Intra-articular dislocation of the patella

Area of Science:

• Orthopedic Surgery
• Geriatric Medicine
• Emergency Medicine

Background:

• Chronic, irreducible intra-articular patellar dislocation is a rare condition.
• This case involves an elderly nursing home resident with prolonged inability to weight bear.

Purpose of the Study:

• To report an unusual case of chronic, irreducible intra-articular patellar dislocation in an elderly patient.
• To discuss the diagnostic and management challenges of such a rare presentation.

Main Methods:

• Case report detailing clinical presentation and radiographic findings.
• Description of failed closed reduction attempts.
• Surgical intervention with open reduction under general anesthesia.

Main Results:

• Radiographs confirmed intra-articular dislocation with the patella lodged in the intercondylar notch.
• Two closed reduction attempts were unsuccessful.
• Open reduction was ultimately required for successful treatment.

Conclusions:

• Chronic, irreducible intra-articular patellar dislocation can occur in the elderly.
• Management may necessitate surgical intervention, even in frail patients.
• This case underscores the importance of prompt diagnosis and appropriate treatment for patellar dislocations.
