The mechanical function of the patellofemoral joint is an integral part of knee biomechanics, and remains a primary source of important clinical entities. Force transmission is the most central issue and can be described by relevant anatomical and biomechanical principles. The brief review highlights these issues focusing on recent applications to total knee arthroplasty.

Background: In the knee joints of patients with recurrent patellar dislocation (RPD), an increased relative tibial external rotation (rTER) is often observed. However, the changes in this parameter pre- and postoperatively remain unclear.
Purpose: The purpose of this study was to reveal preoperative and postoperative changes in rTER in patients with RPD.

Objective: Patellofemoral pain syndrome (PFPS) is a common knee issue, and hip joint function significantly affects knee health. Gluteus activation exercises are a promising treatment for PFPS. This study aims to investigate the impact of gluteal muscle activation exercises on the muscle involvement and movement patterns of young male patients with PFPS.

This editorial draws an analogy between the literary genre of the 'whodunit' and the complexities of patellofemoral pain (PFP). Traditionally, PFP management has centered on biomechanical factors such as hip muscle weakness, foot pronation, and patellar tracking issues. However, long-term outcomes often remain unsatisfactory, highlighting the need for alternative strategies.

Purpose The infrapatellar fat pad (IFP) has the lowest pain threshold among all knee joint components and causes anterior knee pain after knee arthroplasty. It has been reported that selective muscle atrophy of the vastus medialis (VM) and fibrosis of the IFP may develop following knee joint surgery. Ultrasound enables visualization of IFP deformation (A1) from within the joint to the proximal area in response to muscle contraction, and this may be helpful in developing preventive and therapeutic strategies for IFP fibrosis.

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.
