Two segments of PRECICE2 (4.3%; failure of rotational stability) had additional surgery (IIb) (Figure 4).
Because studies have shown that the isometric reconstruction technique couldn't offer sufficient rotational stability for knee joint and may even result in early knee osteoarthritis, single-bundle reconstruction technique evolved from the isometric reconstruction to the anatomic reconstruction (van Eck et al., 2011).

Once cured, the implant provides longitudinal strength and rotational stability.
In our case, prompt halo skull traction for 14 days followed by a rigid collar for the next 6 weeks was sufficient to achieve good and pain-free rotational stability. Magnetic resonance imaging was performed after traction and did not reveal any ligamentous damage.
(12) The newer designs tended to improve rotational stability and reduce lens rotation.
Although reconstructive surgery permits sufficient restoration of the ligament function in sagittal plane [7], it remains limited to the restoration of rotational stability [8, 9].
The DHS and derotation screw (DRS) combination comprises a multiplicity of the screws, usually required for rotational stability of the neck fractures and sliding capacity, which is required for controlled impaction of trochanteric fractures.
[22] reported that the SB reconstruction cannot completely restore anterior knee stability and is ineffective for retaining rotational stability. Adachi et al.
However, the facet joints seem to be critical in maintaining rotational stability. In contrast to complete facetectomy, when medial partial facetectomy is carried out, segment stability is not compromised [7].
