, it causes the expansion of the concrete members and some cracks of the concrete joints that become the factors threatening the soundness of a concrete structure. Due to the reason, various kinds of low-heat concrete are being developed in domestic and foreign countries. In this study, some urea for industrial use which is used in microorganism cultivation agents, etc., is applied as a concrete mixing material in order to suppress the hydration heat of mass concrete. This is intended to lower down some levels of hydration heat and drying shrinkage of mass concrete. 21 kinds of concrete mixtures in total were designed at 3 kinds of W/B ratios, that is, 45, 50 and 55%. Thus, the dynamic characteristics, durability and hydration heat properties of urea-mixed concrete were verified through some experiments and the optimum mixing design was suggested. As the results of this study, the compressive strength of urea-mixed concrete at the age of 3 days decreased by 40% compared to that of plain concrete, but it showed the tendency recovering up to 95% at maximum at the age of 56days. On the other hand, the maximum temperature of urea-mixed concrete decreased down to at maximum thanks to the hydration heat compared with that of plain concrete and the point of time reaching the highest temperature of the urea-mixed concrete was delayed by 33.9 hours at maximum compared with that of plain concrete. In addition, it resulted that the length change rate of urea-mixed concrete decreased down to 56% at maximum thanks to the expansion characteristics of .

Concrete filled tube (CFT) columns, which consist of a steel tube filled with concrete, combine the benefits of the two materials. The steel tube provides a confining pressure to the concrete, while the local buckling of steel plate can be prevented by the concrete core. CFT columns also have a high fire resistance due to the heat storage effect of concrete under fire. For this reason, it is possible to develop CFT columns without fire protection measures. CFT columns without fire protection have many advantages, including quality control, cost reduction, better space efficiency and a shorter construction period. Due to these advantages, studies on the development of CFT columns without fire protection measures have been performed. However, CFT columns lose their bearing capacity under fire because the steel tube is exposed to the outside. As a result, the structure is collapsed, causing significant damage. In this research, we made a CFT column using high strength concrete (100 MPa) and high strength steel (800 MPa). We use steel fiber and nylon fiber with concrete to provide fire resistance. We perform the fresh concrete experiment and investigate the fire resistance of the CFT column (□ 400×400×15×3000 mm) under loading. To investigate the effect of steel fiber on increasing fire resistance, we compare the fire resistance time according to the steel fiber. Through the test, it was found that the CFT specimen with steel fiber had better fire resistance performance than other cases.

In the past, recycled aggregate was used very limitedly in low value-added areas such as the base layer of roads. However, in response to the shortage of natural aggregate, high consciousness of resource saving and changed idea on environment, the quality of recycled aggregate has been improved considerably, and the percentage of recycled construction waste is increasing every year compared to simple landfill or incineration. Recently the Act on the Promotion of Construction Waste Recycling was enacted on December 2003 for the efficient use of recycled aggregate, and the Standards for the Quality of Recycled Aggregate for Concrete (Proposal) were announced in order to use and manage recycled aggregate according to quality. According to the Standards for the Quality of Recycled Aggregate for Concrete (Proposal), it is recommended to substitute recycled coarse aggregate and fine aggregate below 30% each. However, compared to the trend of recycling, the recycling rate of aggregate is still quite low. It is because of low performance of recycled aggregate, users` lack of understanding, etc. These problems basically come from the decrease of strength of recycled concrete resulting from the use of recycled aggregate, and recycled aggregate is still considered not reliable because there have been not many cases of actual application. If the basic problem of strength decrease is solved and data on recycled aggregate is provided through actual field placing, we may maximize the use of recycled aggregate. Thus, in order to maximize the use of recycled aggregate that satisfy the recycled aggregate quality standards, the present study made a mock-up similar to real structures, evaluated its performance and examined the field applicability of recycled aggregate concrete.

Most concrete is recently made of an aggregate which is properly absorbed, and carried in it in order to do capability at every fields. We have been close to demand new rapability of high flowing and enduring for specific concretes. That is difficult to cope with claiming the efficiency on deterioration from lack of a high quality aggregate. Therefore, For solving the problems we apply to a packing method for using dried materials. That is to say that it is a kind of making into an instant. In this study. There is a purpose to present fundamental data, comparing and analyzing a phenomenon of aggregate`s absorption following the rate of adding water, for using existing materials.

The range of motion after operation were increased in two groups. Excellent to good results were obtained 93％ and 95％ patients had pain relief and satisfied function. Conclusion : Arthroscopic subacromial decompression and arthroscopic rotator cuff repair showed good results for both of (ult-thickness and partial thickness rotator cuff tear patients in pain relief and improving the function.

