“…Recently, Zantop [41] has underlined that antero-lateral rotational instabilities could increase tibial translation on ACL-deficient knees; therefore, the lateral plasty could be a valid solution in these combined and often underestimated lesions.…”

The objective of this study was to quantify, in vivo, the reduction of knee laxity obtained by an extra-articular procedure, added to hamstring single-bundle (SB) anterior cruciate ligament (ACL) reconstruction in controlling coupled tibial translation during the Lachman and drawer tests. Twenty-eight patients were evaluated with a computer-assisted kinematic evaluation protocol; patients with associated ligament tears or meniscal damages were not included in the study. All patients underwent an hamstring ACL with an additional extra-articular procedure. During the intervention, tibia was tracked during the Lachman and drawer tests with ACL-deficient knee, after SB fixation and after extra-articular plasty fixation, performed with the remnant part of the hamstring tendons, from end of lateral condyle to Gerdy's tubercle. Statistical analysis was performed to see whether there was a difference in knee laxity after the tests in the three steps. At 30 degrees , the SB graft reduces AP translation of about 5 mm (P < 0.05) while the extra-articular procedure controls lateral tibial compartment, reducing translation by 1.6 mm (P < 0.05). At 90 degrees the SB graft reduces AP translation more in the lateral compartment (P < 0.05), while the extra-articular procedure contributes in controlling tibial translation reducing laxity by 1 mm (P < 0.05) in both compartments. Result shows that, in vivo, the addition of an extra-articular procedure to single-bundle ACL reconstruction may be effective in controlling coupled tibial translation during the Lachman test and reduces AP laxity at 90 degrees of flexion.

“…The lateral patellofemoral ligament, popliteus tendon, popliteofibular ligament, and fabellofibular ligament have all been described in detail [3,[9][10][11][12][13]], but to date descriptions of the attachments of the LCL remain incomplete in the published literature.…”

In the published literature as well as in the most commonly used textbooks, the lateral collateral ligament (LCL) is described as having 1 attachment at the lateral epicondyle of the femur and another at the head of the fibula. In this article, we reconsider the attachments, the length of the LCL, and the tissues surrounding the LCL by presenting our anatomical observations and by reviewing the literature. Our results have shown that the LCL is not only attached to the lower part of the lateral epicondyle of the femur, but also extends to the upper part of the lateral epicondyle. The attachment of the LCL on the fibula is enclosed by 2 insertion points of the biceps femoris tendon. The average length of the LCL in 71 knees was 51.4 mm. There is an "incomplete gap" on the LCL that is interrupted under the tendon of the biceps femoris.

“…In the recent years, there has been increasing interest in extra-articular procedures because biomechanical studies have shown that additional injury to the lateral capsular structures increases anterior rotational instability significantly (Diermann et al 2009;Zantop et al 2007b).…”

Anatomical ACL replacement with medial portal drilling and footprint reconstruction is the technique of choice for patients with symptomatic instability after an ACL rupture (non-coper). The gold standard is the anatomic single-bundle reconstruction with mid-position placement of the tunnel. For patients with a large attachment area, a double-bundle technique could be indicated. Graft options for anatomical ACL reconstruction are the hamstrings, patellar tendon, or the quadriceps tendon with or without bone blocks. Graft choice depends on the individual demands and needs of the patient. A large group of patients can be treated successfully by all three autografts or by nonirradiated allografts. Some subgroups, however, may profit from a specific graft choice. Age, gender, activity, sports, profession, and religious habits should be considered.
