    UNASSIGNED: Cartilage lesions of the patellofemoral joint constitute a frequent abnormality. Patellofemoral conditions are challenging to treat because of complex biomechanics and morphology.
    UNASSIGNED: To develop a consensus statement on the functional anatomy, indications, donor graft considerations, surgical treatment, and rehabilitation for the management of large chondral and osteochondral defects in the patellofemoral joint using a modified Delphi technique.
    UNASSIGNED: Consensus statement.
    UNASSIGNED: A working group of 4 persons generated a list of statements related to the functional anatomy, indications, donor graft considerations, surgical treatment, and rehabilitation for the management of large chondral and osteochondral defects in the patellofemoral joint to form the basis of an initial survey for rating by a group of experts. The Metrics of Osteochondral Allografts (MOCA) expert group (composed of 28 high-volume cartilage experts) was surveyed on 3 occasions to establish a consensus on the statements. In addition to assessing agreement for each included statement, experts were invited to propose additional statements for inclusion or to suggest modifications of existing statements with each round. Predefined criteria were used to refine statement lists after each survey round. Statements reaching a consensus in round 3 were included within the final consensus document.
    UNASSIGNED: A total of 28 experts (100% response rate) completed 3 rounds of surveys. After 3 rounds, 36 statements achieved a consensus, with over 75% agreement and less than 20% disagreement. A consensus was reached in 100.00% of the statements relating to functional anatomy of the patellofemoral joint, 88.24% relating to surgical indications, 100.00% relating to surgical technical aspects, and 100.00% relating to rehabilitation, with an overall consensus of 95.5%.
    UNASSIGNED: This study established a strong expert consensus document relating to the functional anatomy, surgical indications, donor graft considerations for osteochondral allografts, surgical technical aspects, and rehabilitation concepts for the management of large chondral and osteochondral defects in the patellofemoral joint. Further research is required to clinically validate the established consensus statements and better understand the precise indications for surgery as well as which techniques and graft processing/preparation methods should be used based on patient- and lesion-specific factors.

    异基因造血干细胞移植后肺部并发症经常发生(30-75%),严重程度不同,有时被证明是致命的。它们可能在D100之前的移植后早期发生,但也可能在以后出现。对这些并发症的病因支持已显示出对生存的有益影响。当面临早期并发症时,非侵入性测试,扫描,和微生物测试必须迅速实施。在大多数情况下,这些测试有助于诊断。在微生物非侵入性测试为阴性的情况下,病人表现出稳定的呼吸状况,如果在出现肺部症状后的前四天内实施支气管肺泡灌洗,则可以有效。这种诊断方法绝不应阻碍在这些严重免疫功能低下的患者中引入广谱抗生素。后来的肺部并发症是最常见的非传染性的。它们包括不同的解剖临床条件:隐源性机化性肺炎;间质性肺病;特发性胸膜实质纤维弹变性。血管疾病可能包括高血压,血栓性微血管病,静脉血栓栓塞,和胸腔积液.必须使用允许早期检测和治疗干预的RFE(呼吸功能探查)来监测这些状况。RFE和胸部放射学扫描的组合将提供诊断评估。当怀疑感染或全身皮质类固醇治疗之前,应进行支气管肺泡灌洗。肺活检应根据具体情况进行讨论,例如间质性肺病的病例。
    Pulmonary complications after allogeneic hematopoietic stem cell transplantation occur frequently (30-75%), vary in severity, and sometimes prove lethal. They may occur at an early stage post-transplant before D100 but may also surface later. Etiological support for these complications has shown a beneficial impact on survival. When faced with early complications, non-invasive tests, scans, and microbiological tests must be rapidly implemented. In the majority of cases, these tests facilitate diagnosis. In cases where microbiological non-invasive tests are negative, and the patient shows a steady respiratory condition, bronchoalveolar lavage can be effective if it is implemented in the first four days following the onset of pulmonary symptoms. This diagnostic approach should in no way occlude the introduction of broad-spectrum antibiotics in these profoundly immunocompromised patients. Later pulmonary complications are the most often not infectious. They include different anatomo-clinical conditions: cryptogenic organizing pneumonia; interstitial lung disease; idiopathic pleuroparenchymal fibroelastosis. Vascular disorders may include hypertension, thrombotic microangiopathy, venous thromboembolism, and pleural effusions. These conditions must be monitored using RFE (respiratory functional exploration) which allows early detection and therapeutic intervention. A combination of RFE and thoracic radiology scans will provide diagnostic assessment. Bronchoalveolar lavage is indicated when an infection is suspected or before systemic corticosteroid therapy. A lung biopsy should be discussed on a case-by-case basis, such as in cases of interstitial pulmonary disorders.

