Hypothesis
Patients with worse preoperative knee cartilage or meniscus lesion on MRI will have worse postoperative outcome survey scores at a minimum 2-year follow-up after cartilage restoration.
Conclusion
Increasing preoperative degenerative change in the knee, as evidenced by a higher WORMS on preoperative MRI, was associated with inferior patient-reported outcomes at a minimum of 2 years after cartilage restoration surgery.
Supporting Evidence
- The maximum preoperative WORMS score was significantly correlated with the postoperative Lysholm score.
- The WORMS Meniscus and Cartilage subscales were significantly correlated with the Lysholm score.
- The maximum WORMS score was significantly correlated with the Knee injury and Osteoarthritis Outcome Score daily living and sports/recreation subscores.
- Semiquantitative synovial inflammation imaging biomarkers were not significantly correlated with PRO scores.
Takeaway
If your knee has more damage before surgery, you might not feel as good after the surgery. Doctors can use special scans to help predict how well you'll do after your knee surgery.
Methodology
Patients who underwent knee articular cartilage restoration were evaluated using preoperative MRI and patient-reported outcome measures at a minimum 2-year follow-up.
Potential Biases
Potential biases due to the retrospective nature of the study and the inclusion of multiple surgical methods.
Limitations
The study had a limited sample size and did not collect preoperative PRO scores, which could affect the analysis of treatment effectiveness.
Participant Demographics
Average age was 34.5 years, with 26 men and 14 women; average BMI was 28.2.
