3 acl repairs + hto 15 yrs ago--left with ++ instability in knees. instability seems much worse since pregnancy. will worsen with futur pregnancy?

Bad problem: To have as much work done on your knee at your age you have beat up your knee and are unfortunately going to have (if not already) progressive arthritis. The fact that you already had an hto would indicate they were trying to offload a part of your knee. Preganancy going to probably add to the pain due to the added weight so try to maintain a normal weight gain w pregnancy. Good luck.
