Vitamin D and Fish Oil for Autoimmune Disease, Inflammation and Knee Pain

The VITamin D and OmegA-3 TriaL (VITAL; NCT 01169259) is a randomized clinical trial in 25,871 U.S. men and women investigating whether taking daily dietary supplements of vitamin D3 (2000 IU) or omega-3 fatty acids (Omacor® fish oil, 1 gram) reduces the risk of developing cancer, heart disease, and stroke in people who do not have a prior history of these illnesses. This ancillary study is being conducted among VITAL participants and will examine whether vitamin D or fish oil have effects upon A) autoimmune disease incidence, B) biomarkers of systemic inflammation, and C) chronic knee pain. Blood samples at baseline and in follow-up will be collected in a randomly selected subcohort of 1500 individuals and analyzed for changes in biomarkers of systemic inflammation: C-reactive protein, interleukin-6, and tumor necrosis factor-receptor 2. Approximately 1300 individuals with chronic, frequent knee pain will be followed with annual questionnaires to evaluate the effects of the supplements on chronic knee pain.

Prospective Functional, Gait, and Outcome Comparison Study of Medial Pivot Versus Single Radius Design for Total Knee Arthroplasty

Patients with degenerative joint disease can effectively be treated with a primary total knee replacement to reduce pain and improve function in their daily lives. Theoretically, achievement of normal knee motion using a medial pivot design in total knee replacements can be recreated in comparison to single radius designs, which could lead to an improvement in post-surgical outcomes and satisfaction with the procedure. The aim of this study is to compare two types of implant designs (medial pivot and single radius) in a total knee replacement using clinical outcomes, patient reported outcomes, and overall function assessed by a specialized gait laboratory.

Maladaptive Psychosocial Beliefs and Adolescents With Patellofemoral Pain

This is a randomized prospective study assessing the impact of psychosocial factors on pain and physical performance among adolescents with patellofemoral pain. A set of psychosocial surveys assessing fear avoidance beliefs, kinesiophobia, and pain catastrophizing will be completed by the participant/parents. Participants will then complete an activity questionnaire, numeric pain rating scale, and a self-report questionnaire of functional ability. Participants will then be randomized into one of two groups (psychologically informed education group and a control group). Participants will view a series of educational videos (based upon group assignment) and complete physical therapy exercises for lower extremity strengthening, flexibility, and neuromuscular control. Participants with patellofemoral pain will then complete follow-up surveys of their psychosocial beliefs, pain and self-reported functional ability through REDcap at immediately post-intervention, 1 week, 3 weeks, 6 weeks, and 3 months.

Adolescent Anterior Knee Pain: ARP Wave Therapy vs. Physical Therapy

Accelerated Recovery Performance (ARP) Wave therapy is an electromyostimulation therapy designed to enhance neuromuscular control in order to rehabilitate patients with musculoskeletal pathology. The outcomes of this technology have not been assessed under the rigors of clinical science. This prospective randomized crossover study will assess ARP Wave to both shorten duration of therapy and determine other advantages in the treatment of adolescent anterior knee pain. Two cohorts of teenagers will be followed weekly through either physical therapy (PT) or ARP Wave therapy, physiological therapy versus neurological therapy, respectively. Results should highlight the clinical utility of this modality and provide pilot data for future study.

Ultrasound-Guided Adductor Canal Block for Total Knee Arthroplasty Surgery

The ultrasound-guided selective blockade of the saphenous nerve in the adductor canal provides effective analgesia and reduces postoperative pain in patients undergoing arthroscopic medial meniscectomy. Selective blockade of the saphenous nerve in the adductor canal provides effective analgesia without quadriceps muscle weakness. It has been shown that the adductor canal block (ACB) block increases the spread of local anesthetics in a distal and proximal way. Therefore, the proximal spread of local anesthetics may cause possible quadriceps weakness. The distal spread of local anesthetics may increase analgesic effect via sciatic nerve. The different volumes for ACB is a topic of discussion. The aim of this study is to compare the different volumes of US-guided ACB performing for postoperative analgesia management after total knee arthroplasty surgery.

