Summary
The direct anterior approach (DAA) for total hip arthroplasty (THA) shows a learning curve, with complications decreasing after about 80 cases. Patient selection is key for successful DAA outcomes.
Area of Science:
- Orthopedic Surgery
- Surgical Techniques
Background:
- The direct anterior approach (DAA) for total hip arthroplasty (THA) is increasingly adopted globally.
- Limited research exists on DAA in Southern and Southeast Asia.
- Surgeon experience and patient selection are crucial for DAA success.
Purpose of the Study:
- To evaluate the learning curve and outcomes of the direct anterior approach (DAA) for total hip arthroplasty (THA).
- To assess the impact of surgeon experience on intraoperative variables and complications.
- To investigate functional outcomes and identify the learning curve threshold for DAA in a specific Asian population.
Main Methods:
- Prospective study of 157 patients undergoing THA via DAA (January 2019 - June 2022).
- Patients divided into three comparative groups.
- Cumulative summation (CUSUM) method used to analyze surgeon learning curve and performance.
Main Results:
- Significant improvement in functional outcomes observed across groups.
- Intraoperative variables and complication rates varied among groups, with improvements noted in later cases.
- Learning curve analysis indicated consistent success after the 82nd case and an acceptable failure rate by the 118th case.
Conclusions:
- DAA offers benefits for THA, but a significant learning curve exists.
- Complication rates initially high, decreased substantially after approximately 80 cases.
- Careful patient selection is critical to minimize challenging cases and optimize DAA outcomes.
