Background

Knee pain is a widespread health issue affecting a significant portion of the population worldwide. Over one fourth of individuals above the age of fifty experience knee pain, making it a common condition that impacts daily life and mobility. In the United Kingdom alone, nearly three million people suffer from knee pain annually, with common causes including damage to the cartilage, such as osteoarthritis, or injuries to the patella tendon, known as patella tendonitis.
While several physiotherapy treatments exist for knee pain, many are not self-applicable, limiting their accessibility and convenience for patients. Additionally, those self-applicable methods often lack high efficacy, leaving a gap in effective home-based treatment options.
In response to this need, innovative solutions like the Motive Health device have emerged. Motive Health, under the leadership of president and CEO Rob Morocco, has launched a direct-to-consumer product designed to provide lasting knee pain relief from home, marking a significant advancement in patient-centered care.
Regulatory pathways for such medical devices vary across regions, with CE-marking being a key prerequisite for approvals in many Middle Eastern and African countries. There are also ongoing discussions to accept US FDA approval or clearance in markets like Switzerland and the UK alongside CE-marking, reflecting the evolving landscape for medical device regulation and accessibility.

Description of the Device

The device is an implantable post-surgical kinematic measurement knee device that provides objective kinematic data following total knee arthroplasty surgery. It is classified by the FDA under class II with special controls codified in 21 CFR 888.3600 to ensure its safety and effectiveness. Designed to strengthen the quadriceps muscles and provide temporary symptomatic pain relief associated with knee arthritis, the device uses powered muscle stimulation through precise electrical pulses to treat knee pain.
Each unit comes paired with reusable therapy pads, a knee wrap, conductive gel, and a charging cable to facilitate its use. The electrical stimulation delivered by the device not only helps alleviate pain by potentially triggering a shift of electrical charge in pain neurons—a process called depolarization that can reset pain perception—but also aids muscle contraction. This stimulation can prevent muscle atrophy, a common complication resulting from disability or prolonged immobilization that may further damage knee components.
Originally developed as the Kneease device, which won the 2009 Schroders Award for Innovation, the technology has evolved into a more powerful and portable version. The device has been available in the UK and EU markets since 2010 and has been refined to be user-friendly, safe, and effective for many sufferers of knee pain.

Mechanism of Action

The device employs precise electrical pulses to stimulate muscle movement around the knee, specifically targeting the large muscle groups that support the joint. This muscle stimulation leads to increased strength in these muscles, which in turn alleviates pressure on the knee, resulting in reduced pain and improved mobility. Unlike traditional treatments such as braces, medications, or transcutaneous electrical nerve stimulation (TENS) devices that primarily offer temporary relief, this approach focuses on enhancing muscle strength, a key factor for long-term pain reduction.
In addition to strengthening muscles, the electrical stimulation may trigger depolarization in pain neurons within the brain, effectively resetting the perception of pain and providing prolonged relief. The muscle contractions induced by the device also help prevent muscle atrophy, a common complication resulting from disability and immobilization, which can exacerbate knee damage if left untreated.

Clinical Studies and Effectiveness

Electrical stimulation therapies have emerged as promising non-pharmaceutical and non-invasive alternatives for managing knee pain, particularly in chronic or degenerative conditions where traditional options are limited to medication or surgery. Among these modalities, Interferential Current Therapy (IFC) has demonstrated notable effectiveness. Research indicates that IFC provides superior pain relief for knee osteoarthritis (OA) compared to placebo treatments, outperforming other electrical nerve stimulation techniques in a 2015 review published in *Osteoarthritis & Cartilage*.
Other forms of electrotherapy, such as pulsed shortwave therapy (PSWT) and transcutaneous electrical nerve stimulation (TENS), have been investigated, although clinical evidence remains limited or inconclusive for specific knee complaints. The use of these therapies requires careful clinical reasoning, taking into account their thermal and non-thermal effects as well as appropriate contraindications and precautions before application.
Innovations in knee pain relief devices, such as those inspired by vibration therapy research, have historically been constrained by the need for large and costly equipment available only in hospital settings. Recent developments aim to make such treatments more accessible, leveraging advances in technology to offer effective pain relief at home.

