- Development of a Fresh Osteochondral Allograft Program Outside North America(2016) TIRICO, Luis Eduardo Passarelli; DEMANGE, Marco Kawamura; SANTOS, Luiz Augusto Ubirajara; REZENDE, Marcia Uchoa de; HELITO, Camilo Partezani; GOBBI, Riccardo Gomes; PECORA, Jose Ricardo; CROCI, Alberto Tesconi; BUGBEE, William DickObjective. To standardize and to develop a fresh osteochondral allograft protocol of procurement, processing and surgical utilization in Brazil. This study describes the steps recommended to make fresh osteochondral allografts a viable treatment option in a country without previous fresh allograft availability. Design. The process involves regulatory process modification, developing and establishing procurement, and processing and surgical protocols. Results. Legislation: Fresh osteochondral allografts were not feasible in Brazil until 2009 because the law prohibited preservation of fresh grafts at tissue banks. We approved an amendment that made it legal to preserve fresh grafts for 30 days from 2 degrees C to 6 degrees C in tissue banks. Procurement: We changed the protocol of procurement to decrease tissue contamination. All tissues were procured in an operating room. Processing: Processing of the grafts took place within 12 hours of tissue recovery. A serum-free culture media with antibiotics was developed to store the grafts. Surgeries: We have performed 8 fresh osteochondral allografts on 8 knees obtaining grafts from 5 donors. Mean preoperative International Knee Documentation Committee (IKDC) score was 31.99 +/- 13.4, improving to 81.26 +/- 14.7 at an average of 24 months' follow-up. Preoperative Knee Injury and Oseoarthritis Outcome Score (KOOS) score was 46.8 +/- 20.9 and rose to 85.24 +/- 13.9 after 24 months. Mean preoperative Merle D'Aubigne-Postel score was 8.75 +/- 2.25 rising to 16.1 +/- 2.59 at 24 months' follow-up. Conclusion. To our knowledge, this is the first report of fresh osteochondral allograft transplantation in South America. We believe that this experience may be of value for physicians in countries that are trying to establish an osteochondral allograft transplant program.
- Regarding ""The Effect of Combined Anterolateral and Anterior Cruciate Ligament Reconstruction on Reducing Pivot Shift Rate and Clinical Outcomes: A Meta-analysis""(2021) SAITHNA, Adnan; HELITO, Camilo P.; CARROZZO, Alessandro; KIM, Jin Goo; SONNERY-COTTET, Bertrand
- Combined All-Inside Anterior Cruciate Ligament Reconstruction With Semitendinosus Plus Anterolateral Ligament Reconstruction With Intact Gracilis Tibial Insertion and Transtibial Passage(2023) SANTOS, Daniel Almeida Neto e; FARIA, Jose Leonardo Rocha de; CARMINATTI, Tiago; PAULA, Rafael Erthal de; PADUA, Vitor Barion Castro de; PAVAO, Douglas Melo; LAPRADE, Robert F.; HELITO, Camilo PartezaniThe indications for combining anterior cruciate ligament reconstruction with anterolateral ligament recon-struction have increased considerably in recent years since several anatomical, clinical, and biomechanical studies have proven the importance of the anterolateral periphery in knee rotational stability. Much is still being discussed on how to combine these techniques in terms of which grafts and fixation options to use, as well as avoiding tunnel convergence. This study aims to describe anterior cruciate ligament reconstruction with a triple-bundle semitendinosus tendon graft all-inside technique combined with an anterolateral ligament reconstruction maintaining the gracilis tendon insertion on the tibia, using independent anatomical tunnels. With this, we were able to reconstruct both using only hamstring autografts, reducing morbidity in other possible donor areas, in addition to allowing stable fixation of both grafts without tunnel convergence.

- Anterolateral ligament of the knee: a step-by-step dissection(2019) LIMA, Diego Ariel de; HELITO, Camilo Partezani; DAGGETT, Matthew; MONTEIRO NETO, Francisco Magalhaes; LIMA, Lana Lacerda de; LEITE, Jose Alberto Dias; CAVALCANTE, Maria Luzete CostaBackgroundThe number of studies and clinical interest in the anterolateral ligament of the knee (ALL) has grown in recent years. A meticulous and accurate ALL dissection is vital in anatomic and biomechanical studies, and a standardized technique is not yet established. As such, the aim of this study was to describe a step-by-step ALL dissection technique that could help authors consistently identify the ALL.MethodsTwenty knees from frozen adult cadavers, with no preference for sex or age, were included in the study. All the cadavers were dissected using the same technique to determine the incidence of the ALL.ResultsA transverse incision is performed in the iliotibial band (ITB), around 10cm proximal to the topography of the lateral epicondyle of the femur. Next, the ITB undergoes anterograde blunt dissection until its insertion at Gerdy's tubercle in the tibia. Maintaining biceps femoris insertion, a dissection is performed anteriorly to it, until the lateral collateral ligament (LCL) is found. Using the LCL, internal rotation and 30 to 60 degrees flexion as references, the ALL can be located in the anterolateral topography of the knee, with its origin near the lateral epicondyle (proximal and posterior) and insertion between Gerdy's tubercle and the fibula (4.0mm to 7.0mm below the tibial plateau), expanding to the lateral meniscus (between the body and anterior horn), exhibiting a mean length of 4.00.4cm and mean width of 5.5 +/- 0.8mm.Conclusions p id=Par4 The present article describes an effective and reproducible ALL dissection technique that made it was possible to identify the ligament in 100% of the cases in the present study.
