The main questions it aims to answer are:Is there any relationship between knee pain and disability in knee osteoarthritis and MLA height?Is there any relationship between the radiologic severity of knee osteoarthritis and MLA height?Is there any relationship between knee joint alignment in knee osteoarthritis and MLA height?
