Introduction

Orthopaedic biomaterials have evolved significantly over the past decades. This narrative review examines key developments and future directions.

Biodegradable Implants

Magnesium-based and polymer implants offer the advantage of gradual load transfer to healing bone, reducing stress shielding.

Bioactive Coatings

Hydroxyapatite and growth factor coatings enhance osseointegration and may reduce revision rates in joint arthroplasty.

Additive Manufacturing

3D printing enables patient-specific implants and porous structures that promote bone ingrowth.

Conclusion

The future of orthopaedic biomaterials lies in smart, bioactive, and personalised solutions.
