Cementless Knee Arthroplasty in Rheumatoid Arthritis

Abstract

Considering the often young age and weak bones of rheumatoid arthritis patients, the long-term fixation of a prosthesis to the bone is still the central problem. The durability of the fixation depends on the interface stresses, which are related to the constraint of the prosthesis. To minimise these stresses the least constrained prosthesis providing sufficient stability is favoured. Even in newer cementing techniques the ageing of the acrylic cement cannot be avoided. These techniques also have the disadvantage of sacrificing more bone stock in cases of revision because of the greater depth of cement penetration.
