help me out!!

I tore my acl on December 7th 2008 while playing soccer. As i fell to the ground i heard a massive popping sound. my initial reaction was that it might have been my joint making a noise and so i tried to run but the knee gave way and i realized that i had seriously hurt my self. doctor upon seeing me said that i had a complete acl and lateral meniscus tear and would require a surgery. he also advised me to have an mri to confirm the injury. the mri showed partial and not complete tear which perplexed the doctor as my symptoms were showing complete tear. after the injury i was having great difficulty in bending or straightening my knee.

even though partial tear does not always require surgery the doc advised me arthoscopy to determine the blockage in my knee. on 1st of jan 2009 i had an arthoscopy and the doctor confirmed that the MRI was wrong and that i had a complete grade 3 acl tear as well as lateral meniscus tear. The doctor advised me to delay the acl reconstruction surgery and do intense physio to build my quad muscles. It is said that the more you delay the surgery the better it is post op. after 3 weeks i reached my peek and built my quads to an optimum level. i was on an intense physio program and was squatting more than 75 kgs. since i body build my rehab recovery was faster than what my physiotherapist had expected. according to him i was ready for surgery. So off i went to the doctor who was amazed at my progress. But here is my problem . The doctor through out had said that i would need reconstructive surgery but when he saw me today he was shocked at my recovery and advised me that i should delay the surgery for another 6 months!!!. he claims that the way im progressing i may not need surgery! and that i will be able to play competitive sports. i find that hard to swallow as hours of research on the internet has shown that in order to recover 100 percent from a complete acl tear you need acl reconstruction. i may be an athlete but im sure im not one of the few cases where i dont need a surgery for a complete acl tear. please help me out. im thinking of getting a second opnion.
