Did : Did you have the penetrating wound to your knee address to see if it got to the joint? Where any x-rays taken? You don't give enough information for a clear answer.

Kneecap joint.: You may have bruised the kneecap joint, which can take 6-8 weeks to clear up. You should see a non-surgical sports medicine specialist, who can make an accurate diagnosis and treatment plan.
