Alpha-Defensin and Synovial Proteins to Improve Detection of Pediatric Septic Arthritis
Differentiating between septic arthritis and other causes of joint inflammation in pediatric patients is challenging and of the utmost importance because septic arthritis requires surgical debridement as part of the treatment regimen. The current gold standard to diagnose septic arthritis in children is a positive synovial fluid culture; however, joint cultures may take several days to return. If a bacterial infection is present, it requires immediate surgical intervention in order to prevent lasting articular cartilage damage. Frequently surgeons must decide whether to surgically debride a joint before culture results are available. There...
Alterations in Muscle After Total Knee Arthroplasty
The overall goals of this work are: 1) to elucidate alterations in gene expression and downstream protein synthesis 2 weeks after Total Knee Arthroplasty (TKA) to better explain quadriceps muscle atrophy after TKA and 2) understand the mechanisms responsible for improved maintenance of muscle strength with Neuromuscular Electrical Stimulation (NMES) utilization. Furthermore, this investigation seeks to expand previous findings regarding attenuation of strength and functional performance deficits with NMES application to better understand how altered gene expression influences muscle function.
AMG0103 in Subjects With Chronic Discogenic Lumbar Back Pain
This clinical trial evaluate the safety, tolerability and exploratory efficacy of targeted single injection of AMG0103 in subject with chronic discogenic lumbar back pain
Amnion-Based Injections in the Shoulder
Osteoarthritis (OA) of the shoulder is a common debilitating condition affecting up to 5% of the general population and as much as 32% of patients over 60 years of age. Clinically, OA is diagnosed by a combination of symptoms, such as slow onset of progressively worsening shoulder pain and stiffness over months to years (often with a history of minor trauma), and pain with activity. Physical exam may show tenderness and swelling, muscle atrophy, and decreased range of motion. Adhesive capsulitis (also called "Frozen Shoulder") is another common shoulder condition, affecting 2-5% of the general population. Frozen shoulder presents with a...
Amniotic Umbilical Cord Particulate During Total Knee Arthroplasty
Total knee arthroplasty (TKA) is the most common joint replacement surgery and its incidence is expected to increase 673% to 3.48 million procedures annually by 2030. After more than 20 years of follow-up data, TKA is confirmed to be an effective treatment for knee osteoarthritis, however, postoperative pain management continues to be a challenge despite advances in surgical techniques and anesthetic practice to minimize discomfort and enhance recovery. This acute post-surgical pain caused by extensive tissue damage and inflammation in TKA leads to restricted post-operative knee range of motion (ROM) and ability to mobilize.

A Multi-centre, Prospective Surveillance to Assess Mid-term Performance of the Mpact Cup
This is a multi-centre, prospective post marketing surveillance study to assess mid-term performance of the Mpact cup in subjects requiring primary total hip arthroplasty.
Anakinra in Infants and Children With Coronary Artery Abnormalities in Acute Kawasaki Disease
Kawasaki disease (KD) is the leading cause of acquired heart disease in children in the developed world. Despite available treatment, 25% of children in San Diego County appropriately treated for KD develop coronary artery abnormalities that may lead to complications later in life, including heart attack. Although the investigators can identify children with KD that have these coronary artery abnormalities, there is no approved additional treatment to decrease coronary artery inflammation and arrest or prevent damage to the coronary arteries. Anakinra, a therapy that blocks the high levels of interleukin 1 (IL1) that lead to inflammation...
Analgesic Effect of Music Listening During Pain Elicitation in Fibromyalgia
Patients with fibromyalgia (FM) are more sensitive to things that cause pain. Music lowers self-reported pain in patients with chronic pain. The investigators are able to measure pain sensitivity and pain tolerance using tools that cause pain and give accurate measurements of how much pressure is put on the body (QST). Previous studies have shown that after a few minutes of listening to music patients with FM have less self-reported pain, can get up and move from sitting more quickly, and have more activity in part of the brain that tells the body to stop sending pain signals. The investigators will study 40 patients with FM using the QST...
Analysis of a Tapered Porous Coated Stem and a Cementless Hemispherical Acetabular Component
This prospective study will evaluate the hip function and quality of life of patients operated for total hip arthroplasty with Masterloc femoral stem and MPACT acetabular cup. The results of this study will establish the performance of Masterloc femoral component (Medacta International SA) and MPACT acetabular component (Medacta International SA), and provide a general estimate of survivorship, clinical effectiveness and complications.
