Objective: To evaluate the effects of successful TMJ treatment on relief of pain, improvement of mandibular movement and capsular width with clinical and ultrasonography (US) findings. In this study, TMJ changes were evaluated by clinical and US examination after US-guided single-puncture arthrocentesis, which represents a novel approach.
Methods: Clinical measurements were obtained before each procedure and at 1 day, 7 days, and 3 months thereafter. Capsular width was measured via the US at the 3-month follow-up.
Results: Significant improvements were evident at the short term of 3 months post-arthrocentesis with supportive treatment, including splint therapy and jaw exercises.
Conclusion: Arthrocentesis in conjunction with splint therapy and jaw exercises demonstrated significant clinical improvement at the short-term follow-up of 3 months. US imaging can be helpful for follow-up evaluation of the pre- and post-treatment capsule width. Longer follow-up studies are necessary to validate the effectiveness of this treatment protocol.

Clinical and Radiological Outcomes After Lateral Meniscal Allograft Transplantation Through a Medial Arthrotomy: A Minimum 4-Year Follow-up.
Orthop J Sports Med
January 2025
Department of Orthopaedic Surgery, Case Western Reserve University, Cleveland, Ohio, USA.
Background: Previous studies have demonstrated that lateral meniscal allograft transplantation (MAT) through medial arthrotomy showed less extrusion than that of the lateral arthrotomy. However, there is a paucity of literature reporting clinical and radiological outcomes after lateral MAT through the medial arthrotomy.
Hypothesis: Lateral MAT through a medial arthrotomy would show significantly improved clinical scores and minimal joint space narrowing compared with preoperative status.

Introduction: Glenoid rim fractures with Bankart lesions are called bony Bankart lesions and are associated with persistent glenohumeral joint instability. Acute bony Bankart lesions can be treated by various arthroscopic techniques. Here, we present a technique of arthroscopic bony Bankart repair using suture-assisted reduction and screw fixation.

This research uses mathematical modelling to evaluate the influence of the ligament of Wieger on the crystalline lens shape at rest, and during accommodation. An axisymmetric model of the anterior segment, including the ligament of Wieger, was created using the finite element method. Different conditions including variations of stiffness and positions of the ligament, with and without the ligament, were tested to see how they affected lens curvature and optical power.
