Appreciation of persistent anterolateral rotatory instability and graft failure after anterior cruciate ligament (ACL) reconstruction procedures has led surgeons to adopt the addition of lateral extra-articular tenodesis (LET) in both the revision and primary setting. Multiple techniques have been shown to eliminate anterolateral rotatory instability and reduce forces on the ACL graft, which has translated to lower re-rupture rates and improved patient outcomes. The risk of ACL/LET tunnel convergence can potentially compromise the fixation of one or both graft reconstructions.

The renewed interest in ACL repair over the last two decades stems from advances in modern arthroscopic techniques and clinical studies that have provided evidence that the ACL can reliably heal, and patients can return to sport at a comparable rate to ACL reconstruction patients. The ability to maintain and utilize native ACL tissue, with proprioceptive capabilities, and the smaller drill tunnels needed to repair an ACL leads to an overall less invasive procedure and improved early rehabilitation. Additionally, repair avoids a variety of comorbidities associated with autograft harvest.

Background: Shoulder pain following intramuscular administration of vaccine is common. However, a small number of patients experience prolonged pain and dysfunction atypical to normal transient postvaccination shoulder pain. Shoulder Injury Related to Vaccine Administration (SIRVA) remains incompletely understood, whether a robust immune response to vaccine antigen or inappropriate injection technique with needle placement in synovial or bursal tissue, or some combination of the two.

Treatment of full-thickness rotator cuff repairs vary in surgical technique depending on many factors including tear geometry, delamination of soft tissue, tissue quality, and rotator cuff retraction. The described technique presents a reproducible method of addressing tear patterns where the tear may be larger laterally, but the medial footprint exposure is small. This can be addressed with a single medial anchor combined with a knotless lateral-row technique to provide compression for small tears or two medial row anchors for moderate to large tears.

Purpose: To evaluate the radiographic effect of quadriceps tendon harvest on patellar height and to determine whether closure of a quadriceps graft harvest defect resulted in a significant change in patellar height compared to nonclosure.
Methods: We conducted a retrospective review of prospectively enrolled patients. The institutional database was queried and all patients who underwent quadriceps autograft anterior cruciate ligament reconstruction between 2015 and March 2020 were included.

The medial collateral ligament (MCL) is a major contributor to knee joint stability and is the most common ligament involved in knee injuries. When conservative management for high-grade MCL injuries fails, operative treatment is indicated. Various reconstruction techniques are described in the literature.

Osteochondral allograft transplantation is a viable option for large chondral defects >2 cm squared, as well as in a revision setting after failure of a previous surface chondral restoration procedure. Osteochondral lesions involving the posterior aspect of the femoral condyle, however, are less common and easily underappreciated. Treatment of posterior osteochondral lesions is more technically demanding because they cannot be adequately addressed through standard arthroscopic approaches or an anterior arthrotomy.

Revision surgery, psychiatric history, preoperative chronic knee pain, and subsequent knee injury are associated with suboptimal recovery patterns. Sophisticated growth models can analyze patient recovery trajectories.

Treatment options for massive irreparable rotator cuff tears continue to evolve. Recently bursal acromial reconstruction (BAR) has been described as an additional option to reduce pain and improve comfort. As originally described, an acellular dermal allograft is secured to the underside of the acromion as an interposition graft.

The middle glenohumeral ligament (MGHL) is well recognized as a primary stabilizer of the shoulder. Its role in shoulder pathologies such as adhesive capsulitis, subscapularis tendon tear, and glenohumeral arthritis is less understood. Biomechanically, the MGHL plays an important role in range of motion, specifically involving normal and pathologic external rotation in less than 45° of abduction.

The range of diagnostic and therapeutic applications of needle arthroscopy (NA) continue to expand due to advances in image quality and resolution. Minimally invasive techniques can be augmented by the smaller camera size and reduced fluid use made possible by NA. Small-bore arthroscopy presents opportunities for use in smaller joints, such as the elbow, where applications of standard arthroscopic equipment may be limited by small anatomic spaces and fluid extravasation.

Rotator cuff tears involving the musculotendinous junction with a significant amount of tendon still attached to the footprint laterally represent a challenging scenario for shoulder arthroscopists. Because of these challenges, adjunctive techniques to bridge tissue gaps may be required, and biologic augmentation may be considered to improve the healing environment. The following technique presents a stepwise approach to accomplishing the dual goals of a stable anatomic repair and biologic augmentation of this difficult pattern of rotator cuff pathology.

Needle arthroscopy may provide several potential advantages over standard arthroscopy. The smaller camera size and weight allows for a minimally invasive and percutaneous approach with decreased fluid use. As resolution and image quality improve, the potential to expand clinical use for therapeutic applications becomes possible.

As resolution and image quality improve, several potential advantages make needle arthroscopy (NA) appealing for broader therapeutic applications in the operating room. Smaller camera size and weight allow for a minimally invasive approach with smaller incisions than standard arthroscopy and decreased use of arthroscopic fluid. Differences in the technology, such as a 0° optic and less rigid instrumentation, necessitate a modified technique to accommodate thorough diagnostic arthroscopy as well as modified approaches to therapeutic procedures.

Treatment of full-thickness rotator cuff tears vary in surgical technique dependent on the amount of retraction of the rotator cuff and/or delamination of the soft tissue. The described technique addresses both of those concerns. We present a modification of the SpeedBridge technique used to address retracted or delaminated repairs and effectively expand the indications for use of the double-row knotless technique.

Introduction: Pre-existing conditions and surgical interventions, such as those associated with Osgood-Schlatter disease, can lead to atypical patellar tendon ruptures. These cases can present irregularly and be challenging to diagnose. Patellar tendon rupture from the tibial tubercle insertion region is a rare, and currently undocumented condition, requiring surgical intervention to restore knee joint functionality for daily activities.

Introduction: Low bone density complicates the surgical management of fractures. Screw stripping in osteoporotic bone leads to decreased fixation strength and weakening of the fixation construct. If low density could be detected during drilling, augmentation may be performed to prevent screw stripping.

Posterolateral corner avulsion fractures are a rare variant of ligamentous knee injury primarily described in the skeletally immature population. Injury is often related to a direct varus moment placed on the knee during sporting activities. Various treatment strategies have been discussed ranging from nonoperative management, to excision of the bony fragment, to primary repair with screws or suture.

All-inside anterior cruciate ligament reconstruction has recently gained popularity, in part because of its bone-sparing socket preparation and reported lower pain levels after surgery. However, because this technique uses suture loops and cortical suspension buttons for graft fixation, it has mostly been limited to looped graft constructs (e.g.

Subscapularis tendon tears present a technical challenge because both diagnosis and arthroscopic treatment can be difficult. One difficulty is the limited visualization and working space of the anterior shoulder. Although most tears of the subscapularis are partial- or full-thickness tears of the upper third of the tendon, occasionally, larger or more retracted tears are encountered.
