NCT02254473

Brief Summary

This study is looking at the efficacy of a sloped insole in patients with knee osteoarthritis. Regularly wearing a sloped insole over the course of one year will result in a wider joint space by x-ray in 60% of the subjects, a significant decrease in knee pain, decreased use of over the counter analgesics, and a clinically important improvement in the Womac pain and stiffness scale.

Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adult patients 30 years or older with medial compartment knee Osteoarthritis (unilateral) and Grade 4 Kellgren-Lawrence39 radiographic changes presenting for treatment of knee pain.
  • Range of motion knee-flexion beyond 100 degrees and not lacking more than 15 degrees of extension.
  • Subtalar and forefoot motion permitting foot/ankle eversion with weight bearing.
  • Sufficient shoe toe box height to allow space for the insole and therefore comfort and compliance.
  • Passive laxity of medial capsule and collateral ligament by knee extension test.

You may not qualify if:

  • All other forms of knee arthritis other than OA.
  • Knee Instability- medial pseudo-opening of greater than grade 1 or detectable Anterior-posterior instability.
  • Less than Grade 4 Kellgren-Lawrence radiographic changes in the medial compartment of the knee39.
  • Grade 2 or greater Kellgren-Lawrence radiographic39 involvement of the patellofemoral or lateral compartment.
  • Inadequate knee range of motion
  • Balance problems requiring the use of a walker or wheel chair - ambulation with aid
  • Diabetics with peripheral neuropathy
  • Knee surgery within the past year
  • Intraarticular steroid injection or visco supplementation within 6 months
  • Stiff subtalar or forefoot joints - clinical test
  • Inadequate shoe toe box depth to accommodate the test or control inserts
  • Charcot joint
  • Fixed contracture of the medial capsule and/or collateral ligament- clinical test
