In 101 patients with high-grade trochlear dysplasia undergoing trochleoplasty plus MPFL reconstruction, a higher preoperative sagittal TT-TG distance was independently associated with better function, less pain, and higher BPII 2.0 scores, though explanatory power was modest.
TT-PCL distance was greater in patellar instability patients than controls at all axial levels, but values vary with dorsal condylar line placement; normalizing to tibial width reduces variability and discrimination is only modest.
Management of first-time patellar dislocation: The ESSKA 2024 formal consensus-Part 2.
ESSKA consensus on first-time patellar dislocation favors individualized care, MPFL reconstruction over repair when surgery is needed, physical therapy for all patients, and no clear long-term benefit from bracing.
A scoping review found major inconsistency in how studies define patellar dislocation patients by osseous risk factors and rarely use dislocation-specific patient-reported outcome measures, complicating treatment comparisons.
Management of first-time patellar dislocation: The ESSKA 2024 formal consensus-Part 1.
This ESSKA 2024 consensus establishes 13 expert-agreed statements on diagnosis and imaging for first-time patellar dislocation, emphasizing MRI's role and the high burden of ongoing symptoms beyond instability alone.
Literature review finds proximal patellar realignment and MPFL reconstruction give similar recurrent dislocation and arthritis rates, with realignment cheaper and fewer complications, so it remains a reasonable option for patellar instability.
A Scientometric Analysis of Studies on Patellar Dislocation.
Scientometric analysis identifies medial patellofemoral ligament reconstruction, risk factors, and pediatric cases as major research themes in patellar dislocation literature.
Review confirms MPFL reconstruction reliably prevents recurrent lateral patellar dislocation, and rehab (operative or nonoperative) should target pain/edema resolution, motion, and hip/knee strengthening before return to sport.
Medial Patellofemoral Ligament Reconstruction: Indications, Technique, and Outcomes.
Review outlines that MPFL reconstruction restoring native anatomy and isometry yields good outcomes for recurrent patellar instability, with graft choice being less critical than technique.
Factors of patellar instability: An anatomic radiographic study
This anatomic-radiographic study identifies trochlear dysplasia, quadriceps dysplasia, patella alta, and increased TT-TG distance as the four key multifactorial contributors to patellar instability, guiding targeted surgical correction.
Epidemiology and Natural History of Acute Patellar Dislocation
Prospective cohort of 189 patients found young females with prior instability history had far higher recurrence risk after patellar dislocation than first-time dislocators, aiding risk counseling.
Acute Patellar Dislocation in Children: Incidence and Associated Osteochondral Fractures
In a prospective Finnish cohort, acute pediatric patellar dislocation had an annual incidence of 43/100,000 and caused osteochondral fractures in 39% of knees, mostly after spontaneous relocation.
Trochlear dysplasia, skeletal immaturity, patella alta (CDI>1.45), and prior contralateral dislocation predict recurrent patellar instability after first-time dislocation, with risk rising sharply as risk factors accumulate.
