We aimed to test the hypothesis that the magnitude of differences in muscle activation of the knee and hip extensor muscles between high-intensity interval exercise (HIE) and moderate-intensity constant exercise (CE) would be greater for the gluteus maximus than for the quadriceps femoris muscle. Participants were 11 male middle- or long-distance runners. The HIE (4 sets, 4-min induration, performed at 80-85%VO and followed by a 3-min period of cycling at < 30%VO) and CE (28-min, performed at or near 60%VO) were completed on different days, with the total exercise duration and work being identical for both protocols.

We present the case of an 81-year-old woman who was followed up by the Rheumatology Service for osteoporosis and treated with bisphosphonates for more than five years. She reported a fracture of the distal third of the contralateral femur by a low energy mechanism, treated with retrograde intramedullary nailing the previous year. She presented a clinic of cruralgia and left gonalgia, without previous trauma. Read More

Acta Ortop Mex 2018 May-Jun;32(3):157-162

Servicio de Cirugía Articular, Hospital Juárez de México, Ciudad de México.

Background: Reconstruction of the anterior cruciate ligament (ACL) aims to restore the original anatomy. The clinical outcome could be imperfect when graft placement is not in an anatomical position; moreover, the conventional transtibial reconstruction of the ACL often locates the graft away from the anatomical site, leading to abnormal biomechanical behavior and kinematics of the knee. The objective of this work was to assess the importance of the angular reconstruction of the anterior cruciate ligament during arthroscopic replacement and to compare the postoperative functional results.

Acta Ortop Mex 2018 May-Jun;32(3):134-139

Instituto Allende de Cirugía Reconstructiva de los Miembros, Córdoba-Argentina.

Background: The International Association for the Study of Pain (IASP) defines pain as an unpleasant sensory and emotional experience associated with actual or potential tissue damage. Total knee arthroplasty is one of the orthopedic surgeries that manifests more pain in the first 24-48 hours, needing a multimodal analgesic therapy. The objective of this work is to compare two different intravenous analgesic modes applied to patients undergoing a primary total knee arthroplasty, analyzing the quality of pain control, hospital stay and costs.

Hydrogen sulfide (HS) is found in both the plasma and synovial fluid of patients with gonarthrosis. In the present study, we investigated whether intra-articular injection of sodium hydrosulfide (NaSH) (1 mM, 30 μL), a HS donor, might affect gonarthrosis in rats. Gonarthrosis was induced surgically in the left knees of rats and left for 6 weeks for the development of disease. Read More

Kircher, Department of Small Animals, Division of Diagnostic Imaging, Vetsuisse Faculty, University of Zürich, Zürich, Switzerland.

Background: Biochemical MRI of hip cartilage such as delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) and T2 mapping is increasingly used to judge cartilage quality in the assessment of femoroacetabular impingement (FAI). The current evidence is sparse about which of these techniques yields a stronger correlation with histologic cartilage degeneration because of the difficulty in validating biochemical MRI techniques against histology in the clinical setting. Recently, an experimental ovine FAI model was established that induces chondrolabral damage and offers a validated platform to address these limitations. Read More

Introduction: The Kellgren-Lawrence (K-L) grade is the most commonly used measure of radiographic disease severity in knee osteoarthritis (OA). Studies suggest that intra-articular hyaluronic acid (IA-HA) should only be considered in cases of early stage knee OA. The purpose of this review was to determine if trials administering IA-HA in early-moderate knee OA patients demonstrated greater pain relief than studies that also included patients with end-stage disease.

Background: The tibial tuberosity-trochlear groove (TT-TG) distance is used to determine the necessity of tibial tubercle osteotomy. We conducted this study to determine the extent to which each of the tibial tuberosity lateralization, trochlear groove medialization, and knee rotation angle affects the TT-TG distance in both normal and patella dislocated patients and thereby scrutinize the rationale for tuberosity transfer based on the TT-TG distance.

Methods: Retrospective analysis of rotational profile computed tomography was done for patella dislocated and control group patients. Read More

Nail-patella syndrome (NPS) or hereditary onycho-osteodyaplasia is a rare genetic condition involving a mutation in the LMX1B gene affecting nails, elbows, knees, and pelvis. Due to the regulatory functions of the gene in many developmental processes through the body, patients with NPS experience wide-ranging musculoskeletal problems including patellar instability, fingernail anomalies, iliac exostoses/horns, and elbow abnormalities. The patellar changes often involve aplasia, hypoplasia, and chronic dislocation. Read More

Background: We report our clinical experience of a supraclavicular lymph node flap (LNF) using a novel method of harvesting based on the compartimental lymphatic and vascular anatomy of the right posterior neck triangle, which allows to harvest two independent LNFs from the same donor site.

Patients And Methods: We report a case series of 10 consecutive patients affected by cancer-related lower extremity lymphedema, who underwent compartimental dual LNF transfer from the right supraclavicular area to the affected lower limb, from August 2015 to March 2017. The superficial compartment flap (venous flap along the external jugular vein) was anastomosed in a flow-through fashion along the course of the great saphenous vein in the knee region, whereas the deep compartment flap (transverse cervical artery/vein flap) was anastomosed in an end-to-end fashion to the medial sural artery and comitantes vein.
