Article Abstract
Purpose: To report short-term results and clinical outcomes of arthroscopic deepening trochleoplasty combined with medial patellofemoral ligament (MPFL) reconstruction utilizing standard arthroscopic instruments in patients of recurrent patellar dislocation and trochlear dysplasia.
Methods: This is a case series of 13 patients between the ages of 14 and 20 years who presented with recurrent patellar dislocation and severe trochlear dysplasia (Dejour grade D). They were treated surgically using an arthroscopic technique from February 2017 to January 2019 and were followed for 18 months. Patients were assessed preoperatively and postoperatively (at 6, 12, and 18 months) with clinical scores (Tegner Activity Score, Lysholm Knee Score, and Kujala Score).
Results: There were 69.2% females, and the mean age was 16.4 ± 2.0 years. There were statistically significant improvements in the mean Lysholm and Kujala scores when comparing pre-operative and post-operative scores at every follow-up landmark (p < 0.05). Comparing the preoperative and 18-month postoperative scores-the Lysholm score improved from 68.2 ± 10.3 to 98.7 ± 2.1 (p < 0.001), and the Kujala score improved from 50.3 ± 12.0 to 95.4 ± 4.8 (p < 0.001). Five patients were able to achieve premorbid Tegner activity levels at 12 months, with an additional 5 patients achieving the same premorbid Tegner activity at the 18-month mark. The remaining 3 patients were able to attain >90% of their activity level at 18 months' follow-up. No complications were observed during the follow-up period.
Conclusions: This proposed arthroscopic deepening trochleoplasty technique combined with MPFL reconstruction has demonstrated excellent and reproducible early clinical outcomes.
Level Of Evidence: IV.

Knee osteonecrosis (ON), often subclassified as spontaneous ON of the knee, secondary ON, and post-arthroscopic ON of the knee, is a common disorder often associated with suboptimal outcomes. Magnetic resonance imaging is the current gold standard for diagnosis, revealing bone marrow edema and subchondral fracture lines. Therapeutic methods range from conservative treatments, such as partial weight-bearing, pharmaceutical interventions, and physical therapy, to surgical procedures in cases of advanced joint collapse.

Background: Remplissage with Bankart repair (RMBR) is an arthroscopic procedure performed on <25% of Bankart lesions with off-track Hill-Sachs lesions (HSLs) that alters the insertion of the infraspinatus muscle into the humeral head. However, the effects of RMBR surgery on humeral head displacement due to changes in biomechanics and kinematics have not been fully elucidated.
Purpose: To evaluate how the biomechanical and kinematic effects of the post-RMBR glenohumeral joint influence humeral head displacement using the finite element analysis (FEA) method.

Purpose: Deepening trochleoplasty improves outcomes in patients with trochlear dysplasia. The aim of this systematic review was to present the outcomes after open thin-flap, open thick-flap and arthroscopic deepening trochleoplasty.
Methods: A systematic review was conducted using the PRISMA guidelines.

Purpose: This study aimed to update previously published clinical and radiographic outcomes of Dejour sulcus-deepening trochleoplasty and medial patellofemoral ligament reconstruction (MPFL-R) at mid-term follow-up and monitor trends in patient-reported outcome scores and satisfaction.
Methods: Using the same cohort of patients from our previously published short-term series of 2-year follow-up, an interval follow-up was performed on 67 patients (76 knees) with severe trochlear dysplasia and recurrent patellar instability who were prospectively enrolled and underwent Dejour sulcus-deepening trochleoplasty and MPFL-R combined with other patellar stabilization procedures. Patients with less than 2 years of follow-up were excluded.
