Evidence is presented, largely from clinical sources, that a large collar is not necessary for the transfer of load to the proximal femur in cemented total hip arthroplasty. In fact, the use of a collar may have a number of deleterious side effects that cannot be predicted from theoretical analyses. Concern is also raised over the use of precoated femoral stems.
