The phrase "am bundle" is not correct in standard written English.
It appears to be a fragment and lacks context, making it unclear when it could be used.
Example: "I am bundle of joy" could be a corrected version, but "am bundle" itself does not convey a complete thought.
Alternatives: "I am a collection" or "I am a group."
The AM bundle is fixed with a rigid fixation system on the femoral side, and the PL bundle is fixed to tie with the miniplate from the outside femur.
Thus, the center of the AM bundle attachment was 3-dimensionally determined by 2 measured values, the "time" and the distance D. Additionally, to compare the results of the present study with those in the previously reported studies, we superimposed a measurement grid [ 30] onto the lateral view photograph, using the roof of the intercondylar notch as a reference line.
The first specific hypothesis of this study is that the averaged center of the direct attachment of the AM bundle midsubstance fibers may be located at a specific o'clock orientation and at a fixed distance from the POIN in the 3-dimensional clock system.
Interestingly, all patients in the current study had isolated PL bundle injuries, whereas previous similar studies reported that AM bundle injuries were more common than PL bundle injuries [8, 11, 22, 23].
The tibial indicator of the Navi-tip was placed at the center of the PL or AM bundle attachment on the tibia.
The second hypothesis is that the averaged center of the femoral AM tunnel actually created in the patients using the developed technique may be identical to the averaged center of the above-described anatomical AM bundle attachment.
There is a strong possibility that the 3-dimensional clock system is useful in ACL reconstruction surgery to quantitatively locate a femoral tunnel at the center of the AM bundle attachment.
Specifically for the AM bundle reconstruction, we then aimed the femoral indicator at the center of the femoral attachment of the AM bundle, which was determined in the first sub-study, at 90 degrees of knee flexion.
This fact may result in the wide variation of the location of the femoral tunnel created for AM bundle reconstruction reported in the literature [ 8, 15, 28, 34, 35].
Then, based on the results of the first sub-study, we have developed a quantitative technique to insert a guidewire at the averaged center of the AM bundle attachment in anatomic double-bundle ACL reconstruction.
We conducted a prospective evaluation study with patients who underwent anatomic double-bundle ACL reconstruction using the above-described quantitative technique to insert a guide wire for AM bundle reconstruction.
