Patterns of patellofemoral articular cartilage wear in Japanese cadavers

摘要: Abstract Introduction Although we recently reported a detailed description of wear pattern in Caucasians, few studies have investigated severity wear, and on the patella femur Japanese. The purpose this study was to determine if there is common joint specific patellofemoral Japanese cadavers. We further compared between US Methods examined 46 patellae matching femurs from 23 location transcribed gridded templates, that were for frequency, gender, sidedness wear. Results Over 60% showed odd facet, middle part medial aspect lateral facet. distal areas posterior femoral condyle anterior condyle. Patella may differ with gender as male’s more compact. area similar cadavers, be severe Discussion distinct regions articular cartilage patterns locations suggest occurs mainly when knees are moderately deeply flexed these result traditional style knee positions or activities.