Purpose The purpose of this study was to assess the recurrence rate and postoperative residual pain rate after arthroscopic excision of dorsal wrist ganglia and the risk factors for recurrence and residual pain. Methods A total of 115 wrists (111 patients: 57 men, 54 women; average age 34 years; range, 9 to 72 years) treated with arthroscopic excision for wrist dorsal ganglia between April 2005 and December 2009 were enrolled. The follow-up averaged 32 months (range, 12 to 67 months). Demographic data and operative details, including the presence of a ganglion stalk, were retrospectively reviewed and tested against recurrence and residual pain at final follow-up. Results The recurrence rate of dorsal wrist ganglia after arthroscopic excision was 11% (13 of 115 wrists). Recurrence was on the dominant side in 12 of 13 (91%) patients, which was the most important risk factor for recurrence (odds ratio [OR], 8.0; 95% confidence interval [CI], 0.94 to 68.49), followed by female sex (OR, 4.9; 95% CI, 0.84 to 28.39) and age 24 years or younger (OR, 3.1; 95% CI, 0.75 to 12.74). Twenty-seven wrists (23%) had postoperative residual pain at final follow-up. The results of logistic regression showed that pain before surgery was the most important risk factor for residual pain after surgery (OR, 4.9; 95% CI, 1.36 to 18.3), followed by female sex (OR, 3.2; 95% CI, 1.22 to 8.53). Conclusions Dominant side, female sex, and age of 24 years or younger are considered to be the most influential risk factors for recurrence after arthroscopic excision of dorsal wrist ganglia. However, the presence or absence of the cyst stalk was not a significant factor for recurrence. Female patients who have preoperative pain around the dorsal wrist ganglia were most likely to experience residual pain after surgery. Level of Evidence Level IV, therapeutic case series.

Popliteal artery entrapment syndrome can result from abnormal branching patterns of the popliteal artery or the anatomically abnormal placement of nearby muscles and tendons leading to a sustained compression of the popliteal artery. This compression leads to chronic capillary damage and early arteriosclerosis and embolism that can lead to distal ischemia. Thus early treatment is required to prevent harm to the lower limb. This is a rare congenital disease that mostly affects young adults, usually presenting with intermittent claudication of the leg, coldness and edema. A case where a 16-year-old female presented with pain and coldness in the lower right limb that started 1 year ago will be discussed. In this case, magnetic resonance imaging and arterial angiography lead to a diagnosis of popliteal artery entrapment resulting from an abnormal origin of the medial head of Gastrocnemius.

Purpose: The purpose of this study was to analyze the influence of posterior tibial slope on stability in clinical and second-look arthroscopic evaluation after anterior cruciate ligament (ACL) reconstruction. Materials and Methods: From 2000 to 2011, 124 patients who underwent ACL reconstruction using an allogaft were enrolled in this study. A posterior tibial slope between 0 and 4 was found in 28 patients (group A), between 5 and 9 in 64 patients (group B), and greater than 10 in 32 patients (group C). We evaluated stability using the Lachman test and a KT-2000 arthrometer. In second-look arthroscopy, grafted tendons were evaluated based on the tension, rupture, and synovial coverage. Results: In clinical evaluation for stability, mean KT-2000 arthrometer and Lachman test at last follow-up showed no statistically significant differences depending on posterior tibial slope. Second-look arthroscopic findings showed no statistically significant difference between groups A and B (p=0.91). However, statistically significant relations were observed between groups A and C (p=0.03), and between groups B and C (p=0.02). Conclusion: The results of this study suggest that patients who underwent ACL reconstruction with higher posterior tibial slope (≥10) have more lax tension in second-look arthroscopy, but not in clinical stability tests.

Purpose: To provide information on the thickness of the patella in Korean adults and to provide a standard for the selection of a proper patella implant in total knee arthroplasty. Materials and Methods: From October 2002 to June 2004, the patellar thickness was measured by MRI in 165 knees. The mean age of the patients was 29 years (20-39 years). Patients with either patellar fractures or deformities were excluded. Of the knees included in this study, 54 knees had meniscal injuries, 53 had cruciate ligament injuries, 24 had knee contusions, and 17 had other disorders. The remaining 17 knees were normal. The measurements were taken in the axial and sagittal images of the MRI scans. The maximum distance in millimeter between the anterior cortex of the patella and the surface of the articular cartilage was measured to the first decimal place. The relationship between the patellar thickness and gender, weight and height was also analyzed. Results: The average patellar thickness on the axial image was 23.8 (SD 1.4) mm in males and 21.7 (SD 1.4) mm in females. The measurement estimated in the axial image was not significantly different from that in the sagittal image. The patellar thickness in males was significantly thicker than in females (p
