Patient-specific instrumentation is associated with more accurate and less time-consuming total knee arthroplasty surgeries, according to a study published in Knee Surgery, Sports Traumatology, Arthroscopy.
The researchers compared the operative outcomes of 47 TKA patients whose procedures used patient-specific instrumentation with the outcomes of 48 TKA patients who used standard instrumentation.
Here's what you need to know:
1. When comparing the efficacy of the two procedures, the researchers found that patient-specific instrumentation had a low rate of intraoperative adjustments.
2. When comparing blood loss, the researchers found that the patient-specific instrumentation group had spent significantly fewer blood units.
3. When comparing surgical time, the researchers found that patient-specific instrumentation was associated with a 24.8 percent reduction in operation time.
4. The researchers also found that patient-specific instrumentation showed a half-day reduction in length of stay.
