Summary
This case report details acute patellar dislocation with unusual rotation, successfully treated with open reduction. One year post-surgery, the patient experienced good knee function and pain relief.
Area of Science:
- Orthopedic Surgery
- Knee Biomechanics
Background:
- Acute patellar dislocation is a common knee injury.
- Complex dislocations involving patellar rotation present unique challenges in diagnosis and treatment.
Observation:
- A case of acute patellar dislocation with significant vertical and longitudinal rotation of the patella is presented.
- The unique rotation caused the patellar articular surface to face outward and the dorsal surface to face the femoral condyle.
Findings:
- Open reduction was performed to address the complex patellar dislocation.
- One year following open reduction and soft-tissue repair, the patient demonstrated acceptable knee function.
- The patient reported no knee pain one year after the surgical intervention.
Implications:
- Open reduction is an effective treatment for complex patellar dislocations with rotational components.
- This case highlights the importance of accurate diagnosis and tailored surgical techniques for optimal patient outcomes in patellar instability.
- Successful management can restore knee function and alleviate pain in patients with severe patellar dislocations.
