Partial ACL tear - no surgery

[syamir]

Hi guys,

i'm 22 and a very active sportsmen.. i play rugby (club level), football/futsal (college level) and tennis/badminton (occasional)..

He asked me to do some self physio such as cycling and swimming for rehabilitation. a need for immediate surgery was not neccesary in late nov 2011 i partially torn my ACL at rugby training while i was side stepping.. went to see the specialist & got myself an MRI scan.. the doctor confirmed that it was a partially torn ACL..

an immediate surgery isnt necessary.. since i'm still doing my internship, the specialist gave me time to regain strength and rehab my knee before the next check-up.. if there is still signs of instability, a full reconstruction may be required.. after 2 months of occasional swimming, cycling & weights training, i do have full motion of my knee but it still hurts at times..

My questions are:
1) can anyone define "instability"?
2) is there much benefit of "arthroscopy"? *arthroscopy: trimming out the torn portion
3) after rehab, the chances of turning a partial tear into a full tear is there. does strapping tape help in anyway during sports?
4) after a complete reconstruction, does the possibility of the same injury increase, maintain the same or decrease? Is the new ACL stronger, the same or weaker than the original ACL?
5) trough the thread, there are contradictions between PTs and patients.. PT says use what u hv left (use it until fully torn with possibility of MCL injuries as well), patient says straight reconsruction.. can anyone verify who to follow?

hope someone can help out.. really want to get back on to the field.. a young man that really wants to get back on his feet..
