Foot Orthotics and Patellofemoral Pain

The focus in recent times on patellofemoral pain or anterior knee pain in runners has all been on the proximal issues despite two randomized controlled trials showing that distal issues (ie foot orthotics) work (see Collins et al Continue reading

Increasing cadence and patellofemoral forces

Hot on the heels of the study from last week on Barefoot vs Shod and patellofemoral joint stresses which showed that running barefoot reduced patellofemoral stress by 12%, we now have another new study that looked at patellofemoral loads and cadence: Increasing Running Step Rate Reduces Patellofemoral Joint Forces Lenhart, Rachel L.; Thelen, Darryl G.; Wille, Christa M.; Chumanov, Elizabeth S.; Heiderscheit, Bryan C.

Barefoot vs Shod and patellofemoral joint stresses

There is an increasing number of studies on patellofemoral pain syndrome or anterior knee pain in runners and the affects of gait changes in the biomechanics of it. The British Journal of Sports Medicine just published this: Take your shoes off to reduce patellofemoral joint stress during running Jason Bonacci, Bill Vicenzino, Wayne Spratford, Paul Collins Br J Sports Med doi:10.1136/bjsports-2013-092160 Aim: Elevated patellofemoral joint stress is thought to contribute to the development and progression of patellofemoral pain syndrome. The purpose of this study was to determine if running barefoot decreases patellofemoral joint stress in comparison to shod running Continue reading

Forefoot strikers exhibit lower running-induced knee loading than rearfoot strikers

One thing that I have been consistent in saying is that different running forms load different tissues differently. From a clinical perspective, this is not a matter of one ‘form’ being better than another, its about what gait changes can be made to reduce the load on any tissues that there are problematic issues with Continue reading

The Paradox of Patellofemoral Pain Syndrome and Foot Biomechanics

Probably the most common injury seen in runners is “runners knee” – or patellofemoral pain syndrome (PFPS) or anterior knee pain or what it used to be called a long time ago, chondromalacia patallae. Typically the pain is around the patella and is aggravated by activity. Continue reading

Lateral Wedging for Medial Knee Osteoarthritis

The two main risk factors for medial knee osteoarthritis is obesity and a higher external knee adduction moment. Laterally wedging the foot or shoe has been shown to reduce this adduction moment in many people (but not all) and clinical trials appear to show that it is helpful in many people (but not all). Continue reading
