Summary
This case study details successful treatment of an open knee dislocation with a periprosthetic patellar fracture using tension band wiring and rehabilitation. Adequate bone stock supports internal fixation for such complex knee injuries.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Biomedical Engineering
Background:
- Open knee dislocations are severe injuries often requiring complex management.
- Periprosthetic patellar fractures present unique challenges, especially in conjunction with dislocations.
- Literature review indicates historically unpredictable outcomes for internal fixation of these fractures.
Purpose of the Study:
- To present a unique case of open knee dislocation with a periprosthetic patellar fracture.
- To describe the successful treatment of this combined injury.
- To review current literature on managing periprosthetic patellar fractures.
Main Methods:
- Case report of a patient with open knee dislocation and periprosthetic patellar fracture.
- Surgical treatment utilizing tension band wiring.
- Implementation of a conservative rehabilitation program.
Main Results:
- Satisfactory treatment outcome achieved for the patient.
- Demonstrated the viability of tension band wiring for this specific injury pattern.
- Highlighted the importance of adequate patellar bone stock for fixation.
Conclusions:
- Tension band wiring and conservative rehabilitation can effectively manage open knee dislocations with periprosthetic patellar fractures.
- Internal fixation is a viable option for periprosthetic patellar fractures when sufficient bone stock is present.
- This case adds to the understanding of treating complex knee trauma involving prosthetic components.
