Double‐Limbed Medial Patellofemoral Ligament Reconstruction Using Knotless Femoral Fixation Technique

Arthroscopy Techniques, EarlyView.
Abstract This technical note describes using knotless femoral fixation for medial patellofemoral ligament reconstruction for skeletally immature patients. Using a knotless anchor for epiphyseal femoral fixation in the skeletally immature decreases the risk of irritable interference screw fixation and optimizes graft contact with host bone.

Allograft Medial Patellofemoral Ligament Reconstruction Using Patellar Suture Anchors and Stepwise Medial Imbrication

Arthroscopy Techniques, EarlyView.
Abstract Patellar instability commonly affects adolescents and young athletes and is associated with injury to the medial patellofemoral ligament (MPFL). MPFL reconstruction is a well‐established treatment for recurrent instability; however, complications related to graft tensioning, fixation, and incomplete restoration of medial soft‐tissue restraints

Vastus medialis motor unit properties in knee osteoarthritis [PDF]

BMC Musculoskeletal Disorders, 2011
Maximal isometric quadriceps strength deficits have been widely reported in studies of knee osteoarthritis (OA), however little is known about the effect of osteoarthritis knee pain on submaximal quadriceps neuromuscular function. The purpose of this study was to measure vastus medialis motor unit (MU) properties in participants with knee OA, during ...

Arthroscopic and Mini‐Open Combined Medial Patellofemoral Ligament and Medial Patellotibial Ligament Reconstruction for J‐Sign‐Positive Patellar Dislocation

Arthroscopy Techniques, EarlyView.
Abstract This technical note addresses recurrent patellar instability with a positive J‐sign and describes a minimally invasive, arthroscopic and mini‐open approach that combines medial patellofemoral ligament and medial patellotibial ligament reconstruction with extensive lateral retinacular release, positioned as a preferred or transitional option ...

Open Lateral Retinacular Lengthening During an “À La Carte” Step‐by‐Step Surgical Approach for Habitual Patellar Dislocation

Arthroscopy Techniques, EarlyView.
Abstract Habitual patellar dislocation is rare and primarily characterized by superolateral soft‐tissue contractures. The surgical approach described focuses on a step‐by‐step, “à la carte”, release of these contractures. The algorithm and technique described here offer a reproducible surgical strategy applicable to both skeletally immature and mature ...

Acute Changes in Muscle Contractile Properties Following Specific Training Load in Elite Kickboxers: A pilot study [PDF]

Journal of Kinesiology and Exercise Sciences
Background. Acute neuromuscular responses to training are key for optimizing performance and mitigating injury risk. This study evaluated immediate changes in muscle contractile properties after a sport-specific load in elite kickboxers. Methods.

Patellar Tendon Revision Reconstruction Using Transosseous Patella All‐Suture Anchors, Semitendinosus Autograft, and Achilles Allograft

Arthroscopy Techniques, EarlyView.
Abstract Patellar tendon rupture is an uncommon but highly treatable injury, with excellent repair outcomes and low reoperation rates. Chronic patellar tendon ruptures or repair failures pose a clinical challenge, but the success rates of reconstruction with extensor mechanism allograft or autograft are reported to be high in the literature. Still, the

Differences in the mass and quality of the quadriceps with age and sex and their relationships with knee extension strength

Journal of Cachexia, Sarcopenia and Muscle, 2021
Background Although muscle quality evaluations are currently considered important for diagnosing sarcopenia, data from the general population are lacking.

MR Imaging‐Based Biomarkers for Strength Prediction: A Statistical Shape and Architecture Modeling of Quadriceps Muscles

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Muscle mass decline, associated with strength decline, is a hallmark of aging. Yet, strength decline greatly exceeds mass decline. This indicates that aspects of muscle quality and architecture—not reflected by mass—also influence force generating capacity.
