Background: Because grafts are made in 0.5-mm increments clinically for anterior cruciate ligament (ACL) reconstruction, it is important to clarify how the failure rate decreases as diameter increases. Moreover, know whether even a slight increase graft risk of failure. Hypothesis: The significantly with each hamstring diameter. Study Design: Meta-analysis; Level evidence, 4. Methods: systematic review and meta-analysis have estimated diameter-specific ACL reconstruction using autologous...
A 71-year-oldman was found to have chronic lymphocytic leukemia (CLL) and diffuse large cell lymphoma (DLC) simultaneously diagnosed as Richter's syndrome. The CLL had mu lambda surface immunoglobulin (sIg) whereas the DLC kappa sIg. However, (Ig) gene rearrangement marker analysis demonstrated that both identical patterns of Ig heavy chain (IgH) markers CD5+, CD19+, CD20+. These facts imply in this case two malignancies are single clonal origin initially, different sIg do not, therefore,...
Abstract Purpose Favorable clinical results have been reported following high tibial osteotomy (HTO) for medial meniscus posterior root tear (MMPRT) in knees with varus alignment. However, the effect on preoperative neutral alignment of knee is not known. This study sought to evaluate outcomes open-wedge HTO MMPRT Methods We retrospectively reviewed 119 HTOs and analyzed 22 MMPRT. The were divided according hip-knee-ankle angle into a moderate group (≤4° alignment) (> 4° alignment). Knee...
A 13-year-old girl presented with general fatigue, back pain, anemia, hyperimmunoglobulinemia, and a mediastinal mass on chest radiograph. was surgically removed, its histologic examination determined the diagnosis of giant lymph node hyperplasia (Castleman's disease). With removal hyperplastic node, clinical symptoms soon disappeared abnormal laboratory findings were markedly improved within 1 month: serum IgG levels decreased from 4350 mg/dl to 1829 mg/dl. Immunostaining sections revealed...
Prolongation of operation time due to registration and pin insertion has been reported with robotic-assisted total knee arthroplasty (RATKA), there concern about an increase in the postoperative incidence deep vein thrombosis (DVT). In this study, we compared DVT after RATKA that conventional manual TKA (mTKA).This consecutive retrospective series included 141 knees underwent primary using Journey II system. The CORI robot was used. There were 60 RATKAs 81 mTKAs. Doppler ultrasound performed...
The purpose of this study was to clarify the association between clinical outcomes and flexion joint gap following rotating concave-convex (Vanguard ROCC) total knee arthroplasty (TKA).This consecutive retrospective series included 55 knees that underwent ROCC TKA. All surgical procedures were performed using a spacer-based gap-balancing technique. To evaluate medial lateral gaps, axial radiographs distal femur obtained epicondylar view with distraction force lower leg at 6 months...
Abstract Purpose The effect of open‐wedge high tibial osteotomy (OWHTO) on the preoperative neutral alignment knee is unknown. purpose this study was to clarify clinical outcome OWHTO with alignment, defined as within 4 degrees varus. Methods This retrospective included 72 knees varus that underwent medial OWHTO. were divided according hip‐knee‐ankle angle into a group (≤ 4° alignment) and (> alignment). Knee Injury Osteoarthritis Outcome Score (KOOS) Forgotten Joint Score‐12 (FJS‐12)...
Serum and early-morning urinary levels of estrone sulfate during the menstrual cycle were measured by a direct radioimmunoassay without hydrolysis. These high showed prominent peaks [serum, 2.67 ± 0.37 ng/ml (mean SE); urine, 5.82 2.3 µg/l] around day preovulatory estradiol-17β peak, increased again luteal phase. Following intravenous injection sulfate, serum measured. The conversion to and/or was very small their transit in general circulation.
