Arthroscopy has a higher discriminative capacity than MRI in detecting mild cartilage lesions
Authors' conclusion
Despite significant technological advancements in MRI, arthroscopy still proves superior in identifying mild structural cartilage lesions that are not identifiable by this technique.
Study context
- Population
- Adults with knee pain >3 months scheduled for therapeutic/diagnostic arthroscopy
- Participants
- 95 adults
- Comparison
- MRI vs arthroscopy in detecting cartilage lesions in the medial femoral condyle
- Outcome
- Detection of cartilage lesions in the medial femoral condyle (MFC) by MRI vs arthroscopy
Performance
As reported in the abstract
Patients with MFC lesions detected
Arthroscopy
48
events
MRI
24
events
Further findings
Medial femoral condyle (MFC) cartilage thickness
- Significantly lower in patients with cartilage damage detected by MRI vs those without
Arthroscopic lesions with vs without MRI lesions
- Those also showing lesions on MRI had lower cartilage thickness and higher Outerbridge score
Age and pain, MRI-detectable damage vs damage detected only by arthroscopy
- Patients with MRI-detectable damage were significantly older and reported higher pain
