Tibial component fixation in knee arthroplasty.

L Ryd, A Lindstrand, R Rosenquist

Clinical Orthopaedics and Related Research

|December 1, 1986

Summary

Tibial component migration and displacement are common after total knee arthroplasty (TKA). These findings suggest that absolute rigid fixation may not be essential for successful TKA function.

Background:

Total knee arthroplasty (TKA) aims to restore function in patients with gonarthrosis.
Assessing the stability of prosthetic components is crucial for long-term TKA success.
Roentgen stereophotogrammetric analysis (RSA) is a precise method for measuring micromotion.

Purpose of the Study:

To evaluate the migration and displacement of cemented tibial components in Kinematic total knee prostheses.
To determine the incidence and magnitude of tibial component micromotion post-surgery.

Main Methods:

Utilized roentgen stereophotogrammetric analysis (RSA) to track tibial component movement.
Studied seven patients with cemented Kinematic total knee prostheses implanted for gonarthrosis.
Monitored migration over a two-year period and assessed displacement under external forces.

Main Results:

All seven patients exhibited tibial component migration, ranging from 0.3 to 1.9 mm over two years.
Five patients showed inducible displacement (0.2 to 1.0 mm) when subjected to external forces.
Measurable migration and displacement appear to be common occurrences in TKA.

Conclusions:

Micromotion of the tibial component is a frequent finding in cemented Kinematic total knee arthroplasty.
Absolute rigid fixation of the tibial component may not be a prerequisite for successful TKA outcomes.
These findings have implications for the design and fixation strategies in total knee arthroplasty.
