Concomitant Patellar Tendon Reconstruction With Hamstring Autografts and Medial Patellofemoral Ligament Reconstruction With Quadriceps Autograft in the Setting of Severe Patellar Tendinopathy With Recurrent Lateral Patellar Instability

Arthroscopy Techniques
Chronic injuries to the extensor mechanism present unique challenges to physicians because of their complex nature and the need for a multifactorial treatment approach.

Rethinking Knee Arthroplasty: Bicompartmental Unicompartmental Knee Arthroplasty as a Biomechanically Personalized, Function‐Preserving Solution for Knee Osteoarthritis

Orthopaedic Surgery, EarlyView.
A comparative study of bicompartmental unicompartmental knee arthroplasty (bi‐UKA) and total knee arthroplasty (TKA) in patients with bicompartmental osteoarthritis. The image illustrates key anatomical differences in implant design, outlines the study population (bi‐UKA: n = 35, TKA: n = 45), and highlights functional evaluation metrics including the ...

Concurrent Validation of the Banff Patella Instability Instrument to the Norwich Patellar Instability Score and the Kujala Score in Patients With Patellofemoral Instability

Orthopaedic Journal of Sports Medicine, 2016
Background: The Banff Patella Instability Instrument (BPII) is a disease-specific, patient-reported, quality-of-life outcome measure designed to assess patients with patellofemoral instability.

Kinematic Alignment in TKA Using the Contralateral Healthy Knee as Reference: A Combined Finite Element and Clinical Analysis

Orthopaedic Surgery, EarlyView.
In patients with unilateral knee osteoarthritis, a novel natural kinematic alignment (NKA) using the contralateral healthy knee as reference was compared with mechanical alignment (MA) and kinematic alignment (KA) via finite element analysis and a clinical study. NKA provided more balanced stress in neutral/mild varus models.

The role of arthroscopic release of gluteal muscle contracture in improving patellofemoral instability

Journal of Orthopaedic Surgery and Research, 2019
Background Gluteal muscle contracture (GMC) is a notable problem in some developing countries and includes features such as a snapping sound of the hip, abnormal gait, and unusual posture when patients squat with the knees together.

Management of increased posterior tibial slope in ACL deficiency: A narrative review and recommendation of the Osteotomy Committee of the German Knee Society

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 34, Issue 10, Page 3586-3604, October 2026.
Abstract Increased posterior tibial slope (PTS) is a known risk factor for anterior cruciate ligament (ACL) deficiency and graft failure after ACL reconstruction (ACLR). Although many studies investigated different aspects related to the PTS, there is still a lack of comprehensive recommendations and practical guidelines, especially with regard to ...

Comparable clinical outcomes and redislocation rates after isolated medial patellofemoral ligament reconstruction in patients with and without borderline anatomical risk factors for patellar instability

Journal of Experimental Orthopaedics, Volume 13, Issue 4, October 2026.
Abstract Purpose The purpose of this study was to compare mid‐ to long‐term clinical outcomes and redislocation rates after isolated medial patellofemoral ligament (MPFL) reconstruction in patients with and without borderline anatomical risk factors. It was hypothesized that isolated MPFL reconstruction would provide comparable outcomes regardless of ...

Mapping Fatty Acid Composition in the Human Knee: Short‐Term Repeatability at 3T

Journal of Magnetic Resonance Imaging, Volume 64, Issue 4, Page 1066-1076, October 2026.
ABSTRACT Background Alterations in periarticular lipid composition are implicated in musculoskeletal diseases, yet short‐term reliability of MRI‐based triglyceride composition mapping in the knee is not fully established. Purpose To evaluate 1‐week repeatability of proton‐density fat fraction (PDFF) and triglyceride fatty‐acid composition—saturated ...

Anatomical and clinical significance of the Cyrano long-nosed patella in combination with patellofemoral instability: a case report and review of literature

Journal of Medical Case Reports
Background The combination of a long-nosed patella and patella alta can lead to symptoms such as anterior knee pain and patellofemoral instability. Purpose Our objective was to address this uncommon, multifactorial cause of patellar pain and instability ...

Anterior Compartment Sparing Tibial Tubercle Osteotomy Using Back-Cut Technique

Arthroscopy Techniques
Tibial tubercle osteotomy (TTO) is a surgical technique commonly indicated for patellofemoral instability and/or patellar chondral repair. In select patients, soft tissue procedures alone (medial patellofemoral ligament reconstruction) are not sufficient
