The purpose of this study is to compare two biologic methods for the treatment of articular cartilage defects in the knee. The first method, microfracture, is the standard of care and is routinely used to recruit cells from the subchondral bone marrow to the site of cartilage loss. The second method is the application of adipose-derived stem cells (ADSCs) to the defect site. In theory, ADSCs on a collagen scaffold should enable the delivery of more specific progenitor cells to the site of injury, resulting in better regeneration and integration of articular cartilage at the site of a defect as compared to the microfracture method.

Our purpose is to expand upon the results of the pilot study performed at David Grant Medical Center (DGMC) which showed that concomitant non-steroidal NSAID use in adults with knee osteoarthritis (OA) undergoing a three-shot dextrose prolotherapy (DPT) injection series did not negate the efficacy of DPT. Additionally, it showed that giving both treatments simultaneously is safe and efficacious. The small sample size and design of the pilot study limited the conclusions that can be drawn on the concomitant use of non-steroidal anti-inflammatory drugs (NSAIDs) during DPT treatment. This is a double-blinded, randomized, controlled trial that includes a subject population of males and females between the ages of 45-75 years who are DoD beneficiaries empaneled at DGMC with a history of chronic, symptomatic knee osteoarthritis in one or both knees, that meet study criteria. Participants will have study inclusion/exclusion and knee films (within the past 2 years) reviewed by a study investigator to confirm eligibility to participate in the study. Eligible participants will be consented then randomized into treatment groups (ibuprofen, placebo) by the pharmacy. Participants will provide a baseline assessment of pain and dysfunction using the Numeric Pain Rating Scale (NPRS) and Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaires. Participants will then have a series of three injections of 4mL of 25% dextrose mixed with 1% lidocaine into the knee under ultrasound guidance, performed at 0, 4 and 8 weeks (+/- 1 week) in addition to a 7-day supply of the study drug (ibuprofen, placebo) at these time points. NPRS and KOOS scores will be collected at 0, 4, 8 and 12 weeks. During the study period, participants will be counseled to avoid oral analgesics (other than what has been prescribed for them as part of the study) including NSAIDs, acetaminophen, or opioids, in addition to other procedures to treat their knee pain to include other injections, acupuncture, physical therapy, and surgery. The primary outcome is to determine the effect of concomitant oral ibuprofen vs. placebo use on intra-articular knee injections using hypertonic dextrose and the determine the short and long-term outcomes in each treatment group (ibuprofen, placebo) using the NPRS and KOOS questionnaires to assess pain and function.

Cooled radiofrequency ablation (cRFA) of the knee geniculate nerves is a promising treatment option for knee osteoarthritis, but has variable efficacy. Fluoroscopy is the typical guidance of choice, but uses bony landmarks to target these nerves which have variable positions around the knee. Alternatively, ultrasound allows for targeting based on visualization of bony landmarks, the nerves, and their accompanying vascular structures, and thus may offer greater accuracy. However, there are few studies which directly compare the clinical efficacy of these two guidance options. This study will compare these two options.

This study aims to investigate factors that affect the subjective experience of pain during and after intra-articular knee joint injection of steroids by comparing needle gauge size (22 G vs 25 G needles), as well as the presence or absence of topical ethyl chloride spray. Additionally, this study will investigate the effects of other various factors on patients' pain associated with the injection. Lastly, this study aims to determine the effect of patients' subjective pain from the injection on long-term clinical outcomes. Specific aims are as follows: Aim 1): Determine the effect of needle gauge size on patient reported pain associated with an ultrasound-guided intra-articular knee injection. Aim 2): Determine the effect of ethyl chloride spray on patient reported pain associated with an ultrasound-guided intra-articular knee injection. Aim 3): Determine the effect of sex, age, BMI, thigh size, severity of OA, and fear of needles on patient pain associated with an ultrasound-guided intra-articular knee injection. Aim 4) Determine the effect of patient pain from the procedure on longer term clinical outcomes after an ultrasound-guided intra-articular knee steroid injection. Researchers will obtain data at various time points, including pre-procedural data, immediately after the procedure, 24-48 hours after, and 6 weeks post-procedure. Participants will: Consent to receiving an intra-articular knee joint injection with steroids if indicated. Score their "procedural" pain immediately following the procedure, score their post-procedural "soreness" 24-48 hours after via telephone call, and score their overall knee pain about 6 weeks after the procedure via telephone call.

The purpose of this clinical trial is to determine whether genicular artery embolization (GAE) is an effective way to treat knee pain from osteoarthritis. Pain from arthritis is often due to underlying inflammation in the joint. The inflammation is associated with increased abnormal blood flow going to the specific area of pain. If the investigator can reduce the blood flow, the inflammation can be reduced and the pain can be controlled. The GAE procedure is an experimental procedure to decrease the blood flow (embolize) to the specific region of the knee that is causing the pain. This will be done by infusing microscopic spheres into the specific blood vessel (genicular artery) supplying the area of pain in the knee. This is done through a procedure which is called an angiogram, which is done entirely through a pinhole at the creased of the thigh, using twilight (conscious) sedation. The investigators have already completed an initial trial at UCLA, and shown that this procedure is safe and effective. The purpose of this new trial is to compare outcomes of people undergoing the GAE procedure to those who do not undergo the procedure. A total of 100 patients will be enrolled, and 2/3 of the patients will be randomly selected to undergo the GAE procedure. 1/3 will not undergo the procedure. This is known as a randomized trial. During the trial, all subjects will also get MRIs and fluid withdrawn from their knee joints at various timepoints in order to precisely figure out how the procedure works on a closer (microscopic) level.

Frequently Asked Questions

How much do Osteoarthritis Knee clinical trials in San Francisco, CA pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Osteoarthritis Knee clinical trials in San Francisco, CA work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Osteoarthritis Knee trials in San Francisco, CA 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length in San Francisco, CA for Osteoarthritis Knee is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility in San Francisco, CA several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Osteoarthritis Knee medical study in San Francisco, CA ?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Osteoarthritis Knee clinical trials in San Francisco, CA ?

Most recently, we added rTMS + Tai Chi for Osteoarthritis, Gait Retraining for Knee Osteoarthritis and TPX-100 for Knee Arthritis to the Power online platform.
