ObjectivesTo summarise recommendations and appraise the quality of international clinical practice guidelines (CPGs) for rehabilitation after ACL reconstruction.DesignSystematic review of CPGs (PROSPERO number: CRD42017020407).Data sourcesPubmed, EMBASE, Cochrane, SPORTDiscus, PEDro and grey literature databases were searched up to 30 September 2018.Eligibility criteriaEnglish-language CPGs on rehabilitation following ACL reconstruction that used systematic search of evidence to formulate recommendations.MethodsWe followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to report the systematic review. Two appraisers used the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument to report comprehensiveness, consistency and quality of CPGs. We summarised recommendations for rehabilitation after ACL reconstruction.ResultsSix CPGs with an overall median AGREE II total score of 130 points (out of 168) and median overall quality of 63% were included. One CPG had an overall score below the 50% (poor quality score) and two CPGs scored above 80% (higher quality score). The lowest domain score was ‘applicability’ (can clinicians implement this in practice?) (29%) and the highest ‘scope and purpose’ (78%) and ‘clarity of presentation’ (75%). CPGs recommended immediate knee mobilisation and strength/neuromuscular training. Early full weight-bearing exercises, early open and closed kinetic-chain exercises, cryotherapy and neuromuscular electrostimulation may be used according individual circumstances. The CPGs recommend against continuous passive motion and functional bracing.ConclusionThe quality of the CPGs in ACL postoperative rehabilitation was good, but all CPGs showed poor applicability. Immediate knee mobilisation and strength/neuromuscular training should be used. Continuous passive motion and functional bracing should be eschewed.
AimsThe purpose of this study was to compare the effects of hamstring eccentric (NHE) strength training versus sprint training programmed as complements to regular soccer practice, on sprint performance and its mechanical underpinnings, as well as biceps femoris long head (BFlh) architecture. MethodsIn this prospective interventional control study, sprint performance, sprint mechanics and BFlh architecture variables were compared before versus after six weeks of training during the first six preseason weeks, and between three different random match-pair groups of soccer players: "Soccer group" (n = 10), "Nordic group" (n = 12) and "Sprint group" (n = 10).The results suggest that sprint training was superior to NHE in order to increase BFlh fascicle length although only the sprint training was able to both provide a preventive stimulus (increase fascicle length) and at the same time improve both sprint performance and mechanics. Further studies with advanced imaging techniques are needed to confirm the validity of the findings. Architectural and performance effects of different training programs PLOS ONE | https://doi.
The Ecological Risk Assessment of pesticides requires data regarding their toxicity to aquatic and terrestrial non-target species. Such requirements concern active ingredient(s), generally not considering the noxious potential of commercial formulations. This work intends to contribute with novel information on the effects of short-term exposures to two herbicides, with different modes of action (Spasor, Stam Novel Flo 480), and an insecticide (Lannate), as well as to corresponding active ingredients (Glyphosate, Propanil and Methomyl, respectively). The microalga Pseudokirchneriella subcapitata (growth inhibition), the cladoceran Daphnia magna (immobilisation), and the earthworm Eisenia andrei (avoidance behaviour) were used as test species. Both herbicides were innocuous to all test organisms at environmentally realistic concentrations, except for Stam and Propanil (highly toxic for Pseudokirchneriella; moderately toxic to Daphnia). Lannate and Methomyl were highly toxic to Daphnia and caused Eisenia to significantly avoid the spiked soil at realistic application rates. The toxicity of formulations either overestimated (e.g. Stam/Propanil for P. subcapitata) or underestimated (e.g. Stam/Propanil for D. magna) that of the active ingredient.
BackgroundMosaicplasty has been associated with good short- to long-term results. Nevertheless, the osteochondral harvesting is restricted to the donor-site area available and it may lead to significant donor-site morbidity.PurposeProvide an overview of donor-site morbidity associated with harvesting of osteochondral plugs from the knee joint in mosaicplasty procedure.MethodsComprehensive search using Pubmed, Cochrane Library, SPORTDiscus and CINAHL databases was carried out through 10th October of 2016. As inclusion criteria, all English-language studies that assessed the knee donor-site morbidity after mosaicplasty were accepted. The outcomes were the description and rate of knee donor-site morbidity, sample’s and cartilage defect’s characterization and mosaicplasty-related features. Correlation between mosaicplasty features and rate of morbidity was performed. The methodological and reporting quality were assessed according to Coleman’s methodology score.ResultsTwenty-one studies were included, comprising a total of 1726 patients, with 1473 and 268 knee and ankle cartilage defects were included. The defect size ranged from 0.85 cm2 to 4.9 cm2 and most commonly 3 or less plugs (averaging 2.9 to 9.4 mm) were used. Donor-site for osteochondral harvesting included margins of the femoral trochlea (condyles), intercondylar notch, patellofemoral joint and upper tibio-fibular joint. Mean donor-site morbidity was 5.9 % and 19.6 % for knee and ankle mosaicplasty procedures, respectively. Concerning knee-to-knee mosaicplasty procedures, the most common donor-site morbidity complaints were patellofemoral disturbances (22 %) and crepitation (31 %), and in knee-to-ankle procedures there was a clear tendency for pain or instability during daily living or sports activities (44 %), followed by patellofemoral disturbances, knee stiffness and persistent pain (13 % each). There was no significant correlation between rate of donor-site morbidity and size of the defect, number and size of the plugs (p > 0.05).ConclusionsOsteochondral harvesting in mosaicplasty often results in considerable donor-site morbidity. The donor-site morbidity for knee-to-ankle (16.9 %) was greater than knee-to-knee (5.9 %) mosaicplasty procedures, without any significant correlation between rate of donor-site morbidity and size of the defect, number and size of the plugs. Lack or imcomplete of donor-site morbidity reporting within the mosaicplasty studies is a concern that should be addressed in future studies.Level of evidenceLevel IV, systematic review of Level I-IV studies.
