[Problems of alloplastic joint replacement (author's transl)].

Area of Science:

• Orthopedic Surgery
• Biomaterials Science
• Medical Engineering

Background:

• Artificial joint substitution is a key orthopedic procedure with good initial outcomes.
• Significant challenges persist, particularly concerning the long-term fixation of endoprostheses within living bone tissue.
• Current methods necessitate ongoing research into novel anchorage solutions.

Purpose of the Study:

• To explore and present alternatives to traditional implant anchorage methods in joint replacement.
• To evaluate the limitations and potential applications of cement-free anchorage techniques.
• To identify possibilities for joint substitution procedures that precede or replace current alloplastic interventions.

Main Methods:

• Review and presentation of existing and emerging cement-free anchorage strategies.
• Analysis of the limitations associated with various alloplastic joint substitution techniques.
• Indicative assessment of alternative treatment possibilities.

Main Results:

• While primary results of artificial joint substitution are positive, unsolved problems, especially implant fixation, remain.
• Cement-free anchorage methods are being actively investigated as potential solutions.
• Alternative approaches to alloplastic joint substitution exist and are being explored.

Conclusions:

• The field of artificial joint substitution is still evolving, with significant room for future advancements.
• Addressing implant-to-bone anchorage is crucial for improving long-term outcomes in joint replacement surgery.
• Exploring cement-free alternatives and other innovative techniques is essential for the progression of orthopedic surgery.
