Biomechanical Footwear as a Non-invasive Alternative and Supplement to Total Knee Replacement

Study Purpose

Osteoarthritis (OA), the most common type of arthritis, affects more than 32.5 million adults in the United States. It is also among the most expensive condition to treat when joint replacement surgery is required. Although biomechanics plays an important role in OA disease, the non-surgical treatment options addressing biomechanics are scarce with limited effect. AposHealth is the fist biomechanical treatment that was shown to have a significant short-term effect on patients with knee OA. The main objectives of this study are: 1. To assess AposHealth, a non-invasive home-based biomechanical treatment, as an alternative treatment for patients who are eligible for Total Knee Replacement (TKR). 2. To assess AposHealth as a new post-operative rehabilitation tool for patients post TKR.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT04732962
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	N/A

Additional Details

Osteoarthritis (OA), the most common type of arthritis, affects more than 32.5 million adults in the United States. It is also among the most expensive condition to treat when joint replacement surgery is required. Future projections of the prevalence of OA predict an increase in prevalence, mainly due to the aging of the population and obesity. Total knee replacement (TKR) is the end-stage solution for patients with knee OA. The total annual cost of arthritis in the U.S. in 2013 reached over $300 billion. Expenditure is expected to grow significantly in response to the increase in prevalence and the projected number of TKRs. Successful and beneficial non-invasive treatment options for knee OA are limited. More specifically, although biomechanics plays an important role in OA disease, the non-surgical treatment options addressing biomechanics are scarce with limited effect. AposHealth is the fist biomechanical treatment that was shown to have a significant short-term effect on patients with knee OA. The main objectives of this study are: 1. To assess AposHealth, a non-invasive home-based biomechanical treatment, as an alternative treatment for patients who are eligible for TKR. 2. To assess AposHealth as a new post-operative rehabilitation tool for patients post TKR.

Arms & Interventions

Arms

Experimental: AposHealth

Following the initial consultation and calibration of the Apos device in the clinic, the patients will receive from his therapist a home-based treatment plan. This usually includes wearing the device for about 20 minutes with about 20% of weight-bearing (patient is instructed to wear the Apos and just be with the device and go about his/her daily routine). A gradual increase in usage time is prescribed reaching up to 60 min wear time with about 40% weight-bearing. Patients are requested to return to follow-up (FU) appointments after 1, 3, 6, 9 and 12 months. In addition, patients will have a remote FU after 1-week to confirm they use AposHealth as advised. During the follow-up appointment, re-assessment of clinical outcomes and gait patterns are performed and the calibration of the Apos device is adjusted as needed. The treatment plan is adjusted, and patients are encouraged to continue to wear the device regularly at home.

Active Comparator: Total Knee Replacement (TKR)

Patients will undergo TKR according to Geisinger's policy, guidelines and care protocol. The study baseline visit will occur 6 weeks postoperative for TKR groups.

Experimental: Post TKR traditional physical therapy (PT) and AposHealth

Patients who have had a knee replacement and were assigned to the traditional PT+ AposHealth group will follow Geisinger post-operative rehab protocol and will also receive AposHealth and follow the rehabilitation protocol. AposHealth will start six weeks post-op and will continue for 12 months. Patients will receive AposHealth similar to the non-invasive group, i.e., will have an initial evaluation (IE) and calibration of the Apos device, have a remote FU after one week from IE and in-clinic FUs at 1, 3 6, 9 and 12 months.

Interventions

Device: - AposHealth

AposHealth is comprised of a unique footwear (Apos device) and uses two convex pods called "Pertupods", which are screwed into the plantar surface of the sole so that a person walks on these pods. A trained Apos therapist calibrates the devices. The location of the pods is adjusted according to the treatment methodology, depending on the needed effect on unloading the knee and with the purpose of potentially alleviating pain immediately.

Procedure: - Total Knee Replacement (TKR)

A total knee replacement occurs when a diseased or damaged knee joint is totally replaced with an artificial joint called an implant. The implant consists of high-grade metal and plastic components that fuse to the resurfaced bone. It is designed to move like a healthy human joint.
