A growing number of knee cartilage repair studies continue to be published, employing both traditional and also novel and emerging surgical methods. Marrow stimulation, osteochondral transplantation, and autologous chondrocyte implantation via varied surgical techniques and delivery methods exist, as well as isolated, or concomitant, realignment procedures. However, while some value exists in small clinical cohorts (prospective and retrospective), we still lack high-quality comparative studies that better direct us toward the ideal cartilage repair treatment, specific to each individual patient situation including chondral defect (size, location, shape, etc.), the local environment (early degenerative knee changes, concomitant pathology), the surrounding environment (including individual physical conditioning and lower-limb alignment), and of course the patient's tolerance to the pathology and individual physical demands. How do we sort this out? High-quality, and hopefully prospective and randomized, clinical trials are required.Tranexamic acid (TXA) has been administrated in many orthopaedic surgical procedures to decrease perioperative and postsurgical bleeding. Relatively scant literature exists regarding the effect of TXA in patients after anterior cruciate ligament reconstruction. Currently, most evidence shows that within about 1 month after anterior cruciate ligament reconstruction, TXA can effectively reduce postoperative joint swelling and pain, as well as the aspiration rate. However, there are still controversies regarding the optimal dosage, timing, and route of administration of TXA in these patients. In addition, the potential chondrotoxic effect of TXA needs to be further clarified with longer clinical follow-up.Isolated tibial posterior cruciate ligament avulsion fractures, although rare, are becoming increasingly common in regions of the world with frequent 2-wheel motor vehicle accidents. Arthroscopic-assisted suture fixation has become a popular fixation method for these injuries. Suspensory metal button fixation of tibial posterior cruciate ligament avulsion fractures, although commonly used for other applications, has until recently been limited to isolated reports of a few patients.Virtual reality (VR) simulation has enormous potential utility in technically demanding manual activities. Hip arthroscopy is a perfect example of a challenging surgical technique with an extensive learning curve. The literature has recently consistently demonstrated that both career and annual maintenance case volume significantly influences patient-reported outcomes and risk of revision surgery and complications. Current residency and fellowship programs do not sufficiently prepare trainees to meet or exceed experience thresholds, so augmentation of training is necessary. A significant strength of VR simulation includes its ability to practice without limits. Unfortunately, hip models are limited to simple tasks, without full surgery models yet available simulating routine arthroscopic hip preservation procedures like labral repair, cam and pincer correction, capsular repair. Advanced techniques like labral reconstruction or augmentation, protrusio acetabulae, extensive cam morphology, revision surgery, peritrochanteric space endoscopy, and deep gluteal space endoscopy are not yet available for simulation. VR simulation can probably achieve competence for most, if not all, surgeons; possibly achieve proficiency; and unlikely to achieve mastery. The use of machine learning and artificial intelligence can process vast quantities of photo and video data to generate high-fidelity, lifelike surgical simulation. The near future will incorporate and assimilate these technologies cost-effectively for training programs and surgeons. selleck screening library Our patients will benefit.In patients with femoroacetabular impingement (FAI), hip joint pathology often leads to an alteration of gait as well as core and pelvic muscular imbalance. Flexor, abductor, adductor, and hamstring tightness and pain are common patient-reported complaints at the time of evaluation for FAI and potential hip arthroscopy. Surgical interventions have been developed to target all of these potential issues, but the question remains whether these concurrent procedures are necessary, or whether postoperative rehabilitation and other conservative measures may better treat associated conditions. We recommend that iliotibial band release is not indicated for patients with nonsnapping extra-articular lateral hip pain and should be reserved for frank, external snapping hip. Patients with lateral hip pain that prevents them from lying on their side at night are candidates for endoscopic trochanteric bursectomy through a minimal longitudinal ITB incision. Patients with evidence of gluteus medius pathology including positive Trendelenburg test, Trendelenburg gait, or pain with resisted hip abduction are treated with either bioinductive patch gluteus medius tendon augmentation or endoscopic or open abductor repair. The challenge is determining which of these associated conditions are compensatory (i.e., will improve after the underlying hip pathology is addressed during FAI surgery), and which are pathologic (i.e., must separately be addressed at the time of surgery).The management of the hip capsule has been a recent area of controversy in hip arthroscopy. Over the past 5 years, there has been mounting biomechanical and clinical evidence that complete capsular closure is an important step to achieve the best and most durable outcome from hip arthroscopy. Numerous studies in the laboratory have shown that repairing the capsulotomy during simulated hip arthroscopy establishes normal hip biomechanics. Multiple studies have also reported improved clinical outcomes and less conversion to total hip arthroplasty in patients undergoing capsular repair. We have published that patients improve after revision hip arthroscopy for repair of capsular defects. I think it is safe to say that complete capsular closure after hip arthroscopy is becoming the standard of care in our field.Ligamentum teres (LT) tears are correlated with hip instability, and biomechanical research suggests there is a stabilizing function of the intact native LT. With regard to LT reconstruction, currently, there are imaging studies demonstrating that the ligament goes on to heal and properly function. There are also no long-term clinical studies on the success rates of LT reconstruction. The clinical studies that have been done are done with a fairly high number of concomitant procedures, which makes it difficult to discern whether improvement can be attributed to the LT reconstruction. A recent review shows that after LT reconstruction, these very difficult patients can respond favorably to surgery two-thirds of the time. However, in the remaining one-third of patients, an additional surgery was required. In my own practice, patients with instability patterns on examination who have failed primary arthroscopy and have any degree of even minor bony dysplasia with signs of ligamentous laxity and LT tear are a population that I personally would recommend a periacetabular osteotomy to optimize bony stability.
