I dislocated my knee 3 weeks ago and ever since i have lost the mobility of my right knee. it poppped back into place as my friends picked me up.?

Need a consult: It sounds as if you dislocated your patella. Even though the majority of these injuries (especially if a first time dislocation), don't require surgery, patients that receive treatment will have better outcomes than those patients that neglect their knee. A specialist will help make an accurate diagnosis, discuss bracing options and the need for a rehabilitation program.
