Ultrasonic echo intensity (EI), an easy-to-use measure of intramuscular fat and fibrous tissues, is known to increase with aging. However, age-related changes in EI have not been examined in a longitudinal design. The objective of this study was to investigate 4-year longitudinal changes in the EI of the quadriceps femoris in older adults, based on difference in physical activity (PA). This study included 131 community-dwelling older adults with a mean age of 72.9 {plus minus} 5.2 years. Subcutaneous fat thickness (FT), muscle thickness (MT), and EI of the quadriceps femoris were measured by ultrasound...

This article determines compartment opening of the medial articular space of the knee after pie crust (PC) technique of the medial collateral ligament (MCL) by ultrasound measurements and anatomic dissection. This is a cadaveric study of 12 specimens. Four anatomic references were marked on the skin. Distances between the femur and tibia in the internal compartment at 30 degrees of flexion were obtained with ultrasound measurements in four situations: with and without applying valgus force both prior and after the PC technique...

PURPOSE: To assess the stiffness of hamstring muscles during isometric contractions in healthy individuals, using ultrasound-based shear wave elastography to (1) determine the intra- and inter-day assessment repeatability, (2) characterize the stiffness of semitendinosus (ST) and biceps femoris long head (BFlh) along the contraction intensity, and (3) characterize stiffness distribution among the hamstring muscles and inter-limb symmetry. METHODS: Two experiments were conducted...

Background: Osteoarthritis (OA) is a common degeneration disease characterized with joint pain. The aim of the present study was to systemically review the effects of LIPUS on pain relief and functional recovery in patients with knee osteoarthritis (OA). Methods: PubMed, Embase, and Cochrane Library were searched manually for researches on LIPUS treatment in patients with knee OA from 1945 to July 2017. Two investigators independently selected the studies according to the inclusion and exclusion criteria, extracted the concerned data, and assessed the included studies...

Background and Aims: Adductor canal block (ACB) is now an established component of multimodal analgesia for knee replacement surgery and is slowly replacing femoral nerve block (FNB). It is also gaining popularity for providing pain relief in knee arthroscopies including anterior cruciate ligament reconstruction surgery (ACLR). Data is lacking from the Indian subcontinent on comparing ACB to the traditional FNB for ACLR. Hence, we conducted the present study to compare ACB and FNB in ACLR under general anesthesia...

Background: Psoas sciatic block (Pso/Sci) is a modern anesthetic technique for lower extremities surgery. The use of this technique can avoid the adverse effects of the general anesthesia or the central neuroaxial blockade, especially in patients with multiple comorbidities. Purpose: The purpose of this study is to compare the efficacy of combined Pso/sci as a sole anesthetic technique with conventional combined spinal epidural (CSE) anesthesia for patients undergoing total knee arthroplasty...

Maximizing analgesia is critical following joint arthroplasty because postoperative pain is a major barrier to adequate physical therapy. Continuous peripheral nerve blocks have been the mainstay for acute pain management in this population; however, this and similar techniques are limited by their duration of action. Cryoneurolysis and peripheral nerve stimulation are two methodologies used for decades to treat chronic pain. With the advent of portable ultrasound devices and percutaneous administration equipment, both procedures may now be suitable for treatment of acute pain...

INTRODUCTION: Osteoarthritis (OA) is the most common form of arthritis. Medical and surgical treatments have yet to substantially diminish the global health and economic burden of OA. Due to recent advances in clinical imaging, including magnetic resonance imaging (MRI), a correlation has been established between structural joint damage and OA-related pain and disability. Existing preclinical animal models of OA are useful tools but each suffers specific roadblocks when translating structural MRI data to humans...

BACKGROUND: Dexamethasone improves the quality and duration of peripheral nerve block when used as an adjuvant to local anesthetic. We evaluated the effect of adding dexamethasone to bupivacaine on the duration of postoperative analgesia in patients undergoing knee arthroscopy using ultrasound guided adductor canal block. METHODS: The study was a randomized, double-blinded, trial. Sixty patients scheduled for arthroscopic anterior cruciate ligament reconstruction were randomly allocated into two groups to receive adductor canal block...

Tendinopathy includes cases with chronic tendon pain and spontaneous tendon ruptures, which is putatively resulted from failed tendon healing. Overuse is a major risk factor of tendinopathy, which can impose mechanical and oxidative stress to tendons. Previous studies investigated the influences of mechanical stress, but the direct impact of oxidative stress on tendon healing remains unclear. We hypothesized that imposed oxidative stress can impair tendon healing and lead to tendinopathic changes. Thirty-nine rats were operated for patellar tendon window injury...

Introduction: The knee arthroplasty is the best option for patients with advanced osteoarthritis who have failed all other conservative options, but regrettably many patients fail to undergo surgery due to co-morbidities or other reasons. So, new alternative modes are always in demand for these patients. Methods: The ultrasound-guided radiofrequency ablation (RFA) of all the genicular nerves of knee joint was done in patients with grade III and IV osteoarthritis of knee joint, with severe pain (numerical rating scale (NRS) > 7) who had failed conservative management and intra-articular injections after a positive genicular nerve block with local anaesthetics...

It can be difficult to diagnose a tibial avulsion fracture based on physical examination alone as findings are often non-specific. Emergency physicians will usually opt for radiography as their initial imaging modality, which has several disadvantages in evaluating tibial avulsion fractures. The objective of this case series is to describe the utility of point-of-care ultrasound (POCUS) in the evaluation of tibial avulsion injuries. A 15-year-old male presented to the emergency department (ED) after sustaining a left knee injury while playing soccer...

BACKGROUND AND OBJECTIVES: The lateral and anterior approaches for proximal sciatic nerve (SN) block can be used in patients lying supine. We assume that the posterior femoral cutaneous nerve (PFCN) is simultaneously blocked more often via the lateral approach than via the anterior approach, given the proximity of these 2 nerves at the injection level. However, locating the SN is difficult when using the original landmark-based lateral approach. We have introduced ultrasound guidance to alleviate the technical difficulty of the lateral approach and tested the hypothesis that an ultrasound-guided lateral approach would achieve PFCN block more often than the ultrasound-guided anterior approach for SN block...

BACKGROUND: Color and power doppler ultrasound are commonly used in the evaluation of ovarian torsion but are unreliable. Because normal sized ovaries are unlikely to cause torsion, maximum ovarian diameter (MOD) could theoretically be used as a screening test in the ED. Identification of MOD values below which torsion is unlikely would be of benefit to providers interpreting radiology department or point-of care pelvic ultrasound. OBJECTIVES: To determine if sonographic maximum ovarian diameter (MOD) can be used as a screening tool to rule out torsion in selected patients...

BACKGROUND: Blood loss and deep vein thrombosis (DVT) are important complications after total knee arthroplasty (TKA). Topical tranexamic acid (TXA) effectively reduces wound bleeding but may elevate the risk of DVT. In contrast, rivaroxaban potently prevents DVT but has been associated with bleeding complications. The simultaneous use of topical TXA and rivaroxaban in TKA has not been much investigated. METHODS: A retrospective cohort study was conducted with two consecutive groups of patients who underwent TKA...
