How do I strengthen my knee after surgery?

Firstly the best thing to do would be to vist a professional who specilises in rehabilitation such as and Acredited Exercise Physiologist (www.essa.org.au) or a physiotherapist.

Outside of that though it is not just about strenghening.  You also need to include balance exercises such as wobble board training, or even just balancing on one foot and having people pass balls to either side of you.  This will increase the co-contraction of the muscles around you knee, which inturn will increase your stability.  Try including this in your program and see how you go. 

Hi, totally agree with both answers. It's not until we have that we appreciate the bodies ability to co-ordinate and move. Any exercise or movement  requires boh spinal stability and joint stability to move with balance and injury free. Movements like running that are very repetitive in nature, require great technique, balance and coordination to ensure injuries do not occur. People will get coaches for just about any other activity Except running. 

My advice would be to seek advice from a exercise physiologist. They should be able to prescribe a exercise routine to improve both knee and spinal, strength as well as balance. They should also be able to advise you'll  low impact activities to help not only shed the weight but reduce the strain on the knee once you progress to more complex and higher impact activities.

You have had significant knee surgery for, what I imagine was a re-occuring dislocating knee cap.  Generally, return to running is recommended at 4-6 months.  This allows time for the lower limb fracture you have been given (re-attachment of the tibial tuberosity) to be properly knitted.  It sounds like you are doing well if you are walking about and not noticing a limp etc.  However, it really is difficult to provide a complete answer to this question without actually assessing the knee.  The fact you have also had a lateral release means you might have developed scar tissue in the lateral retinculum (the tissue on the outside of the knee) and this might need some manual work to release it.  I would suggest going to see a sports physiotherapist.  This is the kind of thing we are trained to treat.  We can provide advise on progressing strength training about the lower limb and also do some manual work on scar tissue if required.  Good luck…..jono

Lots of valuable advice here, you have had a major reconstruction of your leg so supervision would be safer than taking risks on your own. Even on a stationary bike you need someone to guide you on alignment - if you're cycling in traffic it would be harder to maintain this. An Experienced Physiotherapist local to you would liaise with your surgeon and ensure the optimal strenghtening programme to help you shed those unwanted kilos while ensure the best possible results from your surgery. You do need to be a patient patient - not easy when you've been out of action for months already.  Good Luck :)

After surgery, the muscles around your knee will be noticeably weaker. The best way to start strengthening your knee would be to start with a hydrotherapy program (water based exercises) and hopping on an exercise bike starting with gentle resistance and gradually increasing the resistance and time spent on the bike as you get stronger. A physiotherapist will be able to correctly assess what stage of your rehabilitation you are at, and put together an appropriate strengthening and proprioception program. Strengthening through specific muscle groups around your hip and knee will be very important considering the type of surgery you have had and your physiotherapist will be able to show you how to correctly perform and progress these exercises to get you moving again.
