Item Arthroscopic study of the knee joint in fetuses(Arthroscopy: The Journal of Arthroscopy and Related Surgery, 2003) Tena Arregui, José; Barrio Asensio, María Del Carmen; Viejo Tirado, Fermín; Puerta Fonolla, Antonio Javier; Murillo González, Jorge AlfonsoPurpose: The purpose of this study was to macroscopically examine the fetal knee joint via arthroscopy. We have attempted to identify and describe the specific characteristics of the fetal knee joint, how it evolves during the last few weeks of intrauterine development, and any possible variations with regard to the adult knee. Type of study: Observational anatomic case series. Methods: We used 20 frozen fetuses with a gestational age of 24 to 40 +/- 2 weeks, obtained from spontaneous abortions. Examination was performed with standard arthroscopic surgical equipment, using a 2.7-mm optical lens. Whenever possible, we tried to use standard arthroscopic portals. Images were obtained for comparison with the adult knee. Results: Suprapatellar and infrapatellar septa were an almost consistent finding. The suprapatellar septum always opened laterally and was intact in the developmentally younger specimens. We found 2 mediopatellar septa. The femoral attachment of the anterior cruciate ligament (ACL) differed in appearance from that of the adult in that it was more ribbon-like. The lateral meniscus had a more spread-out appearance than its adult counterpart, especially in the specimens of a younger gestational age. We were surprised at the easy accessibility of the popliteal hiatus and the clear arthroscopic vision we were able to obtain of the involved structures. Conclusions: To our knowledge, this is the first arthroscopic study to target the fetal knee. The results indicate minimal differences when compared with the adult knee, and for some structures, such as the popliteal hiatus, the anatomy seen was easier to discern than in adult knee arthroscopy.Item Arthroscopic Study of the Shoulder Joint in Fetuses(Arthroscopy: The Journal of Arthroscopic & Related Surgery, 2005) Tena Arregui, José; Barrio Asensio, María Del Carmen; Puerta Fonolla, Antonio Javier; Murillo González, Jorge AlfonsoPurpose: The purpose of this study was to macroscopically examine the fetal shoulder joint using arthroscopy. We attempted to identify and describe the specific characteristics of the fetal shoulder joint, how it evolves during the last few weeks of intrauterine development, and any possible variations with regard to the adult shoulder. Type of Study: Observational anatomic case series. Methods: We used 20 frozen fetuses with a gestational age of 24 to 40 +/- 2 weeks, obtained from spontaneous abortions. Examination was performed with standard arthroscopic surgical equipment, using a 2.7-mm optical lens. Whenever possible, we tried to use the standard arthroscopic portals. Images were obtained for comparison with the adult shoulder. Results: The arthroscopic images of the fetal glenohumeral joint are similar to those of an adult shoulder, with the only differences being those related to the stage of development. In this study we observed no so-called bare spot in the glenoid cavity such as has been described in treatises on the adult shoulder joint. The arthroscopic images of the anterosuperior region of the fetal joint show more highly defined structures than in the adult shoulder, especially the coracohumeral and glenohumeral ligaments. Conclusions: To our knowledge, this is the first arthroscopic study to target the fetal shoulder joint. The results indicate minimal differences when compared with the adult shoulder joint; for some structures, particularly in the anterosuperior region, the anatomy observed was easier to discern than what is observed in adult shoulder arthroscopy. Clinical Relevance: Our study obtained clear images of virgin shoulder joints that had never been subjected to deterioration from wear or other distorting forces. The clarity of these images is useful for locating and identifying structures in the adult shoulder.Item A Lasso-Loop Traction Technique for Arthroscopic Superior Capsular Reconstruction(Arthroscopy Techniques, 2020) Aramberri Gutiérrez, Mikel; Giovanni Tiso D’Orazio; David Gómez-Garrido; Juan-Manuel Antequera-Cano; Murillo González, Jorge Alfonso; Mediavilla Arza, IñakiIrreparable rotator cuff tears (RCTs) cause shoulder pain and disfunction. Management of RCT patients has classically been difficult due to few treatment options. Since Mihata et al. in 2013 