Went to a patient seminar sponsored by Dr. Dorr, a big supporter of MAKO, who has been involved in helping the company launch the hip application. Learned the following there:
MAKO is working on the total knee replacement application. Will be "a while" (I sensed a few years) before it comes out, as they are doing the same rigorous testing and studies on it as they have with the partial knee and the hip, including need to get FDA approval. The benefits will be (i) the same reduced invasiveness and thus recovery time as other MAKO procedures, (ii) a quicker operation as with the haptics system there will be less checking and measuring needed after every cut, and best of all (iii) the ability to retain the ACL - which is apparently the "holy grail" of total knee replacements - as currently the ACL has to be removed with a total knee replacement, which leads to a much less natural feeling with the artifical knee! The MAKO is able to save the ACL now, but they just need to do the testing and studies, etc.
