Water based exercise should be helpful, as it will decrease load on the joint but encourage range of motion and blood flow...
I can't get into the pool for probably another 1.5 weeks. I think that's going to be my saving grace, that and biking...
broke my ankle couple years ago, getting into the pool was definitely helpful and kept my recovery on track. good info in other posts, just wanted to add my two cents for when you're cleared to get in the water:
- i did all these exercises in water no deeper than my chest/stomach, mostly only up to my waist/crotch (3-4' maybe 5' part of the pool)
- started off with just walking up and down stairs (maybe you can put a workout box/step in the pool and do some high knee step-ups-step-downs)
- "running" across the pool, really just walking at first but this definitely helped because eventually i was running through the shallow end pumping my knees up out of the water. i started off doing really silly, exaggerated walking where i'd pick up my knees really high, extend my feet/calves, and take these biiiiiiig steps just to work range of motion and muscle memory
- side-steps with squats and then squat jumps eventually
- walking backwards
- balance exercises like standing on one foot and rotating my opposite leg at the hip
the way my PT described it to me, an important and overlooked part of rehab is regaining muscle memory, water therapy like this helps get your muscle memory and strength back in a very forgiving environment (less weight/gravity, soothing temps and light pressure to reduce swelling)
you could basically take whatever rehab exercises your PT has you do on dry land and do them underwater.
psychologically, it FEELS like you're getting ahead of schedule because you're thinking "wow i can walk up steps/run/jump/etc already" but really, since you're doing it underwater, you're just taking baby steps so it's less likely for you to over-do it and set your recovery back (just remember this when you're back on dry land! haha)
GL with your rehab and congrats on the upcoming wedding
ps, just remembered, if you like swimming then definitely do that too! (and if you don't, start doing it anyway) it's a full body work out and that increases natural testosterone production which aids your body's natural healing ability.