Regulatory Approvals and Classification

The implantable post-surgical kinematic measurement knee device has been classified by the U.S. Food and Drug Administration (FDA) as a Class II medical device subject to special controls. This classification provides reasonable assurance of the device’s safety and effectiveness and is codified under 21 CFR 888.3600. The device is recognized for its capability to provide objective kinematic data following total knee arthroplasty surgery.
Manufacturers typically follow the classification and regulatory pathways established by the relevant product regulations in their target markets. In cases of uncertainty or disagreement regarding classification, the FDA offers the 513(g) process, allowing manufacturers to request an official opinion on their device’s regulatory status. FDA authorization under a Premarket Approval (PMA) constitutes an “approval,” whereas clearance under the 510(k) pathway indicates substantial equivalence to an existing device.
CE-marking plays a critical role for regulatory approval in many regions, especially in most Middle Eastern and African countries, where it often serves as a prerequisite for market entry. Consequently, obtaining CE-marking is often a strategic initial step for manufacturers targeting these areas. There are also ongoing proposals to accept FDA approval or clearance alongside CE-marking in countries such as Switzerland and the United Kingdom, which may simplify regulatory processes across multiple markets.
When planning regulatory strategy, manufacturers must consider factors beyond device classification. These include distribution channels (such as restrictions on distance sales or private labeling), reimbursement policies, and the presence of similar devices in the market. The existence of comparable devices can reduce the novelty of a new device and potentially simplify the evidence required for regulatory approval. Additionally, regulatory authorization in one country or region can sometimes support authorization efforts in others, creating synergies that facilitate broader market access.

Comparison with Other Treatments

Knee pain management encompasses a variety of treatment modalities, ranging from pharmacological approaches to physical therapies and advanced technological interventions. Compared to traditional methods, electrical stimulation therapies, including devices like the one featured in this article, offer a distinct mechanism of action and practical advantages.
Transcutaneous electrical nerve stimulation (TENS) is one of the most widely used neuromodulation therapies for knee pain. It functions by delivering electrical pulses that interfere with pain signals transmitted from the knee joint to the brain, thereby providing symptomatic relief. TENS units are available over-the-counter and allow patients to self-administer treatment conveniently at home. However, research specifically targeting TENS for knee conditions remains limited, and its effectiveness may vary depending on the clinical context.
Interferential current (IFC) therapy is another electrical stimulation modality shown to be more effective than placebo in reducing knee osteoarthritis pain, suggesting potential benefits over standard treatments. Nonetheless, such therapies are often employed as components of a broader physical therapy program rather than standalone interventions.
Multimodal physiotherapy, which combines various therapeutic approaches, has demonstrated effectiveness particularly for anterior knee pain relief. Unlike single-mode electrical stimulation devices, this strategy addresses multiple aspects of knee dysfunction but may require more extensive clinical oversight.
Traditional treatments for knee osteoarthritis primarily focus on symptom management through pain medications, joint injections, and ultimately, total joint replacement surgery. Since there is currently no cure for osteoarthritis, interventions that not only alleviate pain but also slow disease progression are highly desirable. Reducing mechanical loading on the knee joint remains a promising target within these therapeutic strategies.
Vibration therapy has also been explored as a treatment option for knee pain; however, it historically necessitated large and costly equipment, limiting accessibility to hospital settings. Modern devices that combine precise electrical stimulation with portability and ease of use, often including reusable therapy pads and knee wraps, represent a significant advancement by bringing effective treatment directly to patients outside clinical environments.

A significant point of contention lies in the limited scientific literature backing certain electrotherapy treatments, such as Pulsed Shortwave Therapy (PSWT) and Transcutaneous Electrical Nerve Stimulation (TENS), which are sometimes incorporated in knee pain relief devices. Current research highlights a lack of conclusive evidence and formal guidance—such as from NICE—on the use of PSWT for knee osteoarthritis, leading to cautious or non-recommendation by clinicians. Similarly, the therapeutic effects of TENS remain under-researched for specific knee complaints, and its use relies heavily on clinical judgment and individual patient considerations.
In addition to scientific scrutiny, regulatory hurdles have also been a source of criticism. The process for market authorization, particularly in regions requiring CE marking or US FDA approval, can be complex and lengthy. The influx of numerous guidance documents from authorities like the Medical Device Coordination Group (MDCG) has created challenges in maintaining compliance due to scattered and sometimes incomplete information. This situation complicates timely device approval and distribution, potentially delaying consumer access. Moreover, differences in regulatory requirements across regions can result in prolonged timelines, with CE marking often serving as a preliminary but not definitive step toward wider market entry.
These concerns underscore the need for rigorous clinical trials and clear regulatory pathways to ensure that knee pain relief devices deliver reliable benefits to users while meeting all safety and efficacy standards. Despite these challenges, company leadership expresses optimism about the device’s potential impact, emphasizing consumer access to lasting knee pain relief from home.
