Summary
This study followed 31 primary cemented total hip arthroplasties for over 10 years. Results show significant improvement in hip function, with non-inflammatory conditions yielding better long-term outcomes.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
Background:
- Primary cemented total hip arthroplasty (THA) is a common procedure for hip conditions.
- Long-term follow-up data on cemented THA in the Indo-Asian population is limited.
- This study presents a 10-year follow-up of primary cemented THA outcomes in Indian patients.
Purpose of the Study:
- To evaluate the long-term efficacy and outcomes of primary cemented total hip arthroplasty.
- To assess implant longevity and procedural success over a decade.
- To compare outcomes between inflammatory and non-inflammatory hip conditions.
Main Methods:
- A cohort of 31 hips in 30 patients underwent primary cemented THA.
- Follow-up extended to a minimum of 10 years (mean 12.7 years).
- Clinical outcomes were assessed using the Harris hip score and serial radiographs.
Main Results:
- Significant improvement in Harris hip scores was observed, from a mean of 29.2 preoperatively to 79.9 postoperatively.
- Patients with non-inflammatory conditions demonstrated more sustained functional improvement compared to those with inflammatory conditions.
- Complications included hypotension, limb shortening, superficial infection, and prosthesis malposition.
Conclusions:
- Primary cemented THA provides significant long-term functional improvement for Indo-Asian patients.
- Outcomes may differ between inflammatory and non-inflammatory etiologies.
- Revision rates may be lower in this population due to factors like pain tolerance and financial constraints.
