“…Bone tissue integration to implants requires a perfect initial and ultimate stability of their junction. This stability depends, to a great extent, on the shape and geometry of the implant, as well as on its surface coating, the preliminary fitting of the implant in the patient’s osseous bed, and on load distribution in the implant-bone junction [4,5]. Numerous reports have recently been published in the relevant literature, broadly covering the issues of understanding biofunctionality of different types of endoprostheses in the patient’s body, assessing, among other things, the long-term outcomes of alloplastics, bone tissue remodeling around the proximal and distal parts of prosthesis stem, comparing different types of endoprostheses (e.g., cemented or cementless ones, and short or long stems), assessing the causes of prosthesis loosening after implantation, and even evaluating the quality of life in patients who underwent alloplastic [6–9].…”
