When ......I did my knee the first [ the triad .....just like my little bro Ivan ] time in college ..........I was sent to the 49ers ortho Dillingham and his partner Art Ting [ they used to have their own clinc ,but have since split .......Dillingham is still the 49ers guy and Ting is the San jose Sharks guy .....they both did me the first time because my knee was blown up inside so bad ] I was told the same as Ivan ........and went patella as well.............back then the procedure was not as good and I actually spent five days in the hospital .......and slept in a cpm machine for a 3 month period [ which sucked big time ] and it was an 18 month recovery , but came back and played a year later [ but shouldnt have ] .........these two were considered the best.........so when I did the same knee in the pros, I was even sent across country to use these guys instead of the team ortho.......The second time .......my grafts didnt hold as well , which is common when doing it twice in the same knee with in a couple of years apart ...........there ended up with too much play in the knee and it hurt me on the feild ...........I was released during my recovery and picked up by the Bears [ I remember being excited ......I was being projected by their coaches as a starter and knew i would at least get a fair shot at it ] When I arrived , I was worked out and was treated like gold ......I was in great shape and was really stoked .......then they call me in to take my physical ........and they begin with all the basic tests and questions ............and then the doc gives me , " so you are coming off a second ACL to the same knee ? " I say," yes sir " . AND he goes , " I see , lets take a look . " He pulls on it and moves it through some motions , then pulls on it again .........and just nods his head in dissapointment ......." this is no good " and then he leaves ........I waited for what seemed to be forever and then some nobody assistant aid comes in ........" we are done ,lets go get your stuff back at the hotel , time to go home ." I was amazed , " and asked what was happening ...........the guy just goes," you failed your physical , too much play in that knee , sorry " I was ," let me take an mri and see what is going on ,let me rehab /workout some more , come on ." The guy just sayes , " Look son ,there is too much play in your knee , give it up , you are done .......forget about it . " They took me to the airport and dropped me off like garbage to wait on stand by until I could get a flight home ......As far as my rec .........patella being that he is an athlete........It is a longer recovery and harder too ........but the first time ,I was golden ....the second time, I damaged some nerves and never got my quad to fully catch up to the other one [ this why my back troubles started ] .....I get some tendinitous.......and strength came back close ,but never quite the same ......I cant flex my quad the same either ,,,,,,,,it flexs but , does not show close to the seperation as the other one ........but patella is what most of the top pros do for sure ............but who knows after what happened to me .....maybe Kaizer is right .......lol
