- A Quartet of Elastic Stable Intramedullary Nails for More Challenging Pediatric Femur Fractures. [Journal Article]
- JPJ Pediatr Orthop 2019; 39(1):e12-e17
- CONCLUSIONS: Treatment with a quartet of ESINs should be considered for skeletally immature children with length-unstable or metadiaphyseal femur fractures. In this series, all fractures achieved union without major complications or hardware failure. This modification to traditional elastic nailing techniques is an option for the surgeon to consider as an alternative to rigid intramedullary nailing, submuscular plating, or external fixation.
- Management of Long-Term Complications in the Setting of Lateral Meniscal Deficiency After Saucerization of a Discoid Lateral Meniscus in an Adolescent Patient: A Case Report and Review of the Literature. [Journal Article]
- JCJBJS Case Connect 2018 Dec 12
- CONCLUSIONS: New treatment paradigms following initial interventions for discoid menisci are discussed. Patients may benefit from longer follow-up after discoid meniscal surgery, and providers should consider joint-preserving techniques early in the setting of meniscal deficiency.
- Tourniquet application does not affect the periprosthetic bone cement penetration in total knee arthroplasty. [Journal Article]
- KSKnee Surg Sports Traumatol Arthrosc 2018 Dec 11
- CONCLUSIONS: Tourniquet application did not influence the bone cement penetration significantly. Even though the intraoperative blood loss was reduced, the total blood loss was not affected significantly by tourniquet use. There was a tendency of higher post-operative pain and opioid analgesic requirement in the tourniquet group.
- Clinical and radiologic outcomes of two patellar resection techniques during total knee arthroplasty: a prospective randomized controlled study. [Journal Article]
- IOInt Orthop 2018 Dec 11
- CONCLUSIONS: Cutting guide technique group did not yield lower incidence of anterior knee pain. More outliers of lateral patellar tilt were observed in the freehand technique group. Overall, all patients in both groups had identical results in terms of patellofemoral functional capacity, clinical outcomes, and other radiographic results.
- A case series of cementless revision total knee arthroplasty in patients with benzoyl peroxide allergy. [Journal Article]
- IOInt Orthop 2018 Dec 11
- CONCLUSIONS: The regression of complaints after replacement with cementless and nickel-free revision implants suggests allergic implant intolerance. Implantation of a cementless, hypoallergenic endoprosthesis might, therefore, be a surgical treatment strategy in patients with evidence of allergies.

Osgood-Schlatter disease is a painful condition, affecting the tibial tuberosity of physically active children with a painful bump that aggravates with repetitive impacts over the affected area during exercise, sports, or even usual daily activities. The condition is usually unilateral; however, bilateral presentation is not unlikely. In addition to clinical features, a unique radiological finding appears worthy in terms of accurate diagnosis. Moreover, ultrasonogram-based pathological changes could appear not only in the tibial tuberosity but also in the patellar tendon. In this study subject, I approached the condition with a high-frequency musculoskeletal ultrasonogram in order to add further information about the ailment in medical literature. The conservative approach was found effective to relieve the patient's problems.

Local infiltration analgesia (LIA) supports early mobilization after hip and knee arthroplasty. Inspired by this, we studied the effectiveness of wound infiltration with the long acting local anesthetic ropivacaine in an effort to decrease the need for postoperative opioids after osteosynthesis of extracapsular hip fracture.
- The Clinical Efficacy and Safety of Gumiganghwal-Tang in Knee Osteoarthritis: A Phase II Randomized Double Blind Placebo Controlled Study. [Journal Article]
- EBEvid Based Complement Alternat Med 2018; 2018:3165125
- CONCLUSIONS: Treatment with GMGHT resulted in significant improvement in pain, function, and global assessment, and it was generally safe and well tolerated in patients with OA.
- Pathological findings of late stent thrombosis after paclitaxel-eluting stent implantation for superficial femoral artery disease. [Journal Article]
- JCJ Cardiol Cases 2015; 11(2):39-41
- A 76-year-old man presented with right critical limb ischemia. An angiography revealed right SFA occlusion. Therefore, two paclitaxel-eluting stents (Zilver PTXs 6.0 mm × 120 mm stents; Cook Medical,...
A 76-year-old man presented with right critical limb ischemia. An angiography revealed right SFA occlusion. Therefore, two paclitaxel-eluting stents (Zilver PTXs 6.0 mm × 120 mm stents; Cook Medical, Bloomington, Indiana) were placed, which promoted good blood flow. Follow-up angiography at 6 months also showed no restenosis. However, 10 months later, the patient suddenly visited with acute-onset pain in the right leg. Computed tomography showed the acute occlusion at the stented SFA. Eventually, above-knee amputation was performed due to the poor general condition and progressive limb ischemia. As the pathological finding, heterogeneous neointima formation at the stented site was mainly found. Although neointimal layer consisting of smooth muscle cell (SMC) was partly observed, necrotic tissue was evident in the remaining portion. At the necrotic tissue site, the majority of the components of the material covered by the stent strut were fibrin deposits. The findings of regenerative endothelial cells were not observed at the luminal surface. Nuclei of medial SMCs were also lost between the arterial media and the stent strut. Late stent thrombosis after paclitaxel-eluting stenting for SFA lesion has not been sufficiently evaluated. Here, we report a case of late stent thrombosis with a review including pathological findings. <Learning objective: We reported that a 76-year-old man received paclitaxel-eluting stent for femoropopliteal disease. Ten months later, stent thrombosis was occurred and above-knee amputation was performed. As the pathological finding, heterogeneous neointima formation was mainly found and the regenerative endothelial cells were not observed. Our report suggested that delayed healing and uncovered strut caused by paclitaxel-exposure resulted in late stent thrombosis.>.

Infrapatellar fat pad has been implicated in knee osteoarthritis. We examined whether infrapatellar fat pad volume is associated with quantitative cartilage changes using magnetic resonance imaging T1ρ mapping. Fifty-eight knees of knee pain patients (19 men, 39 women, mean age 57.0 [range 29-85] years) who were conservatively managed and had >1 T1ρ mapping images taken over time were evaluated. We used 3 slices from the medial femoral and tibial cartilage; areas showing T1ρ values <130 ms and >50 ms were designated as having cartilage degeneration. Cases were categorized into three groups: Improvement, No Change, and Deterioration. Fat-suppressed T2-weighted sagittal magnetic resonance images were used for measuring infrapatellar fat pad volume. Percent change in infrapatellar fat pad volume was -5.01 ± 5.66%, -2.06 ± 4.92%, and 0.05 ± 6.09% in the Improvement (n = 22), No Change (n = 22), and Deterioration (n = 14) groups, respectively, demonstrating significantly reduced infrapatellar fat pad volume in the Improvement group (P < 0.05). Multivariate regression analyses revealed that the percent change in infrapatellar fat pad volume significantly affected T1ρ change category independent of age, sex, follow-up period, baseline infrapatellar fat pad volume, and Kellgren-Lawrence grade. Infrapatellar fat pad volume and obesity or body weight change showed no correlation. Infrapatellar fat pad volume was reduced in patients with improved quantitative cartilage assessment on magnetic resonance imaging T1 ρ mapping. This is the first study demonstrating associations between quantitative cartilage changes and infrapatellar fat pad morphological changes, suggesting a detrimental role of infrapatellar fat pad volume in articular cartilage degeneration.
