Research shows autologous chondrocyte implantation (ACI) is a promising treatment for articular cartilage lesions. In this study, we assessed mid-term efficacy and safety of gel-based ACI or autologous adult live cultured chondrocytes (CARTIGROW®) implantation in patients with cartilage defects of the knee joint.

In this prospective, open-label study, patients (19-38years) with focal, international cartilage repair society grade III or IV articular cartilage defects of the knee joint were enroled at four centres across India from April 2015 to September 2015. Punch biopsy was conducted to harvest cartilage, from which chondrocytes were isolated and cultured, and the characterised chondrocytes were implanted into the cartilage defect. Key efficacy outcomes were assessed by quantitative changes in international knee documentation committee (IKDC), visual analogue scale (VAS) scores, and qualitative changes in magnetic resonance imaging at sixmonths and fouryears from baseline.

Of the14 patients enroled in the study, all patients completed the sixmonth follow-up and 11 completed the fouryear follow-up. The IKDC score improved significantly from 32.84 ± 9.25 at baseline to 67.49 ± 13.03 at sixmonths (mean difference [MD] 34.66 ± 13.00, p < 0.0001) and to 60.18 ± 10.33 at fouryears (MD 28.21 ± 15.14, p = 0.0001). The VAS score reduced from 72.00 ± 14.40 at baseline to 16.64 ± 17.03 at sixmonths (MD 55.36 ± 24.50, p < 0.0001) and further to 12.72 ± 9.05 at fouryears (MD 62.09 ± 10.66, p < 0.0001). All patients showed improvement on MRI of the knee joint. WAY-EKI 785 No adverse events were reported.

Autologous adult live cultured chondrocytes (CARTIGROW®) implantation showed good mid-term efficacy in patients with cartilage defects of the knee joint with no side-effects.

Accurate detection of leptomeningeal metastasis (LM) is critical for risk stratification and treatment of pediatric brain tumors. Poor-quality staging MRI has been associated with decreased survival in this population, but technical factors differentiating good from poor quality screening MRIs remain undefined. To test the hypothesis that key technical factors are associated with accurate MRI diagnosis of leptomeningeal metastasis in children with leptomeningeal seeding brain tumors.

MRIs acquired at outside facilities and repeated in our institution within 35days for 75 children with leptomeningeal seeding tumors were assessed for slice thickness and gap; use of T2 FLAIR + Contrast, acquisition plane of 3DT1WI + Contrast (brain); axial T1 + Contrast sequence, and use of pre-contrast T1 images (spine). Reported findings were recorded as positive, negative, or equivocal for LM and classified as true positive (TP; unequivocal metastasis), false negative (FN; not reported), false positive (FP; resolved without treatment), or true negative. Wilcoxon signed-rank and Fisher's exact test were used to assess technical differences between TP and FN MRIs.

Rate of LM detection was greater with smaller interslice gap in brain (P = 0.003) and spine (P = 0.002); use of T2 FLAIR + Contrast (P = 0.005) and sagittal plane for 3DT1WI + Contrast (P = 0.028) in brain; and use of alternatives to axial TSE/FSE in spine (P = 0.048). Slice thickness was not significant. Pre-contrast T1WI did not contribute to LM diagnosis in spine.

Using post-contrast T2 FLAIR and sagittal 3DT1 in brain, small/no interslice gap, and avoiding TSE/FSE axials in spine may facilitate leptomeningeal metastasis detection in children with brain tumors.

The ipsilateral hand (ILH) is impaired after unilateral stroke, but the underlying mechanisms remain unresolved. Based on the degeneracy theory of network connectivity that many connectivity patterns are functionally equivalent, we hypothesized that ILH impairment would result from the summation of microstructural white matter (WM) disruption in the motor network, with a task-related profile. We aimed to determine the WM disruption patterns associated with ILH impairment.

This was a cross-sectional analysis of patients in the ISIS-HERMES Study with ILH and diffusion-MRI data collected 1month post-stroke. Patients performed three tasks, the Purdue Pegboard Test (PPT), handgrip strength, and movement time. Fractional anisotropy (FA) derived from diffusion MRI was measured in 33 WM regions. We used linear regression models controlling for age, sex, and education to determine WM regions associated with ILH impairment.

PPT was impaired in 42%, grip in 59%, and movement time in 24% of 29 included patients (meWe propose to integrate ILH assessment in rehabilitation programs and treatment interventions such as neuromodulation.The central nervous system utilizes tendon compliance of the intrinsic foot muscles to aid the foot's arch spring, storing and returning energy in its tendinous tissues. Recently, the intrinsic foot muscles have been shown to adapt their energetic contributions during a variety of locomotor tasks to fulfil centre of mass work demands. However, the mechanism by which the small intrinsic foot muscles are able to make versatile energetic contributions remains unknown. Therefore, we examined the muscle-tendon dynamics of the flexor digitorum brevis during stepping, jumping and landing tasks to see whether the central nervous system regulates muscle activation magnitude and timing to enable energy storage and return to enhance energetic contributions. In step-ups and jumps, energy was stored in the tendinous tissue during arch compression; during arch recoil, the fascicles shortened at a slower rate than the tendinous tissues while the foot generated energy. In step-downs and landings, the tendinous tissues elongated more and at greater rates than the fascicles during arch compression while the foot absorbed energy. These results indicate that the central nervous system utilizes arch compression to store elastic energy in the tendinous tissues of the intrinsic foot muscles to add or remove mechanical energy when the body accelerates or decelerates. This study provides evidence for an adaptive mechanism to enable the foot's energetic versatility and further indicates the value of tendon compliance in distal lower limb muscle-tendon units in locomotion.
Operations for lumbar spinal stenosis is the most often performed surgical procedure in the adult lumbar spine. This study reports the clinical outcome of the 3 most commonly used minimally invasive posterior decompression techniques.

To compare the effectiveness of 3 minimally invasive posterior decompression techniques for lumbar spinal stenosis.

This randomized clinical trial used a parallel group design and included patients with symptomatic and radiologically verified lumbar spinal stenosis without degenerative spondylolisthesis. Patients were enrolled between February 2014 and October 2018 at the orthopedic and neurosurgical departments of 16 Norwegian public hospitals. Statistical analysis was performed in the period from May to June 2021.

Patients were randomized to undergo 1 of the 3 minimally invasive posterior decompression techniques unilateral laminotomy with crossover, bilateral laminotomy, and spinous process osteotomy.

Primary outcome was change in disability measured with Oswestry D8), and the spinous process osteotomy group had a mean change of -19.9 ODI points (95% CI, -22.8 to -17.0). There were no significant differences in primary or secondary outcomes among the 3 surgical procedures, except a longer duration of the surgical procedure in the bilateral laminotomy group.

No differences in clinical outcomes or complication rates were found among the 3 minimally invasive posterior decompression techniques used to treat patients with lumbar spinal stenosis.
