Primary synovial osteochondromatosis is a rare disorder and its diagnosis remains a challenge to the physician. We present the case of 36 year old patient with right knee monoarthritis in which ultrasound findings, corroborated with clinical and histopathological evidence confirmed the diagnosis of unossified primary synovial osteochondromatosis. The arthroscopy with synovectomy found multiple intra-articular loose bodies occupying the entire joint. The ultrasonographic findings were extensively evaluated.

Unilateral lower extremity edema below the knee commonly results from deep venous thrombosis, venous insufficiency, or lymphedema. The patient history, a physical examination, and lower extremity venous duplex ultrasound often reveal the underlying etiology, which is frequently of vascular origin. Presently described is the case of a 23-year-old patient who underwent a diagnostic workup for unilateral leg swelling and was found to have a relatively uncommon cause of edema: lipedema. Lipedema is a disease characterized by subcutaneous adipose tissue deposition, and although diagnosed very rarely in general cardiology outpatient clinics, it has been demonstrated to be a cause of lower extremity edema in approximately one-fifth of cases in specialized clinics...

Hip and groin pain often presents a diagnostic and therapeutic challenge. The differential diagnosis is extensive, comprising intra-articular and extra-articular pathology and referred pain from lumbar spine, knee and elsewhere in the pelvis. Various ultrasound-guided techniques have been described in the hip and groin region for diagnostic and therapeutic purposes. Ultrasound has many advantages over other imaging modalities, including portability, lack of ionising radiation and real-time visualisation of soft tissues and neurovascular structures...

OBJECTIVES: Ultrasound (US) is increasingly being used as an extension of the physical examination on the sidelines, in training rooms, and in clinics. Anterior cruciate ligament (ACL) injury in sport is common, but the literature on US findings after acute ACL rupture is limited. Three indirect US findings of ACL rupture have been described, and this study assessed the validity of these indirect signs. METHODS: Patients with an acute knee injury (<6 weeks) underwent US examinations to determine whether there was evidence of a femoral notch sign, posterior cruciate ligament wave sign, or capsular protrusion sign...

NEW FINDINGS: What is the central question of this study? Increased respiratory muscle activation is associated with neural and cardiovascular consequences via the respiratory muscle metaboreflex. Does increased sympathetic vasoconstriction originating from the respiratory musculature elicit a reduction in blood flow to an inactive limb in order to maintain blood flow to an active limb? What is the main finding and its importance? Arm blood flow was reduced while leg blood flow was preserved during mild leg exercise with inspiratory resistance...

PURPOSE: There has been no specific study on the quantitative morphological changes that occur in the infrapatellar fat pad (IPFP) after anterior cruciate ligament (ACL) reconstruction. We used ultrasonography to evaluate the dynamics of the IPFP in knees after ACL reconstruction using the contralateral knees as controls. METHODS: We enrolled 31 patients 3 months after they underwent ACL reconstruction. The thickness of the superficial part of the IPFP was measured using longitudinally oriented ultrasound images of the anterior part of both knees at 90° and 10° flexion...

This paper evaluates experiments on the knee using a new heating rehabilitation system. For effective thermal rehabilitation of osteoarthritis, it is necessary to heat the deep tissue inside the knee joint. Our new rehabilitation system is based on the re-entrant type resonant cavity applicator which was developed for deep hyperthermia treatment in our previous studies. Our experimental results using agar phantoms showed our heating system is able to heat the deep tissue inside the knee without physically contacting the surface skin...

People with knee osteoarthritis have atrophy of the muscles surrounding the knee joint. Therefore, exercise programs primarily have been focused on the strengthening of quadriceps femoris muscle (QFM). Primary aim of this systematic review was to determine which exercise increases strength of the QFM and describe the details of the training programs. Secondary aim was to determine effectiveness of strengthening of the QFM alone on pain and dysfunction in patient with knee osteoarthritis. PubMed, PEDro, and Cochrane were searched...

INTRODUCTION: The patella is a sesamoid for the quadriceps, which increases its power during knee extension and thus transfers considerable forces. The etiology of patellofemoral pain is multifactorial. In the absence of injury, the commonly accepted hypothesis is associated with increased compression of articulating surfaces. AIM: The aim of the study was to perform an ultrasound evaluation of the thickness of articular cartilage covering the medial and lateral femoral condyle in patients with an increased Q-angle...
