title: Middle-term results of a cementless threaded self-tapping acetabular cup.
abstract: Various designs of acetabular cup are available for cementless fixation in patients undergoing total hip arthroplasty. Conflicting results have been reported in the literature about the middle to long-term outcomes with the use of these cups. We present our experience of a design of self-tapping threaded acetabular cup with metal backing (the ACSYS acetabular cup). This is a study of 41 hips with average follow up of 6.43 years. Functional grading of the hips was very satisfactory and none of the patients needed revision for aseptic loosening. No case of significant cup migration or osteolysis was noted. The paper also reviews the literature.
