Amyloid in Osteoarthritic Hip Joints:Depositions In Cartilage And Capsule. Semiquantitative Aspects

Amyloid depositions in tissue from 116 osteoarthritic hip joints were examined. There was no significant correlation between amyloid and age although there was a tendency for joints from older patients to have more marked amyloid degeneration. We found significantly more amyloid in the joint capsules from male patients than from females. No difference in amyloid deposition was found between the right and left side, and pressure-loaded/less pressure-loaded parts of the femoral head contained equal amounts of amyloid. With the exception of two cases amyloid depositions in the joint capsule were always accompanied by amyloid in the joint cartilage (P < 0.001). Conversely the cartilage was often positive when the capsule was negative for amyloid.
