Summary
Hip resurfacing had more early complications and reoperations than cementless total hip arthroplasty (THA) during the learning curve. However, both hip procedures showed similar clinical outcomes at 5-year follow-up.
Area of Science:
- Orthopedic Surgery
- Arthroplasty Research
- Surgical Outcomes Analysis
Background:
- Hip resurfacing presents an alternative surgical option to traditional total hip arthroplasty (THA).
- Evaluating new surgical techniques during their initial implementation is crucial for patient safety and procedural refinement.
Purpose of the Study:
- To compare the early clinical results of hip resurfacing with cementless total hip arthroplasty (THA) performed by an experienced hip surgeon.
- To assess the learning curve associated with hip resurfacing by analyzing complication and reoperation rates.
Main Methods:
- A comparative study involving 55 hip resurfacing procedures and 100 cementless THAs with a cylindrical tapered femoral stem.
- Evaluation of the learning curve through analysis of reoperation incidence, complications, Harris Hip Scores (HHS), and implant survivorship.
Main Results:
- Hip resurfacing demonstrated a significantly higher reoperation rate (14.5%) compared to THA (4%).
- No significant difference was observed in the overall complication rates between the two groups.
- While preoperative Harris Hip Scores (HHS) were similar, final mean HHS at 5-year follow-up were comparable for both hip resurfacing and THA.
Conclusions:
- Initial experience with hip resurfacing is associated with earlier and more frequent operative complications compared to cementless THA.
- Despite early challenges, hip resurfacing achieves similar clinical outcomes to THA at the 5-year follow-up mark.
