Presentation
Had chronic knee pain with intermittent locking. OCD repaired, now for check of fragment union
Patient Data
Osteochondral fragment has been retrieved and reattached arthroscopically using 2 dissolvable pins (arrow). The bone has almost united with a reasonable cover of overlying articular cartilage
Large well-established OCD (arrow) on lateral aspect of the medial femoral condyle with a large cavity and separated osteochondral fragment sitting in the supra-patellar recess laterally (arrow)
Case Discussion
Once the OCD fragment has separated it is still worthwhile attempting to reattach in order to establish a smooth articular surface. When reporting MRI it is important to localize the fragment for the surgeon.
