Osteochondral autografts have recently become popular to treat articular cartilage defects, and they are used for unstable osteochondritis dissecans lesions as a means of biological fixation.To evaluate the clinical results osteochondral autograft transfer elbow.Case series; Level evidence, 4.Osteochondral was performed on 18 baseball players (mean age, 13.6 years) with elbow. These included 9 that were grade 3 (separated but in situ) 4 (displaced fragment defect) based magnetic resonance...
Comprehensive injury-prevention training (plyometric, agility, balance, and core-stability exercises) has been shown to decrease sport-related injury. The relationship between trunk control injury emphasized; however, the isolated effects of core-muscle are unclear.To investigate effect a simple 8-week core-muscle-training program on neuromuscular lower limb during jump landing single-legged squatting.Controlled laboratory study.Laboratory.Seventeen female collegiate basketball players were...
Functional evaluation assays using human induced pluripotent stem cell (hiPSC)-derived neurons can predict the convulsion toxicity of new drugs and neurological effects antiepileptic drugs. However, differences in responsiveness depending on convulsant type drugs, an index capable comparing vitro responses with vivo are not well known. We observed difference synchronized burst patterns epileptiform activities by pentylentetrazole (PTZ) 4-aminopryridine (4-AP) different action mechanisms...
A high incidence of anterior cruciate ligament (ACL) injuries related to sports activities has been reported; however, the injury situation ACL in badminton not elucidated. This study investigated mechanism using a questionnaire.Information on was gathered from interviews with six male and 15 female players who received non-contact playing underwent reconstruction.The most common (10 21 injuries) single-leg landing after overhead stroke. Nine 10 had injured knee opposite racket-hand side....
Sleep disturbances frequently accompany chronic pain from osteoarthritis (OA). Effective management of sleep may require successful treatment pain, a key factor in the clinical evaluation knee OA. However, relationship between severity OA and quality is unclear. Our purpose was to correlate prevalence nocturnal with different levels determine its influence on quality.Subjects included 1,214 local volunteers mean ± SD age 58.1 13.0 years. The existence were determined by Kellgren/Lawrence...
Background: There is controversy as to whether double-bundle anterior cruciate ligament (ACL) reconstruction with hamstring tendon graft (DB-HT) or single-bundle ACL patellar (SB-PT) obtains the best clinical outcomes. Purpose: To compare short-term outcomes of DB-HT those rectangular-tunnel SB-PT (RTSB-PT) at 2-year follow-up and identify factors that affect subjective knee functional score. Study Design: Randomized controlled trial. Level evidence, 1. Methods: Sixty-three male patients...
The locomotive syndrome risk test was developed to quantify the decrease in mobility among adults, which could eventually lead disability. purpose of this study establish reference values for adults and investigate influence age sex.We analyzed 8681 independent community dwellers (3607 men, 5074 women). Data pertaining (the two-step test, stand-up 25-question geriatric function scale [GLFS-25]) scores were collected from seven administrative areas Japan.The three generated all gradually...
Objective To compare findings of radiography, scintigraphy, and magnetic resonance imaging (MRI) in stress injuries bone evaluate changes these with time correlated clinical symptoms. Design Prospective study. Setting A primary care hospital outpatient orthopedic clinic. Patients All 31 patients who visited our clinic from July 1996 to June 2000. Intervention Radiography, MRI, examinations were performed on the same day or at least within 1 week eachother, compared. If symptoms injury...
Seventy-five patients underwent unilateral anterior cruciate ligament reconstruction with an ipsilateral bone-patellar tendon-bone autograft at our institution. The graft was harvested using a two-transverse-incision technique, and patellar tibial bony defects were repaired cored bone grafts collected by reaming the femoral socket or tunnel. We evaluated incidence of knee pain, donor site tenderness, sensory disturbance after use these procedures. also analyzed correlation between pain age,...
Several laboratory studies have pointed out a potential risk of femoral tunnel misplacement in anterior cruciate ligament reconstruction with transtibial technique. The malposition away from the anatomic attachment may result increased postoperative knee laxity double-bundle reconstruction.This study was conducted to evaluate and tibial positions reconstruction, determine relationship between results examinations.Case series; Level evidence, 4.Fifty-three 71 patients who underwent 2004 2005...
Radiographic findings may provide clues to the underlying cause of neck symptoms. However, these associations remain controversial. This study investigates association between roentgenographic cervical spine and symptoms in a Japanese community population.A total 762 volunteers participated this study. Sagittal radiographs were taken questionnaire about presence visual analog scale (VAS) for pain or stiff shoulder was completed. The sagittal alignment (C2-C7) degenerative index measured from...
Serum hyaluronic acid (sHA) is a serum biomarker for knee osteoarthritis (OA). Although sHA concentration elevated in patients with OA, the relationship between and disease progression remains unclear. We examined radiographic of OA cohort individuals followed 5 years.We prospectively enrolled 444 measured their concentrations at baseline. Anterior-posterior weight bearing radiographs were obtained baseline 5-year endpoint. Osteoarthritic changes classified according to Kellgren-Lawrence...
abstract The purpose of this study was to assess double-bundle anterior cruciate ligament (ACL) reconstruction, which reproduces the anteromedial bundle and posterolateral bundle, using a navigation system. In 32 patients, anteroposterior (AP) displacement rotation tibia were measured before reconstruction after fixation, ACL (in bundles fixation). has an important role in extension position, whereas restricts AP from flexion. significantly improved compared or fixation. Although traditional...
In situ fixation of unstable lesions osteochondral dissecans the knees with cylindrical autograft transplantation has been reported to provide excellent results healing fragment.To evaluate clinical and magnetic resonance imaging findings treated in fragments transplantation.Case series; Level evidence, 4.Twelve (12 patients; mean age, 16.0 years) were autogenous plugs. The lesion size was 2.4 cm(2) (range, 1.0-4.9 cm(2)). located on medial femoral condyle 10 patients lateral 2 patients....
