Gender Disparity between Absolute versus Relative Size of Condylar Chondral Defects: An MRI Analysis

J Knee Surg DOI: 10.1055/s-0038-1646932Surgical repair of articular cartilage defects in the knee currently utilizes surgical algorithms based on absolute defect size. These algorithms, which have not been validated, are currently utilized not only by surgeons but also by insurance carriers for justification of reimbursement policy. However, current algorithms do not account for morphological differences between individual patients and defect size relative to condylar dimension. We hypothesized that a significant difference in relative defect size compared with condylar dimension may exist between individuals. A 3T magnetic resonance imaging from 220 skeletally mature patients, 110 males and 110 females, were analyzed. Exclusion criteria included degenerative arthritis, anatomical defects, poor image quality, and genetic abnormalities such as dwarfism. Utilizing a radiological curved measurement probe, the femoral condylar articular width was obtained for both the medial and lateral condyles. The mean condylar width from a reproducible anatomic location representing the maximal condylar dimension was measured. Statistical analysis was performed using a two-sample t-test. The lateral condyle articular cartilage width (mm) for males and females was 31.62 ± 3.54 and 26.53 ± 3.70, respectively (p

Authors: Yue J, Wu D, Tam LS Abstract INTRODUCTION: Inflammatory arthritis is characterized by chronic inflammation in the synovium, associated with degradation of cartilage and erosion of juxta-articular bone. The bone loss and joint destruction mediated by aberrant immunological responses resulting in proinflammatory cytokine release and various immune cell activation are known as osteoimmunology. Areas covered: A structured literature search including Medline and PubMed, Cochrane meta-analyses and abstracts of international congresses was performed to review joint damage in inflammatory arthritis in terms of pa...

CONCLUSION: Our study showed that even if rotator cuff tears are repaired, the progression of osteoarthritic changes cannot be halted. The progression of OA was affected by cuff integrity. Rotator cuff dysfunction due to poor cuff integrity was a risk factor for shoulder arthritis. PMID: 29635956 [PubMed - in process]

In conclusion, most experimental data on immune changes with aging show a decline in many immune parameters when compared to young healthy subjects. The bulk of these changes is termed immunosenescence. Immunosenescence has been considered for some time as detrimental because it often leads to subclinical accumulation of pro-inflammatory factors and inflammaging. Together, immunosenescence and inflammaging are suggested to stand at the origin of most of the diseases of the elderly, such as infections, cancer, autoimmune disorders, and chronic inflammatory diseases. However, an increasing number of gerontologists have chall...

In this study, we asked people in an open-ended way about their desire for longer life: Would you like to have more time? What age would you like to become? This was something more specific than asking about a preference for survival without reference to any length of time; about one's plans for the future; or whether people see the future as open or limited, as in studies of future time perspective. Our attempt was to discover whether there were preferred temporal spans with which older adults framed their futures and plans. The two-question series about extra years and desired age ("How old would you like to ...

This study developed the first procedure for the removal of epithelium from the lung airway with the full preservation of vascular epithelium, which could be applied in vivo to treat diseases of lung epithelium. Whole lung scaffolds with an intact vascular network may also allow for recellularization using patient-specific cells and bioengineering of chimeric lungs for transplantation. In addition to the clinical potential, lung scaffolds lacking an intact epithelial layer but with functional vascular and interstitial compartments may also serve as a valuable physiological model for investigating (i) lung development, (ii)...

Abstract This case report describes a 42-year-old woman who was diagnosed with pigmented villonodular synovitis (PVNS) in the knee. The patient had received a bone-patella tendon-bone autograft reconstruction of her anterior cruciate ligament (ACL) 22 years prior to her diagnosis of PVNS. After a traumatic event that tore her ACL graft, she underwent a second surgery to repair the initial reconstruction. However, her pain and joint instability remained unresolved. When radiolucent lesions in her tibia and femur were identified through a radiographic image, the patient was referred to the authors' orthopedic oncolo...

Abstract AimTo examine the efficacy of abatacept in patients with rheumatoid arthritis (RA) using magnetic resonance imaging (MRI) of bilateral hands. MethodThis prospective study included 35 RA patients. MRI of bilateral hands was performed at baseline and after 12 months of treatment with intravenous abatacept. MRI images were scored for synovitis, osteitis, erosion and joint space narrowing (JSN) according to the RA MRI Scoring System (RAMRIS). The primary endpoint was the change in RAMRIS score from baseline. Repair of erosion was defined as a negative change in the erosion score that was greater than the smallest...

AbstractObjective. To examine the relationship between MRI structural damage and repair and plasma inflammatory cytokines in patients with RA.Methods. A total of 88 newly diagnosed, untreated RA patients were enrolled. Contrast MRI of the dominant hand and X-rays of the hands and feet were performed at baseline and 1 year later. MR images were evaluated using RA MRI scoring, and X-raywere assessed by the modified total Sharp score. Erosion progression was defined as changes in RA MRI scoring erosion or modified total Sharp score erosion of>0.5. Erosion repair was defined as erosion score changes of less than −0.5....
