Significant fibrosis ATFL and CFL. No significant fibrotic change at the PTFL which also had undergone strain at the time of the original injury. Significant ongoing swelling at the MCL - deltoid ligament complex. Evidence of early degenerative change tibial plafond laterally and bony reactive oedema medial malleolus.


Case summary:

44 years old with medial and lateral pain 8 months post supination injury. complains of instability.

Question(s) to this case:

I am considering arthroscopy and lateral ligament reconstruction (open). I am concerned about the medial sided changes and whether they can be addressed arthroscopically. I am also concerned that her laxity does not reproduce her symptoms. should the medial sided lesions be addressed arthroscopically?


Looks like cystic lesions in the PTT sliding channel. It is best to open the PTT grove and create a smooth groove after debridement.
