Superior-lateral patella dislocation with rotation along its vertical axis
Background
Patellar dislocations are common, but superior-lateral dislocation with vertical axis rotation is rare and challenging to reduce.
Case Presentation
A woman in her 20s presented with left knee pain and deformity after minor trauma. Traditional reduction attempts failed due to a vertical rotational component. Reduction was achieved using a technique involving hip flexion, a modified varus–valgus force, and knee extension.
Conclusion
Emergency clinicians must recognize complex patellar dislocations and consider early orthopedic consultation to minimize complications.
