“…After settling, floating materials were filtered onto a 20 μm PCTE membrane filter and visually inspected using a Nikon SMZ745-T microscope. 8 .-This method is a density separation approach that uses both NaCl (ϱ=1.2g/cm 3 ) and sodium iodide (NaI) (ϱ =1.8g/cm 3 ) solutions. Sieved (<1mm) and dried sediment samples (1kg) were initially separated with air induced overflow (AIO), which uses an aerated NaCl solution for density separation.…”

“…With no sediment standard reference material for MPs, methods are developed with an array of sediment and plastic matrices. Sediments may go through pretreatment steps including oven drying [6][7][8] , presieving of coarse or fine materials 7,9 , or chemical oxidation. [9][10][11][12] The method efficacy is often dependent on sediment composition.…”

Plastic pollution in marine systems degrades over time through numerous weathering processes. Microplastics (MPs) are small (<1mm) plastic particles which pose potential threat to marine ecosystems. Identifying MPs in marine sediments is crucial for understanding their fate and effects on benthic communities. Many methods exist for the extraction of MPs from sediments, but procedural differences prevent meaningful comparisons across datasets. This method comparison examines the efficiency of five common methods for extracting MPs (40-710μm) from marine sediments. Known quantities of MPs (i.e., polyethylene, polystyrene, polyethylene terephthalate, polyvinyl chloride, and polypropylene) were spiked into two different sediment treatments (sand and silt). The MPs were extracted using five varying published methods and enumerated to demonstrate percent recovery. Findings determined that sediment matrix, MP properties, and extraction method all substantially affected the percent recovery of MPs from marine sediments. Average recoveries of spiked microplastics were between 0-87.4% and varied greatly by sediment type, microplastic, and method of extraction. In general, larger particle and lower density MPs were more effectively recovered. Marine sediments low in organic matter and with larger grain size (i.e., sand) also had higher percent recoveries of MPs. These findings support the need for method optimization and unified procedures when measuring environmental MP abundance in marine sediments.

“…The fragment is then reduced to the patella and secured by tying the four suture loops. Nuelle et al 13 describe a similar method for fixation of the osteochondral fragment using bioabsorbable screws. The main difference in this technique and the technique described in this Technical Note is the addition of microfracture in the osteochondral defect.…”

“…In 1988, Rae and Khasawneh 17 were the first to successfully use headless cannulated compression screws to fix large osteochondral fragments of the patella. Other authors [7][8][9]18,19 have reported small series of cases and case reports, showing excellent outcomes in acute OCFs managed by ORIF with screw fixation. Gesslein et al, 20 in a series of 36 acute OCFs located on the patellar surface, concluded that fixation shows improved clinical outcomes and is superior as compared with debridement.…”

Currently, the management of acute osteochondral fractures (OCFs) of the patella is well established. However, the management of chronic OCFs remains debatable, as it is not clear whether such lesions can be accurately reduced or whether they will reliably heal. With well proven results of open reduction and internal fixation (ORIF) with headless compression screws (HCS) for acute OCFs, the application of this technique in late presenting cases is inconclusive. Thus, we present the clinicoradiological outcome of patients with chronic osteochondral injuries managed with ORIF. Fifteen patients who underwent surgical fixation by ORIF with HCS for chronic OCFs of the patella, between February 2013 and June 2018, were retrospectively analyzed after a mean follow-up of 3.8 years (range: 2–7 years). The mode of injury, size of the osteochondral fragment, and knee range of motion along with Kujala's scoring were examined clinically and radiological assessment was done by X-rays and magnetic resonance imaging (MRI) scans. Fifteen patients (11 males and 4 females), with a mean age of 17 years with chronic OCF of patella were enrolled. Noncontact twisting injuries were the most common mode of injury seen in 86.66% of patients and postcontact injuries in two patients (13.33%). The mean time from trauma to presentation was 7 weeks (range: 6–14 weeks). The mean preoperative Kujala's score improved from 44 to 84.8 at 6 months and 92.6 at 2 years, postoperatively. Intraoperatively, the lesion was found in medial patellar facet in 12 patients and 3 had lesions in the central facet. The mean size of the lesion was 20 mm × 18 mm. Radiological union was observed in all patients, at a mean duration of 16 weeks (range: 12–20 weeks). One patient underwent implant removal 1 year after initial surgery for mechanical symptoms. ORIF of OCFs of the patella using headless cannulated screws is simple, reliable, reproducible, and provides satisfactory outcomes. This technique can be considered for fixation of fragments with adequate subchondral bone.
