Extracorporeal membrane oxygenation (ECMO) therapy in patients with coronavirus disease 2019 (COVID-19) has a low frequency of use, and thus pathological findings in such patients are valuable. In this case report, a 62-year-old man with a history of hypertension presented with a runny nose. After an at-home COVID-19 positive test, he developed dyspnea and fever. Once admitted to our hospital, his oxygenation worsened, and ECMO was initiated. He died from respiratory failure 69 days after ECMO induction. Macroscopically, the lungs gained mass, were partially consolidated, and were airless. Histological analysis revealed diffuse bronchial epithelial metaplasia and adenoid metaplasia in the alveolar epithelium. Although the lung parenchyma was partially preserved, there was organizing and fibrosis that filled pulmonary alveolus due to COVID-19 and changes resulting from disuse and long-term ECMO.61-year-old man, with a history of years of unknown etiology bronchiectasis, with chronic bronchial infection by Burkholderia multivorans, who received treatment with a double lung transplant on 08/20/2020. Persistent positive cultures of Burkholderia multivorans after transplant in respiratory samples was observed, and treatment with inhaled tobramycin 300 mg/12 hours was started. One month after treatment, a significant worsening of renal function was observed, which was already altered, and toxic levels of tobramycin were measured in blood samples 12 hours after the last inhaled administration. After stopping treatment, kidney function returned to its baseline values.Medial quadriceps tendon-femoral ligament (MQTFL) reconstruction for prevention of recurrent patella dislocation is an alternative to medial patellofemoral ligament (MPFL) reconstruction. Because the reconstruction graft attaches to the quadriceps tendon, no patella drill hole is required, thereby eliminating iatrogenic fracture risk. The procedure remains anatomically accurate and early results are comparable to MPFL reconstruction for preventing patella dislocation. The MQTFL reconstruction graft is brought up under the vastus medialis obliquus distal to the patella apex, such that its orientation is directed toward the medial patellofemoral complex (MPFC) midpoint, also known as Tanaka's point. The graft is then secured by looping it around the vastus medialis and rectus femoris tendons, after which optimal graft length is easily established by cycling the knee, after which it is sutured securely into the deep quadriceps tendon precisely at the anatomic midpoint of the MPFC. Anatomic reconstruction of the MQTFL-in which graft orientation is crucial-confers reliable patellofemoral joint stability in the surgical treatment of patients with recurrent patella dislocations.Abdominal compartment syndrome (ACS) is a rare but potentially fatal complication that can occur during hip arthroscopy. This usually occurs as a result of arthroscopic fluid passing into the retroperitoneal space through the psoas tunnel. From the retroperitoneal space, the fluid can then enter the intraperitoneal space through defects in the peritoneum. Previous studies have identified female sex, iliopsoas tenotomy, pump pressure, and operative time as potential risk factors for fluid extravasation. We present a method to measure intraoperative fluid deficit during hip arthroscopy to alert surgeons to possible ACS. Our proposed technique requires diligent intraoperative monitoring of fluid output through various suction devices, including suction canisters, puddle vacuums, and suction mats. The difference is then calculated from the fluid intake from the arthroscopic fluid bags. If the difference is greater than 1500 mL, then the anesthesiologist and circulating nurse are instructed to examine the abdomen for distension every 15 minutes. This, combined with other common symptoms such as hypotension and hypothermia, should alert the surgical team to the development of ACS. Despite limitations to this technique, this approach offers an objective method to calculate intra-abdominal fluid extravasation.The meniscus comma sign has been described for displaced flap tears of the meniscus. These meniscus tears are displaced into the tibia or femoral recesses and can be often difficult to diagnose intraoperatively. We describe the technique of diagnosis and treatment of a large displaced lateral meniscus flap tear, presenting as a meniscus comma sign. The identification of the meniscus comma sign on consecutive magnetic resonance imaging (MRI) cuts suggest a flap tear of a significant size that indicates reparability. The technique would be to lift the meniscus flap from the meniscotibial recess, reduce it and then repair it with an all-inside meniscus repair or by hybrid meniscus repair techniques.Biplanar open wedge high tibial osteotomy (OWHTO) has become common since the introduction of OWHTO-specific plates. However, the management of soft tissues, including skin, the pes anserinus, and the superficial medial collateral ligament (sMCL) release vary among surgeons. We introduce an OWHTO methodology that avoids pes incision and repair, uses bone substitute insertion into the opening gap and includes management of soft tissues to minimize complications. check details We adopted a reversed curved oblique incision to reduce the risk of saphenous nerve injury. We avoided pes incision, taking advantage of its posterior component force to allow it to function as a compressor of the ascending osteotomy site. The proximal component force of the pes provides compression between the bone substitute insertions and the proximal/distal cortices. This allows postoperative weight bearing to be distributed to the substitute, which may reduce the risk of implant failure. The sMCL is detached from the distal tibial attachment without cutting, enabling its