Exparel Anesthetic for Total Knee Replacement
Cleveland, Ohio
Intra-articular Posteromedial Surgeon Administered (IPSA) Block in this study describes a new type of medical procedure where a surgeon provides anesthetic medication directly into a specific area inside a knee joint to numb the pain during knee surgery. Intra-articular refers to inside of knee joint, posteromedial refers to the back and inner side of a knee joint, and surgeon administered means a surgeon is performing the procedure.
Patients You will be randomly assigned to one of these three treatment groups:
Group 1:
Patients in this group will receive IPSA block and Local Infiltration Analgesia (LIA).
IPSA block is a pain numbing medication given by surgeon and injected inside the back and inner side of the knee joint. Local Infiltration Analgesia is a pain numbing medication injection given by the surgeon around the surgical knee area. The medications used in the procedure will be EXPAREL, and Bupivacaine HCL.
Group 2 (Control):
Patients in this group will receive Adductor Canal Block (ACB) and Local Infiltration Analgesia (LIA). ACB is a pain numbing injection given by anesthesiologist near the adductor canal, a passage in the mid-thigh that contains nerves connecting the knee region. Local Infiltration Analgesia is a pain numbing medication injection given by the surgeon around the surgical knee area. The medications used in the procedure will be EXPAREL, and Bupivacaine HCL.
Group 3:
Patients in this group will receive Local Infiltration Analgesia (LIA). Local Infiltration Analgesia is a pain numbing medication injection given by the surgeon around the surgical knee area. The medications used in the procedure will be EXPAREL, and Bupivacaine HCL.
The study will evaluate;
* How effective the pain relief is after surgery.
* How much extra pain medication you need.
* Your satisfaction with pain management and recovery
* Any side effects.

Total knee replacement (TKR) is a common and costly procedure widely used to relieve pain and improve function in patients with symptomatic advanced knee osteoarthritis (OA). As of 2013, the annual incidence of TKR was over 680,000 surgeries and annual costs exceeded $11 billion. Growing evidence suggests that while pain and functional status improve following TKR, physical activity (PA) typically does not surpass pre-TKR levels. Engagement in PA can meaningfully improve quality of life (QoL), pain, and function. Given the large investment in TKR, the effectiveness and cost-effectiveness of TKR could be substantially increased if TKR recipients became more physically active.
The Knee Arthroplasty Activity Trial (KArAT) is a randomized controlled trial and participants will be randomly assigned to one of three arms. Participants across all arms will receive usual post-operative care for TKR surgery. Participants in the first arm will complete basic study activities, such as responding to surveys and attending two in-person clinic visits. Participants in the second arm will do the same and also receive a wrist-based physical activity tracker intervention. Participants in the third arm will receive a telephonic active coaching (motivational interviewing) and financial incentives (for reaching physical activity goals) (TAC(MI)+FI) based intervention, as well as a wrist-based physical activity tracker intervention. The second and third arms will be eligible to receive lottery-based financial rewards for wearing a wrist-worn activity tracker for twenty-four months during the study.

Knee Surgery vs Physical Therapy for Osteoarthritis
Cleveland, Ohio
There are two cartilage structures, called menisci, in each knee joint. A torn meniscus can be caused by a traumatic injury or aging-related degeneration. Osteoarthritis (OA) is a type of arthritis that is caused by the breakdown and eventual loss of another type of cartilage that covers the end of bones within a joint. In people who have knee OA, a meniscal tear can easily lead to disability. This study will compare the effectiveness of two recommended treatments, surgery and physical therapy, for people with a torn meniscus and knee OA.

Coated vs. Standard Knee Implants for Osteoarthritis
London, Ontario
Metal hypersensitivity is a recognized complication in some patients following total joint arthroplasty. This can result in a reaction to metal particles from the implants placed in the joint and cause tissue injury. The Evolution® NitrX™ (MicroPort Orthopaedics, Memphis, TN) knee implant was designed with the addition of a coating meant to create a barrier against the release of metal ions. The primary purpose of this study is to compare the Evolution and Evolution NitrX implant (implants your surgeon uses in total knee arthroplasty surgery). This study will compare the stability of these knee implants (any movement the implant makes after surgery) through the use of specialized xrays, called "radiostereometric analysis" (RSA for short). The investigators will also compare levels of circulating metal particles with blood draws and the effects of any circulating metal with MR imaging. The investigators will also be looking at the participants clinical outcomes using joint function and patient satisfaction questionnaires. A total of 50 patients will be enrolled into the study.

