An optical fiber includes a core and a cladding, said cladding having a refractive index nc a first coating directly contacting the cladding of said fiber, said coating having a thickness of less than 10 microns, said coating having a refractive index delta %=100\xd72ni2 less than \u22121 percent. In particular, it is intended for the manufacture of transparent dressings. The platform is formed to define a platform circuit, and a substantially radially extendible pathway configured to be coupled to the appendage and to the platform circuit. The moldable inner support is only affixed to the band at its ends so that it may move freely with respect to the band and also provides focused pressure to reduce knee pain and helps stabilize the patella to improve alignment and tracking.
