Brief Summary

Nearly one out of every two Americans will develop knee osteoarthritis by age 85. Over 20 million Americans, including nearly three million Veterans, currently have painful knee arthritis that limits their daily activity or recreation. The vast majority of those individuals will be prescribed anti-inflammatory drugs that provide some pain relief but do not slow the progression of the disease. Often people with knee arthritis are told they must live with the pain until they become appropriate candidates for knee replacement surgery, but that can require tolerating the pain and limiting function for many years. Because of other health issues, some individuals are never acceptable surgery candidates. What is desperately needed are better conservative approaches for treating these patients. Two such approaches will be tested and compared in this study.

Outcome Measures

Primary Outcomes (2)

  • Change in Medial Knee Pain

    Change in medial knee pain between baseline and week 52 using an 11-point Numeric Rating Scale (NRS) to assess average medial knee pain over the past 7 day period. Possible scores range from 0 (no pain) to 10 (worst pain imaginable). Change = (Week 52 score - Baseline score).

    Baseline and Week 52

  • Change in Knee Adduction Moment

    Change in magnitude of the more prominent peak in the knee adduction moment (KAM), a surrogate measure for medio-lateral load distribution in the knee, between baseline and week 52. A reduction in KAM indicates a shift in loading from the medial to the lateral compartment of the knee. Change = (Week 52 - Baseline).

    Baseline and Week 52

Secondary Outcomes (4)

  • Change in Medial T1rho Relaxation Time

    Baseline and Week 52

  • Change in Medial T2 Relaxation Time

    Baseline and Week 52

  • Change in Lateral T1rho Relaxation Time

    Baseline and Week 52

  • Change in Lateral T2 Relaxation Time

    Baseline and Week 52

Study Arms (2)

Gait Training; Altered Foot Progression Angle

EXPERIMENTAL

Participants will receive personalized gait training while walking on a treadmill with real-time, haptic feedback. The goal of the training is to encourage participants to adopt an altered foot progression angle in an attempt to alter the distribution of forces crossing the knee joint. Training will occur once a week for six weeks. This will be followed by a 46-week home and community-based walking program to practice and internalize the new personalized, gait pattern and to encourage daily walking. Refresher training with haptic feedback will be offered at weeks 11, 25 and 39 to enhance internalization of the new foot progression angle.

Other: Gait Training; Altered Foot Progression Angle

Gait Training; Consistent Foot Progression Angle

EXPERIMENTAL

Participants will receive personalized gait training while walking on a treadmill with haptic feedback. The goal of the training is to encourage participants to maintain a consistent foot progression angle in an attempt to minimize the variability in the forces crossing the knee joint. Training will occur once a week, for 6 weeks. This will be followed by a 46-week home and community-based walking program to encourage daily walking. Refresher training with haptic feedback will be offered at weeks 11, 25 and 39 to maintain foot progression angle consistency.

Other: Gait Training; Consistent Foot Progression Angle

Interventions

Participants will receive personalized gait training while walking on a treadmill with real-time, haptic feedback to encourage them to adopt a new foot progression angle. Participants will walk for an additional ten minutes per day to internalize their new foot progression angle over 52 weeks.

Gait Training; Altered Foot Progression Angle

Participants will receive personalized gait training while walking on a treadmill with haptic feedback to encourage them to maintain a consistent foot progression angle. Participants will walk an additional ten minutes per day to internalize the consistency of their foot progression angle over 52 weeks.

Limitations and Caveats

Enrollment was lower than expected due to the fact that most interested participants did not meet study inclusion criteria. As a result, we did not reach our pre-specified sample size of 80 participants. In addition, the institutional shutdown due to the COVID-19 pandemic resulted in 7 participants not completing the full 1-year intervention.
