Introduction: One of the most frequent knee injuries and one that is on the increase, especially in sports, is the anterior cruciate ligament injury. Surgical reconstruction is essential to recover the biomechanics of the knee, provide correct stability and pain-free function, as well as toavoid early degenerative changes. The objective of the present study was to assess the functional recovery of patients undergoing reconstruction of the anterior cruciate ligament by means of ligamentoplasty with semitendinosus- internal rectus tendon and Toggelock system. Material and methods: A retrospective descriptive observational study was designed, which included 29 patients who underwent a ligamentoplasty with internal semitendinosus-rectum and Togglelock system in our Center, during the years 2017-2018. Variables obtained from the clinical history and the Lysholm scale were studied to assess the patients. Results: In total, a sample of 29 patients was obtained, 26 men and 3 women with a mean age of 31.13 years (range 19-53). The most frequently injured knee was the right knee in 17 patients out of 29, with 65% presenting associated injuries. One patient had suffered a tibial fracture operated with an intramedullary nail that altered the final results. The postsurgical score on the Lysholm subjective assessment scale was 86. The mobility of the operated knee showed a minimal reduction in flexion of 6º compared to the non-operated knee that was statistically significant. Conclusion: The results obtained after ACL reconstruction with this technique, using the semitendinosus- internal rectum plasty and the Togglelock system were good-excellent, with a high degree of patient satisfaction, few complications, and notable functional results.

Active Patients

The anterior cruciate ligament (ACL) of the knee is frequently injured, but it has limited healing potential. Surgical reconstruction using soft tissue autografts is often required for active patients. However, about 20–25% of patients have less than satisfactory results and some even developed of osteoarthritis in the long-term. Thus, there is a need for alternative approaches. With advances in functional tissue engineering, healing of the ACL using growth factors and/or bioscaffolds has generated new clinical interests [1].

Anterior Cruciate

Anterior cruciate ligament (ACL) rupture is a common knee injury for athletes. Although surgical reconstruction is recommended for the treatment of ACL ruptures, 100% functional recovery is unlikely. Therefore, the discovery of risk factors for ACL ruptures may prevent injury. Several studies have reported an association between polymorphisms of the collagen XII gene COL12A1 and ACL rupture. Collagen XII is highly expressed in tendons and ligaments and regulates tissue structure and mechanical property. Therefore, we hypothesized that collagen XII deficiency may cause ACL injury. To elucidate the influence of collagen XII deficiency on ACL, we analyzed a mouse model deficient for Col12a1. Four- to 19-week-old male Col12a1-/- and wild-type control mice were used for gait analysis; histological and immunofluorescent analysis of collagen XII, and real-time RT-PCR evaluation of Col12a1 mRNA expression. The Col12a1-/- mice showed an abnormal gait with an approximately 2.7-fold increase in step angle, suggesting altered step alignment. Col12a1-/- mice displayed 20–60% ACL discontinuities, but 0% discontinuity in the posterior cruciate ligament. No discontinuities in knee ligaments were found in wild-type mice. Collagen XII mRNA expression in the ACL tended to decrease with aging. Our study demonstrates for the first time that collagen XII deficiency increases the risk of ACL injury.

Theobjectivewas to compare the effectiveness of isolated anatomical antegrade reconstruction of the anterior cruciate ligament (ACL) with bonetendon-bone autograft (BTB autograft) and in combination with lateral extra-articular tenodesis (LEAT) graft from the iliotibial tract (ITT).Material and methods. We analyzed 187 arthroscopic ACL reconstructions in patients with a Pivot shift test – 3+ degree. We performed an isolated ACL-R in 118 (63.1 %) patients in group 1 and added the LEAT from ITB to it in group 2.Results. According to IKDC-2000: 176 (94.1 %) patients were included in categories A and B, 11 (5.9 %) – in C. Significant differences in these groups appeared 15 months after the operation. According to KOSS: in group 2, the anterior and rotational knee stability, as well as the level of sports activity were higher, and pathological symptoms were less common.Conclusion. LEAT from ITB increases stability and functionality of the knee joint in patients with anatomical antegrade ACL reconstructions with BTB-autograft for terms over 15 months after the operation, and is an economically procedure.

Deficient Knee

A torn anterior cruciate ligament (ACL) is one of the more frequently occurring knee injuries plaguing both athletes and the general population [1]. This injury typically results in severe knee instability thereby limiting the activities the injured is able to perform. Currently, surgical reconstruction is the most common option to restore knee stability and allow the injured subject to return to full functionality (i.e. participation in athletic and recreational activities as desired). However, small populations of individuals who rupture their ACL forego surgery yet still remain fully functional [2]. We hypothesize that these subjects, referred to as “copers”, alter the control strategy of the muscles crossing the knee joint to compensate for their ACL-deficient knee.
