Trial Summary

Do I need to stop taking my current medications for this trial?

The trial protocol does not specify whether you need to stop taking your current medications. However, if you have had corticosteroid injections in the knees in the previous 6 weeks, you are not eligible to participate.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. However, if you have had corticosteroid injections in the knees in the past 6 weeks, you would not be eligible to participate.

What data supports the idea that Biomechanical Footwear for Knee Osteoarthritis is an effective treatment?

The available research shows mixed results about the effectiveness of Biomechanical Footwear for Knee Osteoarthritis. Some studies report that it can help reduce knee pain, but they also emphasize the need for more research to confirm these findings. One study found that using specialized footwear for six months could improve knee function by reducing stress on the knee. However, the benefits of this therapy are still unclear, and the high cost of around $5,000 makes it a less attractive option without stronger evidence. Compared to other treatments, the evidence for Biomechanical Footwear is not strong enough to recommend it as a routine option for knee osteoarthritis.12345

What data supports the effectiveness of the treatment AposHealth Biomechanical Footwear for knee osteoarthritis?

Some studies suggest that biomechanical footwear may help reduce knee pain and improve physical function in people with knee osteoarthritis, but the evidence is not strong enough to confirm its long-term effectiveness and safety. Further research is needed to determine its true clinical value.12345

What safety data exists for biomechanical footwear in treating knee osteoarthritis?

The available research on biomechanical footwear for knee osteoarthritis suggests potential benefits in pain alleviation, but the evidence is weak and further investigation is needed to confirm its long-term effectiveness and safety. The BIOTOK Randomized Clinical Trial indicates possible improvements in pain and physical function, but the benefits remain unclear. Overall, there is a lack of conclusive safety data, and more studies are required to establish the treatment's safety profile.13467

Is biomechanical footwear safe for humans?

The safety of biomechanical footwear for knee osteoarthritis is not well-established, as studies suggest more research is needed to evaluate its long-term safety and effectiveness.13467

Is AposHealth a promising treatment for knee osteoarthritis?

AposHealth, a type of biomechanical footwear, shows potential in reducing knee pain and improving function for people with knee osteoarthritis. Some studies suggest it can help by decreasing the load on the knee, which might slow down the disease and reduce pain. However, more research is needed to confirm its long-term effectiveness and safety.13489

How is AposHealth Biomechanical Footwear different from other treatments for knee osteoarthritis?

AposHealth Biomechanical Footwear is unique because it aims to reduce knee pain and slow disease progression by decreasing knee loading through specialized footwear, rather than using medication or invasive procedures. However, its long-term effectiveness and safety are still uncertain, and it is relatively expensive.13489

What is the purpose of this trial?

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.

Eligibility Criteria

This trial is for men and women aged 45-80 with knee osteoarthritis, who've had symptoms for at least six months. They must have a certain level of pain and be able to understand and sign the consent form in English. It's not for those with severe balance issues, BMI over 40, recent steroid injections in the knees, major past knee surgeries (except arthroscopy), more severe non-knee pain, inflammatory diseases or recent mental health conditions.

Inclusion Criteria

Treatment Details

Interventions

  • AposHealth
  • Total Knee Replacement (TKR)
Trial Overview The study tests AposHealth as an alternative to Total Knee Replacement (TKR) surgery for knee osteoarthritis patients and as a post-operative tool after TKR. AposHealth is a home-based biomechanical treatment designed to improve joint function without surgery.
Participant Groups
3Treatment groups
Experimental Treatment
Active Control
Group I: Post TKR traditional physical therapy (PT) and AposHealthExperimental Treatment2 Interventions
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.
Group II: AposHealthExperimental Treatment1 Intervention
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.
Group III: Total Knee Replacement (TKR)Active Control1 Intervention
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.

Findings from Research

Current literature suggests that biomechanical footwear may help alleviate knee pain in individuals with osteoarthritis, but the evidence is not strong enough to confirm its long-term effectiveness and safety.
Due to the high cost of biomechanical footwear (around $5,000) and the lack of robust evidence supporting its efficacy, routine use of this treatment is not recommended until further research confirms its benefits.
The Effect of Biomechanical Footwear on Pain from Knee Osteoarthritis.Rodriguez-Merchan, EC., la Corte-Rodriguez, H., Roman-Belmonte, JM.[2022]
Lateral wedge orthotics effectively reduce the peak external knee adduction moment (EKAM) in both healthy individuals and those with medial knee osteoarthritis, while medial wedges may increase EKAM.
Modern footwear, including stability and mobility shoes, tends to increase EKAM compared to barefoot walking in individuals with medial knee OA, indicating a need for better footwear design to minimize knee stress.
Effect of footwear on the external knee adduction moment - A systematic review.Radzimski, AO., Mündermann, A., Sole, G.[2022]
After 6 months of wearing flat, flexible footwear (mobility shoes), participants with knee osteoarthritis experienced an 18% reduction in knee loading, indicating improved biomechanics and potential pain relief.
The study also found that even after removing the mobility shoes, participants maintained a significant reduction in knee loading, suggesting that these shoes can help retrain gait mechanics beneficially for knee OA.
