Operation recovery

My female Shih Tzu cross had a luxating patellar operation, and I have been restricting her exercise ever since so that she recovers well. 

What is the best aftercare for a knee operation like this? I haven't seen much of an improvement in her walking yet, so I don't know if her muscles are fully recovered or not. Has anybody had a similar experience?

How do I keep my Lab cross puppy from going crazy in the time after she has been spayed?

She's awful without a good walk!
