Journal ArticleDOI
Normal and pathological adaptations of articular cartilage to joint loading.
TL;DR: The prevailing view is that osteoarthrosis starts from the cartilage surface through PG depletion and fibrillation of the superficial collagen network, and it has been suggested that the initial structural changes take place in the subchondral bone, especially when the joint is exposed to an impact type of loading.
Journal ArticleDOI
Osteoarthritis in the carpometacarpal joint of the thumb. Prevalence and associations with disability and mortality.
Mikko Haara,Markku Heliövaara,Heikki Kröger,Jari Arokoski,Pirjo Manninen,A Kärkkäinen,Paul Knekt,Olli Impivaara,Arpo Aromaa +8 more
TL;DR: The effect of thumb carpometacarpal osteoarthritis on disability and mortality in the general population is modest and is likely to be underdiagnosed in clinical practice.
Journal Article
Hip muscle strength and muscle cross sectional area in men with and without hip osteoarthritis.
Merja H. Arokoski,Jari Arokoski,Mikko Haara,Markku Kankaanpää,Minna Vesterinen,Lea Niemitukia,Heikki J. Helminen +6 more
TL;DR: Men with hip OA have significantly lower abduction, adduction, and flexion muscle strength than controls, and the decrease of muscle size and hip pain may contribute to the decreases of muscle strength in Hip OA.
Journal ArticleDOI
Back and abdominal muscle function during stabilization exercises
TL;DR: Women were better able to activate their stabilizing trunk muscles than men; but it is also possible that men, having a much higher degree of strength on maximal contraction, only need to activate a smaller amount of that maximum to perform a similar activity.
Journal ArticleDOI
Transgenic mice with targeted inactivation of the Col2 alpha 1 gene for collagen II develop a skeleton with membranous and periosteal bone but no endochondral bone.
Shi-Wu Li,Darwin J. Prockop,H.J. Helminen,R Fässler,T. Lapveteläinen,K. Kiraly,A Peltarri,Jari Arokoski,H Lui,Machiko Arita +9 more
TL;DR: The results demonstrate that a well-organized cartilage matrix is required as a primary tissue for development of some components of the vertebrate skeleton, but it is not essential for others.
