Hypothesis
Knee pain correlates with tibial radiolucent lines and these lines appear most frequently in the most lateral and most medial zones of the tibial plateau.
Conclusion
Radiolucent lines around the tibial plateau are associated with knee pain in patients who underwent low-contact-stress total knee arthroplasty.
Supporting Evidence
- Radiolucencies were detected in 27 out of 28 patients with knee pain.
- Only 6 out of 28 matched controls without knee pain showed radiolucent lines.
- The study found a significant correlation between knee pain and the presence of radiolucent lines.
Takeaway
If you have knee pain after surgery, it might be because of gaps around the knee implant. Making sure the implant is set correctly can help reduce this pain.
Methodology
The study compared patients with knee pain to matched controls using X-ray analysis to assess tibial stress shielding.
Potential Biases
Potential bias due to multiple surgeons performing the procedures and the retrospective nature of the study.
Limitations
The study did not evaluate radiological data of the remaining pain-free patients and was conducted by multiple surgeons, which could introduce bias.
Participant Demographics
The mean age of participants was 68.3 years, with 72.8% female and 23.2% male.