    Neurological complications post-allogeneic hematopoietic stem cell transplantation are well-characterized; however, given their variable impact, they remain a significant cause of morbidity. The etiologies for these complications are vast. Causes may be linked to toxicity and infection or could be vascular or tumor-related. Regardless, these complications require early investigation, which is often multidisciplinary and hierarchical. Preventive measures may be considered in some situations. It is essential to respond early and quickly with a diagnosis and the appropriate therapeutic approach when faced with neurological complications. Focusing on the axes of etiology, diagnosis and treatment, this article offers a review of neurological complications post-allogeneic hematopoietic stem cell transplantation.

    The evidence supporting best practice guidelines in the field of cartilage repair of the ankle is based on both low quality and low levels of evidence. Therefore, an international consensus group of experts was convened to collaboratively advance toward consensus opinions based on the best available evidence on key topics within cartilage repair of the ankle. The purpose of this article is to report the consensus statements on \"Osteochondral Allograft\" developed at the 2017 International Consensus Meeting on Cartilage Repair of the Ankle.
    Seventy-five international experts in cartilage repair of the ankle representing 25 countries and 1 territory were convened and participated in a process based on the Delphi method of achieving consensus. Questions and statements were drafted within 11 working groups focusing on specific topics within cartilage repair of the ankle, after which a comprehensive literature review was performed and the available evidence for each statement was graded. Discussion and debate occurred in cases where statements were not agreed upon in unanimous fashion within the working groups. A final vote was then held, and the strength of consensus was characterized as follows: consensus, 51% to 74%; strong consensus, 75% to 99%; and unanimous, 100%.
    A total of 15 statements on osteochondral allograft reached consensus during the 2017 International Consensus Meeting on Cartilage Repair of the Ankle. One achieved unanimous support and 14 reached strong consensus (greater than 75% agreement). All statements reached at least 85% agreement.
    This international consensus derived from leaders in the field will assist clinicians with osteochondral allograft as a treatment strategy for osteochondral lesions of the talus.

    OBJECTIVE: Graft choice for primary anterior cruciate ligament reconstruction (ACL-R) is debated, with considerable controversy and variability among surgeons. Autograft tendons are actually the most used grafts for primary surgery; however, allografts have been used in greater frequency for both primary and revision ACL surgery over the past decade. Given the great debate on the use of allografts in ACL-R, the \"Allografts for Anterior Cruciate Ligament Reconstruction\" consensus statement was developed among orthopedic surgeons and members of SIGASCOT (Società Italiana del Ginocchio, Artroscopia, Sport, Cartilagine, Tecnologie Ortopediche), with extensive experience in ACL-R, to investigate their habits in the use of allograft in different clinical situations. The results of this consensus statement will serve as benchmark information for future research and will help surgeons to facilitate the clinical decision making.
    METHODS: In March 2017, a formal consensus process was developed using a modified Delphi technique method, involving a steering group (9 participants), a rating group (28 participants) and a peer-review group (31 participants). Nine statements were generated and then debated during a SIGASCOT consensus meeting. A manuscript has been then developed to report methodology and results of the consensus process and finally approved by all steering group members.
    RESULTS: A different level of consensus has been reached among the topics selected. Strong agreement has been reported in considering harvesting, treatment and conservation methods relevant for clinical results, and in considering biological integration longer in allograft compared to autograft. Relative agreement has been reported in using allograft as the first-line graft for revision ACL-R, in considering biological integration a crucial aspect for rehabilitation protocol set-up, and in recommending a delayed return to sport when using allograft. Relative disagreement has been reported in using allograft as the first-line graft for primary ACL-R in patients over 50, and in not considering clinical results of allograft superior to autograft. Strong disagreement has been reported in using allograft as the first-line graft for primary ACL-R and for skeletally immature patients.
    CONCLUSIONS: Results of this consensus do not represent a guideline for surgeons, but could be used as starting point for an international discussion on use of allografts in ACL-R.
    METHODS: IV, consensus of experts.