return to its original position underneath the pes and to be repaired. This sMCL release with complete pes preservation may reduce the risk of deep infection or medial laxity during total knee arthroplasty conversion, and further reduce the risks of OWHTO.Wrisberg variant discoid lateral meniscus (DLM) is a congenital anatomic variation of the meniscus in the knee joint, which is an uncommon type of the DLM. We present a surgical technique in a case of symptomatic Wrisberg variant DLM. To improve the instability due to the lack of the posterior attachment of meniscotibial ligament, the posterior portion of DLM was attached to the insertion site of normal LM posterior root using pull-out repair technique. In addition, a longitudinal tear from the anterior to the middle portion of DLM was repaired with outside-in and inside-out techniques. Finally, a capsulodesis using knotless anchors was performed from outside of the joint to prevent the meniscus extrusion after the surgery. Knee symptoms such as pain, catching, and ROM restriction disappeared at 3 months after the surgery. Postoperative magnetic resonance imaging showed a slightly sharpened shape of the DLM, and the attachment of the posterior portion of the DLM was observed. Longitudinal tear of the DLM was healed without cleavage. This procedure is useful to improve the symptoms of the knee joint with Wrisberg variant DLM and to preserve the function of the meniscus.Acromioclavicular joint separation is a common shoulder injury. Grade I and II separation may be treated nonoperatively, whereas higher grades tend to require surgical intervention. Various repair techniques have been described in the literature, with no consensus on the gold standard. This Technical Note describes our use of a graft-passing instrument to pass suture under the coracoid during an anatomic reconstruction of both the acromioclavicular and coracoclavicular ligaments. Although this approach is technically challenging, it avoids coracoid drilling and requires smaller-diameter clavicle and acromion drilling. Furthermore, using suture instead of graft material increases the cost-effectiveness of the procedure.In comparison with the single-bundle technique, double-bundle anterior cruciate ligament (ACL) reconstruction has proven its superiority regarding biomechanical studies and clinical outcomes in both rotational knee stability and anterior translation function. However, the complexity and risk of complications remain a great concern for the orthopaedic surgeon performing double-bundle ACL reconstruction. We present a simplified double-bundle ACL reconstruction by the 3-inside technique with 2 suspension buttons and 1 interference screw. The semitendinosus tendon is tripled to be the anteromedial (AM) bundle, whereas the gracilis is doubled for the posterolateral (PL) bundle. We perform a 3-socket approach with an inside-out femoral tunnel for the AM bundle, an outside-in femoral tunnel for the PL bundle, and a retrograde tibial socket for the tibial bundle. Thus, this technique is, simply, a combination of 2 procedures one single all-inside method (for the AM bundle) and one outside-in method (for the PL bundle), with which most arthroscopic surgeons are familiar. The AM and PL bundles are fixed at 30° and 45°, respectively, using 2 suspension buttons and 1 interference screw. Our simplified technique could reduce surgical costs and minimize complications while maintaining isometric position and appropriate graft size for each patient.Post-traumatic hallux valgus, a turf toe variant, is a rare, yet limiting injury. link2 According to the literature, the deformity has been associated with acute medial collateral ligament tears, turf toe variant injuries, Lisfranc injury patterns, and first metatarsal fractures. There have been few documented cases of post-traumatic hallux valgus secondary to medial collateral ligament tears, and the treatment has been variable. Some authors have described direct end-to-end repair of the ligament to address the deformity, while others have described a modified McBride bunionectomy involving a Silver bunionectomy, lateral soft tissue release, and medial capsular and ligamentous repair. We propose a modified technique similar to the modified McBride bunionectomy, however, with the use of an all-suture anchor in the medial capsular and ligamentous repair. Our belief is that the all-suture anchor will allow for a stronger repair that will meet the physical demands of everyday ambulation and athletic participation. link3 We used this technique in an individual who had evidence of a medial ligamentous complex injury of the hallux on MRI and failed conservative management. Postoperatively, the patient is immobilized until they can begin working on range of motion, strengthening, and finally to achieve return to full activity and sports.The subscapularis muscle and its tendon are of major importance in the kinematics of the glenohumeral joint. Therefore, a diligent repair of subscapularis tears is essential. We describe our reliable standardized arthroscopic suture bridge technique to repair subscapularis tears under intra- and extraarticular visualization and with preservation of the "comma sign." This technique provides excellent exposure of the subscapularis tendon, allows its complete release in the subcoracoid space and ensures a safe and stable repair.Acetabular rim fractures can accompany patients with femoroacetabular impingement. Frequently, the acetabular rim fracture is excised. However, if the osseous fragment of the acetabular rim fracture is large enough to result in instability, then the acetabular rim fracture should be reduced and secured with internal fixation. The purpose of this technical note was to describe the arthroscopic technique of internal fixation of an acetabular rim fracture.
