“…The biomechanical consequences of a lateral meniscus root tear in the compartment as described earlier show that the presence of the meniscofemoral ligament is crucial [27,28]. It could be shown that for different angles in knee flexion an avulsion of the posterior lateral meniscal root attachment with a deficient MFL resulted in significantly decreased lateral contact area and increased pressure compared to the intact state.…”

An avulsion of the posterior tibial insertion of the lateral meniscus occurs during rotational distortion of the knee and can be associated with a tear of the anterior cruciate ligament (ACL). We performed a follow-up of 28 patients who, following anatomical ACL reconstruction using the ipsilateral semitendinosus graft, underwent either transosseous repair of the posterior lateral meniscus root (n=14) or no intervention (n=14). The meniscus root tears were classified as Forkel I lesions. All patients were examined 6 months after surgery and undertook scoring using International Knee Documentation Committee Score (IKDC). Comparing the repair group with the no repair group the subjective IKDC 6 months after surgery was 75,72% (±1,019) and 75,56 (±1,058). Regarding the objective IKDC 8 × A (57,1%) and 6 × B (42,9%) could be ascertained in the repair group whereas 6 × A (42,9%), 6 × B (42,9%), and 2 × C (14,3%) scoring could be ascertained in the no repair group. It remains unclear if surgery on type Forkel I PLMRT provides benefits compared to the nonsurgical procedures as in both groups stability might occur. The purpose of this article was to report the outcome of surgical repair of lateral meniscus root tears.

“…However, the biomechanical consequences of posterior root tears of the lateral meniscus significantly depend on the integrity of the meniscofemoral ligaments, which in an intact state sustain the pressure in the lateral knee compartment and preserve the function of the meniscus [92]. Normalization of the contact pressure was achieved by reattaching the posterior root using a tibial ACL tunnel [92]. These observations highlight the complexity of the anatomic relationships and the difficulty in studying their individual and combined effects on knee motion.…”

“…Posterior root tears of the lateral meniscus can be found in about 10 % of patients with ACL tear, and the contact pressure in the lateral compartment increases about 50 % following a complete detachment of the posterior horn [91]. However, the biomechanical consequences of posterior root tears of the lateral meniscus significantly depend on the integrity of the meniscofemoral ligaments, which in an intact state sustain the pressure in the lateral knee compartment and preserve the function of the meniscus [92].

Anterior cruciate ligament (ACL) reconstruction aims to restore the translational and rotational motion to the knee joint that is lost after injury. However, despite technical advancements, clinical outcomes are less than ideal, particularly in return to previous activity level. A major issue is the inability to standardize treatment protocols due to variations in materials and approaches used to accomplish ACL reconstruction. These include surgical techniques such as the transtibial and anteromedial portal methods that are currently under use and the wide availability of graft types that will be used to reconstruct the ACL. In addition, concomitant soft tissue injuries to the menisci and capsule are frequently present after ACL injury and, if left unaddressed, can lead to persistent instability even after the ACL has been reconstructed. Advances in the field of biomechanics that help to objectively measure motion of the knee joint may provide more precise data than current subjective clinical measurements. These technologies include extra-articular motion capture systems that measure the movement of the tibia in relation to the femur. With data gathered from these devices, a threshold for satisfactory knee stability may be established in order to correctly identify a successful reconstruction following ACL injury.
