Anterior cruciate ligament reconstruction (ACLR) using suture tape augmentation to internally brace is a relatively new technique. The primary goal of this study was to prospectively collect patient-reported outcomes (PROs) and surgical history from patients who underwent primary ACLR with internal bracing to determine if internal bracing resulted in a low graft failure rate while maintaining acceptable PROs. A total of 252 patients with a mean age of 23.

Purpose: The purpose of this study was to assess patellar tendon (PT) and quadriceps tendon (QT) thickness on preoperative magnetic resonance imaging (MRI), in both the sagittal and axial planes, at multiple points along each tendon, and to correlate these findings to anthropometric patient data before anterior cruciate ligament (ACL) surgery.

Methods: Patients who underwent PT or QT autograft ACL reconstruction between 2020 and 2022 and who had preoperative MRIs with adequate visualization of the proximal QT and distal PT were retrospectively identified Patient demographics were recorded (age, height, weight, sex, injury side). Preoperative MRI measurements were performed by 3 independent examiners using standardized protocol.

Arthroscopic posterior cruciate ligament (PCL) reconstruction is a technically demanding procedure, particularly with respect to tibial footprint debridement and tibial tunnel placement, where iatrogenic damage to anatomic structures is a well reported complication and incorrect tunnel placement can have functional implications. Preparation of the tibial component often involves switching between 30° and 70° arthroscopes and frequent portal swapping and reorientation, which can be inefficient and time-consuming. As the technology and picture resolution of needle arthroscopy has improved, its clinical application has widened.

There has been a shift in US health care to a system that emphasizes value. Patient-reported outcomes have become a critical component of that valuation. A 5-year quality improvement project at the community private practice level was undertaken to assess the authors' delivery of care and practice processes for shoulder surgery as compared with established standards.

Case: Medial patellar instability (MPI) is a known sequela of previous lateral retinacular release. Literature on surgical intervention is scarce. We present a case of a 35-year-old woman with hypermobility type Ehlers-Danlos syndrome, with bilateral iatrogenic MPI (IMPI) and lateral patellar instability.

Coracohumeral ligament pathology arises from acute trauma, capsular thickening, or congenital connective tissue disorders within the glenohumeral joint. Recent studies have highlighted the significance of this pathology in multidirectional shoulder instability because insufficiency of the rotator interval has become increasingly recognized and attributed to failed shoulder stabilization procedures. The diagnosis and subsequent treatment of coracohumeral ligament pathology can be challenging, however, because patients usually present with a history of failed surgical stabilization and persistent laxity.

Electrodiagnostic studies (EDX) serve a prominent role in the diagnostic workup of cubital tunnel syndrome (CBTS), but their reported sensitivity varies widely. The goals of our study were to determine the sensitivity of EDX in a cohort of patients who responded well to surgical cubital tunnel release (CBTR), and whether the implementation of the Association of Neuromuscular and Electrodiagnostic Medicine (AANEM) criteria improves the sensitivity. We identified 118 elbows with clinical CBTS who had preoperative EDX and underwent CBTR.

Although concussions are common, they are complex, variable, and not entirely understood in terms of pathophysiology and treatment. The incidence of concussion is expected to continue to rise with the increased participation of youth in sports and improved awareness. The role of orthopedic surgeons in concussion management is murky.

Hypothesis/background: Iatrogenic pneumothorax is a rare but serious complication of open reduction and internal fixation (ORIF) of clavicular fractures. Many institutions use postoperative chest radiographs to evaluate for this complication despite a lack of data to support this routine practice. Due to concerns of radiation exposure and health care costs, this practice may not be necessary.

There is a known bleeding risk with administration of the antiplatelet drug clopidogrel, but in certain patients the likelihood of thrombosis is too high to cease its administration perioperatively. The risks of performing total joint arthroplasty in this population are unknown. An inpatient pharmacy database query identified seven patients who underwent eight hip or knee arthroplasties from 2007 to 2009 without perioperative interruption in clopidogrel administration.

Case: We present a case of a seventy-one-year-old woman with recurrent anterior dislocation of the shoulder in the setting of an irreparable rotator cuff tear and degenerative joint disease.

Conclusion: In an elderly patient with recurrent anterior shoulder dislocation and an irreparable rotator cuff tear, reverse total shoulder arthroplasty (RTSA) is a viable surgical intervention. In the case presented here, RTSA resulted in the patient exhibiting increased range of motion, reporting an improved quality of life, and having no additional dislocation events as of the two-year follow-up.

Neurovascular injury during total hip arthroplasty (THA) may result in considerable morbidity or mortality. The most common cause of intraoperative neurovascular injury during THA is retractor compression. Our aims were to: 1) determine proximity of common acetabular retractor positions during THA to adjacent neurovascular structures; and 2) determine effect of patient gender on these measurements.
