Purpose: The purpose of this preliminary study was to evaluate intraarticular soft tissues of the temporomandibular joint (TMJ) using intraoperative arthroscopy during open reduction and internal fixation (ORIF) of condylar head fractures (CHF).
Materials And Methods: 26 patients (29 joints) were diagnosed in period of 5 years (2011-2015) with CHF, 5 patients had concomitant mandibular fracture. Fractures were diagnosed on basis of conventional orthopantomogram (OPG) and computed tomography (CT).
Results: Intraoperative arthroscopy revealed hyperemia and hypervascularity in all 29 joints, anterior disc dislocation in 26 joints, cartilage erosion in 21 joints and hemorrhagic clots were present in 10 joints. Major hemarthrosis or tear of the posterior band, as often described in MRI, could not be shown in our patients. Data from the study further the understanding of intraarticular pathology of the TMJ after acute trauma in a group with CHF.
Conclusion: Intraoperative arthroscopy is useful for direct evaluation and accurate diagnosis of the extent of soft tissue damage to TMJ in CHF. Larger and more long-term studies including comparison to MRI findings should be helpful to refine the treatment and postoperative management of patients after CHF.

Tranexamic acid use in rotator cuff repair: A systematic review of perioperative outcomes.
J Orthop
July 2025
Department of Orthopaedic Surgery, St. Luke's University Health Network, Bethlehem, PA, USA.
Background: Tranexamic acid (TXA) use has become the gold standard in total joint arthroplasty to limit intraoperative blood loss and transfusion rates. More recently, the indications for TXA have expanded to knee and shoulder arthroscopy with promising early results. However, the effectiveness of TXA during arthroscopic rotator cuff repair (RCR) is unclear.

Purpose: To determine the effectiveness of administering intravenous (IV) tranexamic acid (TXA) on altering visual field clarity (VFC) during arthroscopic hip preservation surgery for patients with femoroacetabular impingement syndrome (FAIS).
Methods: This randomized, double-blind, parallel-design trial was conducted over a seven-month period between October 2023 and May 2024 at a single tertiary musculoskeletal hospital. Inclusion criteria included consecutive patients that were diagnosed with FAIS through clinical history, physical exam and advanced imaging and indicated for hip arthroscopy after having failed conservative management.

Electronic address:
Purpose: To review patients with recurrent patellar dislocation surgically treated with robot-assisted medial patellofemoral ligament (MPFL) reconstruction compared with patients who underwent surgery using the traditional freehand technique.
Methods: A retrospective cohort study was performed to identify patients who underwent MPFL reconstruction from January 2020 to December 2023 in our hospital. The inclusion criteria were: patients aged from 15 to 50 years; patellar dislocation occurred two or more times; a Merchant view or computed tomography (CT) scan indicating patellofemoral joint malalignment, external patellar inclination, or lateral patellar dislocation; underwent MPFL reconstruction via robot-assisted or traditional freehand technique; complete medical records and imaging data before and after surgery; a minimum of 1 year of postoperative follow-up.
Comparison of Interportal and Periportal Capsulotomies and Axial Distraction Resistance During Hip Arthroscopy: An In Vivo Propensity-Matched Cohort Study.

Department of Orthopaedics, University of Utah, Salt Lake City, Utah, USA.
Background: Intraoperative hip capsule management is increasingly recognized as an important component of hip arthroscopy for the prevention of capsular-related instability. The periportal capsulotomy, relative to the interportal capsulotomy, has been proposed as a minimally invasive technique for decreasing postarthroscopy hip instability; however, the biomechanical effects of this technique are not well established.
Purpose/hypothesis: This study aimed to provide a biomechanical characterization of interportal and periportal capsulotomies, helping inform surgeon choice of capsulotomy type and repair, potentially guiding clinical practice in hip arthroscopy.
Prevention and Management of Postoperative Infection After Anterior Cruciate Ligament Reconstruction: A Narrative Review.

: Postoperative infection following anterior cruciate ligament reconstruction (ACLR) is a rare yet severe complication that can compromise patient outcomes, leading to prolonged recovery, graft failure, and knee dysfunction. Although infection rates are reported to be less than 2%, it remains essential to implement strategies to reduce infection risk and improve surgical outcomes. : This review explores current evidence on the prevention of infections in ACLR, emphasizing the importance of timely antibiotic prophylaxis and vancomycin presoaking of grafts, which has been associated with a substantial reduction in infection rates.
