Hypothesis
The study aims to evaluate the endurance of an alloplastic cord and its fixation device during normal daily life activities after tibial replacement.
Conclusion
The Trevira cord can provide temporary stability and extensor function until scar tissue can take over this function.
Supporting Evidence
- The Trevira cord ruptured at a mean tensile load of 2558 N.
- Conditioning in saline for 25 days reduced the load to failure by approximately 12%.
- Dynamic loading tests showed that the cord scrubbed at the proximal edge of the metal block until it ripped.
Takeaway
Doctors are testing a special cord to help people move their knees better after surgery for bone cancer. This cord can hold things together until the body heals itself.
Methodology
Biomechanical tests were conducted on a Trevira cord under various loading conditions to evaluate its performance before and after physiological conditioning.
Limitations
The study was limited to a specific type of cord and fixation device, and results may not be generalizable to other methods.
