Is It Safe To Play Soccer After Meniscus Repair?

Hi, i am a 17 year old girl, who recently had meniscus repair on my left knee and my doc. found that i have 2 incomplete hairline fractures in my kneecap, he says there really isnt anything that can be done. The problem is a want to start playing soccer again ( havent been able to since my first injury, torn meniscus. ) and i know with playing soccer, my chances in completely breaking my kneecap is high, i just wanted so advise on what i should do for my knee?
