Abstract:
A knee brace comprising:a femoral component including a femoral joint member having a first mating surface and a second mating surface arranged at a first obtuse angle to said first mating surface, said femoral component further including a stem projecting from said femoral joint member for attachment to the upper leg of a patient so as to fix said femoral component relative to said upper leg; a tibial component including a tibial joint member having a first bearing surface and a second bearing surface arranged at a second obtuse angle to said first bearing surface; said first and second bearing surfaces being in contact respectively with said first and second mating surfaces of said femoral joint member, said first bearing surface of said tibial joint member being complementary to said first mating surface of said femoral joint member and said second bearing surface of said tibial joint member being complementary to said second mating surface of said femoral joint member; and wherein said tibial component further includes a stem projecting from said tibial joint member for attachment to the lower leg of the patient so as to fix said tibial component relative to said lower leg; a mounting member, said femoral joint member and said tibial joint member being arranged in juxtaposition in said mounting member, wherein said first and second bearing surfaces of said tibial joint member are in contact with said first and second mating surfaces of said femoral joint member, wherein at least a portion of said femoral joint member is fixed to said mounting member, and wherein said tibial component is rotatable relative to said femoral joint member; and a resilient member, said resilient member being arranged between an inner surface of said mounting member and said opposite surface of said tibial joint member to bias said tibial joint member toward said femoral joint member.
