Bone defect at lateral aspect of medial femoral condyle.
A bone fragment anterior to the ACL.
Case Discussion
The lesion is stable when the bony fragment is still in place but when the fragment is detached and displaced from the mother bone secondary osteoarthritis may develop and hence unstable lesion requires surgical intervention.
