Related...yes: Ligaments connect bone to bone. Ligament instability means that the supporting structures are not holding the joint in alignment for efficient motion. The knee, leg (tibia) and ankle are all connected and if one component is weak, the others will compensate. Osteoarthritis is basically a wear and tear of the joint. If the joint is not stable, the bones rub and become irritated and inflamed.

Instability: Usually relates to ligaments which attach to bone. Medial os tibia laxity is unusual more often seen on lateral side or fibula side unless the deltoid ligament is the issue. Mri would be helpful.
