Unidentifiable Knee Injury-Feels like tendon or ligament laceration

Patient: I injured my knee in a soccer game. another player made glancing but direct contact with the front left side of my right knee. there was a large bruise which has since healed, but pain remains in the knee when i pull the skin around the injury site accidentally. if i am bending down on my knees and shift forward, for example, there is a shooting pain, much like the pain one feels from stretching a healing cut, around the injury site. i can only describe it as a tightness. what has happened to my knee and what can i do?
