CONTEXT: Patellar tendinopathy is prevalent in physically active populations and it affects their quality of living, performance of activity, and may contribute to the early cessation of their athletic careers. A number of previous studies have identified contributing factors for patellar tendinopathy however their contributions to self-reported dysfunction remain unclear. OBJECTIVE: The purpose of this investigation was to determine if strength, flexibility, and various lower extremity static alignments contributed to self-reported function and influence the severity of patellar tendinopathy...

The transforaminal lumbar interbody fusion (TLIF) is used for the treatment of back and leg pain secondary to spinal stenosis, degenerative disc disease, and spondylolisthesis. Minimally invasive surgery (MIS) is associated with less estimated blood loss (EBL), decreased length of stay, lower infection rates, and similar outcomes compared to the traditional TLIF. Fluoroscopy time has been reported with MIS-TLIF, but there are limited data on specific radiation dosages. We performed a retrospective analysis of a prospectively acquired cohort of patients undergoing MIS-TLIF...

BACKGROUND: We aimed to compare the effect of tourniquet use or lack of it on recovery following uncomplicated primary total knee arthroplasty (TKA). METHODS: In a prospective randomised double-blinded study, 150 patients undergoing primary TKA were assigned to either a tourniquet or non-tourniquet group. At the early phase, 3 and 6 months after surgery, an independent observer assessed the primary outcome measure (i.e. total blood loss) and secondary outcome measures (i...

INTRODUCTION: The femoral stem should protrude from femur by an appropriate vertical distance to allow leg length equalization at hip arthroplasty; this distance depends on the size/shape of medullary canal and implant. The relationship between femoral morphology and achievability of leg length restoration is currently unclear. Our aim was to examine the impact of the femoral canal flare index (CFI) on the risk of leg length discrepancy (LLD) after total hip arthroplasty with different femoral stems...

INTRODUCTION: Patients with symptomatic spondylolisthesis are frequently treated with nerve root decompression, in addition to pedicle screw fixation and interbody fusion. Minimally invasive approaches are gaining attention in recent years, although there is no clear evidence supporting the proclamation of minimally invasive spine surgery (MISS) being better than open surgery. We present the design of the MISOS (Minimal Invasive Surgery versus Open Surgery) trial on the effectiveness of MISS versus open surgery in patients with degenerative or spondylolytic spondylolisthesis...

How do environmental conditions influence selection and genetic variation in wild populations? There is widespread evidence for selection-by-environment interactions (S*E), but we reviewed studies of natural populations estimating the extent of genotype-by-environment interactions (G*E) in response to natural variation in environmental conditions, and found that evidence for G*E appears to be rare within single populations in the wild. Studies estimating the simultaneous impact of environmental variation on both selection and genetic variation are especially scarce...

BACKGROUND AND PURPOSE: Elevated heel construction offloads the forefoot after surgery. However, side-to-side height difference alters limb kinetics, whereas leg-length equalizing-sole at non-operated side may have beneficial effects on foot loading. The purpose of this study was to characterize leg-length equalizing sole effect on bilateral plantar pressures when using heel-lift forefoot-offloading shoe. MATERIALS AND METHODS: Twenty men were tested walking. Plantar peak pressures (PP) and pressure-time integrals (PTI) in the forefoot-offloading shoe and in contralateral running shoe were compared between two conditions: one with- and the other without leg-length equalizing sole elevation at the running shoe...

Our prior work provides evidence that visual feedback distortion drives an implicit adaptation; a gradual distortion of visual representation of step length modulated subjects' step lengths away from symmetry. To further explore the effect of the visual feedback distortion on unconscious change in step symmetry, we investigated whether such adaptation would occur even in the presence of altered limb mechanics by adding mass to one side of the leg. 26 subjects performed three 8-min trials (weight only, weight plus visual feedback, and weight plus visual feedback distortion) of treadmill walking...

BACKGROUND: Full thickness skin graft (FTSG) gives better outcomes than split thickness skin graft (STSG), but it has the drawback of limited donor sites. Anterolateral thigh (ALT), a popular donor site of STSG, is also a popular donor site of perforator flaps. This area has the advantage of large flap size available with primary closure. Based on this we harvested FTSG instead of STSG from the ALT. METHODS: We retrospectively reviewed 10 cases of FTSG from the ALT, with the recipient site of foot in 3, ankle in 2, lower leg in 2, forearm in 2, and wrist in 1 patient...

Botulinum-toxin A (BoNT/A) is used for a wide range of conditions. Intramuscular administration of BoNT/A inhibits the release of acetylcholine at the neuromuscular junction from presynaptic motor neurons causing muscle-paralysis. The aim of the present study was to investigate the effect of high dose intramuscular BoNT/A injections (6 UI = 60 pg) on muscle tissue. The gait pattern of the rats was significantly affected 3 weeks after BoNT/A injection. The ankle joint rotated externally, the rats became flat footed, and the stride length decreased after BoNT/A injection...

BACKGROUND: While muscle regeneration has been extensively studied in animal and cell culture models, in vivo myogenesis in adult human skeletal muscle has not been investigated in detail. METHODS: Using forced lengthening contractions induced by electrical stimulation, we induced myofibre injury in young healthy males. Muscle biopsies were collected from the injured leg 7 and 30 days after muscle injury and from the uninjured leg as a control. Immuno-stained single muscle fibres and muscle cross sections were studied by wide-field and confocal microscopy...

We are interested in using wearable sensor data to analyze detailed characteristics of movement, such as repeatability and variability of movement patterns, over days and months to accurately capture real-world infant behavior. The purpose of this study was to explore Sample Entropy (SampEn) from wearable sensor data as a measure of variability of spontaneous infant leg movement and as a potential marker of the development of neuromotor control. We hypothesized that infants at risk (AR) of developmental delay would present significantly lower SampEn values than infants with typical development (TD)...

We compared the outcomes of nonoperative and operative treatments of triplane fractures. Thirty-three patients with triplane fractures were treated conservatively (n=19) or surgically (n=14). Bone union and postoperative complications were radiographically examined. The mean American Orthopedic Foot and Ankle Society scores were 100 (nonoperative group) and 98.1 (operative group) (P=0.304). The modified Weber protocol scores were excellent in both groups. One patient in each group showed a leg-length discrepancy of more than 10 mm at the last follow-up...

BACKGROUND: Dislocation following total hip arthroplasty (THA) remains a significant clinical problem. Few studies have focused on the use of dual mobility (DM) components in the setting of first-time revision for instability following THA. Here, we investigate patient outcomes following first-time revision THA with DM components for a diagnosis of instability. METHODS: Institution-wide revision THAs using DM components performed between 2010 and 2013 were identified...

This study was conducted to evaluate the effect of in ovo feeding of cationic amino acids on hatchability, hatch weights, and organ developments in pigeon squabs. Two experiments were conducted in this study. Eggs in Exp. 1 were subjected to modification of in ovo feeding in pigeons. Optimal time was determined by checking amniotic fluid volume, and suitable length was confirmed through ink injection. Results showed that the optimum time of in ovo feeding was on d 13 of embryonic development, and the suitable injected length was 20 mm to reach the amniotic cavity of the embryo...
