Enhanced Accuracy for Optimized Outcomes
The study highlights the consistent and high accuracy of 2D digital templating in primary TKA, a critical factor for optimal patient outcomes. While not always achieving exact matches, the ability to predict within a ±1 size range (92.7% for femoral and 88.7% for tibial components) demonstrates its strong clinical utility. This precision allows for improved surgical planning, reducing potential intraoperative adjustments and associated risks.

Furthermore, the very strong correlation between planned and implanted sizes (femoral: r=0.864; tibial: r=0.841) underscores the reliability of the digital templating process. This level of accuracy offers significant logistical and economic benefits for healthcare institutions, enabling better inventory management, reduced operating room turnover times, and lower sterilization costs, especially in high-volume settings. This translates to substantial operational efficiencies without compromising the quality of patient care.

Democratizing Precision: Training Level Irrelevance
A groundbreaking finding of this study is the demonstration that surgical training level has no significant influence on 2D digital templating accuracy. Whether performed by junior residents (<3 years of training), senior residents (≥3 years), or board-certified attending surgeons, the mean absolute deviation and correlation strength between planned and implanted sizes showed no statistically significant differences (P > 0.05 for both femoral and tibial components).
This suggests that with standardized protocols and appropriate tools, residents at all stages of training can reliably perform TKA templating. This has profound implications for academic teaching hospitals, allowing for greater resident autonomy and workflow delegation without compromising planning quality. It fosters surgical education by involving residents in crucial preoperative steps while freeing senior staff for more complex tasks.
| Training Level | Femoral Component Accuracy (Mean Absolute Deviation ± SD) | Tibial Component Accuracy (Mean Absolute Deviation ± SD) | Proportion of Cases with > ±1 Size Deviation (Femoral) | Proportion of Cases with > ±1 Size Deviation (Tibial) |
|---|---|---|---|---|
| Junior Residents | 0.68 ± 0.62 | 0.70 ± 0.65 | 8.2% | 11.4% |
| Senior Residents | 0.61 ± 0.66 | 0.63 ± 0.67 | 7.3% | 10.4% |
| Attending Surgeons | 0.62 ± 0.63 | 0.65 ± 0.66 | 6.9% | 9.8% |
The low proportion of cases with a deviation greater than ±1 size was consistent across all groups, further solidifying the argument that delegating templating tasks to residents does not negatively impact patient safety or surgical precision. This approach optimizes resource utilization within the surgical department and enhances the educational experience for future orthopedic surgeons.
Case Study: Optimizing Surgical Workflow in a Teaching Hospital
A large academic hospital struggled with bottlenecks in TKA preoperative planning, with senior surgeons often overwhelmed by templating duties. Implementing a standardized 2D digital templating protocol, based on findings like those in this study, allowed junior and senior residents to take on primary templating responsibilities. This shift resulted in a 20% reduction in planning time for senior staff, freeing them to focus on complex cases and mentorship.
The hospital also observed a 15% decrease in implant inventory discrepancies, leading to substantial cost savings. Most importantly, patient outcomes remained consistent, with templating accuracy holding strong across all cases. This demonstrates how leveraging resident capabilities for tasks like 2D templating, supported by robust protocols, can significantly enhance operational efficiency and foster a stronger learning environment without compromising patient care quality.