Probiotics for Knee Replacement
London, Ontario
Patients having knee replacement surgery regularly experience joint pain and compromised bone quality leading to implant loosening and periprosthetic fractures. The role of the gut microbiome, which is the collection of bacteria and other microbes within the human gastrointestinal tract, is just beginning to be recognized, including its potential effects on pain, infection, and loosening after total joint replacement. Antibiotics are regularly used in orthopaedic surgery to reduce the risk of infection, but they also harm gut microbiota and reduce their potentially beneficial effects. Probiotics may have a role to play in enhancing bone quality and decreasing synovial inflammation after joint replacement surgery, and this study will explore the potential relationship of probiotic use with implant migration, bone density, and patient outcomes.
This study is a randomized, controlled, double-blinded trial comparing probiotic use with placebo in post-menopausal women undergoing primary total knee replacement. The main questions it aims to answer are:
* to compare implant migration between groups from baseline to six weeks post-surgery
* to compare bone density and joint inflammation between groups from baseline to six weeks post-surgery
* to compare gut microbiome composition and patient-reported outcome measures between groups from baseline to six weeks post-surgery

Morphine + Vancomycin for Pain Control After Knee Replacement
Roanoke, Virginia
Study investigators propose to investigate if a bony injection of pain medication during a knee replacement will help pain levels following primary knee replacement surgery. To investigate this, 86 patients will be enrolled. Half of the patients will receive a bony injection of antibiotics with morphine (pain medication) while the other half will receive a bony injection of antibiotics with placebo (no pain medication). Following surgery, patient pain levels and pain medication consumption will be measured.
The injection is intraosseous meaning in the bone. The needle pierces the bone and the medication is injected into the bone. The site of injection is on the anterior (front) of the upper portion of the tibia. The medications are Vancomycin (antibiotic) and Morphine (pain medication) which are mixed in separate syringes and then injected. Intraosseous vancomycin is standard of care while intraosseous vancomycin with morphine is also standard of care, depending on operating surgeon.

Articulating Spacers for Knee Infections
Chicago, Illinois
In the US, if an infection in an artificial knee joint doesn't heal with antibiotics alone, the standard treatment is a two-stage revision of the artificial knee. In the first stage, the surgeon will remove the artificial knee and clean out the area around the knee. They will then place an antibiotic spacer. An antibiotic spacer is a type of artificial joint that will release antibiotics into the knee space continuously over time. The spacer allows only very basic function of the knee. The patient may need to use crutches or a walker while the antibiotic spacer is in place. After surgery to place the antibiotic spacer, the surgeon may prescribe a course of antibiotics as well. Because the antibiotic spacer is not as durable as a regular artificial joint, after the infection is gone, another surgery is required to take the spacer out and put a new artificial knee joint in.
There is another way for artificial joint infections to be treated. This is a one-stage revision. In this treatment, the surgeon will remove the artificial knee and clean out the area around the knee. Then the surgeon will place a new artificial knee in using a special kind of cement that contains antibiotics. The cement will release antibiotics into the knee space continuously over time (the surgeon may prescribe a course of antibiotics as well). The new artificial joint with antibiotic cement will function almost the same as the original artificial knee. This means that while the infection is healing the patient will be able to do most of the regular daily activities. However, the antibiotic cement is not as durable as what is normally used to implant an artificial knee. The artificial knee with the antibiotic cement may need to be replaced with a regular artificial knee. When replacement will need to be done is dependent on patient weight, bone strength and activity level, among other things. When it is time to replace the antibiotic cement artificial knee, the patient will have another surgery where the surgeon will take the antibiotic cement artificial knee and put a new artificial knee joint in.
Investigators know that both the one- and two-stage revision work equally well to heal the infection, but investigators don't know which patients prefer or which provides better function after many years. This study will randomly assign patients to receive either a one-stage or two-stage revision and then follow them for 5 years to ask them about pain, function, and satisfaction.

