Our study suggests that in ACL reconstruction, the most important fibers to resist tibial anterior displacement attach to the central/proximal part of the femoral attachment this would correspond to the AM fiber bundle [4]. With knee flexion, the contribution of the postero-distal ACL was reduced, thereby further concentrating the load onto the anteroproximal area. This behavior is in line with ACL isometry and fiber length change patterns [16, 27, 28].

Dimensional Stability. Dimensional stabiHty refers to how a fiber changes length under the influence of load or heat. Conventionally described in terms of fiber shrinkage (ASTM D885-64) at a defined temperature, the term has also come to mean time dependent length change or creep. 

Velapoldl et al. (64) used a similar approach but prepared fibers of uniform diameter (5-45 pm) from Inorganic Ion-doped glasses. The fluorescence parameters of these materials can be changed by substituting various Ions, such as Tb , Sm , Eu , Mn, UOj, Cu, and Sn. They show excellent stability under Irradiation using Incident excitation (measurement Imprecision of 1% under continuous Irradiation In the microscope for 24 h) and have a fluorescence flux density proportional to the fiber length. 

The developed sensor was used for ultrathin-film measurement. The reflection spectrum was shifted during the deposition of thin films (e.g., self-assembly of polyelectrolyte layers) onto the sensor end. The reflection between the thin film and the fiber endface was neglected because of their similar refractive indices. As the film increased its thickness, the length of the fiber cavity changed. The amount of change was estimated by the phase shift of the interferogram. The device could also be used as an immunosensor in which the optical thickness changes were used to...

Since the consequences of mechanical energy uptake were disaggregation of fiber bundles, shortening of fiber length and reduction of DP, it is plausible to consider that new surface areas were also created. Accordingly, the change of accessibility of mechanically treated fibers may be observed. The accessibility of mechanically treated fibers was evaluated based on the iodine absorption techniques. Results are shown in Figure 5.
