ACL Reconstruction & Osteoarthritis Risk Factors

Peruse through HERE at your own leisure. 
This is probably one of the better comprehensive articles on the process as a hole, differences and problems associated with different times of reconstruction, and then risk factors associated with recovery and onset of Osteoarthritis:

Key risk is not the ACL reconstruction surgery itself, but 3 factors:

Basic Overview:
waiting more than 6 months to have the surgery, an acute severe injury (such as impact to knee), accompanying injury to the meniscus/other major structures at the time of injury, & waiting more than 6 months to have the surgery,
--
It was previously thought that the surgery itself, and perhaps the patellar tendon bone graft reconstruction process were the culprit in the onset of Osteoarthritis within 6-10 years of the surgery/reconstruction. The problem with that if A then B = C logic is that if you take an individual who has the patellar tendon bone graft, they are also the individual most likely to return to sport/perfomance based lifestyle and therefore also at more risk of Osteoarthritic development anyway, not necessarily because of the type of graft/reconstruction chose when compared to someone who has the surgery but then does not return to sport, for example. Previous studies also did not try to rule out the presence of time between major/acute injury and surgery, nor did they look to rule out the presence of other ligament damage at the time of injury as a consideration.

When comparing a cross section of different injury scenarios, reconstruction options, and timelines, the perfect storm of factors most likely to produce the onset of Osteoarthritis within 6-10 years of surgery is the following:
1) injury to meniscus and other structures in addition to ACL at time of injury
2) impact/acute injury as definite source of injury (as opposed to chronic pain/undetermined injury which then leads to/suggest the following risk factor)
3) waiting 6 months or more to have the reconstruction from time of injury
