This experimental cadaver study assessed computer navigation for the arthroscopic measurement of full-thickness cartilage defects in the knee joint. Cartilage defects were measured during arthroscopy using three cartilage defect-managing modules to compare fixed (invasive) and noninvasive rigid-body fixations. The comparison of all three systems tested revealed a difference between the noninvasive and the fixed rigid-body fixation, with a mean value of 0.07 mm for the width, 0.15 mm for the height, and 0.17 mm for the surface area of the cartilage defect (P > .05). Every point of the cartilage defect was attainable with the pointer tip. The force applied to the instrument during the defect palpation to keep the leg stable during the navigation process was acceptable. In conclusion, the cartilage defect-managing module allows the precise measurement of full-thickness cartilage defects in the knee joint during arthroscopy and that the module can be used with noninvasive rigid-body fixation.

Background: The prevalence of labral tears in asymptomatic active adults has been reported, but the prevalence of labral tears and other incidental hip lesions in the asymptomatic active pediatric population remains unclear. The purpose of this study was to determine the prevalence of hip abnormalities detected on 3T MRI in an active pediatric population with no hip symptoms and to compare with hip abnormalities found in children and adolescents who underwent an MRI for a hip-related condition.
Methods: After IRB approval, pediatric patients self-reporting as athletes and presenting with isolated, acute-onset knee pain requiring knee MRI were prospectively recruited to undergo 3T MRI of their asymptomatic contralateral hip (ASx).

Introduction: The nasoseptal flap (NSF) has become a widely favoured choice for reconstructing skull base defects following the endoscopic endonasal approach (EEA). However, the exposed septal cartilage and bone at the donor site often require an extended duration for secondary healing. This study investigated whether the free middle turbinate (MT) mucosa grafting at the septal donor site could mitigate post-operative nasal morbidity.

Background: Fresh osteochondral allograft (OCA) transplantation is an established treatment option for patients with chondral or osteochondral lesions of the knee. Predictably positive outcomes are seen in situations of focal or isolated cartilage defects. However, OCA transplantation may also be performed in more complex joint salvage situations in young patients.

Background Deep learning (DL) methods can improve accelerated MRI but require validation against an independent reference standard to ensure robustness and accuracy. Purpose To validate the diagnostic performance of twofold-simultaneous-multislice (SMSx2) twofold-parallel-imaging (PIx2)-accelerated DL superresolution MRI in the knee against conventional SMSx2-PIx2-accelerated MRI using arthroscopy as the reference standard. Materials and Methods Adults with painful knee conditions were prospectively enrolled from December 2021 to October 2022.

Reverse Hill-Sachs lesions (RHSL) are common complications associated with posterior shoulder dislocations and represent a significant challenge for preserving joint stability and function. If untreated, these compression fractures of the anteromedial humeral head can compromise the integrity of the joint, predisposing patients to recurrent instability and arthropathy. While various treatment modalities exist, achieving an anatomic reduction of the defect while preserving the articular cartilage remains a desirable outcome, particularly in acute settings.
