the meniscus is also torn, and the coverage of the patient's insurance. A study has shown in 2016 that metropolitan areas, of at least one million residents, located on the western coast of the United States of America and areas like Minnesota, Indiana, and Michigan were more expensive than the East and South East coast of the United States. Another study, conducted by Baylor University, found that ACL reconstruction procedures using the bone-patella tendon-bone technique took 2.5 hours longer than using a hamstring graft. The operation room costs and hospital charges for that amount of extra time came to about $1,580 more expensive. This also applies to having a torn meniscus during the procedure. Fixing the torn cartilage will increase the procedure time, increasing cost. Insurance plays the biggest role in cost for an ACL reconstruction since that it will be covering majority of the costs. The coverage of a patient's plan, deductibles, and insurance company will determine how much the patient will pay in copays. Despite the complexity of the procedure and numerous doctor's visits involved, 80–90% of patients who have had the surgery said they had favorable results.
