Anatomical Landmarks for Hamstring Tendon Harvesting in Anterior Cruciate Ligament Reconstruction

When performing an anterior cruciate ligament reconstruction (ACLR) with hamstrings autograft, one of the most delicate steps is graft harvesting. We will describe different anatomical landmarks that can be used in order to properly ensure that approach and tendon identification is facile. Knowing the anatomy of the ‘pes anserinus’ and different landmarks that can guide us towards harvesting is the goal of this chapter. Our descriptions will be based on existing literature and personal surgical experience. We shall also discuss different options described in the literature that have been used over the years. Knowing the correct anatomy as a surgeon helps improve our technique as such, we deal less local trauma and induce as little scar tissue as possible. Possible complications that can occur during the approach will be also discussed

Preliminary Results in Anatomic All-inside Anterior Cruciate Ligament Reconstruction

Introduction: Anterior cruciate ligament (ACL) rupture is one of the most common lesions in knee traumatology; therefore the number of ACL reconstructions is increasing worldwide. Usually, an anteromedial (AM) accessory portal is required in anatomical positioning of the femoral tunnel, which is not absolutely necessary in this technique. Aim: Assessment of all-inside ACL reconstruction preliminary clinical results with adjustable loops and buttons on both femoral and tibial surfaces. Method: Our prospective study included 28 subjects (19 male, 9 female) with chronic ACL ruptures. The mean age of the study population was 27.72 ± 8.23 years. In all cases ACL reconstruction was carried out with the use of quadrupled semitendinosus auto-grafts with adjustable loops and buttons on the femoral and tibial surfaces and anatomic placement of both tunnels, using an outside-in technique, with flipcutters (Arthrex®). Clinical and radiological evaluations were carried out before surgery and at 3 and 6 months postoperatively, with the Lysholm scoring system, the Tegner activity scale and anterior-posterior and latero-lateral X-rays. Anterior knee laxity was measured in 25° of flexion using a portable arthrometer (RolimeterTM, Aircast®) and maximum manual force. Results: During the final follow-up, the Lysholm score was good and excellent in 27 cases, with a mean Lysholm score of 95.55 ± 4.63; all results were classified as good. The mean preoperative Tegner activity score was 3.46 ± 1.71 (range: 1-7), and the post-operative mean score was 5.75 ± 2.24 (range: 2-10). We found no graft ruptures. Preoperative knee laxity measurements showed a mean displacement of 11.5 ± 3.1 mm and side-to-side differences of 5.6 ± 3.5 mm, while the postoperative measurements at the last follow-up were 6.3 ± 1.54 mm and 2.65 ± 1.86 mm, respectively. Conclusion: Short-term clinical outcomes of all-inside ACL restoration with anatomic placement femoral and tibial tunnels seem to recommend this surgical option, with good subjective and objective results. Additional research will have to prove the long-term success

Anterolateral Ligament (ALL) — Myth or Reality?

Although the anterolateral ligament (ALL) was described a long time ago, recent research shows a lot of interest regarding this structure. There is a high variability concerning its anatomy, especially its capsular/extracapsular situation and insertion sites. There is also some controversy about its ligamentous structure. It seems that it has a biomechanical role in restricting anterior tibial translation and internal rotation. The ALL complex seems to have a clinical significance, and a relationship with the pivot shift has been described. Although there are promising results recently, the surgical techniques of ALL reconstruction, in addition to anterior cruciate ligament reconstruction, have to be further investigated. A precise indication algorithm and patient selection criteria need to be established

Primary Anterior Cruciate Ligament Reconstruction. How Do We Do It?

