Although patellar dislocation is a knee disorder prevalent in adolescence and young adults, the evaluation and treatment of patients are complex and even enigmatic. Much of the literature fails to provide a detailed description of patient management. The purpose of this study is to introduce a method for the evaluation and treatment of patellar dislocation. This Technical Note will help guide clinicians in the clinical evaluation of patients and formulation of treatment plans.Avascular necrosis is a relatively common entity that affects the proximal humerus and can lead to substantial morbidity. It often occurs in younger patients for whom the traditional treatment of shoulder arthroplasty is not optimal. Fibular strut grafting to prevent humeral head collapse has been described as a viable treatment option. However, it is technically challenging to direct the fibular strut graft into the center of the bony infarct, where it will be most effective. This paper describes a technique of arthroscopically assisted fibular strut grafting for avascular necrosis of the humerus. This is a minimally invasive technique with low morbidity and an accurate way of placing the graft into the infarcted segment.Osteochondritis dissecans (OCD) of the knee is a subchondral bone abnormality that results in the separation of the articular cartilage and bone with subsequent progression to osteoarthritis. Unstable OCD lesions should undergo fixation to preserve the natural contour of the articular surface. Although several fixation procedures have been reported, the appropriate procedure remains unknown. Because the bony portion of the OCD lesion is usually thin, it is difficult to fix firmly with conventional methods. We began fixing OCD lesions with knotless PushLock anchors and sutures and have obtained satisfactory results. This report describes this fixation method that uses the PushLock suture anchor to treat unstable OCD lesions. This procedure also can be applied for traumatic osteochondral fractures.Meniscal tears treated with partial meniscectomies have been shown to significantly increase contract pressures within the tibiofemoral joint, and a complete focal meniscal deficiency may render the entirety of the meniscus functionally incompetent. Although various techniques of meniscal transplantation have been described, these techniques may require the excision of a considerable amount of healthy meniscal tissue. Furthermore, failures continue to frequently occur. Therefore, attempts to restoring normal knee kinematics and biomechanical forces are essential. Segmental meniscus allograft transplantations may offer the advantage of a robust repair by both maintaining knee biomechanics and biology while maximizing preservation of native meniscal tissue. Also, most meniscal deficiency involves only a portion of the meniscus, and thus we developed this technique to segmentally transplant only the deficient portion. The purpose of this Technical Note is to describe a technique of segmental medial meniscus allograft transplantation in a patient with focal medial meniscus deficiency.The presence of preoperative tunnel widening and/or malposition can pose technical challenges for revision anterior cruciate ligament reconstruction. This Technical Note describes the use of outside-in drilling to avoid the need for 2-stage reconstruction in the presence of tunnel widening or semi-anatomic tunnels.Double-bundle anterior cruciate ligament (ACL) reconstruction (DBACLR) is a reasonable transition from single-bundle ACL reconstruction to obtain better clinical outcomes, and most authors believe that it can only be performed through a medial portal. However, in our clinical practice, we have found that anatomic DBACLR can be performed easily and exactly through transtibial tunnels just by positioning the tibial tunnels appropriately. Thus, we would like to introduce this anatomic double-bundle transtibial ACL reconstruction technique, in which the most critical step is to create a shallow tibial tunnel for the anteromedial bundle with a proximal projection to the anatomic location of the corresponding femoral tunnel. We believe this Technical Note will give an interesting view of anatomic DBACLR.Acromioclavicular (AC) injuries are common, especially in the young and active population. AC joint dislocations account for 8% of all joint dislocations and are even more common in contact sports. These injuries are graded as type I through type VI on the basis of the Rockwood classification method. Types I and II are generally treated without surgery whereas types IV, V, and VI are best treated operatively. Type III dislocations remain controversial in terms of treatment, and many surgeons recommend nonoperative treatment first and operative treatment in case of continued symptoms such as pain, instability, or shoulder girdle dysfunction. The goal of operative treatment is to restore AC joint stability, which involves addressing both the coracoclavicular and coracoacromial ligaments to achieve a desirable patient outcome. The objective of this Technical Note is to describe our technique for management of a failed acromioclavicular stabilization, treated with a coracoclavicular and AC joint capsular reconstruction using tibialis anterior and semitendinosus allografts.Superior capsule reconstruction is a valuable intervention for some patients who present symptomatic irreparable posterosuperior rotator cuff tears. Superior capsule reconstruction techniques most commonly use either fascia lata autograft or dermal allograft. Both options have literature support but also present a few drawbacks such as donor site issues, potential allergic reactions, and high cost of the operation. The long head of biceps is a potential graft for rotator cuff tears and may be particularly useful in bridging the gap in irreparable massive rotator cuff tears, specifically as an alternative to more traditional superior capsular reconstruction. Long