Modular porous tantalum tibia baseplates in total knee arthroplasty (TKA) can fracture due to fatigue. Metal debris and poor bone ingrowth may contribute to this failure, necessitating further investigation into implant longevity.

Area of Science:

Orthopaedic Surgery
Biomaterials Science
Materials Engineering

Background:

Porous tantalum is widely used in uncemented total knee arthroplasty (TKA) with earlier designs showing favorable outcomes.
Evolution to modular implants aimed to improve TKA performance.
This study investigates causes of medial tibia bone loss and subsequent modular porous tantalum tibia baseplate fracture after primary TKA.

Purpose of the Study:

To analyze the causes of extensive medial tibia bone loss and modular porous tantalum tibia baseplate fracture.
To investigate the role of metal debris and bone ingrowth in implant failure.

Main Methods:

Proton-Induced X-ray Emission (micro-PIXE) elemental analysis of retrieved tissue samples.
Stereomicroscopy for fractographic and microstructural analysis.

Keywords:

3D finite-element modeling for stress-strain analysis of the tibial baseplate.

Main Results:

Histological examination revealed tantalum and titanium metal debris under the fractured baseplate.
Fractographic analysis indicated the tibial baseplate failure met criteria for fatigue fracture.
Bone ingrowth was observed on only 22.5% of the contact surface, particularly limited on the medial side.

Conclusions:

Modular porous tantalum tibia baseplate fracture in TKA is likely due to fatigue.
The presence of metal debris and limited bone ingrowth, especially medially, may contribute to bone resorption and catastrophic failure.
Further research is required to confirm the link between metal debris, bone absorption, and tibial tray failure.
