1. Ultrasound-Guided Motor-Sparing Knee Blocks for Postoperative Analgesia Following Total Knee Arthroplasty: A Randomized Blinded Study

Ultrasound-Guided Motor-Sparing Knee Blocks for Postoperative Analgesia Following Total Knee Arthroplasty: A Randomized Blinded Study Pain following total knee arthroplasty (TKA) is often severe and can inhibit rehabilitation. Motor-sparing analgesic techniques such as periarticular infiltrations and adductor canal blocks have been popularized for knee analgesia since they preserve motor strength and permit early mobilization. Our primary objective was to compare the duration of analgesia from (...) the ultrasound-guided adductor canal block by combining it with a lateral femoral cutaneous nerve block and posterior knee infiltration. The patients, surgeons, anesthetists administering the blocks, and outcome assessors all remained blinded to group allocation. Our primary outcome was duration of analgesia (time to first rescue analgesia). Secondary outcomes included quadriceps strength, function, side effects, satisfaction, and length of hospital stay.The duration of analgesia was significantly longer

Efficacy of extracorporeal shockwave therapy and low-intensity pulsed ultrasound in a rat knee osteoarthritis model: A randomized controlled trial This study aims to assess the efficacy of extracorporeal shockwave therapy (ESWT) and low-intensity pulsed ultrasound (LIPUS) on osteoarthritic rat knees.Twenty-four rats were divided into 3 groups: group 1-control (n=8), group 2-LIPUS (n=8) and group 3-ESWT (n=8). Cartilage degeneration was provided using mono-iodo-asetate (MIA). One milligram (...) of MIA was delivered to the right knees in group 1 and both knees in group 2 and 3. A 0.09% saline solution was delivered to the left knees in group 1 for control. Twenty-four hours after the delivery, ESWT was applied once on the right knees in the group 2 rats to the medial tibia plateu with a 1 Hz frequency and 800 impulses. LIPUS was applied to the right knees in the group 2 rats to the medial tibia plateu with a 3 mHz frequency and 40 mW/cm2 intensity for 20 minutes over a period of 15 days

7. Ultrasound measurement of knee synovial fluid during external pneumatic compression. (PubMed)

Ultrasound measurement of knee synovial fluid during external pneumatic compression. Synovial fluid based biomarker research has been limited by the small volumes of synovial fluid from the knees of some patients. We used ultrasound (US) to determine if synovial fluid could be displaced into an access port during pneumatic compression to 100 mmHg. Forty knees from 37 consecutive arthritis patients with rheumatoid arthritis -25, osteoarthritis -8, psoriatic arthritis -2, and 1 each with systemic (...) lupus erythematosus and gout were evaluated. This group of 28 females and 9 males with a median age of 59 years and an average body mass index of 26.9 kg/m2 had previously undergone a diagnostic arthrocentesis and or a therapeutic knee injection using this pneumatic compression device. Blinded digital image analysis of the anechoic region on ultrasound demonstrated an increase in fluid within the 9 cm × 6 cm access port (anterolateral or anteromedial joint) during inflation in all patients

8. The Prolonged Analgesic Efficacy of an Ultrasound-Guided Single-Shot Adductor Canal Block in Patients Undergoing Total Knee Arthroplasty. (PubMed)

The Prolonged Analgesic Efficacy of an Ultrasound-Guided Single-Shot Adductor Canal Block in Patients Undergoing Total Knee Arthroplasty. In this prospective, randomized, placebo-controlled study, the authors compared the analgesic efficacy of the single-shot adductor canal block (SS-ACB) vs the continuous adductor canal block (C-ACB) with intermittent boluses during the 72-hour postoperative period. Seventy-five patients randomly received the following: a single shot of 20 mL of 0.5 (...) satisfaction with their pain-relief treatment. Given the similar analgesic effect but better quadriceps muscle strength, easier execution, and higher patient satisfaction, the SS-ACB may be more suitable for total knee arthroplasty patients than the C-ACB.

11. Ultrasound and anatomical study of accessing the nerves in the knee by fascial planes. (PubMed)

Ultrasound and anatomical study of accessing the nerves in the knee by fascial planes. The fascia is an undifferentiated mesenchymal tissue related to the peripheral nerves. Both can be identified by ultrasound, which is useful to perform peripheral nerve blocks. However, there is no unanimity about the approaching point of each nerve nor is there a consensus on how to name the appropriate infiltration zone, although the paraneural zone is frequently mentioned. The aims of this study (...) is to determine if ultrasound is accurate to identify the fascial planes and the paraneural space of the nerves in the knee, infiltrate them and achieve a correct anatomical diffusion, as well as establish access routes to avoid intraneural infiltration. The study was performed in 16 cryopreserved lower extremities of the dissection room of the Faculty of Medicine and Health Sciences. Nerves of the knee were injected with colourant guided by ultrasound after they were visualized. Correct location

Editorial Commentary: Ultrasound Barely Beats Magnetic Resonance Imaging in Knee Anterolateral Ligament Evaluation…But Does This Change the Treatment of the Anterior Cruciate Ligament-Deficient Knee? Ultrasound (US) examination of the anterolateral ligament (ALL) in the anterior cruciate ligament-deficient knee betters magnetic resonance imaging analysis with slightly higher identification rate of the entire ALL presumably due to the ability to test in a functional pivot shift configuration (...) . The ALL was injured in 63% of the anterior cruciate ligament-deficient knees and the injury occurred at the tibial insertion in all cases. Although the authors propose US to be the new "gold standard" for diagnosing ALL injuries, there still remains a question of whether there is any necessity for an US diagnosis of ALL injury when the pivot shift test may provide the necessary information, and the consensus for ALL reconstruction or lateral extra-articular tenodesis has yet to be reached.Copyright ©

Comparison of Diagnostic Performance of Semi-Quantitative Knee Ultrasound and Knee Radiography with MRI: Oulu Knee Osteoarthritis Study Osteoarthritis (OA) is a common degenerative musculoskeletal disease highly prevalent in aging societies worldwide. Traditionally, knee OA is diagnosed using conventional radiography. However, structural changes of articular cartilage or menisci cannot be directly evaluated using this method. On the other hand, ultrasound is a promising tool able to provide (...) direct information on soft tissue degeneration. The aim of our study was to systematically determine the site-specific diagnostic performance of semi-quantitative ultrasound grading of knee femoral articular cartilage, osteophytes and meniscal extrusion, and of radiographic assessment of joint space narrowing and osteophytes, using MRI as a reference standard. Eighty asymptomatic and 79 symptomatic subjects with mean age of 57.7 years were included in the study. Ultrasound performed best

20. Tibial artery duplex ultrasound-derived peak systolic velocities may be an objective performance measure after above-knee endovascular therapy for arterial stenosis. (PubMed)

Tibial artery duplex ultrasound-derived peak systolic velocities may be an objective performance measure after above-knee endovascular therapy for arterial stenosis. The ankle-brachial index (ABI) is a well-established measure of distal perfusion in lower extremity ischemia; however, the ABI is of limited value in patients with noncompressible lower extremity arteries. We sought to demonstrate whether duplex ultrasound-determined tibial artery velocities can be used as an alternative to ABI (...) as an objective performance measure after endovascular treatment of above-knee arterial stenosis.Thirty-six patients undergoing above-knee endovascular intervention had preprocedure and postprocedure duplex ultrasound examination within 6 months of intervention. Preprocedure vs postprocedure changes in tibial artery mean peak systolic velocity (PSV; mean of proximal, mid, and distal velocities) were compared with changes in ABI and a reference (control) cohort of 68 patients without peripheral vascular
