Entrapment of the sciatic nerve is considered a challenging problem for orthopaedic surgeons. Many surgical interventions (open or endoscopic) have been described as treatments. We describe an endoscopic technique for release of the piriformis tendon and sciatic nerve exploration by the lateral approach through an incision on the iliotibial band.

Hip dysplasia has been identified as one of the leading causes of osteoarthritis. However, hip arthroscopy alone, in the setting of hip dysplasia, remains controversial. In borderline hip dysplasia, with lateral center-edge angle (LCEA) between 18° and 25°, good outcomes have been reported with appropriate capsular and labral management. However, in severe hip dysplasia, with LCEA below 18°, there is an acetabular bony structural deficiency that must be addressed. Even with the potential benefit of hip arthroscopy in addressing intra-articular injuries related to the instability, it cannot be used for soft-tissue procedures...

Hills-Sachs lesions are bony lesions in the humeral head that occur as a result of an anterior shoulder dislocation. These lesions often happen in conjunction with tears of the labrum, and large, engaging lesions must be addressed in order to avoid recurrent instability. Moderate to large (≥3 mm deep) Hill-Sachs defects can be treated using arthroscopic remplissage to reduce the rotator cuff down into the lesion. We describe in this Technical Note and accompanying video an adaptation of the classic arthroscopic remplissage that uses a knotless double-pulley technique with 2 suture anchors, which increases the footprint of fixation, reduces the technical difficulty of the procedure, and minimizes the number of portals that need to be made...

Injuries to stabilizing elements on the medial side of the knee are one of the most common knee ailments. Because of the good healing capacity of these structures, acute injuries are typically treated conservatively. However, valgus laxity near full extension can persist in some patients. This laxity may be the source of instability due to medial joint space opening, which then requires surgical treatment. Various procedures have been described that aim to reproduce the anatomy of the medial collateral ligament (MCL) and the posterior oblique ligament (POL), which work together to stabilize the medial aspect of the knee...

Arthroscopic surgery has grown rapidly in recent decades. Despite accurately diagnosed clinical cases, the previous pain is retained in some patients after the operation, even though no visible chondral lesions are found during the procedure. A minimally invasive arthroscopic method of measuring articular cartilage electromechanical properties enables rapid and reliable intraoperative articular cartilage quality evaluation.

Medial meniscus posterior root tear (MMPRT) is now attracting increased attention as a risk factor for the development of osteoarthritis. However, the healing rate after root repair by the suture anchor technique or the pull-out technique is still low. Here we report on a technique of MMPRT repair using suture anchor combined with arthroscopic meniscal centralization and open wedge high tibial osteotomy (OWHTO). The purposes of this technique are (1) to distribute the meniscal hoop tension between the root repair site and the centralization site and (2) to reduce the load on medial meniscus by OWHTO...

Recently there has been renewed interest in primary repair of the anterior cruciate ligament (ACL). Repair of the acute proximal ruptured ACL can be achieved with the independent suture tape reinforcement ACL repair technique. The independent suture tape reinforcement technique reinforces the ligament as a secondary stabilizer, encouraging natural healing of the ligament by protecting it during the healing phase and supporting early mobilization. The purpose of this article is to describe, with video illustration, this ACL repair technique...

Posterior shoulder instability is an uncommon and challenging cause of shoulder pain and dysfunction. Surgical management has less reliable results and higher failure rates compared with techniques for anterior shoulder instability. The presence of generalized ligamentous laxity further complicates options for surgical management. If primary capsulolabral repair fails, controversy exists as to the optimal revision procedure. This technical description and video present an arthroscopic technique for reconstruction of the posterior glenohumeral capsule with an acellular dermal allograft to treat posterior instability in a patient with Ehlers-Danlos syndrome and a previously failed posterior capsular plication...

A technique for augmentation of the partial anterior cruciate ligament is presented. The patient is positioned supine with the knee flexed 90°. After addressing intra-articular injuries, the autologous semitendinosus tendon is harvested and measured in a doubled manner; after that, the tibial tunnel is performed in the outside-in direction, of the same diameter of the doubled graft. Both ends of the graft are sutured together, after inserting it through the loop of a suspension device, which is attached in its augmentation piece...

Anterior cruciate ligament (ACL) reconstruction with a bone-patellar tendon-bone autograft yields good clinical outcomes. Despite appropriate clinical outcomes, the most common complaint after reconstruction with a bone-patellar tendon-bone autograft is anterior knee pain at the donor graft sites. Synthetic bone grafts, such as beta-tricalcium phosphate (β-TCP), have been previously used to fill the bony defect in fractures as well as removal of bony tumors, and have shown positive utility in improving anterior knee pain after ACL reconstruction...

