Study Explores The Link Between Knee Osteoarthritis & Foot Pain

A new study published in the journal of Arthritis Care and Research found that about 25% of patients with knee osteoarthritis also have foot and ankle pain.1http://www.medpagetoday.com/Rheumatology/Arthritis/52399 The investigation of 1,255 patients found that people with foot pain and knee osteoarthritis were more likely to be young and female with a higher BMI. More than half the patients (54.9%) suffered from bilateral foot pain. Researchers could not determine whether the foot pain caused the knee problems, the knee problems caused the foot pain, or if both issues arose simultaneously, but they surmised that pronation and other biomechanical conditions resulted as patients overcompensated for the knee arthritis, and that overcompensation worsened the pain.

Foot Pain Worsens Outcome For Osteoarthritis Patients

Arthritis patients with concurrent foot pain performed significantly worse in terms of:

– Pain (7 vs. 5 on the WOMAC scale)

– Stiffness (4 vs. 3 on the WOMAC scale)

– Function (21 vs. 14.9 on the WOMAC scale)

– Mental (54.4 vs. 56.3 on the SF-12 scale)

On these scales, a two point difference is considered “clinically significant.” Patients with both types of pain walked slower and performed significantly slower on the repeated chair stand test, researchers noted. “Future research, they said, should investigate the effects of interventions targeted toward the treatment of aberrant foot posture and/or pain in knee OA patients,” the authors noted. It may sound like these conclusions are fairly obvious, but the study illuminates the importance of podiatric care in the overall treatment of arthritis patients.2http://www.scpod.org/foot-health/common-foot-problems/osteoarthritis/

What Can Podiatrists Do For Osteoarthritis of the Knee?

Research indicates that wedge orthotics are not necessarily beneficial for all patients, but may help some on a case-by-case basis. More importantly is an arthritis patient’s choice of footwear. “Wearing flat-heeled, flexible shoes—especially ones that mimic the natural movement of walking barefoot” has been proven to slow the progression of osteoarthritis in the knee, reports Harvard Health.3http://www.health.harvard.edu/blog/insoles-no-help-for-knee-osteoarthritis-201308216629 One study cited by Podiatry found that switching to minimalist shoes led to an 18% reduction of force to the medial knee, as well as a reduction in pain of 36%.4http://www.podiatrytoday.com/blogged/can-minimalist-shoes-be-beneficial-osteoarthritis-related-knee-pain

A few brands of flexible, minimalist shoes recommended for osteoarthritis patients include:

– Dr. Comfort Flex-OA

– Moleca®

– Merrell Vapor Glove 2

After an examination, we can offer more tailored suggestions to benefit your particular anatomy.