Can Simplified and More Detailed Instructions Affect Post-Operative Narcotic Consumption

This project intends to investigate whether (1) a patient-maintained opioid diary provides an accurate measure of opioid consumption (morphine equivalents), (2) improved patient educational materials decrease narcotic consumption, and (3) using a pain management counselor provides additional benefits in decreasing narcotic consumption when used in conjunction with improved educational materials. Furthermore, the investigators would like to investigate the effect of the patient-maintained diaries, the improved educational materials, and the pain management counselor on pain levels, nausea, sleep quality, and patient satisfaction. All patients undergoing orthopedic surgery at Brigham and Women's Faulkner Hospital and choose to participate will be assigned to a treatment group based on which arm of the study is being tested at the time; (the treatment arms are sequential). Members of Group 1 (control group) will receive the current standardized institutional discharge care for orthopedic surgery and an added tracking diary. Members of Group 2 (experimental group 1) will receive more detailed educational materials regarding postoperative pain management - including instructions to how to taper their narcotic usage - as well as a tracking diary. Members of Group 3 (experimental group 2) will receive not only the educational materials of Group 2, but also weekly phone calls from a clinical patient educator to remind them of proper use of the diary and narcotic tapering.

Molecular Pathways Involved in Knee Pain

Knee osteoarthritis (OA) is the most common form of arthritis and the most common cause of knee pain in the world. The rate of knee arthritis is as high as that of cardiac disease and is the most common problem in individuals over the age of 65. Central Sensitization (CS) is a marker of widespread pain sensitivity that can occur throughout the central nervous system distribution, leading to changes in the spinal cord as well as in the brain. The presence of CS increases the complexity of the clinical picture and can negatively affect treatment outcomes. CS is present in >20% of patients suffering from knee OA indicating that in the majority of individuals suffering with painful knee OA, knee pain should be related to molecular changes in the joint. CS might be also associated with discrete synovial fluid proteomic signatures due to the generation by the joint of chemical mediators (e.g. nerve growth factor) that drive CS, or CS might moderate the relationship between synovial fluid proteomic signatures and symptoms due to alterations in pain processing. The aim of this study is to explore the potential molecular links between pain and structure on knee pain using synovial fluid proteomics. A secondary purpose is to explore the association of knee pain with biomarkers of stress, metabolism and dietary habits. In a single session, ultrasound-guided synovial fluid, blood urine and saliva extraction, clinical assessment, completion of a questionnaire booklet and knee x-rays will be conducted. The clinical assessment will measure three features of central sensitisation (sensitivity to blunt pressure on the most painful knee, changes in pain felt during repeated light pricking of the knee skin, and reduction in pain that accompanies inflation of a blood pressure cuff on the non-dominant arm), features of leg strength (dynamometer, time up-and-go test) and features of balance (sway). Participant involvement at each session is expected to last less than 3 hours. Individuals over 45 having complaints of knee pain for 3-6 months are eligible to participate. The clinical assessments, questionnaire completion and subsequent statistical analysis are expected to be completed within 18 months of study commencement. The findings can provide more insight into the traits of knee pain, allow the examination of possible correlations to each other, and highlight potential detrimental effects of them on knee joint health.

Cognition, Pain and Wellbeing

Osteoarthritis (OA) is the most common form of arthritis and for 4 in 10 people pain from OA is not adequately controlled. The pain experience of people suffering from chronic pain largely depends on their individual perception of pain and on brain functions, in particular what is called "cognitive" functions. Cognitive functions include memory, attention, organisation and planning, task initiation, regulation of emotions and reflection of oneself and are important for everyday tasks, such as following a conversation or a story in a book or on TV, learning new things, remembering old and new information and making decisions. Good cognition predicts the risk of developing chronic pain after a painful event, such as surgery. Chronic pain patients report numerous cognitive impairments, with attention and memory being the two most prominent that can persist even after the original cause of pain has been treated. Little evidence exists regarding the nature and magnitude of these deficits and their underlying brain and psychological mechanisms in chronic knee OA. The investigators want to understand which cognitive functions and to what extent are associated with pain in patients with knee OA.
