Hi, I broke tibia fibula and malleus 15 mtgs ago and got a plate and six screws into tibia. 6 weeks ago I had the plate and screws removed and ankle feels great. I m walking really well and have been doing low impact exercise, weights, leg lifts, yoga etc, since 2 days post op. I would love to start doing aerobics again and was wondering when it would be safe to do so? I realise there are six holes there and am not sure how long they take on average to fill in. Hopefully you can help. :) Thanks in advance! :)
