Quantitative MRI T2 Relaxation Time Evaluation of Knee Cartilage
TLDR
It is demonstrated that knees with meniscectomy or meniscal repair had articular cartilage degeneration at 2 to 4 years postoperatively, with higher articularcartilage T2 relaxation time values compared with the knees with an intact meniscus.
Difference in Graft Maturity of the Reconstructed Anterior Cruciate Ligament 2 Years Postoperatively
TLDR
The allograft group had a significantly higher SNQ value compared with the autografted group in this study, indicating that allografted tendons might have inferior graft maturity than autograft tendons in ACL reconstruction at 2 years postoperatively.
Quantitative magnetic resonance imaging (MRI) evaluation of cartilage repair after microfracture (MF) treatment for adult unstable osteochondritis dissecans (OCD) in the ankle: correlations with
TLDR
Significant improvement from MF can be expected on the basis of the outcomes of quantitative MRI and AOFAS score, and the reduction of subchondral BME will improve the patient’s clinical outcome.
Correlation Analysis of Potential Factors Influencing Graft Maturity After Anterior Cruciate Ligament Reconstruction
TLDR
The graft SNQ value had a significant positive correlation with physical activity level and a significant negative correlation with postoperative time in this study, which may be a cause for concern.
Morphological Changes of the Femoral Tunnel and Their Correlation With Hamstring Tendon Autograft Maturation up to 2 Years After Anterior Cruciate Ligament Reconstruction Using Femoral Cortical
TLDR
After ACLR using suspensory fixation, morphological changes of the femoral tunnel were mainly observed in the part of the tunnel containing the graft, which expanded at 6 months and reduced by 24 months, but not with clinical outcomes.
Opportunistic Screening Using Low‐Dose CT and the Prevalence of Osteoporosis in China: A Nationwide, Multicenter Study
TLDR
It is shown that LDCT‐based opportunistic screening could identify large numbers of patients with low lumbar vBMD, and that future cohort studies are now required to evaluate the clinical utility of such screening in terms of fracture prevention and supporting national health economic analyses.
Clinical and magnetic resonance imaging assessment of anatomical lateral ankle ligament reconstruction: comparison of tendon allograft and autograft
TLDR
Both allograft and autograft reconstructions could get an ideal patient satisfaction and clinical functional outcomes at the follow-up according to the results of anatomical lateral ankle ligament (LAL) reconstruction using clinical scores and ultrashort echo time (UTE) sequence of MRI.
Quantitative T2-Mapping and T2⁎-Mapping Evaluation of Changes in Cartilage Matrix after Acute Anterior Cruciate Ligament Rupture and the Correlation between the Results of Both Methods
TLDR
The early degeneration could occur in various knee cartilage compartments after acute ACL rupture, especially in the superficial layer of LT, and T2⁎-mapping might be more sensitive in detecting deep layer of cartilage than T2- mapping.
Quantitative magnetic resonance imaging (MRI) evaluation of cartilage repair after microfracture treatment for full-thickness cartilage defect models in rabbit knee joints: correlations with
TLDR
MRI was correlated with the histological O’Driscoll score, which indicated that quantitative MRI 3D-DESS and T2 mapping could evaluate cartilage repair after microfracture as an effective noninvasive tool.