introduced the superior capsular reconstruction (SCR) technique as a treatment option, it has become widespread among surgeons, especially for young active patients in whom reverse shoulder arthroplasty is not recommended. With SCR, a reduced humeral head can be maintained and superior displacement is avoided, improving shoulder pain and restoring active shoulder motion. A variety of grafts may be used, but the surgery can be technically complicated. An arthroscopic lasso-loop traction technique for SCR is described here, which simplifies graft shoulder reduction by traction from the anteromedial and posteromedial portals.Item Basic morphological characteristics of coracoid grafts obtained by open and arthroscopic Latarjet techniques: A comparative study(Orthopaedics & Traumatology: Surgery & Research, 2020) Minuesa Asensio, Álvaro José; García Esteo, Francisco; Mérida Velasco, José Ramón; Barrio Asensio, María Del Carmen; Cuadra Blanco, Crótida de la; Murillo González, Jorge AlfonsoBackground: A knowledge of the anthropometric characteristics of the coracoid graft (CG) that can be obtained by the open and arthroscopic Latarjet techniques may be beneficial in the preoperative planning and intraoperative decision making for coracoid osteotomy and transfer. We have not found any study that compared the morphology of the CG that can be obtained from open and arthroscopic Latarjet techniques. The purpose of this study was to verify if the basic anthropometric characteristics of CGs are equivalent. Hypothesis: We hypothesize that the basic anthropometric characteristics of the CGs are similar. Methods: Twenty fresh-frozen human paired cadaveric shoulder specimens that had been randomly distributed in two groups of 10 specimens each were used. Two surgeons, each with experience in performing the open and arthroscopic Latarjet technique, performed these procedures in each of the respective groups (OG, open group; AG, arthroscopic group). A CT scan was performed. Using the volume rendering technique, a metric analysis of the volume, area and length of the CG were performed, evaluated and statistically analysed. Results: There were no significant differences in length (p = 0.162) (mean length, 22.6 mm for OG and 23.6 mm for AG). There were significant differences in the volume (p = 0.031) and area (p = 0.007) of the CG, being lower in the OG (mean volume, 2.8 cm3 for OG and 3.6 cm3 for AG; mean area, 9.9 cm2 for OG and 12.8 cm2 for AG). No significant differences were observed by sex or laterality. Conclusion: The mean lengths of the CGs that were obtained by each technique are equivalent. However, the areas and volumes of the grafts are different, being lower in the open surgery. These differences have not been an impediment to perform the technique. Our results corroborates that consolidation is more related to the preparation and placement than to the anthropometric characteristics of the CG. No significant differences were observed by sex or laterality.Item Combined Double Bundle Anterior Cruciate Ligament Reconstruction and Anterolateral Ligament Reconstruction(Arthroscopy Techniques, 2018) Mediavilla, Iñaki; Aramberri, Mikel; Tiso, Giovanni; Murillo González, Jorge AlfonsoA double-bundle anterior cruciate ligament (ACL) reconstruction associated with an anterolateral ligament (ALL) reconstructions is performed. The semitendinosus and gracilis are harvested. At knee maximum flexion, the anteromedial (AM) femoral tunnel is performed in the AM footprint area. Through the anterolateral portal, the tip of the outside-in femoral guide is placed in the posterolateral footprint area. The guide sleeve is pushed onto the lateral femoral cortex at the ALL attachment. At 110° knee flexion, the posterolateral-ALL tunnel is performed. The tibial ACL tunnel is performed as usual. The tibial guide is placed between the ALL tibial attachment and the tibial ACL tunnel entrance to perform the ALL tibial tunnel. The gracilis graft is introduced from caudal to cranial, achieving fixation with a 6-mm diameter screw (outside-in). The AM femoral fixation is achieved with a suspension device. ACL tibial graft fixation is achieved with a screw. Afterward, the gracilis is passed under the fascia lata to the tibial entry point. A 6-mm diameter screw is placed from the external cortex into the tibial ALL tunnel. The biomechanical advantage of the double-bundle ACL reconstruction with the biomechanical advantage of the ALL anatomic reconstruction is achieved.
