Morphologic Variation of Patellofemoral Joint in Nepalese Patients with Recurrent Patellar Instability: A Case-Control Study

Nepal Orthopedic Association Journal | 2026 | Pranodan Poudel

Background: Recurrent patellar instability (RPI) is strongly influenced by osseous morphology of the patellofemoral joint, yet population-specific data from South Asia remain scarce. This study evaluated magnetic resonance imaging (MRI) parameters of trochlear and patellar geometry in Nepalese patients with RPI compared with matched controls. Methods: In this hospital-based cas...

Impact of Femoral and Tibial Torsion on Patellofemoral Loading in Individuals With Patellofemoral Instability

Journal of Orthopaedic Research | 2025 | Bernhard Guggenberger, Willi Koller, Andreas Habersack, Tanja Kraus

ABSTRACTPatellofemoral stability is affected by several morphological factors including torsional alignment. To elucidate the impact of factors responsible for the stability of the patellofemoral joint, biomechanical research utilizes the analysis of joint contact forces. At present, there is a paucity of modeling‐based research examining the influence of lower limb torsion on...

Medial Patellofemoral Ligament Reconstruction Using Suture Tape for Patellofemoral Joint Instability

Orthopaedic Surgery | 2021 | Jun‐cai Xu, Bo‐xuan Zhang, Yan‐feng Jia, Xiao‐feng Wang

ObjectiveTo describe a surgical technique using suture tape for reconstruction of the medial patellofemoral ligament (MPFL). This technique restores the stability of the reconstructed ligament and has excellent postoperative outcomes.MethodThis is a retrospective analysis. From January 2016 to June 2018, 17 patients underwent MPFL reconstruction using high‐strength suture (Fibe...

Arthroscopic assessment of patellofemoral tracking predicts patellar instability

Orthopaedic Journal of Sports Medicine | 2017 | Ritwik Kejriwal, Peter Annear

Objectives: Surgical management of patellar instability includes proximal realignment procedure such as MPFL reconstruction. The decision to add a distal realignment procedure of tibial tubercle transfer is based on severity of patellar instability judged on either TTTG distance or arthroscopic patellofemoral tracking. We set out to validate our use of arthroscopic patellofemor...

The surgical management of patellofemoral instability: when is an isolated medial patellofemoral ligament reconstruction indicated?

Current Orthopaedic Practice | 2016 | Neil Jain

Many factors contribute to patellofemoral instability. Surgical intervention may include additional procedures to reconstruct the medial patellofemoral ligament (MPFL). This review attempts to ascertain from the literature whether there is a threshold for when an isolated MPFL reconstruction will suffice and when an additional procedure would be required.