Anterior cruciate ligament (ACL) tears are frequently seen in current practice mostly affecting the young, active subjects, and usually require ligament reconstruction in order to restore normal knee kinematics. As worldwide interest in anatomic reconstruction grew over the last decade, we have also refined our technique in order to restore the anatomical function as near to the normal as possible. This anatomical restoration concept is believed to prevent the onset of osteoarthritis, which the non-anatomic reconstructions fail to attain. The knowledge gained from the ACL anatomy, function and kinematics has helped in developing the current anatomic methods of reconstruction, which take into account patient anatomy, the rupture pattern, as well as the comorbidities. We present our approach to anatomical single- and double-bundle ACL reconstruction

Novel Surgical Technique for Bone Marrow Lesion — Case Report

Introduction: Bone marrow lesions (BMLs) are commonly described as magnetic resonance imaging (MRI) findings associated with stress injuries or trauma. The presence of BMLs closely correlates with pain and rapid joint deterioration. Case presentation: A 51-year-old healthy man presented to our clinic with severe knee pain due to BMLs. After 3 months of conservative treatment, arthroscopy and subchondroplasty (SCP) of the medial femoral condyle was performed. The IKDC (International Knee Documentation Committee) score improved from 39.9 to 66.7 at 6 months, and to 87.4 at 1 year after surgery. The KOOS (Knee Injury and Osteoarthritis Outcome) score improved from 38.5 to 77.7 at 6 months, and to 92.6 at 1 year after surgery. The Tegner Lysholm score improved from 23 to 80 at 6 months, and to 95 at 1 year after surgery. Conclusion: SCP may provide a viable approach to reduce pain associated with BML, with minimal risk of significant complications

Single- or Double-Bundle Technique in the Anterior Cruciate Ligament Reconstruction — Current Concepts and Review of the Literature

The treatment for anterior cruciate ligament (ACL) deficient knee consists in its surgical reconstruction. There are several available and validated techniques, but there are still numerous questions to be answered concerning the best approach in terms of stability, functional outcome, and avoiding further damage in the knee. This paper sought to analyze the studies published in the literature comparing the outcomes of ACL restoration with single-bundle versus double-bundle techniques. The results demonstrate that even if biomechanical studies find an increased steadiness with double-bundle ACL reconstruction, there seems to be no clinical or functional benefit compared with single-bundle reconstruction

Outcomes in Anterior Cruciate Ligament Reconstruction Surgery

Improving the outcomes in reconstructive surgery of the anterior cruciate ligament (ACL) requires a rigorous and permanent assessment of specific parameters. Therefore, we can increase the degree of reproducibility of the procedure and identify particular aspects in order to achieve an adequate and individualized therapeutic approach for each case. In order to accomplish this goal, the use of complex means (scores) of quantifying results is required. That includes objective means of verifying the parameters in knee surgery, and a subjective evaluation of the patient in order to compare the results

Cross-Cultural Adaptation and Validation of the Romanian Marx Activity Rating Scale for Anterior Cruciate Ligament Reconstruction

Aim: We aimed to translate, cross-cultural adapt and validate the Marx activity rating scale (MARS) of the knee for Romanian patients with anterior cruciate ligament (ACL) injury. Method: The original English form was translated according to guidelines. We included patients with ACL injury undergoing reconstruction in two centers over 3 years. Subjects completed the translated MARS, International Knee Documentation Committee (IKDC) subjective knee form and EuroQol EQ5D. The examining physician completed the Tegner Lysholm scale as an objective evaluation. Re-testing was obtained after one month. We used Spearman`s correlation to evaluate construct validity and reproducibility, Cronbach’s alpha for internal consistency and intraclass correlation for test-retest reliability. Results: We collected valid forms from 99 patients (32.1 ± 8.8 years, 64.6% males) during the preoperative evaluation and 45 were re-tested. Significant, very good correlations were found between the MARS and Tegner Lysholm (Spearman’s r = 0.712, p < 0.0001) and IKDC (Spearman’s r = 0.801, p < 0.0001). Cronbach’s alpha was 0.893 at the initial completion and 0.799 at re-test. The intraclass correlation coefficient was 0.895. Conclusions: The Romanian-translated MARS is a valid, consistent and reliable physical activity outcome measure in patients with anterior cruciate ligament reconstruction
