Association of patellofemoral morphology and alignment with the radiographic severity of patellofemoral osteoarthritis
BackgroundRisk factors for the severity of patellofemoral osteoarthritis (PFOA) are poorly understood. This research aims to evaluate the association...

Medial patellofemoral ligament reconstruction is superior to active rehabilitation in protecting against further patella dislocations
PurposeIsolated reconstruction of the medial patellofemoral ligament (MPFL-R) has become the predominant stabilizing procedure in the treatment of...

Return to sports and short-term follow-up of 101 cases of medial patellofemoral ligament reconstruction using gracilis tendon autograft in children and adolescents
IntroductionAn acute patellofemoral dislocation is the most common acute knee injury in children. Recent studies suggest up to 40% of immature...
-
Medial patellofemoral ligament reconstruction combined with derotational distal femoral osteotomy yields better outcomes than isolated procedures in patellar dislocation with increased femoral anteversion
PurposeThe purpose of this study was to evaluate and compare clinical and radiological outcomes between isolated medial patellofemoral ligament...

Low re-dislocation rate following Bereiter trochleoplasty for recurrent patellar instability with severe trochlear dysplasia
PurposeTrochlear dysplasia is an independent risk factor for recurrent patellar instability with evidence demonstrating its presence in up to 85% of...

Effect of instrument-assisted soft tissue mobilization combined with blood flow restriction training on function, pain and strength of patients with patellofemoral joint pain
BackgroundPatellofemoral pain syndrome is a prevalent sports injury that affects athletes both in their daily lives and during training. This...

Outcomes and reoperation rates after tibial tubercle transfer and medial patellofemoral ligament reconstruction: higher revision stabilization in patients with trochlear dysplasia and patella alta
PurposeTo determine the reoperation rate, risk factors for reoperation, and patient-reported outcomes after isolated or combined tibial tubercle...
-
Medial patellofemoral ligament reconstruction using nonresorbable sutures yields comparable outcomes to reconstruction with a pedicled quadriceps tendon autograft when performed in addition to bony risk factor correction
PurposeTo evaluate the results for reconstruction of the medial patellofemoral ligament using synthetic nonresorbable sutures (S-MPFL-R) in...

Medial patellofemoral ligament MRI abnormalities in the setting of MCL injuries: are they clinically relevant?
ObjectiveTo assess MRI abnormalities of the medial patellofemoral ligament (MPFL) in patients with clinically and MRI-proven superficial medial...

Effect of medial open wedge high tibial osteotomy on progression of patellofemoral osteoarthritis
PurposeThis study aimed to investigate the effect of medial open wedge high tibial osteotomy (MOWHTO) on patellofemoral joint osteoarthritis (PF OA)...
-
A decreased tibial tuberosity-trochlear groove distance is associated with lateral patellofemoral joint degeneration after implantation of medial fixed-bearing unicompartmental knee arthroplasty — a minimum five year follow-up
PurposeThe influence of lateral patellofemoral osteoarthritis (PFOA) in medial unicompartmental knee arthroplasty (UKA) is controversial. Our aim was...
-
The winking sign is an indicator for increased femorotibial rotation in patients with recurrent patellar instability
PurposeRotation of the tibia relative to the femur was recently identified as a contributing risk factor for patellar instability, and correlated...

Anatomic medial patellofemoral ligament (MPFL) reconstruction with and without tibial tuberosity osteotomy for objective patellar instability
PurposeThe aim of this study was to evaluate the clinical outcomes of patients treated with anatomic medial patellofemoral ligament (MPFL)...

Assessments of early patellofemoral joint osteoarthritis features after anterior cruciate ligament reconstruction: a cross-sectional study
BackgroundPersistent anterior knee pain and subsequent patellofemoral joint (PFJ) osteoarthritis (OA) are common symptoms after anterior cruciate...
-
The incidence of complications after derotational femoral and/or tibial osteotomies in patellofemoral disorders in adolescents and active young patients: a systematic review with meta-analysis
PurposeTo quantify the risk of perioperative and postoperative complications of derotational femoral and/or tibial osteotomies in patellofemoral...
-
Reconstruction of the medial patellofemoral ligament with nonresorbable suture tape normalizes patellar maltracking independent of patella-side fixation technique
PurposePatellar maltracking caused by a rupture of the medial patellofemoral ligament (MPFL) can be improved by MPFL reconstruction (MPFL-R) with a...
-
Combined medial patellofemoral and medial patellotibial reconstruction for patellar instability: a PRISMA systematic review
BackgroundThe medial patellofemoral ligament (MPFL) works in association with the medial patellotibial ligament (MPTL) and the medial patellomeniscal...

Effects of alendronate on cartilage lesions and micro-architecture deterioration of subchondral bone in patellofemoral osteoarthritic ovariectomized rats with patella-baja
BackgroundPatellofemoral osteoarthritis (PFJOA) is a subtype of knee OA, which is one of the main causes of anterior knee pain. The current study...
-
Early patellofemoral articular cartilage degeneration in a rat model of patellar instability is associated with activation of the NF-κB signaling pathway
BackgroundPatellar instability (PI) often increases the possibility of lateral patellar dislocation and early osteoarthritis. The molecular mechanism...
