Area of Science:

Biomaterials science and engineering
Foot surgery innovations
Tissue engineering

Background:

Advances in biomaterials for foot surgery over four decades.
Current implants categorized as temporary (bone fixation) or permanent (joint replacement).
Limitations of current implants: temporary often left permanently, permanent implants degrade over time.

Purpose of the Study:

Discuss future directions in biomaterials for improved patient care in foot surgery.
Explore novel materials for bone fixation and joint replacement.
Address challenges and opportunities in biomaterial development.

Main Methods:

Review and categorization of existing implant materials.
Analysis of benefits and drawbacks of current temporary and permanent implants.
Projection of future biomaterial development based on current research.

Main Results:

Fully bioabsorbable polymer matrix composites are promising for bone fixation, offering initial strength without removal issues.
Tissue-engineered viable biomaterials are key for permanent articular cartilage replacement.
Current challenges include mechanical durability, degradation biocompatibility, and material self-sustainability.

Conclusions:

Bioabsorbable composites offer a solution for bone fixation, mitigating risks of implant retrieval or retention.
Truly permanent joint replacements necessitate self-regenerating, living tissues.
Interdisciplinary collaboration is crucial for advancing biomaterials science and tissue engineering.
