I played soccer 3 weeks after one of my surgeries,
removing a torn piece of meniscus is like taking a stone out of your shoe
its just the swelling and surgery invasion that causes the discomfort

the best part is they would have flushed out any debris in your knee and smoothened the rough surfaces
so your knee will feel clean and like a new oiled chain

how did you injure yours ?
its best to do some basic compound leg exercises to at least try to bring some muscle balance
