The most common complication of total ankle arthroplasty is skin problem including delayed wound healing, skin necrosis, and superficial wound infection. In the present study, we aimed to reduce the wound complications associated with total ankle arthroplasty using a curvilinear incision. We examined 5 patients with ankle osteoarthritis who underwent total ankle arthroplasty using a curvilinear incision from September 2012 to January 2013. Wound dehiscence was noted in 1 case, which was treated with a re-repair procedure at 13 days after the initial surgery. The use of a curvilinear incision in total ankle arthroplasty may reduce the associated wound complications.

Xanthoma is a relatively rare soft tissue lesion on the Achilles tendon and is usually associated with hyperlipidemia (lipid metabolism abnormality), mental retardation, cataract and atherosclerotic disease. We report on a case of normolipidemic bilateral Achilles tendon xanthoma without any notable cause. We herein describe the case where we achieved a satisfactory result by subtotal resection.

Popliteal artery compression rarely occurs after posterior cruciate ligament (PCL) reconstruction using the tibial inlay technique that allows for direct visualization of the surgical field. However, we experienced a popliteal artery compression after PCL reconstruction performed using the technique, which eventually required re-operation. Here, we report this rare case and discuss reasons of popliteal artery compression.

BACKGROUND: This study aimed to compare the effects of femoral nerve block and adductor canal block on postoperative pain, quadriceps strength, and walking ability after primary total knee arthroplasty. METHODS: Between November 2014 and February 2015, 60 patients underwent primary total knee arthroplasty. Thirty patients received femoral nerve block and the other 30 received adductor canal block for postoperative pain control. Before spinal anesthesia, the patients received nerve block via a catheter (20 mL 0.75% ropivacaine was administered initially, followed by intermittent bolus injection of 10 mL 0.2% ropivacaine every 6 hours for 3 days). The catheters were maintained in the exact location of nerve block in 24 patients in the femoral nerve block group and in 19 patients in the adductor canal block group. Data collection was carried out from these 43 patients. To evaluate postoperative pain control, the numerical rating scale scores at rest and 45° flexion of the knee were recorded. To evaluate quadriceps strength, manual muscle testing was performed. Walking ability was assessed using the Timed Up and Go test. We also evaluated analgesic consumption and complications of peripheral nerve block. RESULTS: No significant intergroup difference was observed in the numerical rating scale scores at rest and 45° flexion of the knee on postoperative days 1, 2, 3, and 7. The adductor canal block group had significantly greater quadriceps strength than did the femoral nerve block group, as assessed by manual muscle testing on postoperative days 1, 2, and 3. The 2 groups showed no difference in walking ability on postoperative day 1, but on postoperative days 2, 3, walking ability was significantly better in the adductor canal block group than in the femoral nerve block group. No significant intergroup difference was observed in analgesic consumption. CONCLUSIONS: The groups showed no difference in postoperative pain control. Adductor canal block was superior to femoral nerve block in preserving quadriceps strength and walking ability. However, adductor canal block was inferior to femoral nerve block in maintaining the exact location of the catheter.

PURPOSE: To evaluate the hemodynamic status of varicocele, 99m Tc-RBC venography was performed in 29 varicocele patients and 10 normal controls from January to July 1996. MATERIALS AND METHODS: The mean age of varicocele patients was 23 years old and of normal controls was 27 years old. Among 29 varicocele patients, 26 had varicocele in left side and 3 had in both side. In unilateral varicocele group. 2 cases had grade I, 8 cases had grade II and 16 cases had grade III varicocele. In bilateral varicocele group, all had grade III in le% side and grade II varicocele in right side. RESULTS: The mean+/-SD of left to right radionuclide uptake ratio in pampiniform plexus during resting and Valsalva maneuver state was 1.01 +/-0.04:1 and 1.05+/-0.05:1 in normal control, 1.05+/-0.02:1 and 1.10:1 in varicocle grade I, 1.21+/-0.19:1 and 1.21 +/-0.12:1 in varicocele glade II, 1.60+/-0.63:1 and 1.27+/-0.18:1 in varicocele grade III, 1 18+/-0.06:1 and 1.26 in bilateral varicocele. As varicocele grade be higher, the mean left to right radionuclide uptake ratio be larger during resting and Valsalva maneuver state. CONCLUSIONS: 99mTc-RBC venography can quantify the hemodynamic state of varicocele so we suggest that it is useful as a method of diagnosis and follow up in varicocele patient.

