chondromalacia patella femoral trochlea morphology magnetic resonance imaging |
Résumé : |
The aim of this study was to evaluate trochlear morphology in patients with medial patellar cartilage defects via magnetic resonance imaging (MRI).
Three hundred patients who were diagnosed with grade 2, 3 and 4 medial patellar cartilage defect using MRI according to the International Cartilage Repair Society Classification System and 100 control subjects were evaluated. Trochlear morphology was evaluated based on lateral trochlear inclination (LTI), medial trochlear inclination (MTI), sulcus angle( SA), femoral lateral and medial condyle symmetry, trochlear facet asymmetry, and trochlear width on the axial MR images.
The mean SA was significantly higher in the medial patellar cartilage defect group compared to the control group (p<.05). The LTI and MTI of the cartilage defect group were significantly lower than those of the control group (p<.05). With the decreasing LTI and MTI, there was an increase in medial patellar cartilage loss. LTI (r=-0.46) and MTI (r=-0.53) were moderately correlated with SA. There was no significant differences in femoral lateral and medial condyle symmetry, trochlear facet asymmetry, and trochlear width between groups with and without medial patellar cartilge defect (p > .05).
A flattened medial trochlea is a risk factor for cartilage structural damage of the medial patellofemoral joint, and it plays a role in the development of a defect in the medial patellar cartilage. The medial patellar cartilage defect is associated with the flattened lateral trochlea. |

ultrasonography magnetic resonance imaging rotator cuff tear meta-analysis accuracy |
Résumé : |
To review the diagnostic performance of ultrasonography (US) and magnetic resonance imaging (MRI) for the detection of rotator-cuff tears, we performed a retrospective audit of patients who underwent shoulder arthroscopy at Hinchingbrooke hospital. The diagnostic accuracies of US for full and partial-thickness tears were 82% and 28% respectively. Those of MRI were 82% and 81% respectively. These were lower than expected from the literature. This discrepancy is likely to be the consequence of over-diagnosis in imaging and under-diagnosis at arthroscopy. |

Magnetic resonance imaging Quadriceps muscle Hamstring Muscle cross-sectional area Knee osteoarthritis |
Résumé : |
Background
The characteristics of thigh-muscle cross-sectional area (CSA) in older adults with knee osteoarthritis (KOA) remain controversial.
Objectives
This study aimed to evaluate atrophy of individual thigh muscles in older adults with KOA and to determine which muscle CSA should be measured to detect KOA-related muscle atrophy of the thigh.
Methods
In older adults, individual thigh-muscle CSA measured by 1.5 Tesla MRI was analyzed at 5% intervals of the femoral length (FL) around the mid-thigh between the proximal 25% of the FL and the distal 25%. Participants with KOA grade ≤ 1 and grade ≥ 2 were compared for ratios of quadriceps muscle (QM) CSA to total thigh, individual QM CSA to QM, and individual hamstring (HAM) CSA to HAM at 5% intervals.
Results
We included 40 older adults [20 males; mean (SD) age 73.3 (4.7) years; 20 with KOA grade ≤ 1 and 20 with KOA grade ≥ 2]. The ratio of vastus medialis (VM) CSA to QM from the proximal 25% to distal 15% and the ratio of semi-membranosus (SM) CSA to HAM at the distal 10% to 25% were significantly lower with KOA grade ≥ 2 than grade ≤ 1; the effect sizes were 0.34 to 0.67 for VM and 0.40 to 0.60 for SM. The effect sizes were greatest for the ratios of VM CSA to QM at the mid-thigh with 5% intervals and the ratio of SM CSA to HAM at the distal 25%.
Conclusions
The ratio of VM CSA to QM and/or that of SM CSA to HAM were low and were the best indicators to detect KOA-related muscle atrophy of the thigh. However, to detect KOA-related muscle atrophy, the VM CSA ratio should be analyzed in the thigh region around the mid-thigh, whereas the SM CSA ratio should be analyzed in the thigh region at the muscle belly. |

Résumé : |
The aim of this study was to evaluate the associations between patellar cartilage defects and body mass index (BMI), infrapatellar fat pad (IPFP) volume and age. 100 patients who met the inclusion criteria and were aged 18 to 60, were evaluated retrospectively. For detecting and measuring patellar cartilage defects, axial sequences were used and sagittal sequences were used to evaluate IPFP volumes. In total, 40 patients had patellar cartilage defects. In this group, age and BMI were higher in both sexes when compared with the controls (p < 0.05). The IPFP volume was lower in the group with the patellar cartilage defect when compared with the control group (p < 0.05). The IPFP volume was statistically significantly lower in women (p < 0.05). Patellar cartilage defect was found to be related to age and BMI. In women, the decrease in IPFP volume seems to be one of the causative factors for patellar cartilage defect. |
