There is a vast amount of conflicting literature evaluating the anatomic, biomechanical, and clinical outcomes of combined anterior cruciate ligament (ACL) and anterolateral complex injury. This has become-and remains-one of the most controversial topics in the ACL-deficient knee literature, thus requiring further inquiry with clear and systematic approaches to biomechanical analysis, indications, graft selection, surgical technique, and clinical outcome evaluation. The considerable variety of procedures to address anterolateral rotatory instability in the setting of ACL deficiency described in the literature strongly suggests the lack of a reliable and reproducible technique. Anterolateral complex reconstruction may provide protection to the ACL-reconstructed knee without detrimental overconstraint. The negative consequences of neglected posterolateral corner injury (PLC) have led to numerous advancements in the understanding and treatment of these injuries. As anatomic, biomechanical, and clinical knowledge of PLC injury continues to progress, finding the balance between re-creating native anatomy and safely performing PLC reconstruction continues to provide challenges to surgeons managing this complex constellation of injuries. Hip pain in patients with systemic inflammatory diseases may arise from synovitis, cartilage degeneration or bony abnormalities like femoroacetabular impingement or acetabular dysplasia. With advances in early diagnosis and medical management of the autoimmune response, these often-young patients may benefit from correction of underlying bony abnormalities like femoroacetabular impingement. Short-term improvement in patients' pain and function can be achieved with hip arthroscopic treatment. However, the long-term efficacy of hip arthroscopy in systemic inflammatory disease needs further research. Careful selection of patients with nondysplastic hips without significant cartilage degradation, correction of underlying bony abnormalities, collaboration with rheumatologist, and use of evidence-based perioperative management of anti-rheumatic drugs are keys to success. Capsular management during hip arthroscopy can influence the outcome of the operation for better or for worse. Capsulectomy and unrepaired capsulotomy can lead to residual hip instability. Capsular repair has been associated with improved outcomes after surgery compared with unrepaired capsulotomies. Repair or plication of the capsule can be facilitated by effective capsular elevation during central- and peripheral-compartment work. If capsular deficiency is present in a symptomatic patient with continued instability, capsular reconstruction is a viable option. The question of capsule closure or no closure after hip arthroscopy remains controversial as we try to decipher best practice and which patients should and should not have a repair. https://www.selleckchem.com/products/vb124.html Closure seems of particular importance in younger patients and with larger capsulotomies. In my practice, I routinely repair the capsule after hip arthroscopy, except in patients with significant stiffness. Capsule repair may not be vital in some patients, as a smaller capsulotomy could sometimes heal on its own, but my patients and I certainly do not want to learn the hard way. The use of regenerative technologies including mesenchymal stromal cells, also known as connective tissue progenitors (CTPs), has gained tremendous popularity as a primary and adjuvant treatment for many musculoskeletal conditions. The concentration of bone marrow-derived CTPs delivered to the site of injury has been directly correlated to the therapeutic effect in the setting of rotator cuff repair and the healing of long-bone fractures. In addition, there has been some limited in vitro and in vivo evidence to suggest that the delivery of bone marrow-derived CTPs may improve cartilage regeneration. Bone marrow aspirate concentrate harvested from the body of the ilium during hip arthroscopy yields a CTP concentration that is commensurate with other conventional donor sites and appears to be safe. However, the clinical benefit and financial cost associated with the delivery of bone marrow aspirate concentrate to the hip joint at the time of acetabular labral repair remains unclear at best and should be approached with caution. Published by Elsevier Inc.Proximal hamstring tendon injuries are uncommon injuries, and there are few high-quality studies of surgical procedures in the literature. Increasing standardization of outcome measures with the use of validated, injury-specific, patient-reported outcome measures will improve research in this area. This will allow better assessment of novel surgical techniques. The learning curve for hip arthroscopy is steep. This progress represented a combination of both increased technical skill and, importantly, development of more refined surgical indications. In the end, safety and efficiency are aspects of a well performed operation, and the ultimate aspect is long-term patient outcome. Elbow arthroscopy is a procedure that is of great potential use and yet also of grave potential risks. To balance the risk-versus-reward consideration, one must be aware of the potential complications associated with this procedure, weigh them against the potential advantages, and understand one's own skills and familiarity with the procedure. There is no doubt that elbow arthroscopy has changed and even revolutionized our management of pathology about the elbow; however, one must bear in mind that this comes at a risk of complications that cannot be reduced to zero. Repetitive throwing in the adolescent athlete often leads to long-term problems. Strict pitch counts and limitation of pitches (e.g., curve balls) that place extreme stress on the immature elbow must be monitored closely. And until our outcomes for osteochondritis dissecans of the capitellum in adolescent baseball players improve, it may be wise to counsel those pitchers and catchers who are symptomatic to consider switching to another position or sport. More than 100 surgical techniques have been described for the reconstruction of the coracoclavicular ligament complex. None of the techniques appears superior, but double-button fixation for acute high-grade acromioclavicular dislocations has become an attractive option. The clinical outcomes are good to excellent, and the return to physical activity and sport is above 90%. However, complications such as loss of reduction and tunnel widening have been described and can reach up to 80%. The load to failure of the native coracoclavicular complex is more than 600 N, and any surgical technique must surpass this figure. Single-button and loop techniques do not always sufficiently stabilize the acromioclavicular joint. Even double- and triple-button techniques may not restore vertical and horizontal stability of the acromioclavicular joint to its native normal state. Double-button technique restores both scapula and clavicular rotation closest to the native state, but still has lower stiffness and results in higher superior-inferior translation, which could cause ongoing vertical instability.
