Hi Rajah,

i do completely agree with neurospast, but supposing that the patient has had a surgery with the quadriceps tendon graft, and the lesion is more localized to ACL alone, the first thing that has to come in to your mind is that, the role of ACL is to prevent anterior translation of tibia, and quadriceps function is also the same, (basically when you extend at your knee your tibia translates anteriorly),,


so some texts suggests that the knee kept in 30 degree flexion and to start isometric quads, you can start that as early as the second to third day post post op*(provided that the surgeon gives consent)

the problem with these post surgery rehabilitation is that the surgeon should give the pass for any thing, in the hospital where i work , we have three units, ortho 1 , 2 and 3. ortho 1 will want to start the quads exercises with knee in 30 degree flexion but ortho 3 will want to do it in full extension, both the units gives good results,

so its basically the confidence the surgeon has in his surgery and ofcourse the associated complications,

i would suggest start with isometrics and gradually progress on according to the patients response

cheers
