fibula weakness/dislocation

Question
I'm no medical expert (obviously) but I don't know what muscles hold the top of the fibula in place.  I'm assuming the weight exercises you've suggested cover that muscle or group of muscles so I will start doing some weight stuff for my legs (again assuming it won't hurt to do these exercises for both legs instead of just the one).  Until that has built the muscles up enough to give me that added stability would I be okay to wear some sort of band/brace?  I'm determined to do this half marathon in January and don't want to side track my training while waiting for my knee to get stronger.  This muscle laxity issue affects a number of joints, not just the one knee so I've never been gung ho about any sport but have started running with my dad and am finding I'm enjoying it more than I ever dreamed and want to do all I can to keep doing it.

Question -
Hi, I've just started training for a half marathon and am having some issues with one of my knees.  My left knee has a funky fibula - since I was a kid I've been able to (what I think is) dislocate my fibula at will.  When relaxed I can push it and it'll "pop" out of place and sit about 15mm out from where it normally is.  No pain in doing this and it doesn't stay that way by itself, but definite weakness in the muscles that are supposed to hold it in.  In the way past I've had it pop out on me a few times while running, causing me to stumble, before it self-rights and I can continue, but since I haven't done any running in the past 15 years or so until now I haven't had that problem.  (years ago I had a Dr tell me it was a condition where my muscles didn't tighten back fully after I grew)  Now when I run it feels weak though and I'm afraid of it failing on me and me falling.  Would a band type brace help or benefit me at all or should I just be careful?

Hi Lizzie
It is not a weight bearing bone,so yes i would be carefull.What i would really do is a weight program for your legs,such as leg extensions,leg curls,half squats,wall sits like sitting on a chair for time,leg presses another possibilty.All these will help  with stability and add some insurance current and down the road.I would not use a band or brace,false sence of security.Get into the weights for short and log term stability.Hope this give you some focus Lizzie.

To a successfull
training program
and finish with
no incident.

Answer
Hi Lizzie
The answer is yes,it will be ok.As far as weights go,just ease into it and give yourself 3 days between workouts.The key to good training is patience,consistency,and making the adjustments along the way.Also don't be afraid to take a day off or some easy days.Keep me posted.

All the best
