HPI - 17 year old obese female. BMI 37.2
Playing football with friends. Twisted knee and heard a pop and swelling.
MRI shows acl tear and medial meniscus tear, but standing xrays show significant lateral joint widening.
Full length scanogram shows significant varus alignment.
Difficult to really evaluate posterior lateral corner structures due to obese knee. I did not appreciate any increased external rotation.
What to do for this young pt?
ACL reconstruction alone?
ACL and HTO?
What surgery would you perform?
