Summary
Computer navigation in total knee arthroplasty (TKA) may improve implant accuracy. However, pin fixation for reference arrays can cause complications, as illustrated by a case of vascular injury during navigated TKA.
Area of Science:
- Orthopedic Surgery
- Medical Technology
- Surgical Complications
Background:
- Computer navigation offers potential benefits for implant positioning in total knee arthroplasty (TKA).
- Reference array fixation using pins is a common method in navigated procedures.
- Pin insertion carries inherent risks, including potential vascular complications.
Purpose of the Study:
- To report a specific case of vascular injury.
- To highlight a potential complication associated with navigated TKA.
- To inform surgeons about risks associated with femoral pin placement.
Main Methods:
- Case report of a navigated total knee arthroplasty.
- Focus on the complication arising from femoral pin insertion.
- Description of the vascular injury encountered.
Main Results:
- A vascular injury occurred during the insertion of a femoral pin.
- This complication was directly related to the use of computer navigation fixation.
- The case underscores a specific risk of navigated TKA procedures.
Conclusions:
- Femoral pin fixation in navigated TKA can lead to serious complications such as vascular injury.
- Careful consideration and technique are necessary during pin placement.
- This case emphasizes the importance of awareness regarding potential iatrogenic injuries in computer-assisted surgery.