Elbow arthroscopy is an increasingly common procedure performed in orthopaedic surgery. However, because of the presence of several major neurovascular structures in close proximity to the operative portals, it can have potentially devastating complications. The largest series of elbow arthroscopies to date described a 2.5% rate of postoperative neurological injury. All of these injuries were transient nerve injuries resolved without intervention. A recent report of major nerve injuries after elbow arthroscopy demonstrated that these injuries are likely under-reported in literature...

The optimal management of recurrent anterior shoulder instability with significant glenoid bone loss continues to be a challenge. The high recurrence rates seen in arthroscopic Bankart repair in the presence of significant glenoid bone loss have led many surgeons to choose bony reconstructions to manage these injuries. The Latarjet procedure acts through the combination of 3 different mechanisms: the coracoid bone graft restores and extends the glenoid articular arc, the conjoint tendon acts as a dynamic sling on the inferior subscapularis and anteroinferior capsule when the arm is abducted and externally rotated, and the effect of repairing the capsule to the stump of the coracoacromial ligament...

Valgus extension overload syndrome (VEO) is the result of supraphysiologic stresses placed across the posterior elbow during pitching. Following failure of nonoperative measures, surgical options consist of arthroscopic or limited incision posteromedial decompression. Although technically challenging, arthroscopic treatment offers many advantages over open treatment, including improved joint visualization, decreased soft-tissue dissection, decreased postoperative pain, and quicker rehabilitation. Arthroscopic treatment of VEO consists of soft tissue and bony debridement, loose body removal, and osteophyte resection...

The treatment of massive rotator cuff tears (MRCT) is challenging. Insufficient tissue quality, size, and retraction of the cuff often lead to failures of repair. Different techniques like direct repair, partial repair, and graft applications have been developed, but results are not yet predictable. In this arthroscopic technique the objective is not to reconstruct the rotator cuff as a tissue layer but to restore the biomechanical function of the rotator cable with an autograft of the long head of the biceps tendon...

Acetabular bone cyst is usually associated with dysplastic secondary osteoarthritis of the hip joint. Acetabular reorientation osteotomy is one of the most common therapeutic options for treating patients with hip dysplasia. However, it may be too invasive for athletes and can also lead to some complications including intraoperative fracture and postoperative bone necrosis especially in patients with acetabular large bone cysts. Endoscopic shelf acetabuloplasty offers a less invasive option for athletic patients with dysplasia of severity greater than those indicated for isolated hip arthroscopy...

Despite the advent of sutureless technology, knot tying remains an important skill for any arthroscopist. When one is choosing which knot to tie, there are a variety of options, with each possessing its own inherent strengths and weaknesses. The West Point knot is a sliding-locking arthroscopic knot that is relatively easy to learn and has excellent knot security. This article details the appropriate manner in which to tie this knot.

Hip arthroscopy is useful in the treatment of several intra-articular pathologies, however, its use in high-energy hip and pelvis injuries raises concerns about fluid extravasion and stability of the pelvic ring. We present our arthroscopic surgical technique (initial access to the peripheral compartment) to remove intra-articular loose bodies and treat associated lesions, as well as our concerns with the technique, in case of a traumatic hip dislocation associated with a contralateral pelvic ring injury.

Proximal adductor injuries are relatively common groin injuries in athletes. Various tenotomy techniques have been described including open, partial, and percutaneous approaches. Current techniques help most athletes return to sport; however, many develop adductor weakness. Moreover, the procedures lack full visualization of the tendon and do not allow for return to athletes' preinjury level of play. We describe an endoscopic z-lengthening of the proximal adductor tendon with the potential to minimize complications associated with open procedures such as incisional pain and neurovascular injury while affording a more complete tenotomy than current percutaneous techniques...

The injuries of the posterolateral corner (PLC) of the knee often remain misdiagnosed. Because most structures in this anatomical region have low potential to heal, the posterolateral rotational instability results in a deterioration in patient quality of life, impaired biomechanics of the knee, and increased tension on other ligaments and the meniscus. Many open and a few arthroscopic techniques have been developed to repair or reconstruct the damaged structures of the PLC. Creating an additional midlateral arthroscopic portal on the lateral side of the knee was the key to developing the technique to recreate a static stabilizer against external rotational instability of the PLC by fixing the popliteus tendon as a native, vascularized material to the tibia...

Large post-traumatic osteochondral defects of the proximal tibia in young active patients can be challenging because total or partial arthroplasties are to be avoided. The use of a fresh osteochondral allograft including its meniscus is one of the few options to biologically treat these injuries. Although the use of a fresh allograft is not easily accessible in some places and carries considerable logistical limitations, it is an alternative that provides viable chondrocytes to the defect. The inclusion of the meniscus in the osteochondral graft improves the results but also makes the technique even more demanding...
