The various implants used in total hip arthroplasty can be classified according to the design and the fixation type. In general, they can be divided into two groups; cemented and cementless types. The surgeon's decision regarding which type of implant to use should be based on the goal of the arthroplasty operation, the bony deformity of the patient, the function of the involved hip joint, and the experience of the operator. When using cementless implants, primary fixation, survival rate, and successful fixation on long-term follow-up depend on the material of the implant, the bone quality, and, ultimately, the interaction between the implant and the bone. Cementless implants have shown a high success rate in primary total hip arthroplasty and relatively fine outcomes on long-term follow-up. In comparison of the two implant types, superiority has yet to be determined, however, a choice made based on the objective of the surgery, the function of the joint, the quality of the bone, and the surgeon's experience will result in a good outcome. Therefore, we reviewed the qualities of cementless implants, the application, and the various procedures involving the implant.