Abstract Background The incidence and characteristics of deep vein thrombosis (DVT) following total knee arthroplasty (TKA) without pharmacologic prophylaxis have not been fully investigated. This study aimed to determine whether there are any differences in the incidence, location, DVT TKA with prophylaxis. Methods A 156 knees were retrospectively evaluated for by duplex ultrasound on postoperative day 7, after excluding 60 from 216 consecutive because antiplatelet or anticoagulant use...
One of the most common types coronal plane alignment knee (CPAK) is type I, which characterised by varus and apex distal joint line obliquity. The purpose this study was to evaluate association changes in arithmetic hip-knee-ankle angle (aHKA) with both postoperative laxity patient-reported outcome measures (PROMs) patients CPAK I following mechanical (MA) total arthroplasty (TKA).
A T-cell malignancy developed in a 64-year-old man with recurrent B-cell lymphoma after one and half years of remission. Immunophenotypic DNA analyses confirmed clonality cell lineage both lymphoid malignancies. Sequential development B- malignancies this patient may be an example biclonal or treatment-related secondary lymphoma. However, another possibility would the existence transformed stem that underwent intraclonal conversion from to lines.
Abstract Background Some patients complain of noise after total knee arthroplasty (TKA). Controversy still exists on how the affects clinical outcomes, including joint awareness, TKA. The Forgotten Joint Score—12 (FJS-12) measures outcomes focusing awareness surgery. Knee Society Scoring System—2011 (KSS-2011) includes questionnaires for satisfaction, expectation, and functional activities. aim this study is to clarify relationship among FJS-12, KSS-2011, noise. Furthermore, between FJS-12...
Abstract There is an essential demand for developing biocompatible grafts knee anterior cruciate ligament reconstruction (ACLR). This study investigated cell infiltration into decellularized bovine tendon xenografts using a rat ACLR model. Twelve-week-old Sprague–Dawley rats were used. At weeks 1, 2, 4, 8, 16, 26, and 52 (each period, n = 6) after ACLR, receiving (group D, 42) or autologous A, as underwent peritibial bone tunnel mineral density (BMD), histological, immunohistological...
Orthopaedic surgery requires grafts with sufficient mechanical strength. For this purpose, decellularized tissue is an available option that lacks the complications of autologous tissue. However, it not widely used in orthopaedic surgeries. This study investigated clinical trials use surgery. Using ClinicalTrials.gov (CTG) and International Clinical Trials Registry Platform (ICTRP) databases, we comprehensively surveyed surgeries registered before 1 September 2022. We evaluated results,...
Abstract Background Patellofemoral overstuffing after total knee arthroplasty (TKA) can cause limited range of motion and anterior pain. This study compared prominence femoral components among different prothesis designs in surgical simulation models utilizing the reference (AR) posterior (PR) techniques. Methods Surgical simulations were performed using on a three-dimensional planning system preoperative computed tomography data consecutive 30 patients with osteoarthritis scheduled to...
A case of malignant ependymoma with extracranial metastases is reported. 59-year-old male was admitted to our hospital vomiting and ataxia. Following computed tomographic (CT) scanning indicating a ring-like enhanced mass in the cerebellum, tumor subtotally removed December, 1985. Histological diagnosis ependymoma. second operation performed February, 1987, due recurrence fourth ventricle. Postoperative radiation therapy at total dose 7780 rads given over 2 years. Eleven months after...
This report presents a case of deep peroneal nerve palsy caused by an injury during drilling for distal locking screws T-shaped plate used osteosynthesis medial open-wedge high tibial osteotomy. A cadaveric simulation study reproduced the risk surgery.
Abstract Background Although favorable long-term survival of Oxford unicompartmental knee arthroplasty (UKA) has been reported regardless postoperative varus alignment, the effect degree alignment on patient-reported outcome measures (PROMs) remains unclear. Furthermore, Forgotten Joint Score-12 (FJS-12), which a low ceiling effect, may be useful for such assessment. The objective this study was to evaluate short-term clinical outcomes after UKA in knees with greater preoperative focusing...