PURPOSE: The purpose of this study was to evaluate the clinical results of fixation of the unstable osteochondral dissecans (OCD) lesion with autologous osteochondral plugs. MATERIALS AND METHODS: This study was conducted in 19 patients who were relevant to the International Cartilage Repair Society 2, 3, or 4 who were treated with autologous osteochondral plugs and followed-up for more than 2 years from January 2004 to January 2012. Clinical evaluation was performed by comparing the preoperative and last follow-up scores of Lysholm score and subjective International Knee Documentation Committee (IKDC) score. RESULTS: All patients were male and the average age was 19.1 years. Of the 19 cases, there were 16 cases of medial femoral condyle lateral side lesion, 2 cases of lateral femoral condyle articular surface, and 1 case of femoral intercondylar notch lesions. The average size of the lesion was 5.68 mm2, and average use of osteochodral plugs were 4.3. Average follow-up period was 38 months. Preoperative Lysholm score, IKDC subjective score showed significant improvement. CONCLUSION: Fixation with autologous osteochondral plugs for unstable OCD uses the remnant tissues therefore conserving it, which is thought to be the positive aspect of this type of operation.

PURPOSE: The purpose of this study was to analyze patient factors including smoking, body mass index, correction angle, graft material, presence of lateral cortex fracture, and age for the effect on bone union after open-wedge high tibial osteotomy and the effect of graft material used for lateral cortex fractures. MATERIALS AND METHODS: This retrospective study was conducted on 54 patients and 58 cases with osteoarthritic change Kallgren-Lawrence grade 2 or less from May 2012 to June 2014. Average follow-up period was 22 months (14–38 months). The patients were divided into two groups according to patient related factors and graft materials (allograft, n=6; beta-tricalcium phosphate [β-TCP], n=6) used for lateral cortex fractures and were analyzed for the relationship with bone union after open-wedge high tibial osteotomy. Radiographic and clinic analyses were performed, and van Hemert grading was used for grading bone union at 6 weeks, 3 months, 6 months, and 1 year postoperatively. RESULTS: The non-smoking group and the group without lateral cortex fracture showed significantly higher bone union rates than the control group. No significant clinical or radiological difference was observed between the two groups in 12 cases and the allograft group showed significantly higher rates of union at 6 months and 1 year postoperatively according to the van Hemert grading. CONCLUSION: Smoking and the presence of a lateral cortex fracture is a risk factor for nonunion in medial open-wedge high tibial osteotomy. The use of allograft material rather than β-TCP for lateral cortex fractures is thought to result in better bone union.

PURPOSE: The purpose of this study was to investigate complications and radiologic and clinical outcomes of medial opening wedge high tibial osteotomy (MOWHTO) using a locking plate. MATERIALS AND METHODS: This study reviewed 167 patients who were treated with MOWHTO using a locking plate from May 2012 to June 2014. Patients without complications were classified into group 1 and those with complications into group 2. Medical records, operative notes, and radiographs were retrospectively reviewed to identify complications. Clinically, Oxford Knee score and Knee Injury and Osteoarthritis Outcome score (KOOS) were evaluated. RESULTS: Overall, complications were observed in 49 patients (29.3%). Minor complications included lateral cortex fracture (15.6%), neuropathy (3.6%), correction loss (2.4%), hematoma (2.4%), delayed union (2.4%), delayed wound healing (2.4%), postoperative stiffness (1.2%), hardware irritation (1.2%), tendinitis (1.2%), and hardware failure without associated symptoms (0.6%). Major complications included hardware failure with associated symptoms (0.6%), deep infection (0.6%), and nonunion (0.6%). At the first-year follow-up, there were no significant differences in radiologic measurements between groups 1 and 2. There were no significant differences in knee scores except for the KOOS pain score. CONCLUSIONS: Our data showed that almost all complications of the treatment were minor and the patients recovered without any problems. Most complications did not have a significant impact on radiologic and clinical outcomes.

PURPOSE: We compared adductor canal block (ACB) alone and a combination of ACB and sciatic nerve block (SNB) to control early postoperative pain after total knee arthroplasty. MATERIALS AND METHODS: One hundred patients received continuous ACB alone (group A), and another 100 patients received continuous ACB and single popliteal SNB (group B). Pain was evaluated at rest and 45° knee flexion using the numeric rating scale (NRS). The number of times the patient pressed the intravenous patient-controlled analgesia (PCA) button, total PCA volume infused, and the total dosage of additional analgesics were evaluated. We also investigated complications associated with each pain control technique. RESULTS: The NRS score on postoperative day 1 was significantly lower in group B than in group A. The number of times patients pressed the PCA button on postoperative day 1 and the total infused volume were significantly lower in group B than in group A. Thirty-five (35%) patients in group B developed foot drop immediately after surgery; but they all fully recovered on postoperative day 1. CONCLUSIONS: SNB can be effective for management of early postoperative pain that persists even after ACB. Further research is needed to determine the proper dosage and technique for reducing the incidence of foot drop.

The inheritance of ABO blood type group is actually determined by triple allelic gene, A, B and O. Transmission of blood group AB by a single chromosome, instead of by two separate chromosomes, was reported and called cis AB. The anesthesiologists, who meet many cases of the transfusions, may anesthetize cis AB patients for surgery. Recently the authors have experienced one case of patient with cis AB blood type undergoing emergency craniotomy and removal of hematoma. We transfused the patient with Rh+O packed red blood cell without any significant transfusion reactions.
