Lateral Patellotibial Ligament Reconstruction for Medial Patellar Instability

, 2014
Medial patellar instability, though infrequently recognized, can be a disabling complication of a lateral retinacular release. Patients with persistent anterior knee pain and instability after lateral release should be evaluated closely.

Increasing meniscal repair rates during ACL reconstruction did not increase reoperation risk: An analysis of surgical trends from 2015 to 2023

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To evaluate surgical trends over time in meniscal procedures during anterior cruciate ligament reconstruction (ACLR) and compare meniscal reoperation rates and subjective outcomes between 2015–2019 and 2020–2023. Methods This study included 2748 knees undergoing primary ACLR with concomitant meniscal procedures at Capio Artro Clinic ...

Combined Sulcus Deepening Trochleoplasty, Varus Distal Femoral Osteotomy, and Medial Patellofemoral Ligament Reconstruction for Recurrent Patellar Instability with Trochlear Dysplasia, Genu Valgum, and Medial Patellofemoral Ligament Tear

Journal of Orthopaedic Case Reports
Introduction: Patellar instability is a complex condition that may be caused by a variety of factors. This case report discusses a case of recurrent patellar instability due to genu valgum, trochlear dysplasia, and medial patellofemoral ligament (MPFL ...

Increased Magnetic Resonance Imaging Signal of the Lateral Patellar Facet Cartilage: A Functional Marker for Patellar Instability?

, 2017
Background:In the knee joint, predisposition for patellar instability can be assessed by an abnormal Insall-Salvati index, tibial tuberosity–trochlear groove (TTTG) distance, and abnormal shape of patella and trochlea. Given the complex anatomic features

Similar revision rates after ACL reconstruction with hamstring tendon or bone–patellar tendon–bone autografts in young females: Results from the Swedish knee ligament registry

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare subjective knee function and revision rates at the 5‐year follow‐up in young females (14–25 years) undergoing primary anterior cruciate ligament reconstruction (ACLR) with either hamstring tendon (HT) or bone–patellar tendon–bone (BPTB) autografts in a nationwide registry‐based cohort.

Allograft use and fixed suspensory fixation increase revision risk in multiple revision anterior cruciate ligament reconstruction: A Swedish knee ligament registry study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The purpose of this study was to assess the association between surgical‐related variables, revision‐free survival and knee injury and osteoarthritis outcome score (KOOS) following multiple revision anterior cruciate ligament reconstruction (mrACLR) using data from a national knee ligament registry.

Combined Distal Femoral Osteotomy and Medial Patellofemoral Ligament Reconstruction for Patellar Instability and Genu Valgus: A Case Report and Literature Review

Orthopaedic Surgery
Background Medial patellofemoral ligament (MPFL) reconstruction alone is not effective for patellar instability associated with anatomic abnormalities of lower limbs.

Radiographic assessment in patellar instability and chondromalacia patellae

, 1986
Minor degrees of malalignment of the patella and anatomical abnormalities including a flattened sulcus angle and an increased ratio between patellar tendon length and patellar length (PT:P) have been suggested as predisposing factors in the causation of

Quadriceps malalignment is strongly associated with recurrent patellofemoral instability in native knees

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Patellofemoral instability (PFI) has been associated with multiple anatomical risk factors. The recent development of accurate quadriceps muscle measurements using three‐dimensional imaging techniques have demonstrated that quadriceps alignment is highly variable and frequently leads to a lateralised force vector on the patella.

The relationship between quadriceps angle and tibial tuberosity–trochlear groove distance in patients with patellar instability

, 2012
Purpose The quadriceps angle (Q-angle) represents the angle between the vector of action of the quadriceps and the patellar tendon. An increased Q-angle has been associated with an increased risk of patellar instability, although there is disagreement