- High Prevalence of Anterolateral Ligament Abnormalities on MRI in Knees With Acute Anterior Cruciate Ligament Injuries(2019) FERRETTI, Andrea; MONACO, Edoardo; REDLER, Andrea; ARGENTO, Giuseppe; CARLI, Angelo De; SAITHNA, Adnan; HELITO, Paulo Victor Partezani; HELITO, Camilo PartezaniBackground: Broad variation in the reported rate of magnetic resonance imaging (MRI)-detected abnormalities of the anterolateral structures of the anterior cruciate ligament (ACL)-injured knee suggests a lack of reliability that has limited the use of MRI in clinical decision making. Purpose/Hypothesis: The aim of this study was to use MRI to determine the prevalence and spectrum of abnormalities of the anterolateral structures in acute ACL-injured knees, using the contralateral uninjured knee as a reference. We hypothesized that MRI evaluation of the acutely injured knee (using the uninjured knee as a reference) would allow reliable identification of abnormalities of the anterolateral structures. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: Patients with acute ACL injury underwent MRI scan of both knees. Images were evaluated by 3 observers. Inter- and intraobserver reliabilities were determined for MRI parameters of anterolateral ligament (ALL) injury by use of the kappa (kappa) test. Univariate and multivariate analyses were conducted to test associations between ALL abnormality and associated injuries. Results: A total of 34 patients were evaluated. Of these, 30 patients (88.2%) had at least 1 ALL abnormality in the ACL-injured knee (increased signal: n = 27[79.4%]; increased thickness: n = 15[44.1%]; tapering: n = 7[20.6%]; irregularities in the path of the ALL fibers: n = 21[61.7%]). Asymmetries of the genicular vessels were observed in 21 patients (61.7%). ALL abnormality was significantly associated with lateral joint capsular tears (P <.001). No correlation was found between ALL lesions and iliotibial band lesions (P = .49). Inter- and intraobserver reliabilities were very good concerning ALL signal changes and femoral and tibial bone bruises (kappa coefficient, 0.81-1). Conclusion: MRI evaluation of the ALL was associated with good and very good inter- and intraobserver reliabilities, and it demonstrated abnormalities of the ALL in the majority of acutely ACL-injured knees. The index of suspicion for ALL injury should be elevated by the presence of lesions of the lateral capsule. This suggests that the ALL is part of a wider area of the lateral capsule that is often injured simultaneously in an acute ACL tear.

- Anterolateral Ligament Expert Group consensus paper on the management of internal rotation and instability of the anterior cruciate ligament - deficient knee(2017) SONNERY-COTTET, B.; DAGGETT, M.; FAYARD, J.-M.; FERRETTI, A.; HELITO, C. P.; LIND, M.; MONACO, E.; PADUA, V. B. C. de; THAUNAT, M.; WILSON, A.; ZAFFAGNINI, S.; ZIJL, J.; CLAES, S.Purpose of this paper is to provide an overview of the latest research on the anterolateral ligament (ALL) and present the consensus of the ALL Expert Group on the anatomy, radiographic landmarks, biomechanics, clinical and radiographic diagnosis, lesion classification, surgical technique and clinical outcomes. A consensus on controversial subjects surrounding the ALL and anterolateral knee instability has been established based on the opinion of experts, the latest publications on the subject and an exchange of experiences during the ALL Experts Meeting (November 2015, Lyon, France). The ALL is found deep to the iliotibial band. The femoral origin is just posterior and proximal to the lateral epicondyle; the tibial attachment is 21.6 mm posterior to Gerdy’s tubercle and 4–10 mm below the tibial joint line. On a lateral radiographic view the femoral origin is located in the postero-inferior quadrant and the tibial attachment is close to the centre of the proximal tibial plateau. Favourable isometry of an ALL reconstruction is seen when the femoral position is proximal and posterior to the lateral epicondyle, with the ALL being tight upon extension and lax upon flexion. The ALL can be visualised on ultrasound, or on T2-weighted coronal MRI scans with proton density fat-suppressed evaluation. The ALL injury is associated with a Segond fracture, and often occurs in conjunction with acute anterior cruciate ligament (ACL) injury. Recognition and repair of the ALL lesions should be considered to improve the control of rotational stability provided by ACL reconstruction. For high-risk patients, a combined ACL and ALL reconstruction improves rotational control and reduces the rate of re-rupture, without increased postoperative complication rates compared to ACL-only reconstruction. In conclusion this paper provides a contemporary consensus on all studied features of the ALL. The findings warrant future research in order to further test these early observations, with the ultimate goal of improving the long-term outcomes of ACL-injured patients.