Treadmill Training for Fall Prevention After Knee Replacement
Chicago, Illinois
The goal of this clinical trial is to learn about preventing falls in people who have total knee replacement surgery using treadmill perturbation training. Perturbation training involves adjusting to rapid speed changes on a treadmill. The main questions it aims to answer are:
* Does perturbation training improve the way that people who are planning to have total knee replacement surgery recover after treadmill test that reproduces a trip to the front or side?
* Does perturbation training reduce the incidence of preventable gait-related falls during the first year after total knee replacement?
Participants will:
* complete surveys about their condition and fall history and take part in testing of walking ability and balance.
* have a baseline gait analysis test to measure the motion of their body during normal walking.
* Be randomized into two groups. One will receive fall-prevention literature. The other will receive the same literature and then take part in a two-week treadmill perturbation training program.
* be contacted every two weeks for one year, and asked questions about whether they have fallen during that time.
* wear a Fitbit activity monitor on their wrist for one year. Researchers will compare the number of falls from the group that only received literature to the treatment group to see if the training group has fewer falls during the year after surgery.

Knee Replacement Techniques for Osteoarthritis
Hamilton, Ontario
Knee replacement surgery is the second most common surgery in Canada. People who have very painful knee arthritis usually receive a knee replacement where the surgeon aims to make everyone's knee as straight as possible (called mechanical alignment). Mechanical alignment focuses on making the implant last as long as possible. However, everybody's knee shape is different and we think that it is important to take individual differences into account. A newer technique that is more personalized is called restricted kinematic alignment. This technique customizes the placement of the new knee to reproduce each patient's unique knee shape, which may not be perfectly straight. We think this newer technique may feel more natural, be more stable, and lead to better knee function. Restricted kinematic alignment might last as long or longer than mechanical alignment, but the research that has been conducted to date is not clear. We are conducting this study to help surgeons better understand which technique is better. One of the reasons the existing research is not clear is because new developments in robotic technology now allow surgeons to place knee implants very precisely, which was not done in most previous research. In this study everyone will receive a robot-assisted knee surgery so we can be sure the implants are placed as precisely as possible.
The purpose of this trial is to determine whether there are differences in patient outcomes using restricted kinematic alignment rather than the traditionally used mechanical alignment for total knee replacements.
Participants who are having total knee replacements will be randomized to receive either a robot-assisted total knee replacement using mechanical alignment, or a robot-assisted total knee replacement using restricted kinematic alignment . We will ask participants to walk in a markerless motion capture system which will measure walking characteristics at pre-op, 6 months postop and 12 months postop. Participants will also complete a series of standardized questionnaires at preop and 6 months, 12 months, and 24 month postop.

Multiprofen-CC™ for Postoperative Pain
Hamilton, Ontario
Total knee arthroplasty is a surgical treatment which involves replacing the damaged articular cartilage of the knee joint with an artificial prosthetic in end-stage knee osteoarthritis. Although total knee arthroplasties are mostly successful, approximately 1 in 5 patients are unsatisfied with their outcomes with 16-33% of patients of patients experiencing lasting pain following total knee arthroplasty.
Multiprofen-CC™ is a compounded topical analgesic currently available to healthcare professionals for prescription in patients experiencing localized musculoskeletal pain. To date there has been no evidence-based guidance generated to evaluate the efficacy of Multiprofen-CC™ in osteoarthritis patients. This study will test, in patients with end-stage knee osteoarthritis undergoing total knee arthroplasty, if the use of topical Multiprofen-CC™ in addition to standard of care pain management is more effective in controlling knee pain and reducing opioid use compared to placebo plus standard care alone.

Frequently Asked Questions
How much do Knee Replacement clinical trials 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 Knee Replacement clinical trials 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 Knee Replacement trials 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 for Knee Replacement 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 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 Knee Replacement medical study?
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 Knee Replacement clinical trials?
Most recently, we added Smart Knee Implants for Osteoarthritis, Nurse Navigator Program for High-Risk Hospital Patients and Exparel Anesthetic for Total Knee Replacement to the Power online platform.