head of biceps transposition may offer unique and significant advantages over other techniques and can be an effective and valuable alternative in selected cases. The tendon's insertion into the glenoid is left intact, whereas laterally it is transferred to a more central humeral head position and sutured with anchors onto the footprint of the supraspinatus tendon acting as a superior static stabilizer of the shoulder joint. The purpose of this article is to propose a technical modification of superior capsular reconstruction using long head of the biceps tendon autograft.Surgical management of septic arthritis in young children is traditionally performed with open techniques, although arthroscopic approaches are commonly used in the knee and shoulder. Hip arthroscopy is technically demanding in small children and requires modification from traditional hip arthroscopy. The purpose of this study is to describe a safe technique to perform hip arthroscopy without traction in the pediatric hip and, secondarily, to report short-term results of a case series. Pediatric hip arthroscopy can be safely performed without traction on a radiolucent table and allows joint irrigation and debridement including drain placement through the use of 1 or 2 portals. Hip arthroscopy is a safe, valuable, minimally invasive technique in the treatment of children with septic arthritis of the hip.Humeral avulsion of the glenohumeral ligament (HAGL) is a rare cause of anterior shoulder instability. Recurrent instability and anterior shoulder pain could be caused by an unrepaired HAGL; therefore, making the diagnosis is crucial. Only a few articles describe arthroscopic HAGL repair. This uncommon technique uses lateral decubitus arthroscopy and standard Bankart instrumentation. Different methods used to facilitate visualization of the working space as well as anchor placements are described.Anterior cruciate ligament (ACL) rupture remains a debilitating orthopaedic pathology with a substantial economic and psychological burden on patients, especially athletes. The purpose of ACL reconstruction is to attain maximum joint stability and functionality, allowing patients to resume their previous level of activity. Several graft options and techniques are available for ACL reconstruction. The all-inside remnant-preservation technique is a minimally invasive approach aiming for improved proprioception, better graft integration, and increased graft strength via ACL augmentation by suture approximation with an optimal anatomic reconstruction. ACL augmentation is associated with a decreased risk of rerupture. Moreover, enhancement of knee proprioception via the presented technique allows an early return to activity by patients because weight bearing (with a brace) can be initiated as early as day 1 postoperatively. Patients can resume running activities by 2 months postoperatively and return to pivot sports by 3 months postoperatively. Despite this surgical procedure being technically demanding, it is associated with improved clinical outcomes and functional capacities. Patients are also found to better tolerate the postoperative rehabilitation protocol.The load-distributing function is most critical in meniscal function, and meniscal extrusion suggests failure of this function, leading to the progression of osteoarthritis. The arthroscopic centralization technique has been developed to reduce meniscal extrusion; however, existing arthroscopic techniques sometimes fail to reduce the most extruded region, especially in cases with a medial meniscus (MM) posterior root tear, in which the most extruded region is on the posterior border of the medial collateral ligament, which is very difficult to approach. This Technical Note describes an arthroscopic technique for extrusion of the MM in which a centralization technique using knotless anchors efficiently reduces the MM extrusion at the posteromedial part and consequently restores the MM function. This technique efficiently reduces MM extrusion and restores its function, thus preventing the progression of osteoarthritis.The surgical results of shoulder multidirectional instability are not satisfactory. To address the structural and biological factors that are related to the low success rate of surgical treatment, we developed a whole glenoid reconstruction technique, which includes mainly 270° glenoid bone grafting and capsule labrum reconstruction, and glenohumeral ligament reconstruction. Our clinical experience indicates that the application of this technique can result in optimal shoulder stability. We consider the introduction of this technique will shed light on the surgical treatment of shoulder multidirectional instability.The purpose of this technique paper is to outline a minimally invasive technique using dual suspensory fixation with adjustable-loop devices for reconstruction of the superficial medial collateral ligament. www.selleckchem.com/pharmacological_epigenetics.html The femoral fixation is performed through a limited approach at the anatomic origin of the medial collateral ligament, a socket is prepared, and the graft is docked using the adjustable-loop suspensory fixation. The tibial socket is prepared through a separate incision just distal to the pes anserine tendons and drilled medially to laterally perpendicular to the tibial shaft. The graft is tunneled and docked into the tibial tunnel using adjustable-loop cortical suspensory fixation on the far cortex. The knee is cycled through a full arc of motion and stressed in valgus to take initial creep out of the construct. The knee is placed in 30° of flexion and slight varus and final tension is applied to both the femoral and tibial side. With this technique, fixation can be completed with a minimally invasive incision and it allows the ability to tension the graft both on the femoral and tibial side to the desired level, providing a significant advantage over previously used interference screw techniques.
